+SEX is a F*EX companion: Stream EXchange
+
+You can imagine SEX as network wide UNIX pipes with a relay between. This
+can be usefull for piping data from A to B where A and B cannot establish
+a direct connection, but both can connect by HTTP to the SEX-server. SEX
+is a synchronous service in conjuction to F*EX which is asynchronous.
+
+For seamless integration into the UNIX tool chain, there are the
+shell-tools sexsend and sexget.
+
+Using web browsers for sexing will not work, because they cannot handle
+streams in a pipe. So far, there are only the UNIX clients. Feel free to
+implement other clients for other operating systems :-)
+
+Authentication is the same as with F*EX.
+
+Example:
+
+root@lanldap:/var/log: tail -f syslog | sexsend framstag@rus.uni-stuttgart.de
+
+framstag@blubb:/tmp: sexget | grep ldap
+
+
+If you need encryption, then use the standard UNIX toolbox and add a
+appropriate program to the pipe, for example: openssl bf
+
+
+Tips for using SEX for file exchange:
+
+I have a lot of (administrative) accounts on even more hosts, where I have
+to exchange a lot or big files. These hosts often cannot make direct
+tcp-connects to each other, because of IP-filters, firewalls or missing
+server software. Only outgoing connections are possible.
+
+Therefore NFS, ssh or even ftp are no option.
+
+Since today my solution was F*EX:
+
+1) on source host send the files within a container to the F*EX-server:
+
+	fexsend -a container.tar file1 file2 ... .
+
+2) read or copy the FEXURL with mouse
+
+3) on destination host get container.tar from F*EX-server and extract it:
+
+	fexget FEXURL 
+	tar xvf container.tar
+	rm container.tar
+
+
+Backdraws:
+
+- a lot of manually work
+- creation of container.tar needs (a lot of) time
+- container.tar needs (too much) disk space on source and destination host
+  and on the F*EX-Server
+  
+
+Small solution:
+
+Usage of xx (wrapper for fexsend) eliminates manually handling of
+container.tar. But it will be still created, only automatically.
+The ressource problems are still there.
+
+
+The new sexy solution:
+
+I use SEX (Stream EXchange) instead of FEX (File EXchange)!
+
+There is no more a temporary container.tar, but the files are transfered
+as a stream with the new client sexxx!
+
+An example (*):
+
+On the source host:
+
+	root@obertux:~/bin# sexxx .
+	streaming:
+	./
+	./autopatch
+	./subsys
+	./pwsync
+	./cspread
+	./fspread
+	./spread
+	./iptconf
+	./esxbackup
+	./esxlist
+	./getxx
+	./rscreen
+
+
+On the destination host:
+
+	framstag@flupp:/tmp: sexxx
+        extracting from stream:
+	drwxr-xr-x root/root         0 2010-08-06 12:48 ./
+	-rwxr-xr-x framstag/users  170 2010-01-20 13:26 ./autopatch
+	-rwxr-xr-x root/root       336 2006-02-02 15:15 ./subsys
+	-rwxr-xr-x root/root       278 2010-01-18 23:38 ./pwsync
+	lrwxrwxrwx root/root         0 2009-11-03 15:49 ./cspread -> spread
+	lrwxrwxrwx root/root         0 2009-11-03 15:49 ./fspread -> spread
+	-rwxr-xr-x root/root     10354 2010-02-12 14:49 ./spread
+	-rwxr-xr-x root/root      1380 2010-01-14 08:54 ./iptconf
+	-rwxr-xr-x root/root       116 2010-05-04 18:36 ./esxbackup
+	-rwxr-xr-x root/root       344 2010-05-06 13:33 ./esxlist
+	-rwxr-xr-x root/root        93 2010-08-06 12:32 ./getxx
+	-rwxr-xr-x 1000/users      173 2009-11-26 13:40 ./rscreen
+
+
+Now I can transfer any files from a new installed (VM) server to my
+admin workstation behin a firewall. Or the other direction.
+
+
+(*) The example above has only a few kB, but one can use sexxx for many GB
+    or even TB!
+    On my VMs I get a throughput of 90 MB/s.

+F*EX (Frams' Fast File EXchange) is a service to send big (large, huge, giant,
+...) files from a user A to a user B, anywhere on the internet.
+
+The sender uploads the file to the F*EX-server and the recipient automatically
+gets a notification email with a download-URL.
+
+Main features of F*EX
+
+  * file transfer of virtually unlimited file size
+  * recipient and sender only need an email program and a web browser - of any
+    kind, they do not have to install any software
+  * RESEND and REGET for resuming after link failures at last sent byte
+  * auto-notification of recipient
+  * auto-deletion after download
+  * auto-deletion after expiration date (default: 5 days)
+  * full-users can create one time upload URLs for foreign users
+  * full-users can create subusers, who can send only to this full-user
+  * full-users can create groups, an analogy to mailing lists, but for files
+  * self registration possible for internal and external users
+  * maintenance-free: no admin interaction necessary 
+  * sending to multiple recipients needs storage on the server only once
+  * quotas for sending and receiving
+  * F*EX is a HTTP web-service and needs no firewall-tunnels
+  * support for (personal or public) streams, too (SEX : Stream EXchange)
+  * for real UNIX users, there are the shell programs fexsend and fexget to
+    avoid annoying web browser usage and for full scripting support
+  * adminstration by CLI or Web
+  * about 10 times faster than apache
+  * authentification modules for LDAP, RADIUS, POP, mailman
+  * server based user address books
+  * (reverse) proxy support
+  * "public upload" similar to "anonymous ftp" possible
+  * "anonymous upload" without registration for enabled IP addresses possible
+  * localization for many languages
+  * authentification by local user database, RADIUS, LDAP, mailman or POP
+  * user and admin can throttle bandwith usage
+  * admin can restrict access based on email or IP addresses
+  * server available for UNIX and Windows hosts
+  * protocol and source-code free available
+
+The end user normally uses F*EX with his web browser and the URLs
+http://YOURFEXSERVER/fup (file upload) and http://YOURFEXSERVER/fop (file
+download). 
+
+
+F*EX is not an anonymous service (exception: "public upload" and
+"anonymous upload", see later).
+The admin must register the user with his email address and auth-ID
+string (low security password). This task can be done either with the CLI
+program "fac" (F*EX admin control) or http://YOURFEXSERVER/fac
+
+Alternativly the users can register theirselves with http://YOURFEXSERVER/fur
+(F*EX user registration), if the admin allows them to do so. This is done by
+setting the variables @local_domains and @local_hosts in FEXHOME/lib/fex.ph
+Example: 
+
+	@local_hosts = qw(127.0.0.1 10.10.100.0-10.10.255.255);
+	@local_domains = qw(rus.uni-stuttgart.de flupp.org);
+
+You can also use wildcard "*" in a domain, for example:
+
+	@local_domains = qw(uni-stuttgart.de *.uni-stuttgart.de);
+
+Then all subdomains are allowed.
+
+
+In addition the administrator can allow external users to fex (only) to
+internal users. The F*EX functioning scheme is close related to email
+where any external user can send email to an internal user. This is also
+possible with F*EX. These users are then called "restricted users". The
+administrator has to define via configuration variable @local_rdomains
+the local recipient domains. For example:
+
+@local_rdomains = qw(YOURDOMAIN *.YOURDOMAIN OTHERDOMAIN);
+
+
+F*EX full users can create one time upload URLs with
+http://YOURFEXSERVER/fuc 
+
+With such a URL a foreign user can send this F*EX full user a single file.
+
+F*EX full users can theirselves register "subusers" with
+http://YOURFEXSERVER/fuc 
+
+Subusers can only fex to their full-user, not to any others, and they
+cannot create other subusers.
+
+
+F*EX full users also can create groups, an analogy to mailing lists, but
+for files: every member of a group can send files to the group address.
+
+
+The administrator can set with fac the CAPTIVE flag for a full user. Then
+he cannot change anymore his default settings (KEEP, AUTODELETE, etc)
+
+
+The F*EX user is the same as the "sender" in the fup CGI and the "from"
+parameter in the F*EX URL. 
+
+The (confusing) naming scheme is historically based :-)
+
+
+The recipient (normally) does not need any registration. He authenticates
+himself with his unique download-URL which he gets in the notification
+email.
+
+
+You do not need to build F*EX URLs manually, they are generated by the
+F*EX programs. 
+
+
+A F*EX session is based on unique URL parameters or POST variables (FROM,
+TO, ID, etc). For security reasons the URL parameters FROM and ID become a
+MD5-hashed access key link (AKEY for regular users, SKEY for subusers,
+GKEY for groupusers), generated by the CGIs, to prevent that a third
+person could easily read these parameters from the user webbrowser URL
+address field. AKEY and SKEY are used as optional cookies, too, for
+extending the session life.
+
+A SKEY is made of md5_hex("$mainuser:$subuser:$subuserid")
+A GKEY is made of md5_hex("$mainuser:$groupname:$groupuser:$groupuserid")
+
+Note: the AKEY, SKEY and GKEY always can be stolen by a network sniffer!
+If you need true security, then you have to use https (SSL) instead of
+http! 
+
+After download the file will be deleted after a grace time of 1 minute.
+This grace time allows a recipient to get the file again if he had
+problems in saving it. 
+
+With the fexsend client the sender can change this behavior:
+
+option -D means "delay autodelete": do not delete the the file directly
+after download, but with the nightly fex_cleanup cronjob. More downloads
+are possible only from the same client (identified by cookie or ip
+address). 
+
+option -K means "keep file": do not delete the file after download, but
+only after expiration date (normally 5 days). More downloads are possible
+only from the same client (identified by cookie or ip address).
+
+
+If you fex a file to yourself (sender = recipient), then the resulting
+download link is valid for any client and can be downloaded everywhere
+and more than once (until expiration date).
+
+If you want "delay autodelete" to be the default behaviour for all users
+and each transfer then set
+	$autodelete = 'DELAY'; # or 'NO' for no autodelete
+in FEXHOME/lib/fex.ph
+
+In addition, you can add to the "Recipient(s)" field of the fup CGI:
+":autodelete=delay" or ":autodelete=no" or ":keep=x" (where x is the number
+of days). Example:
+Recipient(s): framstag@rus.uni-stuttgart.de:keep=10
+
+These options are also possible in the server address book (see CGI fuc).
+
+If you need more security, then set in fex.ph:
+$fop_auth = 'yes';
+$force_https = 'yes';
+
+With $fop_auth upload is restricted to registered users and download
+requires (HTTP) authorization. The credentials are the F*EX user email
+and auth-ID.
+See extra documentation SSL for using https.
+
+If you want to have encrypted emails, then you need a GPG public key for 
+the user fex. Create it with "gpg --gen-key" (use fex@YOURFEXSERVER as the
+user or the $bcc address from fex.ph if you have set it, see below). Next,
+the user has to upload his public key via webinterface "user config &
+operation control" and "Manage e-mail encryption".
+
+"Public upload" is a feature similar to anonymous ftp: the sender does not
+to be registered, but may send only to predefined recipients via
+http://YOURFEXSERVER/pup
+
+The administrator has to define via configuration variable
+@public_recipients the email addresses for which anyone can upload files
+without registration (auth-ID is not necessary). For example:
+
+@public_recipients = qw(fexmaster@YOURDOMAIN bunny@OTHERDOMAIN);
+
+With "anonymous upload" one can use F*EX without registration or
+authentication. The administrator has to define via configuration variable
+@anonymous_upload for which IP addresses this feature is available.
+
+The administrator can globally forbid certain recipient address via fex.ph
+configuration (example):
+
+@forbidden_recipients = qw(nobody@* *@microsoft.com);
+
+The administrator can also forbid a user to fex to any recipient address,
+but the allowed ones with: fac -r USER
+
+
+By standard installation the base directory FEXHOME is the same as the
+login HOME of user fex, but you can move it if you want. FEXHOME is
+determined by the full path of fexsrv as configured in
+/etc/xinetd.d/fex . Change this when you move FEXHOME!
+
+You can also add (name based) virtual hosts with fac.
+
+Do not give write permission to any other user to any file in FEXHOME or
+below!
+
+
+FEXHOME contains:
+
+	spool/				spool directory and user data 
+        htdocs/				directory for generic download files
+        bin/				directory for programs
+        cgi-bin/			directory for CGI programs

+	$to/$from/$file/locale		locale
+
+As you see, the first directory sometimes means sender and sometimes means
+recipient! It depends on the case of usage (up/download).
+
+BEWARE: for the special senders fexmail and anonymous $to and $from are
+swapped (by fup and fop)! This is to prevent overcrowding of the toplevel
+spool directory with _fexmail_$RANDOM and _anonymous_$RANDOM recipients.
+
+
+A registered full F*EX user is identified by the file $spooldir/$from/@
+Only if this file contains his auth-ID this user is able to send files to
+others. Otherwise he is just an unpriviledged recipient.
+
+You can customize the upload CGI fup by editing FEXHOME/lib/fup.pl
+
+Additional directories in spool:
+
+        .dkeys/				download keys lookup directory
+        .ukeys/				upload keys lookup directory
+        .akeys/				authentication keys lookup directory
+        .skeys/				subuser keys lookup directory
+        .gkeys/				groupuser keys lookup directory
+        .xkeys/				extra download keys lookup directory
+        .debug/				directory for debug output (optional)
+        .reg/				temporary data for user selfregistration
+
+The upload keys (UKEY) are necessary to synchronize the file upload by
+HTTP POST with the javascript upload status bar which is an asynchronous
+HTTP GET. The GET process needs to know the corresponding POST process.
+This is done via UKEY, a unique upload identifier.
+
+The download key (DKEY) is a unique identifier for - guess what -
+downloading. It also prevents an attacker to get the file, because only
+the recipient knows the DKEY as part of the download URL from the
+notification email. 
+
+XKEY is an optional extra download key to have a short download URL in
+shape http://YOURFEXSERVER//XKEY
+The XKEY always starts with // and is provided as a COMMENT by the client.
+Example: fexsend schwuppdiwupp.jpg //
+The user has to realize that such URLs have very low security.
+
+If you need to trace a F*EX request, then set 
+	$debug = 1;
+in fex.ph and look in ~/spool/.debug/ for the correspondening files.
+
+The user fex also gets a Bcc of all sent notification emails. This is a
+help for debugging purposes. If you want these Bcc mails to another
+address then set in fex.ph:
+
+	$bcc = 'other@address';
+
+The sender also get a Bcc if he put the string "!bcc!" in the comment
+field.
+
+If you have users within another domain with its own MTA and those users
+want to fex each other, then their MTA probably will reject the
+notification email. To prevent this problem you can set in fex.ph
+@remote_domains = qw(other_domain1 other_domain2 ...);
+In this case "From: $admin" will be used in the notification emails.
+
+F*EX comes with its own web server: fexsrv
+Standard web servers like apache have been proven problematic, either in
+speed or because of a 2-GB-limit. 
+
+It is not possible to use the F*EX CGIs with an alternative web server,
+because the F*EX CGIs need special fexsrv features.
+
+xinetd starts fexsrv for every new connection, which then executes the
+CGIs fup (file upload), fop (file output), fuc (fex user control), foc
+(fex operation control), fac (fex admin control), fur (fex user
+registration) and sex (stream exchange). 
+
+
+SEX has the opposite authorization model of FEX: The sender does not
+need any registration. He can send a stream to any registered SEX user,
+who must identify himself with his auth-ID. This is because a stream does
+not cost resources when it is not bound to a recipient. It will block
+otherwise. The client programs for sexing are sexsend and sexget. You can
+call them also fuckyou and fuckme :-)
+
+
+With the F*EX client fexsend you can have a streaming file transfer with 
+spooling: on client side there is no temporary buffer file (archive), but
+the data is sent directly to the F*EX server. This saves time and disk
+space on the client.
+
+Example for a streaming archive upload:
+
+  fexsend -a music+video.tar *mp3 *avi webmaster@flupp.org
+
+Example for a streaming data upload:
+
+  fpg fex /var/log/* | fexsend -s logs fexmaster@flupp.org
+
+The data streaming is implemented via a HTTP extension: the header
+Content-Length is given -1 which means: unknown length, read until EOF.
+
+For streaming receiving you can use "fexget -s-" or "wget -O-".
+
+
+fexsrv also can do generic document output (via dop) like a normal web
+server. For this, your files must be under FEXHOME/htdocs and they must
+not have the same name as the CGIs under FEXHOME/cgi-bin, because the CGIs
+have priority.
+
+For security reasons, documents to be delivered by dop:
+- the file must be readable by group or world
+- the file must be in FEXHOME/htdocs or a directory specified by @doc_dirs
+- the filename must not start with a "."
+- the filename must not contain a "@"
+- the filename must not end with "~"
+
+To enable HTTP basic authentication, write your access token to a file
+named .htauth which will protect all files in this directory. An user will
+be prompted for this password by his web browser.
+
+To restrict the access to specific client IP addresses, put these IPs into
+a file named .htaccessfrom which will protect all files below this
+directory. You can name single IPs, also as IP ranges (example:
+129.69.0.0-129.69.255.255)
+
+dop is not a regular CGI program (like fup or fop), but a sub-program of
+fexsrv. 
+
+*.html files may contain $VARIABLES$ which will be substituted with the
+value of the corresponding environment variable. See example
+$SERVER_ADMIN$ in FEXHOME/htdocs/index.html
+
+*.html files may contain <> (even multiline) which will be
+evaluated. See example FEXHOME/htdocs/dynamic.html
+This perl-code must not contain '>>' strings itself!
+Pay attention: do not place security relevant data inside << >> because it
+will be delivered to the client if the URL ends with '!'! See example:
+http://fex.rus.uni-stuttgart.de/index.html
+http://fex.rus.uni-stuttgart.de/index.html!
+
+If you want to hide your code, then you have to write a CGI script and
+place it into the cgi-bin directory. Files there will never be delivered
+by dop. You also can do "chmod o-r file.html" to prevent source code
+delivery.
+
+*.html files may contain conditional blocks:
+
+#if (perl-expression)
+   HTML...
+#elseif (perl-expression)
+   HTML...
+#else
+   HTML...
+#endif
+
+which will be evaluated at run-time (#else and #elseif are optional).
+
+*.html files may contain:
+#include "FILE"
+which means: load FILE from current directory at this place in code.
+
+dop also can display a directory listing if this directory contains a file
+named .htindex
+To restrict the listing to specific files, put a matching regular
+expression into .htindex
+Example: echo 'pdf$' > /home/fex/htdocs/doc/.htindex
+
+dop can output gzipped files on-the-fly as a streaming document. For
+example: you have /fex/home/htdocs/big.file but a client requests
+http://YOURFEXSERVER/big.file.gz then a corresponding big.file.gz will be
+delivered.
+
+dop can also output tar, tgz or zip archives on-the-fly as a streaming
+document. Just create a symbolic link with files (or directories) you want
+in this archive and enclose them with ":". The symlink name must end with
+".stream". Example:
+
+http://fex.rus.uni-stuttgart.de:8080/download/sex.tar
+
+fex@fex:~/htdocs/download: ls -l sex*
+lrwxrwxrwx 1 fex fex     7 2011-01-26 11:46 sexget -> sexsend
+-rwxr-xr-x 1 fex fex 12110 2012-08-22 09:55 sexsend
+lrwxrwxrwx 1 fex fex    22 2012-09-01 12:13 sex.stream -> :sexsend:sexget:sexxx:
+lrwxrwxrwx 1 fex fex     7 2012-09-01 11:28 sexxx -> sexsend
+
+It is also possible to create this stream file as a regular file. Then the
+content must be the file names you want in the streaming archive.
+
+Note: you may only use relative paths and without "../" elements.
+
+Note: Files beginning with a . or ending with ~ will not be included in
+the download stream.
+
+cronjob fex_cleanup is run once a day and deletes expired uploads, removes
+inactive accounts and does some other spool houskeeping. See: crontab -l
+
+To detect inactive users you can put in fex.ph:
+$account_expire = "365:notify";
+
+This sends an email to $admin when an user is inactive for 365 days.
+
+Or to delete inactive users you can put in fex.ph:
+$account_expire = "365:delete";
+
+This deletes user accounts automatically which have been inactive for 365
+days. 
+
+Of course you can use any number of days.
+
+Inactive users will get an account reactivation request before.
+
+The address book may contain the optional parameters autodelete and
+keep. Address book example entry:
+
+flupp framstag@flupp.org keep=99 autodelete=no
+
+BUT: these address book parameters are only accepted when using the
+fexsend or schwuppdiwupp client! They will be ignored when using a
+webbrowser!
+
+Nevertheless you may add autodelete and keep parameters using a
+webbrowser, but then they are valid for ALL addresses in the "Recipient"
+field!
+
+The clients fexsend and schwuppdiwupp can MD5-encrypt the auth-ID together
+with a session-ID. The session-ID itself is provided by the server after
+an initial "GET SID" HTTP request. This is not possible through a proxy,
+because most proxies do not support persistant tcp sessions.
+
+See fex-client_2.pdf for the F*EX protocol specification.
+
+To understand and trace the F*EX protocol you can use fexsend with the -v
+option. 
+
+Example (--> means send to server, <-- means receive from server):
+
+framstag@fex:~: fexsend -v X.png framstag@flupp.org

+
+Comment on the HEAD request above:
+The client fexsend sends it to request whether the file has been sent
+before and if it was successful or not. On the later case, the server
+would reply how many bytes has already been received and the client then
+can send only the missing part. Normally the answer to the HEAD request is
+0 (see above), which means: nothing of this file has been received so far.
+
+But this is only half of the truth :-)
+I have omitted in the example above the requests CHECKRECIPIENT and
+GET ADDRESS_BOOK, to keep it simple in the first run.
+CHECKRECIPIENT is a HTTP POST request to check whether the recpient's
+email address is valid to the server.
+GET ADDRESS_BOOK is a HTTP GET request to check if the recipient with a
+short address (= address without @) is an alias in the senders server
+address book. 
+Please use "fexsend -v" by yourself to see the whole protocol dialoge.
+
+Many HTTP proxies have a POST limit, which is often at 2 GB, but sometimes
+lower. To overcome this limitation a F*EX client (like fexsend) may
+include in the POST the HTTP MIME part "filesize" which indicates the full
+file size. All incoming file POSTs with this file name will be appended
+until the full file size is reached. Of course the client has to POST all
+parts of this file, in the correct order, in asking the server how many
+bytes has already been received. Example:
+
+framstag@fex:/tmp: fexsend -vP wwwproxy.uni-stuttgart.de.de:8080:1024 2GB.tmp .

+The default character set for F*EX is UTF-8, because most clients seem to
+use it. The problem is, it is nowhere defined which character set HTTP
+uses itself.
+
+Important for programmers: The perl variables of the F*EX CGI's (fup, fop,
+etc) have their UTF-8 flag turned off. This means, they contain UTF-8 data
+in binary representation.
+
+
+I have additional authentication modules for RADIUS, LDAP, mailman and
+POP. Please email me if you are interested.

+Prerequisites:
+==============
+
+To install the F*EX server, you need a UNIX system with perl, xinetd and
+/usr/lib/sendmail (either original or a clone like postfix or exim). 
+Your perl must have the following standard core modules:
+
+CGI
+CGI::Carp
+Digest::MD5
+Encode
+Fcntl
+File::Basename
+Getopt::Std
+IO::Handle
+POSIX
+
+Optional are the non-standard perl modules:
+
+Net::DNS  		(for better domain error handling)
+Socket6   		(for ipv6 support)
+Net::INET6Glue		(for ipv6 support)
+IO::Socket::INET6	(for ipv6 support)
+
+On Debian or Ubuntu Linux simply execute as root:
+
+  apt-get install xinetd perl-modules libnet-dns-perl libnet-inet6glue-perl
+  test -x /usr/lib/sendmail || apt-get install postfix
+
+Do not forget to open port 80 on your firewalls and routers for incoming
+connections!
+
+To install F*EX, simply run "./install", then edit lib/fex.ph and set your
+local config.  If you want to upgrade from a previous F*EX version, you
+also can run "./install", no old config files will be overwritten. Also
+index.html is kept.
+   
+Alternativly use "./install -p 8888" to install F*EX on port 8888 instead
+on default port 80. 
+
+Run "./install" again for installing optional localizations (languages).
+
+If the install-script does not work for you (no xinetd, no GNU tools, etc)
+here is what is to be done manually for installing:
+
+echo "fex 80/tcp" >> /etc/services
+echo "fex stream tcp nowait fex /home/fex/bin/fexsrv fexsrv" >> /etc/inetd.conf
+# restart inetd or reboot
+useradd -s /bin/bash -c "File EXchange" -m fex
+cd FEXSOURCEDIR
+chown -R fex .
+su - fex
+cd FEXSOURCEDIR
+rsync -av bin cgi-bin lib etc htdocs doc $HOME
+cd $HOME
+mkdir spool
+chmod 700 spool
+vi lib/fex.ph
+# set your config
+crontab -e
+	3 3 * * * exec /home/fex/bin/fex_cleanup
+
+Hints:
+======
+
+F*EX runs with its own uid (default: fex), which will be created by the
+install script.
+
+F*EX uses a directory (FEXHOME) containing anything needed to run fex.
+Default is FEXHOME=/home/fex, the home directory of the "fex" user.
+
+If you want fex to be installed elsewhere create a new "fex" user account
+BEFORE running ./install, e.g.:
+
+adduser --system --group \
+  --gecos "File EXchange" \
+  --home /srv/fex \
+  --shell /bin/bash \
+  fex
+./install
+
+If you run F*EX behind a HTTP reverse proxy, then write to lib/fex.ph :
+	$reverse_proxy_ip = 'internal-IP.address.of.proxy';
+	$durl = 'http://your.proxy.with.domain/fop';
+Be aware that most proxies have a 2 GB file size limit (signed int 32 bit bug)!
+Of course you have to configure your reverse proxy correctly, especially
+the URL rewrite rules. See the manual of your reverse proxy.
+
+If you want to use https, you need the stunnel package. See file SSL for
+more information.
+
+On problems contact the author: framstag@rus.uni-stuttgart.de

+You can prosecute F*EX behind a reverse proxy, but then you are limited to

+  
+  Extract these files? 
+
+
+One problem are shared system accounts like root where different persons
+use them: xx (like fexsend and fexget) uses $HOME/.fex/id which contains
+personal data.
+
+But you can put the ID authorization in the environment variable FEXID.
+
+fexsend on your local account gives you a string for "cut and paste", example: 
+
+  framstag@moep:~: fexsend -I
+  export FEXID='fex.rus.uni-stuttgart.de:8080 framstag jmBhf9ht'
+  history -d $(history 1);history -d $(history 1)
+
+You then copy these two lines with your mouse into the root account:
+
+  root@tandem:~# export FEXID'=fex.rus.uni-stuttgart.de:8080 framstag jmBhf9ht'
+  root@tandem:~# history -d $(history 1);history -d $(history 1)
+
+(The second line deletes these two lines from the bash history)
+
+Now you can use xx (or fexsend and fexget) as normal. Example:
+
+  root@tandem:~# grep sshd /var/log/daemon | xx
+  transfered: 265 kB in 1 s (265 kB/s)
+  
+  framstag@moep:~: xx | wc -l
+  434279
+
+
+After logging out from root@tandem the F*EX authorization data has gone.
+
+
+Internal details:
+
+The intermediate transfer file container is $HOME/.fex/tmp/STDFEX
+
+When transfering files tar/gzip format is used, whereas STDIN (pipe) will
+be transfered uncompressed. Tip: If you want to transfer files uncompress,
+then use: tar cvf - your files... | xx
+
+With default usage only one "storage slot" is available: STDFEX
+But you can use as many "storage slots" as you want by using "xx :TAG" 
+Examples:
+
+  uname -a | xx
+  
+  grep sshd /var/log/daemon | xx :log
+  
+  xx :log | grep obertux  
+  
+  xx :config /boot /etc /root

+Q: I cannot install a web server like fexsrv, because I have no root permissions. Is there a pure-CGI-version of F*EX which runs with an apache web server?
+A: F*EX is hard bound to fexsrv for several reasons (performance, file size limit, session concept, etc) and cannot be run as CGI under apache. But you might have a look at
+
+   * http://gpl.univ-avignon.fr/filez/
+   * http://freshmeat.net/projects/eventh/
+   * http://www.schaarwaechter.de/sp/projekte/dateiaustausch.html (German only!) 
+
+   which implement a file exchange as pure CGIs, but with a 2 GB file size limit, which F*EX does not have.
+
+Q: I have already a webserver (apache) running. How can I install F*EX in parallel?
+A: You have to use a different port or ip for F*EX, because you cannot run two services on the same ip:port combination.
+   For example port 88, use "./install -p 88"
+   For another ip you can create a new virtual interface or use a virtual machine.
+   See the documentation of your UNIX.
+
+Q: Ok, I have installed F*EX. What now?
+A: Become user fex and create some users with fac, example:
+   
+     /home/fex/bin/fac -u memyselfandi@my.do.main secret-auth-id
+   

+   Then log in using the web interface: http://YOURFEXSERVER/
+   
+   ... and join the F*EX mailing list! ☺
+   https://listserv.uni-stuttgart.de/mailman/listinfo/fex
+
+Q: What is /home/fex/bin/fac and /home/fex/cgi-bin/fac ?
+A: fac stands for F*EX Admin Control
+
+   /home/fex/bin/fac is the (full) CLI version
+   
+   /home/fex/cgi-bin/fac is the (restricted) web version. You have to call it with your webbrowser: 
+   http://YOURFEXSERVER/fac
+
+Q: F*EX is not working at all! I cannot connect to it with my web browser!
+A: Check your routing, ipfilters and firewall setup.
+   Also check if xinetd is running. If it is linked with tcp-wrapper, configure it correctly (hosts.allow).
+   F*EX needs port 80/tcp for HTTP and optionally port 443/tcp for HTTPS.
+
+Q: What is the difference between all these user types (full, sub, group, external, ...)?
+A: See http://fex.rus.uni-stuttgart.de/users.html
+
+Q: How can I integrate F*EX in the existing user management at my site?
+A: F*EX has several authentification modules: local, RADIUS, LDAP, mailman and POP.
+   For the last 4 please contact 
+
+Q: Can I make an alias address for an user?
+A: F*EX users are defined by a directory in the spool. Therefore execute:
+
+   
+   cd /home/fex/spool
+   ln -s user@do.main alias@other.address
+   
+   
+   Now the user is known as user@do.main and alias@other.address
+
+Q: I want that all my local users can use F*EX. How?
+A: Let them register themselves with http://YOURFEXSERVER/fur
+
+   You have to edit /home/fex/lib/fex.ph and set (example):
+   
+     @local_hosts = qw(127.0.0.1 10.10.100.0-10.10.255.255);
+     @local_domains = qw(flupp.org ulm.sub.net);
+   

+   Or you can allow anonymous upload for your LAN users with fex.ph variable @anonymous_upload
+   Example:
+   
+     @anonymous_upload = qw(10.10.100.0-10.10.200.255 129.69.1.11);
+   

+   (Of course you have to use your real local hosts/networks!)
+
+Q: I want that external users can fex to my local users. How?
+A: Let them register themselves with http://YOURFEXSERVER/fur
+
+   You have to edit /home/fex/lib/fex.ph and set (example):
+   
+     # your local receiving domains
+     @local_rdomains = qw(flupp.org *.flupp.org);
+     	     
+     # your local receiving hosts
+     @local_rhosts = qw(127.0.0.1 129.69.0.0-129.69.255.255 176.9.84.26);
+   

+   
+   Or you can manually create a restricted external user with (example):
+   
+     /home/fex/bin/fac -u framstag@rus.uni-stuttgart.de hoppla
+     /home/fex/bin/fac -R framstag@rus.uni-stuttgart.de
+   

+
+Q: How can I change user settings like quota, restrictions or keep time?
+A: Use /home/fex/bin/fac
+
+Q: How can I delete or temporarly disable a user?
+A: Use /home/fex/bin/fac
+
+Q: I have BIG files already on the fexserver host. Can I upload just a
+   link instead of the whole file?
+A: Set in fex.ph:
+
+   
+   @file_link_dirs = qw(/directory/with/big/files);
+   
+   

+   and use:
+   

+   
+   fexsend -/ /directory/with/big/files/BIG.file recipient@wherever
+   
+
+Q: I want the Bcc mails to fex (admin user) to be sent to another address.
+A: Set variable $bcc in /home/fex/lib/fex.ph
+
+Q: I need more security! How can I enable (https) encryption?
+A: Read doc/SSL and also look for "fop_auth" in doc/concept 
+   (doc is a local directory in your installation or online http://fex.rus.uni-stuttgart.de/doc/)
+   For email encryption see http://fex.rus.uni-stuttgart.de/gpg.html
+
+Q: I need a corporate identity look. How can I configure F*EX in this way?
+A: * See variable @H1_extra in /home/fex/lib/fex.ph and you can add HTML code to /home/fex/htdocs/header.html
+   * See /home/fex/htdocs/fup_template.html, modify it to your needs and use it as your start-page.
+   * Contact  http://www.nepustil.net/ if you need more customization.
+
+Q: F*EX is too complicated for my tie users. I need a simplified upload form.
+A: See /home/fex/htdocs/fup_template.html and /home/fex/htdocs/sup.html 
+   or use public upload, see http://fex.rus.uni-stuttgart.de/usecases/foreign.html
+
+Q: F*EX is still too complicated! I need something more simplified.
+A: Try http://fex.rus.uni-stuttgart.de/fstools/woos.html or use F*EX mail (see next question).
+
+Q: Can I integrate F*EX in my users MUAs (thunderbird, outlook, etc)?
+A: See http://fex.rus.uni-stuttgart.de/usecases/BIGMAIL.html
+
+Q: Can I get a localized version in my native languange?
+A: With your help, yes. Please contact 
+
+Q: I need ACLs for group access, a file browser and integration in my
+   native file system.
+A: This is beyond the scope of F*EX, which is designed for efficient file transfer only.
+
+Q: Feature/design XY is missing.
+A: Contact the author 
+
+Q: How can I get fup as start page?
+A: Execute:
+
+   
+   cd /home/fex/cgi-bin
+   ln -s fup login
+   
+
+Q: How can I use my own local FAQ?
+A: Put your FAQ into file /home/fex/htdocs/FAQ/local.faq and execute:
+
+   
+   cd /home/fex/htdocs/FAQ
+   ln -sf local.html index.html

+Q: What is so special about F*EX?
+A: See feature list http://fex.rus.uni-stuttgart.de/features.html
+   and use cases http://fex.rus.uni-stuttgart.de/usecases/
+
+Q: Why not use one of the commercial services like DropLoad, ALLPeers, YouSendIt, etc?
+A: * They have a file size limit of 2 GB or even less.
+   * Their security and privacy status is unknown (ever heard of "Snowden & NSA"?).
+   * They are not open source based.
+   * There are no UNIX (CLI) clients for them.
+   * They need java, active-X, flash or other evil plugins.
+   * It is unknown how long they will exist - DropLoad and ALLPeers already have terminated their business.
+   
+Q: Why name "F*EX" and not shortly "FEX"?
+A: At publication time there was already an (older) program named "FEX" listed on freshmeat.net.
+
+Q: Who is the author?
+A: The main author is Ulli Horlacher 

+   But there are also a lot of contributors.
+
+Q: Why a camel as the logo?
+A: The logo was inspired by the Perl camel, but it is based on a Steiff plush camel, which rides with us on our racing tandem.
+   The logo was drawn by my stoker Beate.
+   http://fex.rus.uni-stuttgart.de/Vortrag/tosa.html
+
+Q: What do I need to install F*EX?
+A: A UNIX or Windows server with a DNS entry, smtp for outgoing email and one open and free incoming tcp port.
+   You must have administrative rights (UNIX: root) on this server and a basic understanding of UNIX and networking.
+
+Q: What means DNS and smtp? What is a tcp port?
+A: Do not install F*EX. It is beyond your horizon.
+
+Q: Does F*EX support IPv6?
+A: Yes.
+
+Q: Can I run F*EX on Windows?
+A: On client side all operating systems are supported, even Windows.
+   If you want to run a F*EX server on Windows, then see http://fex.rus.uni-stuttgart.de/fexwix.html
+
+Q: Where can I get the F*EX sources?
+A: F*EX server for UNIX: http://fex.rus.uni-stuttgart.de/fex.html
+
+Q: I do not want to install a F*EX server of my own, but where can I use it?
+A: Contact  http://www.nepustil.net/ for F*EX hosting.
+
+Q: The F*EX server is all in Perl?! Isn't Perl too slow for this job?
+A: fex.rus.uni-stuttgart.de runs on an office PC and F*EX is able to handle uploads with more than 300 MB/s.
+   Try this with an ordinary webserver like Apache!
+
+Q: Which licence does F*EX have? And why?
+A: Perl Artistic free software with a special anti-military clause: 
+   http://fex.rus.uni-stuttgart.de/doc/Licence
+   "I want peace on earth and goodwill towards men"
+   http://www.youtube.com/watch?v=JHU0HinVhYc
+
+Q: Is there a F*EX mailing list?
+A: https://listserv.uni-stuttgart.de/mailman/listinfo/fex
+
+Q: Where can I get commercial support for F*EX?
+A: Contact  http://www.nepustil.net/
+
+Q: Who else is using F*EX?
+A: For example:
+   * German Aerospace Center http://fex.dlr.de
+   * European Commission Institute for Energy and Transport http://fex.jrc.nl
+   * High Performance Computing Center Stuttgart http://fex.hlrs.de
+   * Swiss National Supercomputing Centre http://fex.cscs.ch
+   * Centre National de la Recherche Scientifique (French National Center for Scientific Research) http://bigfiles.cnrs-gif.fr
+   * Institut Pasteur http://dl.pasteur.fr
+   * Palo Alto Research Center (Xerox PARC) http://parcftp.parc.com
+   * Baden-Württembergs extended LAN http://fex.belwue.de
+   * Deutsche Kinemathek Museum für Film und Fernsehen http://upload.deutsche-kinemathek.de
+
+Q: Is F*EX secure?
+A: F*EX is written in Perl which does not have common security problems with buffer overruns, segmentation faults, heap and stack corruption.
+   F*EX does not use an extra web server or a (SQL) database, so no typical web attacks are possible.
+   F*EX was analysed by security company revshell.com and labeled as "secure".
+   F*EX comes with source code, so everybody can verify it.
+   
+Q: Feature/design XY is missing.
+A: Contact the author 
+
+Q: I have more/other questions than in this document!

+Q: What is the "auth-ID"?
+A: The auth-ID is an internal identification which authentificates the user. It will be first generated by the admin or the automatic registration process and can later be modified by you, the user. Think of some kind of a low security password.
+
+Q: What is the difference between all these user types (full, sub, group, external, ...)?
+A: See http://fex.rus.uni-stuttgart.de/users.html
+
+Q: I have uploaded a HUGE file but misspelled my recipient's address. Now I have got an error bounce email. Must I re-upload the HUGE file?
+A: No, it is not necessary. You can redirect the file with "user config & operation control"
+
+Q: I have uploaded a HUGE file but forgot another recipient. Must I re-upload the HUGE file?
+A: No, it is not necessary. You can forward-copy the file with "user config & operation control"
+
+Q: Can I use an HTTP proxy?
+A: Yes, but pay attention:
+   Some HTTP proxies like privoxy delay the upload progress bar!
+   You may want to disable proxying $SERVER_NAME$ if you run into this problem.
+
+Q: My recipient has lost the notification email with the download-URL. What can I do?
+A: You can resend the notification email via "user config & operation control"
+
+Q: Why should I use a special F*EX client?
+A: When you are using F*EX with your webbrowser, you are limited to its restrictions.
+   With a special F*EX client http://$HTTP_HOST$/tools.html you can
+
+   * resume an aborted transfer
+   * send several files or even whole directory trees at once
+   * stream files
+   * transfer files via command line
+   * use an Internet clipboard http://fex.rus.uni-stuttgart.de/usecases/xx.html
+   * do much more :-)
+
+Q: How can I upload several files at once?
+A: Put your files in an archive file (ZIP). Your web browser cannot do that.
+   Or you can use a F*EX client, see http://$HTTP_HOST$/tools.html
+
+Q: I cannot upload files > 2 GB with my web browser!?
+A: Many web browsers have bugs in their HTML-FORM implementation. The limit mostly is 2 GB, sometimes 4 GB.
+   Firefox and Google Chrome have no limitation.
+   But remember: No web browser is able to resume an interrupted upload. You need a special F*EX client like fexsend or schwuppdiwupp for resuming, see http://$HTTP_HOST$/tools.html
+
+Q: I need to send a file bigger than my quota allows. What can I do?
+A: Simply ask $SERVER_ADMIN$ to raise your quota.
+
+Q: Why is the upload status window empty and I cannot see the progress bar?
+A: Most probably you are using a (enforced) web proxy, which cannot handle dynamic HTML pages.
+   A workaround is using Google Chrome, which shows the upload status by itself.
+
+Q: My download was aborted before it was finished. Can I resume the download?
+A: F*EX supports resuming at download, but your client also has to support this feature.
+   Firefox e.g. is missing this HTTP feature, you need an other client like opera, wget or fexget.
+
+Q: My upload was aborted before it was finished. Can I resume the upload?
+A: F*EX supports resuming at upload, but your client also has to support it.
+   No web browser has this feature, you need a special F*EX client like fexsend or schwuppdiwupp,
+   see http://$HTTP_HOST$/tools.html
+
+Q: Can I integrate F*EX in my mail program (thunderbird, outlook, etc)?
+A: Yes, if your mail admin has set up a "fexmail" smtp relay.
+   http://fex.rus.uni-stuttgart.de/usecases/BIGMAIL.html
+
+Q: Can I use a download manager/accelerator?
+A: Generally, no, because they suck: they are not RFC compliant and produce a LOT of unnecessary server load.
+   But there is one exception: axel http://axel.alioth.debian.org/
+
+Q: When I hit [ESC] in firefox the upload is canceled. Why?
+A: This is a built-in feature of firefox: ESC terminates the current operation.
+   Simple solution: do not hit ESC in Firefox.
+   Complex solution: ask the Firefox developers to add keyboard configuration.
+
+Q: Sending as a F*EX user is easy, but how to receive files from others, outside?
+A: Register them as your subusers, create a F*EX group or a one-time upload key with "user config & operation control"
+   See also http://fex.rus.uni-stuttgart.de/usecases/foreign.html
+
+Q: Sometimes I can download a file more than once, especially when I repeat it quickly. Is the autodelete feature buggy?
+A: The F*EX server has a grace time of 1 minute after first sucessfully download in which the file is still available. This is necessary because of some stupid "download managers" which request the file several times at once. Otherwise they would report an error to the user.
+
+   Your fexmaster has set AUTODELETE=DELAY as default, which means that the autodelete cleanup process is called once a day.
+   
+   Power users (use the source, Luke!) can set a "do not delete after download" flag.
+
+Q: I have uploaded a file to a list of recipients. Will the file be deleted after the first recipient has dowloaded it?
+A: No. Every recipient gets his own copy of the file which is independant from the others.
+
+Q: The default keep time is too short for me (sender), I need more. How can I set it?
+A: Use fexsend, ask $SERVER_ADMIN$ or read the source code :-)
+
+Q: The default keep time is too short for me (recipient), I need more. How can I set it?
+A: Ask $SERVER_ADMIN$ to raise your default KEEP value.
+
+Q: I forgot to download a file. Now it is expired. How can I obtain it nevertheless?
+A: An expired file is definitively deleted. Even the admin cannot restore it.
+   You must re-request it from the sender.
+
+Q: I have sent a second file with the same name, but the recpient has not received a second notification email. Why?
+A: A file with the same name to the same recpient overwrites the first one if it is still there (no download so far).
+   A second notification email of the same file(name) is not suggestive.
+
+Q: How can I sent a more compact notification email?
+A: Let your comment start with "!.!", then the notification email will contain only download-URL, size and comment.
+
+Q: How can I suppress the automatic notification email?
+A: Use "!#!" as comment, then no notification email will be sent.
+   Of course you then have to inform the recipient manually.
+
+Q: Can I get a copy of the notification email?
+A: Add "!bcc!" to the comment field on upload.
+
+Q: Can I get a notification email on download?
+A: No.
+   Such a feature is in conflict with German and European privacy laws and will not be implemented.
+   With email you also have no acknowledgement of receipt.
+
+Q: Can I have encrypted emails?
+A: See http://fex.rus.uni-stuttgart.de/gpg.html
+
+Q: I cannot download files with Internet Explorer, it tells me "Cannot open Internet site". What shall I do?
+A: Use Firefox or any other Internet-compatible web browser, that Internet Explorer is not.
+   This is one of the many bugs of Internet Explorer.
+   See also http://support.microsoft.com/kb/323308
+
+Q: I cannot login with Internet Explorer, it tells me "This page can't be displayed". What shall I do?
+A: Use Firefox or any other Internet-compatible web browser, that Internet Explorer is not.
+   This is one of the many bugs of Internet Explorer.
+
+Q: I have recived a "file.7z". How can I extract it on my Mac?
+A: For example with "Stuffit Expander":
+   https://itunes.apple.com/us/app/stuffit-expander/id405580712?mt=12
+   http://my.smithmicro.com/stuffit-expander-mac-download.html
+
+Q: How can I prevent the fexsend error SSL3_GET_SERVER_CERTIFICATE:certificate verify failed?
+A: Set the environment variable SSLVERIFY=0
+
+   Rationale: 
+   Your openssl library cannot resolve the SSL certification path. 
+   With SSLVERIFY=0 you tell openssl to ignore certification verification.
+   Yes, this is a crude workaround :-}

+
+8. Aggregation of this Package with a commercial distribution is always
+   permitted provided that the use of this Package is embedded; that is,

+Stream EXchange
+

+
Stream EXchange (SEX)

+
+You can imagine SEX as network wide UNIX pipes with a relay between or as
+network based FIFOs.

+This can be useful for piping data from A to B where
+A and B cannot establish a direct connection, but both can connect to the
+SEX-server by HTTP.

+SEX is a synchronous service in conjuction to F*EX
+which is asynchronous.
+

+For seamless integration into the UNIX tool chain, there are the
+shell-tools sexsend and sexget.
+

+Using web browsers for sexing will not work, because they cannot handle
+streams in a pipe. So far, there are only the UNIX clients. Feel free to
+implement other clients for other operating systems :-)
+

+Authentication is the same as with F*EX.
+

+Example:
+

+
+  root@lanldap:/var/log: tail -f syslog | sexsend framstag@rus.uni-stuttgart.de
+
+  framstag@blubb:/tmp: sexget | grep ldap
+

+

+If you need encryption, then use the standard UNIX toolbox and add an
+appropriate program to the pipe, for example: openssl bf
+
+
public SEX

+The recipient of regular SEX must be a registered F*EX user.

+But you can also offer streams to non-registered user.

+This is called "public SEX", example:
+

+
+  framstag@flupp: cal | sexsend public
+  http://fex.rus.uni-stuttgart.de/sex?user=framstag@rus.uni-stuttgart.de&ID=public
+  http://fex.rus.uni-stuttgart.de/sex?dXNlcj1mcmFtc3RhZ0BydXMudW5pLXN0dXR0Z2FydC5kZSZJRD1wdWJsaWM=
+

+

+sexsend then displays two URLs onder which one can get the stream.
+
+
SEX - all inclusive

+To transfer files by streaming you can use xx-rated SEX:
+

+
+  root@vms2:/data/VM# sexxx flupp
+  streaming:
+  flupp/
+  flupp/vmware.log
+  flupp/flupp.nvram
+  flupp/flupp.vmxf
+  flupp/flupp.vmx
+  flupp/flupp.vmdk

+F*EX - File EXchange
+
+

+
F*EX - Frams' Fast File EXchange

+
+

+

+F*EX (Frams' Fast File EXchange) is a service to send big (large, huge,
+giant, ...) files from a user A to a user B.
+

+The sender uploads the file to the F*EX server using a 
+WWW upload form and the recipient
+automatically gets a notification e-mail with a download-URL. 
+

+
+You say:
+

+  Why do I need another service for file transfer?!

+  I have e-mail, ftp, ssh and even sendfile!
+

+

+I say:
+

+  You still need F*EX :-)
+

+

+  
+For example, you want to send your friend your last holiday video (1 GB).
+You have the following possibilities (and problems):

+
+
    
+  
  • sending a DVD by postal service
    
+      Out of the question - we live in the year 
+      <> 
+      after invention of the internet!
+      Sending media (hardware) is for grandpas.
+      
    
+  
  • using e-mail
    
+      Most e-mail servers have a limit of 10 MB per e-mail and a
+      storage-quota of a few 100 MB per user or even less.
+      
    
+  
  • uucp
    
+      Why not cuneiform writing on stone plates?
+      
    
+  
  • ssh
    
+      You have your friends password or you are willing to give him yours
+      - just for a file transfer?
+      
    
+  
  • ftp
    
+      
      
+        
    • Using which ftp server?
+        
    • Using which account, which password?
+        
    • You do not mind sending unencrypted passwords and files over the insecure internet?
+        
    • Your proxy supports passive-ftp?
+        
    • In case of anonymous ftp:
+          
        
+            
      • Does it allow 1 GB uploads?
+            
      • Does it allow to delete the upload afterwards?
+            
      • Who else can download your file?
+            
      • Who else can delete your file?
+            
      • You have to send your friend the download-URL, he has to
+                inform you about the successful download, you have to delete 
+                it afterwards.
        
+                All in all: a pain in the ass.
+          
      
+      
    
+      
    
+  
  • http
    
+      
      
+        
    • No default upload and user management - must be programmed
+        
    • No auto-notification
+        
    • No auto-deletion
+        
    • Very few http servers can handle files greater than 2 GB
+      
    
+      
    
+  
  • 
+          sendfile
    
+      
      
+        
    • You run UNIX and have sendfile installed?
+        
    • Your recipient runs UNIX and has sendfile installed?
+        
    • Neither you nor your recipient has a firewall blocking port 487?
+      
    
+      
    
+  
  • commercial services like DropLoad, ALLPeers, YouSendIt, etc
    
+      
      
+        
    • What limit do they have (most: < 2 GB)?
+        
    • What about security and privacy: will your files be save and secure?
+        
    • Are they open source based or closed proprietary?
+        
    • Are they accessible with any browser or do you need java, active-X, flash or other evil plugins?
+        
    • Will they exist longer than a few months?
      
+           (DropLoad, ALLPeers and drop.io already have terminated their business)
+      
    
+      
    
+

+

+If you have answered only once "no" to the questions above, then you need
+F*EX.
+

+
Main features of F*EX

+

+
    
+  
  • file transfer of virtually unlimited file size
+  
  • recipient and sender only need an e-mail program and a web browser -
+      of any kind, they do not have to install any software
+  
  • RESEND and REGET for resuming after link failures at last sent byte
+  
  • auto-notification of recipient
+  
  • auto-deletion after download
+  
  • auto-deletion after expiration date (default: <<$keep>> days)
+  
  • full-users can create one time upload URLs for foreign users
+  
  • full-users can create sub-users, who can send only to this full-user
+  
  • full-users can create groups, an analogy to mailing lists, but for files
+  
  • maintenance-free: no admin interaction necessary besides creating new F*EX accounts
+  
  • Sending to multiple recipients needs storage on the server only once
+  
  • F*EX is a HTTP web-service and needs no firewall-tunnels
+  
  • support for streams, too
+  
  • for real UNIX users, there are the shell programs fexsend and fexget to
+      avoid annoying web browser usage
+  
  • protocol and source-code free available
+

+
+
Let's talk about SEX

+F*EX has a companion: Stream EXchange (SEX).

+You can imagine SEX as network wide UNIX pipes with a relay between.
+This can be useful for piping data from user A to user B where A and B cannot
+establish a direct connection, but both can connect by HTTP to the
+SEX server. For seamless integration into the UNIX tool chain, there are
+the shell-tools sexsend and sexget.
+

+Authentication is the same as with F*EX.
+
+
Still questions?

+See the FAQ
+and the use cases.

+

+NOTE: Many web browsers cannot upload files > 2 GB!

+If your file is larger you have to use a special F*EX client
+or Firefox or Google Chrome which have no size limit.

+You also need a F*EX client for resuming interrupted uploads. Your web browser cannot do this.

F*EX - Frams' Fast File EXchange

+
+

+

+F*EX (Frams' Fast File EXchange) je služba pro odesílání velkých 
+souborů uživatelem A uživateli B.
+

+Odesilatel pomocí webového formuláře pro nahrání nahraje 
+soubor na F*EX server a ten příjemci automaticky odešle 
+e-mail s oznámením a s URL ke stažení.
+

+
+Říkáte si:
+

+  Proč potřebuji další službu pro přenos souborů?!

+  Mám e-mail, ftp, ssh a v neposlední řadě i sendfile!
+

+

+Já pravím:
+

+  Stále potřebujete F*EX :-)
+

+

+  
+Například chcete poslat svému známému video z vaší poslední dovolené (1 GB).
+Máte následující možnosti (a s tím související problémy):

+
+
    
+  
  • poslat DVD poÅ¡tou
    
+      Nepřichází v úvahu - žijeme 
+      <> let
+      od roku, kdy byl vynalezen Internet!
+      Posílání paměťových médií je pro staříky.
+      
    
+  
  • použít e-mail
    
+      Většina e-mailových serverů má limit pro přílohu 10 MB a
+      velikost schránky kolem 100 MB a někdy i méně.
+      
    
+  
  • uucp
    
+      Proč rovnou nezůstat u psaní klínovým písmem na kamenné destičky?
+      
    
+  
  • ssh
    
+      Vy máte heslo svého známého, nebo se mu chystáte dát to své
+      jen kvůli přenosu souboru?
+      
    
+  
  • ftp
    
+      
      
+        
    • Pomocí jakého ftp serveru?
+        
    • Pomocí jakého účtu, jakého hesla?
+        
    • Vám nevadí posílání neÅ¡ifrovaného hesla a souborů přes nezabezpečený Internet?
+        
    • Podporuje vaÅ¡e proxy pasivní režim pro ftp?
+        
    • V případě anonymního ftp:
+          
        
+            
      • Umožňuje nahrát 1 GB?
+            
      • Umožňuje po nahrání soubor smazat?
+            
      • Kdo další si váš soubor může stáhnout?
+            
      • Kdo další může váš soubor smazat?
+            
      • Svému známému musíte poslat URL, kde si soubor může stáhnout, on vás musí
+                informovat, že si soubor stáhl, vy jej pak 
+                musíte smazat.
        
+                Sečteno a podrženo: Otrava.
+          
      
+      
    
+      
    
+  
  • http
    
+      
      
+        
    • Žádné výchozí nahrávání a správa uživatelů - musí se naprogramovat
+        
    • Žádné automatické oznamování
+        
    • Žádné automatické mazání
+        
    • Velice málo http serverů umí zpracovat soubory větší než 2 GB
+      
    
+      
    
+  
  • sendfile
    
+      
      
+        
    • Používáte UNIX a máte nainstalovaný sendfile?
+        
    • Používá příjemce UNIX a má nainstalovaný sendfile?
+        
    • Nemáte vy ani příjemce firewall, který blokuje port 487?
+      
    
+      
    
+  
  • komerční služby jako jsou DropLoad, ALLPeers, YouSendIt, etd.
    
+      
      
+        
    • Jaký mají limit (větÅ¡inou méně než 2 GB)?
+        
    • Co bezpečnost a ochrana osobních údajů: Budou vaÅ¡e soubory skutečně uloženy a v bezpečí?
+        
    • Jsou provozovány na open-source, nebo na uzavřeném proprietálním softwaru?
+        
    • Jsou přístupné se vÅ¡emi prohlížeči, nebo potřebujete Javu, Active-X, Flash či jiné hnusné zásuvné moduly?
+        
    • Budou existovat více, jak pár měsíců?
      
+           (DropLoad, ALLPeers a drop.io své služby již ukončili)
+      
    
+      
    
+

+

+Pokud jste byť na jedinou z výše uvedených otázek odpověděli "ne", potom potřebujete 
+F*EX.
+

+
Hlavní funkce F*EX

+

+
    
+  
  • přenos souborů s prakticky neomezenou velikostí
+  
  • příjemci a uživatelé potřebují pouze program pro elektronickou poÅ¡tu a webový prohlížeč
+      jakéhokoli typu, nemusí instalovat žádný další software
+  
  • ZNOVU ODESLÁNÍ a ZNOVU STAŽENÍ pro pokračování přesně tam, kde doÅ¡lo k selhání spojení
+  
  • automatické oznamování pro příjemce
+  
  • automatické mazání po stažení
+  
  • automatické mazání po době platnosti (výchozí: 5 dnů)
+  
  • plnohodnotní uživatelé si mohou vytvářet poduživatelé, kteří mohou odesílat pouze jim
+  
  • plnohodnotní uživatelé mohou vytvářet skupiny, obdoba poÅ¡tovních konferencí s tím rozdílem, že se jedná o soubory
+  
  • bezúdržbovost: ze strany správce nejsou nutné žádné zásahy s vyjímkou vytváření nových F*EX účtů
+  
  • odesílání více příjemcům spotřebuje na serveru pouze místo pro jednoho příjemce
+  
  • F*EX je webová služba pro protokol HTTP a nepotřebuje žádné tunely ve firewallu
+  
  • podporuje také vysílání
+  
  • pro skalní UNIXové uživatele jsou k dispozici programy pro příkazovou řádku fexsend a fexget pro
+      vyhnutí se použití otravných webových prohlížečů
+  
  • protokol i zdrojový kód jsou volně dostupné (Perl Artistic)
+

+
+
Promluvme si o SEXu

+F*EX má společníka: Stream EXchange (SEX).

+SEX si můžete představit jako bránu mezi UNIXovými síťovými rourami.
+Ta může být užitečná k odesílání dat uživatelem A uživateli B, kde A a B mezi sebou
+nemohou navázat přímé spojení, ale oba dva se mohou připojit pomocí HTTP k 
+SEX serveru. Pro snadné začlenění do řady UNIXových nástrojů slouží nástroje
+pro příkazovou řádku sexsend a sexget.
+

+Ověřování je stejné jako u F*EX.

+
+$info_2 = <

+Po potrzení uvidíte lištu s průběhem nahrávání 
+(pouze, pokud máte povolen javascript a povolené automatické otevírání oken).
+

+POZNÁMKA: Většina webových prohlížečů neumožňuje nahrávat soubory větší než 2 GB!

+Pokud je váš soubor větší, použíjte speciálního klienta pro F*EX.

+Potřebuvoat budete také klient pro obnovení nahrávání v případě přerušení. Váš webový prohlížeč toto neumožňuje.
+

+UPOZORNĚNÍ: Některé HTTP proxy servery, jako je třeba privoxy, spomalují průběh nahrávání!

+V případě, že se s tímto pborlémem setkáte, bude zřejmě třeba zakázat používání proxy pro $ENV{SERVER_NAME}.
+

+Pro uživatele Firefoxu: Nemačkejte klávesu ESC, protože jinak se stahování přeruší!

+
+Q: Je ne peux pas installer un serveur web comme fexsrv parce que je n'ai pas les permissions root. Est-ce qu'il existe une version pure CGI de F*EX qui puisse tourner avec un server Apache ?
+A: F*EX est fortement lié à fexsrv pour plusieurs raisons (performance, limite de la taille des fichiers, session, etc...) et ne peut pas tourner comme un CGI sous Apache. Mais vous pouvez jeter un oeil à 
+
    
+
  • http://gpl.univ-avignon.fr/filez/
+
  • http://freshmeat.net/projects/eventh/
+
  • http://www.schaarwaechter.de/sp/projekte/dateiaustausch.html (en Allemand) 
+

+qui implementent le transfert de fichier avec des CGIs pures, mais avec une limite de 2GB.
+
+Q: F*EX ne fonctionne pas du tout ! Je ne peux pas m'y connecter avec mon navigateur web !
+A: Vérifier votre routage, ipfilters et la configuration de votre pare-feux.
+   Vérifier également si votre xinetd est linké à tcp-wrapper et configuré convenablement (hosts.allow).
+   F*EX a besoin du port 80/tcp pour HTTP et optionnellement du port 443/tcp pour HTTPS.
+
+Q: F*EX est trop complexe ! J'ai besoin de quelque chose encore plus simple.
+A: Essayez http://www.home.unix-ag.org/simon/woof.html
+
+Q: Comment puis-je intégrer F*EX à un système d'annuaire ou de gestion d'identité ?
+A: F*EX a plusieurs modules d'authentification: local, RADIUS, LDAP, mailman et POP.
+   Pour les quatre derniers, contacter framstag@rus.uni-stuttgart.de
+
+Q: Je veux que tous mes utilisateurs locaux puissent utiliser F*EX. Comment je fais ?
+A: Ils doivent s'enregistrer eux-mêmes avec http://$HTTP_HOST$/fur

+   Il faut éditer lib/fex.ph et configurer (exemple):
+
+ @local_hosts = qw(127.0.0.1 10.10.100.0-10.10.255.255);
+ @local_domains = qw(flupp.org ulm.sub.net);
+

+(Bien entendu, vous devez utiliser les paramètres propres à votre réseau !)
+
+Q: J'ai besoin de plus de sécurité ! Comment activer HTTPS ?
+A: Lisez doc/SSL and jetez un oeil à "fop_auth" dans doc/concept
+
+Q: J'ai besoin d'un look adapté à mon image. Comment puis-je configurer F*EX en ce sens ?
+A: Voir la variable @H1_extra dans fex.ph et aussi l'ajout possible de code HTML à htdocs/header.html

+   Voir htdocs/fup_template.html, le modifier selon vos besoins et l'utiliser comme page de démarrage.
+
+Q: F*EX est trop compliqué pour mes utilisateurs. J'ai besoin d'un formulaire d'upload simplifié.
+A: Voir htdocs/fup_template.html
+
+Q: Je veux que les mails Bcc destinés à F*EX (utilisateur admin) soient envoyés à une autre adresse.
+A: Positionnez la variable $bcc dans fex.ph
+
+Q: Puis-je avoir une version localisé dans ma langue ?
+A: Avec votre aide, oui. Merci de contacter framstag@rus.uni-stuttgart.de

+
+
+Q: Pourquoi "F*EX" comme nom et pas simplement "FEX"
+A: À l'époque de l'annonce du logiciel, il existait déja un programme (plus ancien) nommé "FEX" sur 
+   freshmeat.net.
+
+Q: Pourquoi ne pas utiliser un service commercial comme DropLoad, ALLPeers, YouSendIt, etc ?
+A: 
    
+   
  • Ils ont une limite de 2GB ou moins.
+   
  • Leur politique de sécurité et de confidentialité est inconnue.
+   
  • Ils ne sont pas opensource.
+   
  • Il n'y a pas d'interface en ligne de commande (CLI) UNIX.
+   
  • Ils ont besoin de java, active-X, flash ou d'autres plugins esotériques.
+   
  • On ne sait pas combien de temps ils vont exister - DropLoad and ALLPeers ont déja cessé leur activité.
+   

+   
+Q: Pourquoi un chameau comme logo ?
+A: Le logo est inspiré du chameau de Perl, mais il est basé sur un chameau "Steiff plush"
+   qui courent avec nous lors de nos courses de tandem. Le logo a été dessiné par mon "chauffeur" Beate.
+   http://fex.rus.uni-stuttgart.de/Vortrag/tosa.html
+
+Q: Où puis-je récupérer les sources de F*EX ?
+A: http://fex.rus.uni-stuttgart.de/fex.html
+
+Q: Perl n'est-il pas trop lent pour faire tout ça ?
+A: fex.rus.uni-stuttgart.de tourne sur un ordinateur de bureau et est capable de gérer des uploads
+   à plus de 300 MB/s. Essayer donc ça avec un serveur web généraliste comme Apache !
+
+Q: De quoi ais-je besoin de pour installer F*EX ?
+A: D'une machine UNIX avec une entrée DNS et un service smtp fonctionnel. Vous devez être root sur la machine.
+
+Q: Qu'est-ce que DNS et smtp ?
+A: N'installez pas F*EX. Ce n'est pas fait pour vous.
+
+Q: Qui est l'auteur ?
+A: Ulli Horlacher framstag@rus.uni-stuttgart.de
+
+Q: Quel est la licence de F*EX ?
+A: Perl Artistic free software
+
+Q: Est-ce qu'il y a une mailing list F*EX ?
+A: https://listserv.uni-stuttgart.de/mailman/listinfo/fex
+
+Q: Où puis-je avoir un support commercial pour F*EX ?
+A: Contacter fex@nepustil.net http://www.nepustil.net/
+
+Q: J'ai encore des questions !
+A: Demandez directement à l'auteur framstag@rus.uni-stuttgart.de

+
+
+Q: Qu'est-ce que l'auth-ID ?
+A: L'auth-ID est un moyen d'authentification interne qui permet d'authentifier l'utilisateur. Il sera d'abord généré par l'admin ou le processus d'enregistrement automatique et pourra être modifié plus tard par vous, l'utilisateur. Vous pouvez y penser comme à un mot de passe à faible sécurité.
+
+Q: Puis-je utiliser un proxy HTTP ?
+A: Oui, mais attention:
+   Certain proxy http comme HTTP introduise un délai dans l'affichage de la barre de progression lors d'un upload !
+   Vous pouvez essayer de désactiver le proxy pour $SERVER_NAME si vous rencontrez ce problème.
+
+Q: J'ai uploadé un fichier très volumineux mais j'ai fait une faute dans l'adresse du destinataire. J'ai reçu un message d'erreur par mail. Dois-je uploader à nouveau ce fichier ?
+A: Non, cela n'est pas nécessaire. Vous pouvez rediriger un fichier via le menu "Configuration utilisateur & Gestion"
+
+Q: Mon destinataire a perdu son e-mail de notification avec l'URL de téléchargement. Que puis-je faire ?
+A: Vous pouvez vous faire suivre une nouvelle copie du fichier via le menu "Configuration utilisateur & Gestion".
+   Vous recevrez un nouveau message de notification que vous pourrez envoyer à votre destinataire par la poste ou un fax :-)
+
+Q: Je ne peux pas uploader de fichiers > 2 GB avec mon navigateur internet !?
+A: Tous les navigateurs web que je connais ont des bugs dans leur implémentation de HTML-FORM. La plupart du temps, la limite est de 2 GB, parfois 4 GB.
+   Vous devez utiliser un client F*EX spécial pour uploader des fichiers > 2 GB, voir http://$HTTP_HOST$/tools.html
+   Firefox 7 (et suivant) est une exception : F*EX contourne des failles dans l'implémentation de l'upload afin de pouvoir uploader des fichiers de n'importe quelle taille.
+
+Q: Mon téléchargement a été interrompu avant la fin. Puis-je reprendre le téléchargement là où il s'est arrêté ?
+A: F*EX support la reprise de téléchargement, mais votre client doit aussi le supporter.
+   Firefox ne possède pas cette capacité HTTP, vous devez utiliser une autre client comme opera, wget ou fexget.
+
+Q: Mon upload a été interrompu avant la fin. Puis-je reprendre l'upload là où il s'est arrêté ?
+A: F*EX supporte la reprise d'upload, mais votre client doit aussi le supporter.
+   Aucun navigateur web n'a cette capacité, vous devez utiliser un autre client comme fexsend, schwuppdiwupp ou F*IX,
+   voir http://$HTTP_HOST$/tools.html
+
+Q: Mon nvaigateur web ne peut pas démarrer le client java F*IX, avec comme message d'erreur : "found no java runtime environment, cannot start F*IX upload applet"
+A: un plugin java pour votre navigateur est manquant. Sur Debian et Ubuntu, vous pouvez l'installer avec :
+   sudo aptitude install sun-java6-plugin
+
+Q: Lorsque j'appuie sur [ESC] dans firefox, l'upload est annulé. Pourquoi ?
+A: C'est une fonctionnalité intégré à Firefox. ESC termine l'opération courante.
+   Solution simple: ne pas appuyer sur ESC dans Firefox.
+   Solution complexe: demander aux développeurs de Firefox d'ajouter la configuration du clavier.
+
+Q: Firefox 3 se bloque lors de l'upload d'un fichier et je ne vois pas la barre de progression ?
+A: C'est un bug connu dans Firefox 3.6.23. Solution: passer à Firefox 7.
+
+Q: Envoyer un fichier en tant qu'utilisateur F*EX est facile, mais comment recevoir des fichiers de personnes extérieures ?
+A: Vous pouvez les enregistrer comme sous-utilisateurs ou créer un group F*EX via le menu "Configuration utilisateur & Gestion"
+
+Q: Parfois je peux télécharger un fichier plus d'une fois, surtout lorsque je le fais rapidement. Est-ce que la fonction de suppression automatique est défectueuse ?
+A: Le serveur F*EX a un délai d'une minute après le premier téléchargement réussi pendant lequel le fichier reste disponible. Cela est nécessaire
+car certains "gestionnaires de téléchargements" lancent plusieurs téléchargements du même fichier à la fois. Sinon, ils afficheraient une erreur à l'utilisateur. Votre administrateur F*EX a laissé AUTODELETE=DELAY par défaut, ce qui signifie que le nettoyage automatique est appelé une fois par jour.

+   Les utilisateurs avancés (use the source, Luke !) peuvent activer l'option "ne pas supprimer après téléchargement".
+
+Q: La rétentation par défaut est trop courte pour moi, j'ai besoin de plus. Comment puis-je l'augmenter ?
+A: Utilisez fexsend, demandez à votre fexmaster ou bien lisez le code source :-)
+
+Q: J'ai envoyé un second fichier avec le même nom, mais le destinataire n'a pas reçu deuxième message de confirmation. Pourquoi ?
+A: Un fichier avec le même nom et le même destinataire écrase le premier si il est toujours présent, un deuxième e-mail de notification pour un même fichier n'a pas tellement de sens.
+   
+Q: Je ne peux pas télécharger des fichiers avec Internet Explorer, il me dit : "Cannot open Internet site". Que dois-je faire ?
+A: Utilisez Firefox ou tout autre navigateur compatible Internet, ce qui n'est pas le cas d'Internet Explorer. Cela fait parti des nombreux bugs d'Internet Explorer.

+F*EX - File EXchange
+
+

+
F*EX - Frams' Fast File EXchange

+
+

+

+F*EX (Frams' Fast File EXchange) est un service pour envoyer des fichiers
+volumineux d'un utilisateur A à un utilisateur B.
+

+L'expéditeur upload le fichier au serveur F*EX en utilisant
+un formulaire WWW et le destinataire reçoit automatiquement
+une notification.
+

+
+Vous vous dîtes:
+

+  Pourquoi aurais -je besoin d'un autre service de transfert de fichier ?!

+  J'ai déja l'e-mail, le ftp, ssh et même sendfile !
+

+

+Je réponds:
+

+  Vous avez toujours besoin de F*EX :-)
+

+

+  
+Par exemple, vous voulez envoyer à vos amis la dernière vidéo de vos vacances (1 GB).
+Vous avez les possibilités suivantes (et les problèmes):

+
+
    
+  
  • envoyer un DVD par la voie postale
    
+      Hors de question - nous vivons en <> après l'invention d'Internet. C'est pour les grand-pères.
+      
    
+  
  • utiliser l'e-mail
    
+      La plupart des serveurs e-mail ont une limite de 10 MB par message et très souvent un quota d'utilisation de quelques centaines de méga-octets.
+      
    
+  
  • uucp
    
+      Et pourquoi pas du marbre et un burin ?
+      
    
+  
  • ssh
    
+      Vous avez le mot de passe de vos amis ou bien vous êtes prêts à leur donne le votre, juste pour un transfert de fichier ?
+      
    
+  
  • ftp
    
+      
      
+        
    • Quel serveur ?
+        
    • Quel compte, quel mot de passe ?
+        
    • Vous ne vous souciez pas d'envoyer des mots de passes non chiffrés et des fichiers sur un Internet non sécurisé ?
+        
    • Est-ce que votre proxy support le ftp passif ?
+        
    • Dans le cas d'un ftp anonyme :
+          
        
+            
      • Est-ce qu'il permet des uploads de 1GB ?
+            
      • Est-ce qu'il permet de supprimer le fichier uploadé ?
+            
      • Qui peut télécharger votre fichier ?
+            
      • Qui peut supprimer votre fichier ?
+            
      • Vous devez envoyer à votre ami l'URL de téléchargement, il doit vous informer
+                que le download s'est bien passé et vous devez supprimer le fichier
+                .
        
+                C'est plutôt pénible.
+          
      
+      
    
+      
    
+  
  • http
    
+      
      
+        
    • Pas d'upload par défaut et de gestion des utilisateurs. Cela doit être programmé
+	
    • Pas de notification automatique
+	
    • Pas d'effacement automatique
+	
    • Peu de serveur http peuvent gérer des fichiers de plus de 2GB
+      
    
+      
    
+  
  • sendfile
    
+      
      
+	
    • Vous utilisez UNIX et sendfile est installé ?
+	
    • Votre destinataire utilise UNIX et a sendfile d'installé ?
+	
    • Ni vous ou votre destinataire n'a le port 487 bloqué par un firewall ?
+      
    
+      
    
+  
  • Des services commerciaux comme DropLoad, ALLPeers, YouSendIt, etc
    
+      
      
+        
    • Quel limite ont-ils (le plupart: < 2 GB)?
+	
    • Quid de la sécurité et de la confidentialité : est-ce vos fichiers seront entre de bonnes mains ?
+	
    • Est-ce qu'ils sont opensource ou propriétaire ?
+	
    • Est-ce qu'ils sont accessibles avec n'importe quel navigateur ou bien avez-vous besoin de java, active-X, flash ou d'autres plugins ésotériques ?
+	
    • Est-ce qu'ils vont encore exister d'ici quelques mois?
      
+           (DropLoad, ALLPeers et drop.io ont déja mis la clé sous la porte)
+      
    
+      
    
+

+

+Si vous avez répondu "non" à une seule de ces questions, alors vous avez besoin de F*EX
+

+
Principales fonctionnalités de F*EX

+

+
    
+  
  • transfert de fichier de taille virtuellement infini
+  
  • le destinataire et l'expéditeur ont uniquement besoin d'un e-mail et d'un navigateur web, ils n'ont pas besoin d'installer de logiciels.
+  
  • reprise d'upload et de téléchargement en cas de défaillance
+  
  • notification automatique du destinataire
+  
  • suppression automatique après un téléchargement
+  
  • suppression automatique après un délai ajustable (par défaut: 5 jours)
+  
  • les utilisateurs F*EX peuvent créer des URLs d'upload à usage unique pour des utilisateurs extérieurs
+  
  • les utilisateurs F*EX peuvent créer des sous-utilisateurs qui ne pourront envoyer des fichiers uniquement à cet utilisateur
+  
  • les utilisateurs F*EX peuvent créer des groupes, similaire à des listes de diffusions, mais pour des fichiers
+  
  • maintenance réduite au minimum : pas d'interventations de l'administrateur nécessaires mise à part la création de nouveaux utilisateurs
+  
  • l'envoi à plusieurs destinataires ne nécessite pas le stockage d'autant de fichiers sur le serveur
+  
  • F*EX est un service web HTTP qui ne nécessite pas de contourner les parre-feux. 
+  
  • support des flux
+  
  • pour les vrais utilisateurs UNIX, il existe les programmes shell fexsend et fexget afin d'éviter l'utilisation ennuyeuse de l'interface web
+  
  • protocole et code source librement disponible (Perl Artistic)
+

+
+
Parlons de SEX

+F*EX a un ami : Stream EXchange (SEX).

+Vous pouvez imager SEX comme un tube UNIX réseau s'appuyant sur un relais.
+Cela peut s'avérer utile pour envoyer des données d'un utilisateur A à un utilisateur B lorsque A et B ne peuvent établir
+une connexion directe, mais que chacun peut accéder en HTTP au serveur SEX. Pour une intégration sans peine avec les outils UNIX,
+il y a les commandes shell sexsend et sexget.
+

+L'authentifaction est la même qu'avec F*EX

+F*EX (File EXchange)
+est un service pour envoyer des fichiers très volumineux (grand, énorme, géant, ...).
+

+L'expéditeur (vous) upload le fichier vers un serveur F*EX et le destinataire reçoit automatiquement un message
+de notification par mail avec l'URL de téléchargement.

+Après un téléchargement ou après $keep_default jours, le serveur efface le fichier.
+F*EX n'est pas un système d'archivage!
+

+Voir les questions & réponses.

+

+  $ENV{SERVER_ADMIN}

+

+EOD
+
+$info_2 = <

+Après soumission de votre fichier pour l'upload, vous verrez une barre de progression
+(si vous avez javascript activé et que les popups sont autorisés)
+

+REMARQUE: La plupart des navigateurs ne peuvent pas uploader des fichiers > 2 GB!

+Si votre fichier est plus gros, vous devez utiliser un client F*EX spécial.

+Vous devez aussi en utiliser un pour la reprise d'upload interrompu. Votre navigateur ne peut pas le faire.
+

+Pour les utilisateurs de Firefox : ne pas appuyer sur [ESC] parce que cela stoppera l'upload !

+
+Cuestións meta:
+===============
+
+Q: Por que o nome "F*EX" e non directamente "FEX"?
+
+A: No momento de facerse público xa había unha (antigo) aplicativo chamado "FEX" en
+   freshmeat.net.
+
+
+Q: Por que non usar un servizo comercial como
+   DropLoad, ALLPeers, YouSendIt, etc?
+
+A: Teñen un límite de 2 GB ou menor.
+   A súa seguranza e privacidade son descoñecidas.
+   Non se basean en código fonte aberto.
+   Non hai clientes de UNIX (CLI) para eles.
+   Necesitan java, active-X, flash ou outros endemoñados complementos.
+   Descoñécese canto tempo van funcionar - DropLoad e ALLPeers xa pecharon
+   as súas portas.
+
+
+Q: Por que un camelo no logo?
+
+A: O logo inspirouse no camelo de Perl, pero baseáse en Steiff, un camelo de peluxe,
+   co cal constituímos o noso tándem. O logo foi debuxado
+   por Beate
+   http://fex.rus.uni-stuttgart.de/Vortrag/tosa.html
+
+
+Q: Onde podo eu obter as fontes de F*EX?
+
+A: http://fex.rus.uni-stuttgart.de/fex.html
+
+
+Q: Que necesito para instalar F*EX?
+
+A: Un servidor UNIX con entrada no DNS e smtp para o correo de saída.
+   E debe ser root nese servidor.
+
+
+Q: Que é o DNS e smtp?
+
+A: Non instale F*EX. Está alén das súas posibilidade.
+
+
+Q: Quen e o autor?
+
+A: Ulli Horlacher <framstag@rus.uni-stuttgart.de>
+
+
+Q: Que licenza ten F*EX?
+
+A: De software libre, Perl Artistic, vexa http://fex.rus.uni-stuttgart.de/doc/Licence
+
+
+Q: Hai unha lista de correo de F*EX?
+
+A: https://listserv.uni-stuttgart.de/mailman/listinfo/fex
+
+
+Q: Onde podo obter asistencia comercial para F*EX?
+
+A: Contacto fex@nepustil.net http://www.nepustil.net/
+
+
+Q: Teñeo máis/outras preguntas diferentes!
+
+A: Preguntarlle ao autor <framstag@rus.uni-stuttgart.de>
+
+
+
+Preguntas de usuario:
+=====================
+
+Q: Que é o "auth-ID"?
+
+A: O auth-ID é unha identificación interna que autentica o usuario.
+   Será a primeira xerada polo admin ou o proceso de rexistro automático
+   e pode despois modificalo vostede, o usuario. Trátase dun contrasinal
+   de baixa seguranza.
+
+
+Q: Podo usar un proxy HTTP?
+
+A: Si.
+
+
+Q: Carguei un ficheiro ENORME pero equivoqueime ao escribir o enderezo do destinatario. Agora teño
+   un erro de entrega de correo. Debo volver cargar ese ENORME ficheiro?
+
+A: Non, non fai falta. Pode redirixir o ficheiro con
+   http://$HTTP_HOST$/rup
+
+
+Q: Cargue un ficheiro ENORME pero esquecín outro destinatario.
+   Debo volver cargar ese ENORME ficheiro?
+
+A: Non, non é necesario. Pode reenviar copia do ficheiro con
+   http://$HTTP_HOST$/foc
+
+
+Q: Non podo cargar ficheiros > 2 GB co meu navegador web!?
+
+A: Todos os navegadores teñen defectos na implementación dos
+   seus formularios HTML. O límite máis frecuente é de 2 GB, ás veces 4 GB.
+
+   Debe usar un cliente especial de F*EX para cargar ficheiros > 2 GB, vexa
+   http://$HTTP_HOST$/tools.html
+
+
+Q: A miña descarga abortouse antes de rematar. Podo retomar esa descarga?
+
+A: F*EX permite retomar e descargar, pero o seu cliente tamén debe permitir
+   esta funcionalidade. Firefox por exemplo carece desta funcionalidade HTTP, necesitará
+   outro cliente como Opera, wget ou fexget.
+
+
+Q: A miña carga foi abortada antes de rematar. Podo retomar esa carga?
+
+A: F*EX permite retomar a carga, pero o seu cliente debe permitir vbnm, 1tupports resuming at upload, but your client also has to support it.
+   No web browser has this feature, you need a special F*EX client like
+   fexsend, schwuppdiwupp or F*IX.
+   See http://$HTTP_HOST$/tools.html
+
+
+Q: O meu navegador non pode iniciar o cliente java F*IX, que indica:
+   "non se atopou un entorno de execución java, non se pode iniciar F*IX o miniaplicativo de carga"
+
+A: Non se localiza un complemento java do navegador. En Debian e Ubuntu pode
+   instalalo con: "sudo aptitude install sun-java6-plugin"
+
+
+Q: Cando premo[ESC] no Firefox a carga cancélase. Por que?
+
+A: Esta é unha funcionalidade interna do Firefox: ESC termina a operación actual.
+   Solución simple: non prema ESC no Firefox.
+   Solución complexa: pídalles aos desenvolvedores do Firefox que engadan un atallo de teclado.
+
+
+Q: O envío como un usuario F*EX é doado, pero como recibir ficheiros doutros,
+   de fóra?
+
+A: Rexístreos como subusuarios ou cree un grupo F*EX
+   con http://$HTTP_HOST$/fuc
+
+
+Q: Ás veces podo descargar un ficheiro máis dunha vez, especialamente cando
+   o repito rapidamente. Está a funcionalidade de auteliminación defectuosa?
+
+A: O servidor F*EX ten un períod de gracia de 1 minuto despois da primeira
+   descarga correcta no cal o ficheiro aínda está dispoñíbel. Isto é necesario
+   porque algúns "xestores de descargas" estúpidos solicitan o ficheiro
+   varias veces á vez. Caso contrario poderían indicar un erro ao usuario.
+
+A: O seu fexmaster ten un conxunto AUTODELETE=DELAY como predeterminado, o que significa que
+   o proceso de autolimpeza realízase unha vez ao día.
+
+A: Os "Power users" ou usuarios con permisos (usa a forza, Luke!) poden establecer unha marca "non eliminar ata
+   despois da descarga".
+
+
+Q: O período de reserva predeterminado é demasiado curto para min, cómpreme máis. Como podo estabelecelo?
+
+A: Use fexsend, pídallo ao seu fexmaster ou lea o código fonte :-)
+
+
+Q: Non podo descargar ficheiros con Internet Explorer, dime "Non se pode
+   abrir o sitio da Internet". Que debería facer?
+
+A: Use Firefox ou calquera outro navegador compatíbel con Internet, xa que Internet
+   Explorer non o é. Este é un de tanto defectos do Internet Explorer.
+
+
+
+
+Preguntas de administrador:
+===========================
+
+Q: Non podo instalar un servidor web como fexsrv, porque non teño permisos de root
+   Hai algunha versión en puro CGI de F*EX que funcione cun servidor web Apache?
+
+A: F*EX está intimamente unido a fexsrv por varias razóns (rendemento, límite de
+   tamaño de ficheiro, concepto de sesiónt, etc.) e non se pode executar como CGI
+   con Apache.
+   Pero pódelle botar un ollo a
+   http://gpl.univ-avignon.fr/filez/
+   http://freshmeat.net/projects/eventh/
+   http://www.schaarwaechter.de/sp/projekte/dateiaustausch.html (só en alemán!)
+   que implementa un intercambio de ficheiros como puros CGI, pero cun tamaño límite de 2 GB por ficheiro.
+
+
+Q: F*EX non funciona! Non podo conectarme co meu navegador web!
+
+A: Comprobe o seu enrutamento, filtros ip e configuración de devasa.
+   Tamén comprobe se o seu xinetd está ligado cun tcp-wrapper e configúreo
+   correctamente (hosts.allow).
+   F*EX necesita o porto 80/tcp (HTTP) e o porto opcional 443/tcp (HTTPS).
+
+
+Q: F*EX é complicado de máis! Necesito algo máis simplificado.
+
+A: Probe http://www.home.unix-ag.org/simon/woof.html
+
+
+Q: Como podo integrar F*EX no xestor de usuarios do meu sitio?
+
+A: F*EX ten varios módulos de autenticación:
+   local, RADIUS, LDAP, mailman e POP
+   Para os 4 últimos, contacte por favor co autor framstag@rus.uni-stuttgart.de
+
+
+Q: Que que todos os meus usuarios locais poidan usar F*EX automatimente. Como?
+
+A: Permítaos rexistrarse a si mesmos con http://yourfexserver/fur
+   Ten que editar lib/fex.ph e establecer (exemplo):
+   @local_hosts = qw(127.0.0.1 10.10.100.0-10.10.255.255);
+   @local_domains = qw(flupp.org ulm.sub.net);
+   (Por suposto, ten que engadir os seus servidores/redes locais reais!)
+
+
+Q: Necesito máis seguranza! Como podo activar HTTPS?
+
+A: Lea doc/SSL e busque "fop_auth" en doc/concept
+
+
+Q: Necesito un aspecto corporativo. Como podo configurar F*EX neste sentido?
+
+A: Vexa a variábel @H1_extra en fex.ph e pode engadir o código HTML a
+   htdocs/header.html
+
+A: Vexa htdocs/fup_template.html, modifíqueo ás súas necesidades e úseo como a súa
+   páxina de inicio.
+
+
+Q: F*EX é demasiado complicado para os meus pobres usuarios. Necesito un formulario de
+   carga simmplificado.
+
+A: Vexa htdocs/fup_template.html
+
+
+Q: Quero que os correos Ccc a (ao usuario admin) se envíen a outro enderezo.
+
+A: Use procmail ou escriba OTHERADDRESS en /home/fex/.forward
+
+
+Q: Podo obter unha versión localizada no meu idioma?
+
+A: Sempre coa súa axuda, si. Contacte co autor framstag@rus.uni-stuttgart.de
+
+
+Preguntas en miscelánea:
+========================
+
+Q: F*EX é fantástico! Podo unirme ao equipo de desenvolvemento? Que hai que facer?
+
+A: Contacte co autor framstag@rus.uni-stuttgart.de
+   As funcionalidades buscadas son:
+
+     - un complemento F*EX para o Thunderbird ou o Outlook
+     - máis (outras) idiomas dispoñíbeis

+F*EX - File EXchange
+

+
F*EX - Frams' Fast File EXchange

+
+

+

+F*EX (Frams' Fast File EXchange) é un servizo para enviar voluminosos
+(grandes, enormes, xigantes, ...) ficheiros dun usuario A a un usuario
+B.
+

+O remisor carga o ficheiro no servidor F*EX usando un formulario WWW e o receptor automaticamente obtén unha notificación vía correo cun enderezo URL para descargar. 
+

+
+Vostede dirá:
+

+  Por que necesito outro servizo para transferencia de ficheiros?!
Teño correo, ftp, ssh e mesmo sendfile!
+

+

+Ao que respondo:
+

+  Aínda así necesita F*EX :-)
+

+

+  
+Por exemplo, quere enviar ao seu amigo o video das últimas vacacións (1 GB).  Ten as seguintes posibilidades (e problemas):

+
+
    
+  
  • o envío dun DVD vía correo postal
    
+      Nin o vou considerar - vivimos na época actual 
+      <> 
+      despois da invención da Internet!
+      O envío de soportes multimedia (físicos) é para avoíñas.
+      
    
+  
  • o uso do correo
    
+A maior parte dos servidores de correo teñen un límite de 10 MB por
+mensaxe e unha cota de uso de disco duns poucos 100 MB por usuario ou
+mesmo menor. 
    
+  
  • uucp
    E por que non escritura cuneiforme en laxes de pedra?
+      
    
+  
  • ssh
    Ou ben tes os contrasinais dos teus amigos ou ben terás que darlles a túa
+      - fai falta iso só para transferir un ficheiro?
+      
    
+  
  • ftp
    
+      
      
+        
    • Usando que servidor ftp?
+        
    • Usando que conta, que contrasinal?
+        
    • Non se lle pasará pola cabeza enviar contrasinais sen cifrar e ficheiros na incerta Internet?
+        
    • O seu proxy permite o ftp pasivo?
+        
    • No caso de ftp anónimo:
+          
        
+            
      • Permite cargas de 1 GB?
+            
      • Permite eliminar a carga despois?
+            
      • Quen pode descargar ademais o seu ficheiro?
+            
      • Quen pode eliminar o seu ficheiro?
+            
      • Ten
+que enviarlle ao seu amigo/a o URL de descarga, el ten que informarte
+de que o descargou correctamente, despois ten vostede que eliminalo.
        
+                Definitivamente: unha merda pinchada nun pao.
+          
      
+      
    
+      
    
+  
  • http
    
+      
      
+        
    • Nin carga predeterminada nin xestión de usuario - debe ser programada
      • 
+      
    • Sen autonotificación
+        
      • 
+
    • Sen autoeliminado
+        
    • Moi poucos servidores http poden xestionar ficheiros superiores a 2 GB
+      
    
+      
    
+  
  • sendfile
    
+      
      
+        
    • Executas un UNIX e tes o sendfile instalado?
+        
    • O teu receptor executa UNIX e ten o sendfile instalado?
+        
    • Nin ti nin o teu receptor ten unha devasa que bloquee o porto 487?
+      
    
+      
    
+  
  • servizos comerciais como DropLoad, ALLPeers, YouSendIt, etc
    
+      
      
+        
    • Que límite teñen (maiormente: < 2 GB)?
+        
    • Como andan de seguranza e privacidade: estarán os seus ficheiros gardados e seguros?
+        
    • Están baseados en software aberto ou en privativo?
+        
    • Están accesíbeis con calquera outro navegador ou cómpre usar java, active-X, flash ou outros complementos endemoñados?
+        
    • Funcionarán alén duns poucos meses?
      
+           (DropLoad, ALLPeers e drop.io xa pecharon as súas portas)
+      
    
+      
    
+

+

+Se respondeu só unha vez "non" ás cuestións anteriores, entón necesita F*EX.
+

+
Principais funcionalidades de F*EX

+

+
    
+  
  • transferencia de ficheiro ou  tamaño virtualmente ilimitada
+  
  • receptor e remitente só necesitan un programa de correo e un navegador web -
+      de calquer clase, non teñen que instalar ningún software
+  
  • REENVIAR and REOBTER para retomar despois de fallos de ligazón ata que se envíe o último byte
+  
  • autonotificación de receptor
+  
  • autoeliminación despois da descarga
+  
  • autoeliminación despois dunha data de expiración (predeterminada: 5 días)
+  
  • os usuarios con plenos dereitos poden crear subusuarios, que poden envíar soamente a este usuario pleno
+  
  • os usuarios con plenos dereitos poden crear grupos, en analoxía coas listas de correo, pero para ficheiros
+  
  • sen mantemetno: non se necesita interacción acompañando a creación de novas contas con F*EX
+  
  • o envío a múltiples receptores necesita capacidade de almacenamento no servidor só unha vez
+  
  • F*EX é un servizo web por HTTP e non necesita túneles nin devasas
+  
  • permite a distribución de fluxos, tamén
+  
  • para usuarios reais de UNIX, hai aplicativos da shell como fexsend e fexget que evitan o uso impertinente de navegador
+  
  • o protocolo e o código fonte están dispoñíbeis libremente (Perl Artistic)
+

+
+
Falemos de SEX

+F*EX ten un compañeiro: Stream EXchange (SEX).
Pode
+imaxinar SEX como unha rede de tubarías UNIX cun reenviador (relay)
+entre elas.
+Isto pode ser moi práctico para intercambiar datos entre o usuario A e
+o usuario B alí onde A e B non poden establecer unha conexión directa,
+pero ambos poden conectar vía HTTP ao servidor
+SEX. Para unha integración perfecta na cadea de ferramentas UNIX, hai
+ferramentas de shell como sexsend e sexget.
+

+A autenticación é a mesma que con F*EX.

Dieses Dokument ist veraltet. Bitte benutzen Sie die
+    englische FAQ.

+
+Allgemeine Fragen:
+==================
+
+F: Warum der Name "F*EX" und nicht einfach "FEX"?
+
+A: Zur Zeit der Veröffentlichung existierte bereits ein (älteres) Programm 
+   namens "FEX" auf freshmeat.net.
+   
+
+F: Warum nicht einen kommerziellen Dienst benutzen wie
+   DropLoad, ALLPeers, YouSendIt, etc?
+   
+A: Solche Dienste haben ein Limit von 2 GB oder sogar weniger.
+   Es ist unklar wie es bei ihnen mit Sicherheit und Datenschutz aussieht.
+   Sie basieren nicht auf Open Source.
+   Es gibt keine UNIX (CLI) Clients für sie.
+   Sie brauchen Java, Active-X, Flash oder andere bösartige Plugins.
+   Es ist unklar wie lange sie noch existieren werden - DropLoad und ALLPeers
+   haben bereits aufgehört zu existieren.
+
+
+F: Warum ein Kamel als Logo?
+
+A: Das Logo war inspiriert durch das Perl Kamel, zu Grunde liegt aber ein 
+   Plüschkamel von Steiff welches auf unserem Renn-Tandem mitfährt. 
+   Das Logo wurde von meiner Stokerin Beate gezeichnet, siehe
+   http://fex.rus.uni-stuttgart.de/Vortrag/tosa.html
+
+
+F: Wo kann ich die F*EX Sourcen bekommen?
+
+A: http://fex.rus.uni-stuttgart.de/fex.html
+
+
+F: Was braucht man um F*EX installieren zu können?
+
+A: Ein UNIX Server mit DNS Eintrag und smtp für ausgehende E-Mail.
+   Und Sie müssen root auf diesem Server sein.
+   
+
+F: Was ist DNS und smtp?
+
+A: Installieren Sie kein F*EX. Es ist jenseits Ihres Horizonts.
+
+
+F: Wer ist der Autor?
+
+A: Ulli Horlacher <framstag@rus.uni-stuttgart.de>
+
+
+F: Unter welcher Lizenz läuft F*EX?
+
+A: Perl Artistic Freie Software, siehe http://fex.rus.uni-stuttgart.de/doc/Licence
+
+
+F: Gibt es eine F*EX Mailing Liste?
+
+A: https://listserv.uni-stuttgart.de/mailman/listinfo/fex
+
+
+F: Wo kann ich einen kommerziellen Support für F*EX bekommen?
+
+A: Nehmen Sie Kontakt auf mit fex@nepustil.net http://www.nepustil.net/
+
+
+F: Ich habe noch weitere Fragen bezüglich dieses Dokuments!
+
+A: Fragen Sie den Autor <framstag@rus.uni-stuttgart.de>
+
+
+Benutzerfragen:
+===============
+
+Q: Was ist die "auth-ID"?
+
+A: Mit Hilfe der auth-ID werden Sie auf dem Server als ein authorisierter 
+   Benutzer identifiziert. Die auth-ID wird zuerst vom Administrator oder 
+   durch automatische Registrierung vergeben und kann später durch Sie 
+   geändert werden. Bitte beachten Sie dass man hier keine wertvollen
+   Passwörter verwenden sollte weil diese unverschlüsselt auf dem 
+   Server liegen.
+
+
+F: Kann ich einen HTTP-Proxy verwenden?
+
+A: Ja
+
+
+F: Ich habe eine RIESIGE Datei an eine falsche Adresse versendet. Jetzt 
+   bekomme ich eine Fehler-Meldung vom System. Muß ich die RIESIGE Datei
+   noch mal hochhladen?
+
+A: Nein, das ist nicht nötig. Sie können die Datei einfach weiterleiten 
+   mit Hilfe von http://$HTTP_HOST$/rup
+
+
+F: Ich habe eine RIESIGE Datei versendet doch leider habe ich noch einen 
+   Empfänger vergessen. Muß ich die RIESIGE Datei noch mal hochladen?
+
+A: Nein, das ist nicht nötig. Sie können die Datei einfach kopieren und
+   weiterleiten mit Hilfe von http://$HTTP_HOST$/foc
+
+
+F: Warum kann ich keine Dateien größer als 2 GB mittels Web-Browser 
+   hochladen?
+
+A: Alle Web-Browser die mir bekannt sind haben Fehler in ihrer HTML-FORM
+   Implementierung. Dadurch ergibt sich der Limit von 2 GB, manchmal 4 GB.
+
+   Sie müssen einen speziellen F*EX Client benutzen um Dateien größer 
+   als 2 GB hochzuladen, siehe http://$HTTP_HOST$/tools.html
+
+
+F: Mein Download brach frühzeitig ab. Kann ich ihn wieder aufnehmen?
+
+A: F*EX unterstützt Download-Wiederaufnahme, aber Ihr Client muss es ebenso 
+   unterstützen. Firefox zB fehlt diese HTTP Eigenschaft, daher benötigen 
+   Sie einen anderen Client wie opera, wget oder fexget.
+
+
+F: Mein Upload brach frühzeitig ab. Kann ich ihn wieder aufnehmen?
+
+A: F*EX unterstützt Upload-Wiederaufnahme, aber Ihr Client muss es ebenso 
+   unterstützen. Kein Web-Browser hat diese Unterstützung, Sie 
+   benötigen dfür einen speziellen F*EX Client wie
+   fexsend, schwuppdiwupp oder F*IX.
+   Siehe http://$HTTP_HOST$/tools.html
+
+
+F: Wenn ich die Taste [ESC] in Firefox drücke, dann wird der Upload 
+   abgebrochen. Warum?
+
+A: Das ist die eingebaute Funktion von Firefox: ESC unterbricht die 
+   laufende Operation. 
+   Einfache Lösung des Problems: 
+   [ESC] sollte man nicht drücken.
+   Komplizierte Lösung: 
+   bitten Sie die Firefox-Entwickler, eine Tastatur-Konfiguration hinzuzufügen
+
+
+F: Daten mit F*EX zu versenden ist einfach, wie kann ich aber Daten
+   von anderen (von der Aussenwelt) empfangen?
+
+A: Registrieren Sie sie als Ihre Subuser oder legen Sie eine F*EX Gruppe an.
+   
+
+F: Es kommt manchmal vor dass ich eine Datei mehrmals herunterladen kann, 
+   insbesondere wenn ich die Downloads schnell wiederhole. Ist etwa das 
+   automatische Löschen fehlerhaft?
+
+A: Der F*EX-Server wartet 1 Minute lang nach dem ersten erfolgreichen Download.
+   In dieser Zeit kann man die Datei nochmal herunterladen. Diese Wartezeit 
+   ist notwendig weil manche idiotische "Download Manager" die Datei gleich 
+   mehrmals anfordern. Ohne die Wartezeit würden sie dem Benutzer einen
+   Fehler melden.
+
+A: Ihr Fexmaster hat die Variable AUTODELETE auf DELAY gesetzt. Das hat
+   zur Folge dass das automatische Löschen nur einmal täglich stattfindet.
+
+A: Power-Benutzer (sehen Sie die Software-Quelltexte!) können den Flag
+   "nach dem Download nicht löschen" setzen.
+
+
+F: Die Standard Aufbewahrungszeit ist mir zur kurz. Wie kann ich diesen Wert 
+   erhöhen?
+
+A: Benutzen Sie fexsend, fragen Sie Ihren Fexmaster oder lesen Sie die 
+   Quelltexte :-)
+
+
+F: Ich kann Dateien mit dem Internet Explorer nicht herunterladen, es
+   meldet mir "Die Internet-Seite ist nicht verfügbar". Was soll ich tun?
+
+A: Benutzen Sie Firefox oder anderen Internet-kompatiblen Web-Browser, was der 
+   Internet Explorer eben nicht ist. Das ist nur einer seiner vielen Bugs.
+
+
+Administrator Fragen:
+=====================
+
+F: Ich kann keinen Web-Server wie fexsrv aufsetzen, mir fehlen dazu die
+   Rechte. Gibt es vielleicht eine reine CGI-Version von F*EX die
+   unter dem Apache Web-Server läuft?
+
+A: fexsrv ist ein fester Bestandteil von F*EX, dazu gibt es viele Gründe 
+   (Leistung, maximale Dateigröße, Session Konzept usw). So kann F*EX nicht 
+   als CGI unter Apache laufen, Sie könnten sich aber das hier anschauen:
+   
+   http://gpl.univ-avignon.fr/filez/
+   http://freshmeat.net/projects/eventh/
+   http://www.schaarwaechter.de/sp/projekte/dateiaustausch.html
+   
+   Das sind einfache CGI-Implementierungen von Daten-Übertragungssystemen,
+   jedoch begrenzt auf 2 GB.
+   
+
+F: F*EX funktioniert überhaupt nicht! Es kommt keine Verbindung zum Server mit 
+   meinem Web-Browser zustande!
+
+A: Prüfen Sie Ihr Routing, IP-Filter und die Firewall-Einstellungen.
+   Prüfen Sie auch ob Ihr xinetd mit dem TCP-Wrapper verlinkt ist und
+   konfigurieren Sie es richtig (hosts.allow).
+   F*EX braucht den Port 80/tcp (HTTP) und optional den Port 443/tcp
+
+
+F: F*EX ist mir zu kompliziert! Ich brauche was einfacheres!
+
+A: Probieren Sie http://www.home.unix-ag.org/simon/woof.html
+
+F: Wie kann ich F*EX in das bestehende Benutzer-Management in meinem Netzwerk 
+   integrieren?
+
+A: F*EX hat verschiedene Authentifizierungs-Module:
+   lokal, RADIUS, LDAP, mailman und POP
+   Bezüglich der letzten 4 kontaktieren Sie bitte den Autor.
+
+
+F: Ich möchte dass alle meine lokalen Benutzer automatisch F*EX benutzen 
+   können. Wie geht das?
+
+A: Lassen Sie sie sich selbst registrieren.
+   Dazu müssen Sie lib/fex.ph editieren (Beispiel):
+   
+   @local_hosts = qw(127.0.0.1 10.10.100.0-10.10.255.255);
+   @local_domains = qw(flupp.org ulm.sub.net);
+
+   Natürlich müssen Sie Ihre echten Hosts/Networks eigeben!
+
+
+F: Ich brauche mehr Sicherheit! Wie kann ich HTTPS benutzen?
+
+A: Lesen Sie doc/SSL und schauen Sie auch nach "fop_auth" in doc/concept 
+
+
+F: Die F*EX-Startseite sollte an unsere Firmen-Seiten angepaßt werden. 
+   Wie kann ich F*EX entsprechend konfigurieren?
+
+A: Siehe Variable @H1_extra in fex.ph, ausserdem können Sie htdocs/header.html
+   hinzufügen.
+
+A: Nehmen Sie fup_template.html, modifizieren Sie die Vorlage nach Ihren 
+   Wünschen und nutzen Sie diese als Ihre Startseite.
+
+
+Sonstige Fragen:
+================
+
+F: F*EX ist großartig! Wie kann ich mich dem Entwicklungs-Team anschließen? 
+   Was muß noch gemacht werden?
+
+A: Kontaktieren Sie den Autor wegen:
+
+   - ein F*EX plugin für Outlook
+   
+   - weiteren Übersetzungen in andere Sprachen - Latein wäre toll! :-)

+

+
F*EX - Frams' Fast File EXchange

+
+

+

+F*EX (Frams' Fast File EXchange) ist ein Dienst, um große (sehr große, riesige,
+gigantische, ...) Dateien von User A zu User B zu senden.
+

+Der Absender lädt die Datei über ein  
+WWW upload Formular auf den F*EX Server hoch und der Empfänger 
+bekommt automatisch eine Benachrichtigungs-E-Mail mit der Download-URL.
+

+
+Sie fragen vielleicht:
+

+  Warum brauche ich noch einen Service für Dateitranfer?!

+  Ich habe E-Mail, FTP, SSH und sogar sendfile!
+

+

+Ich sage:
+

+  Sie brauchen F*EX trotzdem :-)
+

+

+  
+Sie möchten zum Beispiel einem Freund das letztes Urlaubsvideo senden (1 GB).
+Sie haben dazu folgende Möglichkeiten (und Probleme):

+
+
    
+  
  • eine DVD per Briefpost verschicken
    
+      Steht außer Frage - wir leben im Jahr 
+      <> 
+      nach der Erfindung des Internet!
+      Versand von (Hardware-)Medien ist etwas für Opas.
+      
    
+  
  • E-Mail benutzen
    
+      Die meisten E-Mail Server haben ein Limit von 10 MB pro E-Mail
+      und ein Speicherkontingent von wenigen 100 MB pro User oder sogar weniger.
+      
    
+  
  • UUCP
    
+      Warum nicht gleich Keilschrift-Zeichen in Tonplatten eindrücken?
+      
    
+  
  • SSH
    
+      Sie haben das Passwort Ihres Freundes oder sind gewillt, ihm Ihres zu geben
+      - nur für einen Datei-Transfer?
+      
    
+  
  • FTP
    
+      
      
+        
    • Welchen FTP Server benutzen?
+        
    • Welchen Account benutzen, welches Passwort?
+        
    • Stört es Sie unverschlüsselte Passwörter über das unsichere Internet zu übertragen?
+        
    • Unterstützt Ihr Proxy passives FTP?
+        
    • Im Fall von anonymen FTP:
+          
        
+            
      • Erlaubt es 1 GB Uploads?
+            
      • Kann man den Upload nach dem Transfer wieder löschen?
+            
      • Wer kann Ihre Datei noch downloaden?
+            
      • Wer noch kann Ihre Datei löschen?
+            
      • Sie müssen Ihrem Freund die Download-URL zukommen lassen und er
+                muss Sie über den erfolgreichen Download informieren, danach müssen Sie die Datei löschen.
        
+                Alles in Allem: eine nervige Sache.
+          
      
+      
    
+      
    
+  
  • HTTP
    
+      
      
+        
    • Es gibt keine standardmäßige Upload- und User-Verwaltung (muss erst programmiert werden)
+        
    • Keine Auto-Benachrichtigung
+        
    • Kein automatisches Löschen
+        
    • Sehr wenige HTTP Server können mit Dateien größer 2 GB umgehen
+      
    
+      
    
+  
  • sendfile
    
+      
      
+        
    • Sie benutzen UNIX und haben sendfile installiert?
+        
    • Ihr Empfänger benutzt UNIX und hat sendfile installiert?
+        
    • Weder Ihr Empfänger noch Sie selbst haben eine Firewall die Port 487 blockiert?
+      
    
+      
    
+  
  • Kommerzielle Dienste wie DropLoad, ALLPeers, YouSendIt, etc
    
+      
      
+        
    • Welche Beschränkungen haben sie? (meist: < 2 GB)?
+        
    • Was ist mit Sicherheit und Privatsphäre: werden Ihre Dateien sicher und geschützt sein?
+        
    • Basieren sie auf Open Source- oder proprietärer Software?
+        
    • Sind sie mit jedem Browser benutzbar oder braucht man Java, Active-X, Flash oder andere üble Plugins?
+        
    • Werden sie länger als ein paar Monate existieren?
      
+           (DropLoad und ALLPeers haben ihren Betrieb schon eingestellt)
+      
    
+      
    
+

+

+Wenn Sie auch nur eine der Fragen von oben mit "Nein" beantwortet haben, dann brauchen Sie F*EX.
+

+
Hauptmerkmale von F*EX

+

+
    
+  
  • Datei-Transfer mit praktisch unbegrenzter Dateigröße
+  
  • Empfänger und Absender brauchen lediglich ein E-Mail Programm und einen Web-Browser -
+      es muss keine zusätzliche Software installiert werden
+  
  • RESEND und REGET für Wiederaufnahme bei Link Fehlern beim letzten gesendeten Byte
+  
  • Auto-Benachrichtigung der Empfänger
+  
  • automatisches Löschen nach Download
+  
  • automatisches Löschen nach Ablaufdatum (Standard: 5 Tage)
+  
  • Full-User können Sub-User erstellen, die dann nur an den Full-User senden dürfen
+  
  • Full-User können Gruppen erstellen, eine Analogie zu Mailinglisten, aber für Dateien
+  
  • wartungsfrei: bis auf die Erstellung neuer F*EX Accounts ist keine Interaktion eines Admins erforderlich
+  
  • Für das Senden an mehrere Empfänger wird auf dem Server nur einmal Speicherplatz verbraucht
+  
  • F*EX ist ein HTTP-Web-Dienst und benötigt keine Firewall-Tunnel
+  
  • Unterstützung für Streams
+  
  • für UNIX Benutzer gibt es die Shell-Programme fexsend und fexget, um den lästigen Gebrauch von Webbrowsern zu umgehen
+  
  • Protokoll und Quellcode sind frei verfügbar (Perl Artistic)
+

+
+
Lassen Sie uns über SEX sprechen

+F*EX hat einen Begleiter: Stream EXchange (SEX).

+Man kann sich SEX als netzwerkweite UNIX Pipes mit einem Relay dazwischen vorstellen.
+Das kann hilfreich sein, wenn man Daten von User A zu User B leiten will,
+ohne dass A und B eine direkte Verbindung zueinander aufbauen können, aber beide sich
+über HTTP zum SEX Server verbinden können.
+Für eine nahtlose Integration in die UNIX Programm Reihe,
+gibt es die Shell-Programme sexsend und sexget.
+

+Die Authentifizierung ist dieselbe wie bei F*EX.

+
+
+Domande Generiche:
+==================
+
+Q: Perche' il nome e' "F*EX" invece del piu' corto "FEX"?
+
+A: Al momento della pubblicazione c'era gia' un (vecchio) programma
+   nominato "FEX" su freashmeat.net
+
+
+Q: Perche' non usare un servizio commerciale come
+   DropLoad, ALLPeers, YouSendIt, ecc. ?
+
+A: Tutti hanno un limite di 2 GB o meno.
+   I loro livelli di sicurezza e privacy sono sconosciuti.
+   Non sono servizi basati su software open-source.
+   Non ci sono client UNIX (a linea di comando) per loro.
+   Hanno bisogno di java, Active-X, Flash o altri plug-in.
+   Non si sa quanto tempo sopravviveranno - DropLoad e ALLPeers hanno
+   gia' concluso la loro attivita'.
+
+
+Q: Perche' c'e' un cammello nel logo?
+
+A: Il logo e' stato ispirato al cammello del Perl, ma e' basato sul
+   cammello di peluche della Steiff che ci portiamo insieme con noi
+   nelle nostre corse con il tandem.
+   Il logo e' stato disegnato dal mio "fuochista" Beate
+   http://fex.rus.uni-stuttgart.de/Vortrag/tosa.html
+
+
+Q: Dovo posso prendere i sorgenti di F*EX ?
+
+A: http://fex.rus.uni-stuttgart.de/fex.html
+
+
+Q: Dove posso installare F*EX ?
+
+A: In un host UNIX con una entry DNS ed un SMTP per la spedizione
+   delle e-mail. Su questo server bisogna avere i privilegi di root.
+
+
+Q: Cosa sono DNS e SMTP?
+
+A: Lascia perdere F*EX. E' al di la' delle tue possibilita'.
+
+
+Q: Chi e' l'autore ?
+
+A: Ulli Horlacher <framstag@rus.uni-stuttgart.de>
+
+
+Q: Che tipo di licenza ha F*EX ?
+
+A: Perl Artistic free software, vedete http://fex.rus.uni-stuttgart.de/doc/Licence
+
+
+Q: C'e' una mailing list per F*EX ?
+
+A: https://listserv.uni-stuttgart.de/mailman/listinfo/fex
+
+
+Q: Dove posso trovare un servizio commerciale per F*EX ?
+
+A: Contattate fex@nepustil.net http://www.nepustil.net/
+
+
+Q: Ho altre domande che non trovo in questo documento.
+
+A: Chiedete all'autore <framstag@rus.uni-stuttgart.de>
+
+
+
+Domande Utente:
+===============
+
+Q: Cos'e' il campo "auth-ID" ?
+
+A: Il campo auth-ID e' un identificativo interno che individua l'utente;
+   e' lo username.
+   E' creato la prima volta o dall'amministratore o attraverso il processo
+   di registrazione automatico e puo' essere successivamente modificato
+   da te (che sei l'utente).
+   Pensa come se fosse una password a bassa sicurezza.
+
+Q: Posso usare un proxy HTTP ?
+
+A: Si'.
+
+
+Q: Ho caricato un file ENORME, ma ho fatto un errore di battitura
+   nell'indirizzo del destinatario. Ora mi trovo con una e-mail
+   di errore.
+   Devo effettuare di nuovo il caricamento di questo ENORME file?
+
+A: No, non e' necessario. Puoi ridirigere il file con
+   http://$HTTP_HOST$/rup
+
+
+Q: Ho caricato un file ENORME ma ho dimenticato uno dei destinatari.
+   Devo ricaricarlo?
+
+
+A: No, non e' necessario. Puo' inoltrare il file con
+   http://$HTTP_HOST$/foc
+
+
+Q: Posso caricare file di dimensioni > di 2 GB con il mio browser !?
+
+A: Tutti i browser che conosco hanno dei bug nella loro implementazione
+   delle FORM HTML.
+   Il limite e' per lo piu' di 2 GB, molto spesso e' di 4 GB.
+   Dovete usare uno speciale client F*EX per caricare file > 2GB,
+   vedete http://$HTTP_HOST$/tools.html
+
+
+Q: Il mio download si e' bloccato prima di finire.
+   Posso riprenderlo?
+
+A: F*EX supporta il recupero del download ma anche il vostro client deve
+   supportare questa funzione. Firefox, per esempio, non ha questa funzione,
+   serve un'altro client come Opera, Wget o Fexget.
+
+
+Q: Il caricamento del mio file si e' interrotto prima di finire.
+   Posso riprenderlo?
+
+A: F*EX supporta la ripresa del caricamento interrotto di un file ma anche
+   il client deve supportarlo. Nessun browser WEB ha questa funzionalita',
+   avete bisogno di uno speciale client F*EX come fexsend, schwuppdiwupp o F*IX.
+   Vedete http://$HTTP_HOST$/tools.html
+
+
+Q: Il mio browser WEB non puo' eseguire il client java F*IX
+   in quanto non trova l'ambiente java runtime e quindi
+   non puo' caricare la applet F*IX
+
+
+A: Manca il plug-in java per il vostro browser WEB. Sui sistemi Debian e
+   Ubuntu potete installarlo con questo comando:
+   "sudo aptitude install sun-java6-plugin"
+
+
+Q: Quando schiaccio [ESC] in firefox il caricamento si cancella. Perche'?
+
+A: Si tratta di una caratteristica di firefox: il tasto ESC termina
+   l'operazione corrente.
+   Soluzione semplica: non schiacciate ESC in Firefox.
+   Soluzione complessa: chiedete agli sviluppatori di Firefox di aggiungere
+   la configurazione della tastiera.
+
+
+Q: Spedire come utente F*EX e' facile, ma come posso
+   ricevere i file da altri utenti all'esterno?
+
+A: Registrali come tuoi "sotto-utenti" oppure crea un gruppo F*EX
+   con http://$HTTP_HOST$/fuc
+
+
+Q: Qualche volta posso scaricare un file piu' di una volta,
+   specialmente quando ripeto l'operazione velocemente.
+   La funziona di autodelete e' poco affidabile?
+
+A: Il server F*EX rende disponibile il file scaricato ancora per un
+   periodo di 1 minuto. Questo e' necessario per evitare che alcuni
+   "download managers" piuttosto stupidi diano errore in quanto
+   richiedono il file parecchie volte di seguito.
+
+A: Il vostro fexmaster ha impostato la variabile AUTODELETE=DELAY
+   come default, il che significa che il processo di
+   autocancellazione e' eseguita una volta al giorno.
+
+A: Certi utenti (usate i sorgenti!!!) possono impostare il flag
+   "non cancellare dopo il download".
+
+
+Q: La finestra temporale prima che il file sia cancellato e' troppo
+   stretta per me, ho bisogno di allargarla. Come posso fare?
+
+A: Usate fexsend, chiedete al vostro fexmaster oppure leggete il
+   codice sorgente :-)
+
+
+Q: Durante il download di un file con Internet Explorer
+   mi dice "Non posso aprire il sito Internet". Cosa posso fare?
+
+A: Usate Firefox o qualsiasi altro browser WEB compatibile con Internet,
+   dato che Internet Explorer non lo e'. Questo e' uno dei tanti bug di
+   Internet Explorer.
+
+
+
+
+Domande Amministrative:
+=======================
+
+Q: Non posso installare un server web come fexsrv perche'
+   non ho i permessi di root. Esiste una pura versione CGI
+   di F*EX eseguibile con un web server Apache ?
+
+A: F*EX e' rigidamente vincolato a fexsrv per diverse ragioni (performance,
+   limite dimensione file, concetto di sessione, etc) e non puo' essere
+   eseguito come una CGI sotto apache.
+   Potete dare un'occhiata a
+   http://gpl.univ-avignon.fr/filez/
+   http://freshmeat.net/projects/eventh/
+   http://www.schaarwaechter.de/sp/projekte/dateiaustausch.html (Solo in Tedesco!)
+   il quale implementa uno scambio file come pura CGI, ma ha il limite dei 2 GB.
+
+
+Q: F*EX non funziona per nulla!
+   Non mi posso connettere con il mio browser web!
+
+A: Controllate il routing, le impostazioni del firewall e di ipfilters.
+   Controllate anche che il vostro xinetd sia collegato con il
+   wrapper-tcp e sia configurato correttamente (hosts.allow).
+   F*EX necessita della porta 80/tcp (HTTP) e opzionalmente
+   della 443/tcp (HTTPS).
+
+
+Q: F*EX e' troppo complicato!
+   Mi serve qualcosa di piu' semplice.
+
+A: Provate http://www.home.unix-ag.org/simon/woof.html
+
+
+Q: Come posso integrare F*EX nell'ambiente di gestione
+   dell'utente esistente nel mio sito?
+
+A: F*EX ha diversi moduli di autenticazione:
+   locale, RADIUS, LDAP, mailman e POP
+   Per gli ultimi 4 si prega di contattare l'autore
+   framstag@rus.uni-stuttgart.de
+
+
+Q: Vorrei che i miei utenti locali usassero
+   F*EX automaticamente. Come??
+
+A: Lasciate che si registrino da soli con http://yourfexserver/fur
+   Dovete editare il file lib/fex.ph ed impostare (esempio):
+   @local_hosts = qw(127.0.0.1 10.10.100.0-10.10.255.255);
+   @local_domains = qw(flupp.org ulm.sub.net);
+   (Ovviamente dovete iunserire i vostri dati reali!)
+
+
+Q: Ho bisogno di maggior sicurezza! Come posso abilitare HTTPS??
+
+A: Leggete la documentazione doc/SSL ed anche cercate "fop_auth" in doc/concept
+
+
+Q: Ho bisogno di un look aziendale.
+   Come posso configurare F*EX per questo?
+
+A: Potete Guardare la variabile @H1_extra nel file fex.ph ed aggiungere
+   codice HTML al file htdocs/header.html
+
+A: Guardate il file htdocs/fup_template.html, modificatelo secondo i vostri
+   bisogni ed utilizzatelo come start-page.
+
+
+Q: F*EX e' troppo complicato per i miei utenti.
+   Ho bisogno di una form semplificata.
+
+A: Guardate il file htdocs/fup_template.html
+
+
+Q: Vorrei che le e-mail BCC indirizzate all'amministratore
+   fex fossero spedite ad altro indirizzo.
+
+A: Usate procmail o scrivete OTHERADDRESS in /home/fex/.forward
+
+
+Q: Posso avere una versione localizzata
+   nella mia lingua??
+
+A: Con il vostro aiuto, si'. Per favore contattate l'autore a
+   framstag@rus.uni-stuttgart.de
+
+
+Domande varie:
+==============
+
+Q: F*EX e' ottimo! Posso lavorare con
+   il team di sviluppo?
+   Che cosa c'e' bisogno di fare?
+
+A: Contattate l'autore framstag@rus.uni-stuttgart.de
+   Funzionalita' richieste:
+
+     - Un plug-in F*EX per thunderbird o outlook
+     - Supporto in altre lingue

F*EX - Frams' Fast File EXchange

+
+

+

+F*EX (Frams' Fast File EXchange) e' un servizio per spedire grossi (grandi, enormi, giganti, ...) file da un utente A ad un utente B.
+

+Il mittente carica il file nel server F*EX usando una
+form WWW di carico mentre al destinatario viene recapitata una e-mail di notifica con un link per effettuare il download. 
+

+
+Direte:
+

+  Per quale motivo ho bisogno di un altro servizio per effettuare il trasferimento dei files?!

+  Per questo ho gia' la posta elettronica(e-mail), l'ftp, l'ssh ed anche il comando sendfile!
+

+

+Io dico:
+

+  Nonostante tutto hai bisogno di F*EX :-)
+

+

+  
+Supponiamo, per esempio, che tu voglia spedire ai tuoi amici il video delle tue ultime vacanze (1 GB). Hai le seguenti possibilita' (e problemi):

+
+
    
+  
  • spedire un DVD con il servizio postale
    
+      Fuori discussione - viviamo nell'anno
+      <> 
+      dopo l'invenzione di Internet!
+      Spedire supporti hardware e' da trogloditi.
+      
    
+  
  • usare la posta elettronica (e-mail)
    
+      Gran parte dei server di posta elettronica hanno un limite di 10 MB per ognuna delle e-mail e la quota totale e' di meno di 100 MB per utente.
+      
    
+  
  • uucp
    
+      Perche' non usare la scrittura cuneiforme su una lastra di pietra?
+      
    
+  
  • ssh
    
+      Avete la password dei vostri amici oppure siete disposti a dargli la vostra?
+      - solo per trasferire un file?
+      
    
+  
  • ftp
    
+      
      
+        
    • Quale server ftp usare?
+        
    • Quale utente usare, quale password?
+        
    • Non vi dispiace mandare password e files non crittografati su Internet (insicura per definizione)?
+        
    • Il vostro proxy supporta l'ftp passivo?
+        
    • In caso di ftp anonimo:
+          
        
+            
      • Permette di caricare file da 1 GB?
+            
      • Permette di cancellare il file caricato subito dopo?
+            
      • Chi altri puo' fare il download del vostro file?
+            
      • Chi altri puo' cancellare il vostro file?
+            
      • Dovete mandare ai vostri amici il link per lo scarico, loro devono informarvi di avere effettuato il download del file e voi dovete cancellarlo subito dopo.
        
+                In poche parole: una rottura di scatole.
+          
      
+      
    
+      
    
+  
  • http
    
+      
      
+        
    • Non esiste un programma di default - deve essere costruito.
+        
    • Non esiste l'auto-notifica.
+        
    • Non esiste l'auto-cancellazione.
+        
    • Pochissimi server HTTP possono trattare file piu' grandi di 2 GB.
+      
    
+      
    
+  
  • sendfile
    
+      
      
+        
    • Avete UNIX ed avete sendfile installato?
+        
    • Il vostro destinatario ha UNIX ed ha sendfile installato?
+        
    • Sicuri che ne' voi, ne' il vostro destinatario avete un firewall che blocca la porta 487?
+      
    
+      
    
+  
  • servizi commerciali come DropLoad, ALLPeers, YouSendIt, eccetera
    
+      
      
+        
    • Quale limite hanno (gran parte: < 2 GB)?
+        
    • Cosa dire di sicurezza e privacy: i vostri file saranno salvi e sicuri?
+        
    • Sono basati su servizi open source o su proprietari?
+        
    • Sono accessibili con qualsiasi browser oppure hanno bisogno di java, active-X, flash o qualche altro plug-in?
+        
    • Sopravviveranno per piu' di qualche mese?
      
+           (Per esempio servizi quali DropLoad, ALLPeers e drop.io hanno gia' terminato la loro attivita')
+

+F*EX.
+

+
Principali caratteristiche di F*EX

+

+
    
+  
  • trasferimento file di dimensioni virtualmente illimitate.
+  
  • il destinatario ed il mittente hanno bisogno solo di un programma di posta elettronica e di un browser WEB 
+      di qualsiasi tipo: non devono installare nulla.
+  
  • funzioni RESEND e REGET per riprendere l'esecuzione dopo un blocco della connessione all'ultimo byte.
+  
  • auto-notifica del destinatario.
+  
  • auto-cancellazione dopo il download.
+  
  • auto-cancellazione dopo un periodo di 5 giorni (per default).
+  
  • gli utenti "full" possono creare "sottoutenti" o utenti "limitati" i quali possono spedire solo a questo server.
+  
  • gli utenti "full" possono creare gruppi in analogia a quanto succede per le liste di distribuzione, solo che viene fatto per i file.
+  
  • manutenzione semplice: non e' necessario l'intervento dell'amministratore per la creazione di nuovi utenti F*EX.
+  
  • l'invio di file a piu' destinatari occupa nel server solo lo spazio di una sola spedizione.
+  
  • F*EX e' un web-service di tipo HTTP e non ha bisogno di "tunnels" nel firewall.
+  
  • sono supportati anche i flussi (stream).
+  
  • per gli utenti che conoscono UNIX, ci sono gli script-shell fexsend e fexget
+      che evitano l'uso di un browser-WEB.
+  
  • i protocolli ed il codice sorgente sono liberamente disponibili (Perl Artistic).
+

+
+
Parliamo di SEX

+F*EX ha un compagno: Stream EXchange (SEX).

+Potete immaginare  che SEX sia una specie di lunga pipe UNIX con un relay in mezzo.
+Questo servizio puo' essere utilizzato per il travaso di dati da un utente A ad un utente B quando A e B non possono stabilire una connessione diretta ma entrambi possono stabilire una connessione HTTP con il server SEX. Per una completa integrazione con i tool di concatenazione dei comandi di UNIX, ci sono gli script-shell sexsend and sexget.
+

+L'autenticazione e' la stessa utilizzata da F*EX.

+F*EX (File EXchange)
+e' un servizio per spedire grossi (grandi, enormi, giganti, ...) file.
+

+Il mittente (tu) carica il file nel server F*EX ed automaticamente il destinatario si vede recapitare
+una e-mail di notifica con il link per effettuare il download.

+Dopo il download o dopo $keep_default giorni, il server cancella il file.
+F*EX non e' un sistema di archiviazione!
+

+Guardate anche domande e risposte (Q&A).
+

+

+  $ENV{SERVER_ADMIN}

+

+EOD
+
+$info_2 = <

+Dopo il caricamento del file vedrete una barra di avanzamento 
+(bisogna avere javascript abilitato ed i popup abilitati).
+

+NOTA: Parte dei browser-WEB non possono caricare file > 2 GB!

+Se il tuo file e' piu' grande devi usare un client F*EX particolare.

+Hai bisogno anche di un tool per recuperare i download interrotti. Il tuo browser-WEB non puo' farlo.
+

+Attenzione: alcuni proxy HTTP come privoxy ritardano lo stattttto della barra di avanzamento!

+Potresti voler disabilitare il proxying $ENV{SERVER_NAME} se ti capita di incorrere in questo problema.
+

+Utenti Firefox: non digitare [ESC] perche' questo interrompera' il caricamento!

+
+Meta preguntas:
+===============
+
+P: ¿Por qué el nombre de F*EX y no uno más corto?
+
+R: En el momento de la publicación había ya un programa llamado "FEX" activo 
+   (más viejo) freshmeat.net.
+
+
+P: ¿Por qué no emplear un servicio comercial
+   DropLoad, ALLPeers, YouSendIt, etc?
+   
+R: Tienen un límite de 2GB incluso ó menos.
+   Su estado de privacidad y seguridad es desconocido.
+   No están basados en software abierto.
+   No existe ningún cliente UNIX (CLI) para ellos.
+   Necesitan java, active-X, flash u otros plugins endemeniados.
+   Se desconoce cuanto durarán - DropLoad y ALLPeers
+   ha finalizado sus asuntos.
+
+
+P: ¿Por qu el camello como logo?
+
+R: El logo fue inspirado por el camello de Perl, pero est basado en un Steiff
+   el camello de peluche, que correo con con nosotros on nuestro tamdem de 
+   carrelas.  El logo fue dibujado por Beate.
+
+
+P: ¿Dónde puedo conseguir los fuentes de F*EX?
+
+R: http://fex.rus.uni-stuttgart.de/fex.html
+
+
+P: ¿Que hace falta para instalar F*EX?
+
+R: Un servidor UNIX con una entrega DNS y smtp para correo saliendo.
+   Y hace falta estar root en este ordenador.
+
+
+P: ¿Que es DNS y smtp?
+
+R: Que no instale F*EX. Es allende de su horizonte.
+
+
+P: ¿Quién es el autor?
+
+A: Ulli Horlacher <framstag@rus.uni-stuttgart.de>
+
+
+P: ¿Qué licencia tiene F*EX?
+
+R: Software libre Perl Artistic, vea http://fex.rus.uni-stuttgart.de/doc/Licence
+
+
+P: ¿Hay una lista de correo de F*EX?
+
+A: https://listserv.uni-stuttgart.de/mailman/listinfo/fex
+
+
+P: ¿Dónde puede conseguir apoyo comercial para F*EX?
+
+R: Contacte con fex@nepustil.net http://www.nepustil.net/
+
+
+P: ¡Tengo más/otras preguntas de las que aparecen en este documento!
+
+R: Pregunte al autor <framstag@rus.uni-stuttgart.de>
+
+
+Preguntas de los usuarios:
+==========================
+
+P: ¿Qué es el "auth-ID"?
+
+R: El auth-ID es una identificación interna que autentica al usuario.
+   La primera vez es generado por el administrador o por el proceso de registro
+   automático y pude modificarlo más tarde. Piense en él como
+   una especie de clave poco segura.
+
+
+P: ¿Puedo usar un proxy HTTP?
+
+R: Sí
+
+
+P: He subido un fichero ENORME pero me he confundido al escribir la dirección 
+   de correo electrónico del destinatario.
+   Acabo de recibir un correo de error de rebote. 
+   ¿Tengo que volver a subir el fichero ENORME?
+
+R: No, no es necesario. Puede redirigir el fichero con
+   http://$HTTP_HOST$/rup
+
+
+P: He subido un fichero ENORME pero olvidé poner a un destinatario.
+   ¿Tengo que volver a subir el fichero ENORME?
+
+R: No, no es necesario. Puede reenviar una copia del fichero con
+   http://$HTTP_HOST$/foc
+
+
+P: ¿¡No puede subir ficheros > 2 GB con mi navegador web!?
+
+R: Todos los navegadores web que conozco tienen errores en su implementación
+   de HTML-FORM. El límite en la mayoría es de 2 GB, algunas veces 4 GB.
+   Tiene que usar un cliente especial de F*EX para subir ficheros > 2 GB, vea
+   http://$HTTP_HOST$/tools.html
+
+
+P: Mi descarga abortó antes de que acabara. ¿Puedo continuar la descarga?
+
+R: F*EX soporta la continuación de la descarga, pero su cliente debe soportar
+   también esta característica. Firefox, por ejemplo, no tiene esta 
+   característica HTTP, necesita otro cliente como opera, wget o fexget
+
+
+P: Mi subida abortó antes de que finalizara. ¿Puedo continuar la subida?
+
+R: F*EX soporta la continuación de la subida, pero su cliente también debe 
+   soportarla. Ningún navegador web tiene esta característica, necesita un 
+   cliente de F*EX especial como fexsend, schwuppdiwupp o F*IX
+   Vea http://$HTTP_HOST$/tools.html
+
+
+P: Cuando pulso [ESC] en firefox la subida se cancela. ¿Por qué?
+
+R: Esta es una característica de firefox: ESC finaliza la operación en curso.
+   Solución sencilla: no pulse ESC en Firefox
+   Solución compleja: pida a los desarrolladores de Firefox que añadan una 
+                      configuración del teclado
+
+
+P: Enviar como usario F*EX es fácil, pero ¿como pueden recibirse fichero de 
+   otros desde fuera?
+
+R: Registrelos como su subusuarios o cre un grupo F*EX
+
+
+P: A veces puedo descargar un fichero más de una vez, especialmente cuando
+   lo repito rápidamente. ¿Tiene errores la caracter de autoborrado?
+
+R: El servidor F*EX tiene un tiempo de gracia de 1 minuto tras la primera
+   descarga con exito durante el cual el fichero está disponible todavía.  
+   Este es necesario porque algunos "administradores de descargas" estúpidos 
+   solicitan el fichero varias al mismo tiempo.  De otra manera, informan al 
+   usuario de un error.
+
+R: Su fexmaster ha establecido AUTODELETE=DELAY por defecto, lo que significa 
+   que el proceso de limpieza del autoborrado se ejecuta una vez al día
+
+R: Los usuario normales (use los fuentes, Luke!) pueden establecer una bandera
+   de "no borrar tras la descarga"
+
+
+P: El tiempo por defecto para mantener el fichero en el sistema es desmasiado 
+   corto para mí, necesito más. ¿Cómo puedo cambiarlo?
+
+R: Use fexsend, pregunte a su fexmaster o lea el código fuente
+
+
+P: No puede descargar ficheros con Internet Explorer, me dice "No puedo
+   abrir el sistio de Internet". ¿Qué debería hacer?
+
+R: Use Firefox o cualquier otro navegador web compatible con Internet, puesto 
+   que Internet Explorer no lo es. Este es uno de los muchos errores de 
+   Internet Explorer.
+
+
+Preguntas del administrador:
+============================
+
+P: No puedo instalar un servidor web como fexsrv, porque no tengo permisos
+   de root. ¿Existe una versión CGI pura de F*EX que funcione con un
+   servidor web apache?
+
+R: F*EX está íntimamente unido a fexsrv por varias razones (prestaciones,
+   limitación en el tamaño del fichero, el concepto de sesión, etc.) y no 
+   puede ejecutarse como CGI desde apache.
+   Pero puede echar un vistazo a
+   
+   http://gpl.univ-avignon.fr/filez/
+   http://freshmeat.net/projects/eventh/
+
+   que implementa un intercambio de ficheros con CGIs puros, pero ambos están 
+   limitados a 2 GB.
+   
+
+P: ¡F*EX no funciona en absoluto! 
+   ¡No puedo conectarme a él con mi navegador web!
+
+R: Compruebe el encaminamiento, los filtros IP y la configuración del 
+   cortafuegos. Compruebe también si su xinetd está enlazado con tcp-wrapper 
+   y configúrelo correctamente (hosts.allow).
+
+   F*EX necesita el puerto 80/tcp (HTTP) y opcionalmente el puerto 443/tcp
+   (HTTPS).
+
+
+P: ¡F*EX es muy complicado! Necesito algo más sencillo.
+
+R: Pruebe http://www.home.unix-ag.org/simon/woof.html
+
+
+P: ¿Como puedo integrar F*EX la administración de usuario existente de mi 
+   sitio?
+
+R: F*EX tiene varios módulos de autenticación:
+   local, RADIUS, LDAP, mailman y POP
+   Para los últimos 4 póngase en contacto con el autor por favor.
+   
+
+P: Quiero que todos mis usuarios locales use F*EX automáticamente. 
+   ¿Cómo puedo hacerlo?
+
+R: Déjelos autoregistrarse.
+   Tiene que editar el fichero lib/fex.ph y establecer (ejemplo):
+
+   @local_hosts = qw(127.0.0.1 10.10.100.0-10.10.255.255);
+   @local_domains = qw(flupp.org ulm.sub.net);
+
+   ¡Desde luego tiene que añadir su hosts/redes locales reales!
+
+
+P: ¡Necesito más seguridad! ¿Cómo activo HTTPS?
+
+R: Lea doc/SSL y mire busque también "fop_auth" e doc/concept
+
+
+P: ¡Necesito que tenga una imagen corporativa. ¿Como configuro F*EX para que 
+   la tenga?
+
+R: Vea la variable @H1_extra en fex.ph y puede añadir htdocs/header.html
+
+R: Vea fup_template.html, modifíquela según sus necesidades y usela como 
+   página de inicio
+
+
+Otras preguntas:
+================
+
+P: ¡F*EX es estupendo! ¿Puedo unirme al equipo de desarrollo? 
+   ¿Qué hay que hacer?
+
+R: Contacte con el autor
+
+   Características no presente:
+
+   - otro cliente de subida que se integre mejor en Windows
+     arrastrar y soltar, libro de direcciones de Outlook, etc.

F*EX - Frams' Fast File EXchange

+
+

+

+F*EX (Frams' Fast File EXchange) es un servicio para enviar ficheros (grandes, enormes,
+gigantes, ...) de un usuario A a otro B.
+

+El remitente sube el fichero al servidor F*EX usando
+el formulario de subida WWW y el destinatario
+automáticamente recibe una notifiación por correo electrónico con la URL de desacarga.
+

+
+Usted dirá:
+

+  ¡¿Por qué necesito de otro servicio de transferencia de ficheros?!

+  ¡Tengo el correo electrónico, ftp, ssh e incluso sendfile!
+

+

+Yo le respondo:
+

+  Aun así necesita F*EX :-)
+

+

+  
+Por ejemplo, quiere enviar a un amigo su último video de las vacaciones (1 GB).
+Tiene las siguientes posibilidades (y problemas):

+
+
    
+  
  • enviar un DVD por correo postal
    
+      Sin comentarios - ¡vivimos en el año
+      <> 
+      tras la invención de internet!
+      Enviar DVDs/CDs es para los abuelos.
+      
    
+  
  • usando el correo electrónico
    
+      La mayoría de los servidores de correo tienen una límite de 10 MB por mensaje de correo electrónico
+      y una cuota de almacenamiento de uno 100 MB por usuario e incluso menos.

    • ¿No le importa enviar contraseñas sin cifrar y ficheros a través de internet que no es seguro?
+        
    • ¿Su proxy soporta ftp pasivo?
+        
    • En caso de usar ftp anónimo:

+            
      • ¿Permite subi 1 GB?
+

+            
      • ¿Quién más puede descargar su fichero?
+            
      • ¿Quién más puede borrar su fichero?
+            
      • Tiene que enviarle a su amigo la URL de descarga, él tiene que 
+                informarle de que la descarga ha finalizado sin problemas y
+                tiene que borrar el fichero después.

+        
    • ¿Ni usted ni su destinatario tiene un cortafuegos que bloquee el puerto 487?
+      
    
+      
    
+  
  • servicios comerciales como DropLoad, ALLPeers, YouSendIt, etc.
    
+      
      
+        
    • ¿Qué limite tienen (la mayoría: < 2 GB)?
+        
    • ¿Qué pasa con la seguridad y la privacidad: estarán sus ficheros a salvo?
+        
    • ¿Están basados en software abierto o propietario?
+        
    • ¿Son accesible con cualquier navegador o necesita java, active-X, flash u otro plugins?
+        
    • ¿Sobrevirá más de unos cuantos meses?
      
+           (DropLoad y ALLPeers ya han finalizado su actividad)
+      
    
+      
    
+

+

+Si ha contestado sólo una vez "no" a las preguntas anteriores, entonces necesita
+F*EX.
+

+
Principales características de F*EX

+

+
    
+  
  • transferencia de ficheros de tamaño virtualmente ilimitado
+  
  • el destinatario y el remitente solo necesitan un programa de correo electrónico y un navegador web -
+      de cualquier tipo, no necesitan instalar ningún software
+  
  • RESEND y REGET para continuar las descargas interrumpidas por fallos en el enlace
+  
  • autonotificación al destinatario
+  
  • autoborrado tras la descarga
+  
  • autoborrado tras la fecha de expiración (por defecto: 5 días)
+  
  • los usuarios normales pueden crear subusuarios, que pueden enviar solo al usuario normal que lo definió
+  
  • los usuarios normales puede crear grupos, una anología de las listas de correo, pero para ficheros
+  
  • sin mantenimiento: no es necesaria la intervención del administrador más allá de crear la cuentas en F*EX
+  
  • para enviar a múltiples destinatarios solo es necesario subir el fichero una vez
+  
  • F*EX es un servicio web HTTP y no necesita que se creen túneles en los cortafuegos
+  
  • también soporta streams
+  
  • los usuarios UNIX reales, puede usar los programas para el shell fexsend y fexget para
+      evitar el uso del navegador web
+  
  • el protocolo y código fuente están disponibles (Perl Artistic)
+

+
+
Hablemos de SEX

+F*EX tiene un acompañante: Stream EXchange (SEX).

+Puede imaginar SEX como si fueran tubería de UNIX a través de la red con un relay en medio.
+Esto puede ser útil para entubar datos del usuario A a otro B, donde A y B no pueden
+establecer una conexión directa, per ambos puede conectar por HTTP a servidor SEX.
+Las herramientas del shell sexsend y sexget permiten integrarlo fácilmente entre

+F*EX (File EXchange)
+es un servicio para enviar ficheros (grandes, enormes, gigantes, ...).
+

+El remitente (usted) sube el fichero al servidor F*EX y el destinatario recibe automáticamente
+una notificación por correo electrónico con una URL de descarga.

+Tras la descarga o tras $keep_default días el servidor borra el fichero.
+¡F*EX no es un archivador!
+

+Vea también preguntas y respuestas.
+

+

+  $ENV{SERVER_ADMIN}

+

+EOD
+
+$info_2 = <

+Tras pulsar el botón de enviar verá una barra de progreso de la subida
+(si tiene javascript activado y permite las ventanas emergentes)
+

+NOTE: ¡La mayoría de los navegadores web no pueden subir ficheros > 2 GB!

+Si su fichero es más grande tiene que usar un cliente de F*EX especial.

+También necesita uno para poder continuar con una subida interrumpida. Su navegador no puede hacerlo.
+

+Aviso: ¡algunos proxys HTTP como privoy retrasan la barra de progreso de la subida!

+Quizá quiera desabilitar el proxy para $ENV{SERVER_NAME} si se encuentra con problemas.
+

+Usuarios de firefox: ¡no pulse [ESC] porque aborta la subida!
