[Pkg-citadel-devel] Bug#862297: Install fails if SMTP server is running on port 25, rendering console unuseable

[John Goerzen]

Package: citadel-server
Version: 902-3
Severity: grave

Hi,

I installed citadel-server (but not citadel-mta).  I will note that citadel-server
does not conflict with mail-transport-agent (citadel-mta does, but not citadel server).

I attempted to install citadel-server on a system that already had an MTA installed,
using the same command as I showed in #862296.  When doing so, my console -- and every
ssh session to root -- became nearly unuseable as it was flooded with continuous complaints
about the port 25 already being in use, at such a rate that I couldn't see anything I
was typing.  I was eventually able to blindly type "killall citserver" to get rid of
this problem.

The messages looked like this:

Broadcast message from systemd-journald at sid (Wed 2017-05-10 14:54:20 CDT):

citserver[16663]: WX Modules: Citadel had trouble on starting up. We couldn't bind all ports you configured to be provided by citadel server.
                This means, citadel won't be the service provider for a specific service you configured it to.

                                                                                                              If you don't want citadel to provide these services, turn them off in WebCit via: "Admin->System Preferences->Network".

                                                                                                       The failed ports and sockets are: TCP port 0.0.0.0:25: (SMTP-MTA) 

                                           If you want citadel to provide you with that functionality, check the output of "netstat -lnp" on linux Servers or "netstat -na" on *BSD and stop the program that binds these ports.
                                                                                                   You should eventually remove  their initscripts in /etc/init.d so that you won't get this trouble once more.
                                                                                  After that goto "Administration -> Shutdown Citadel" to make Citadel restart & retry to bind this port.


                                                           To make both ways actualy take place restart the citserver with "sendcommand down"

               The errors returned by the system were:
                                                      Can't bind: Address already in use

                                                                                        You can recheck the above if you follow this faq item:
