Admin Q1: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?
Admin A1: 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

which implement a file exchange as pure CGIs, but with a 2 GB file size limit, which F*EX does not have.

Admin Q2:I have already a webserver (apache) running. How can I install F*EX in parallel?
Admin A2: 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.

Admin Q3:How do I install fexsrv with letsencrypt/TLS support?
Admin A3: See /home/fex/doc/letsencrypt
[↑ Questions]

Admin Q4:Ok, I have installed F*EX. What now?
Admin A4: 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/fup

... and join the F*EX mailing list! ☺

Admin Q5:What is /home/fex/bin/fac and /home/fex/cgi-bin/fac ?
Admin A5: 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

[↑ Questions]

Admin Q6:F*EX is not working at all! I cannot connect to it with my web browser!
Admin A6: 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).
/etc/xinetd.d/fex should not contain a line "only_from"
F*EX needs port 80/tcp for HTTP and optionally port 443/tcp for HTTPS.
Test the connection with: telnet YOURFEXSERVER 80

Admin Q7:What is the difference between all these user types (full, sub, group, external, ...)?

Admin Q8:How can I integrate F*EX in the existing user management at my site?

[↑ Questions]

Admin Q9:Can I make an alias address for an user?
Admin A9: 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

[↑ Questions]

Admin Q10:I want that all my local users can use F*EX. How?
Admin A10: 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!)
[↑ Questions]

Admin Q11:I want that external users can fex to my local users. How?
Admin A11: 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
