[hybrid] Clients can't connect (register) on Ubuntu 12.04LTS system

Fri Jul 12 03:38:00 EDT 2013

Well, one of my reasons for posting was to try and get guidance on where I
could find more information to help diagnose the problem.  There is only
one log-file that I can see, in /var/log/ircd/ircd-hybrid.log, and all that
ever gives is a list of modules loading at startup, e.g. upon a re-start:

[2013/7/12 08.20] Server Terminating: received signal SIGTERM
[2013/7/12 08.20] Module m_kline.so [version: $Revision: 611 $] loaded at
0x7f706fe98000
[2013/7/12 08.20] Module m_accept.so [version: $Revision: 33 $] loaded at
0x7f706fc95000
*snip many other module loaded lines*
[2013/7/12 08.20] Module m_squit.so [version: $Revision: 33 $] loaded at
0x7f7066fbc000
[2013/7/12 08.20] Server Ready

...ending on Server Ready.  It doesn't give any config errors, and doesn't
log any client connection attempts.  I have  "log_level = L_DEBUG;" in my
config, which I believe is the highest log-level.  If you can point me to a
way to get more diagnostics server-side as clients connect, I will happily
provide more info.

As I said in my original post, I do not have any server passwords set.  I
have made sure they are all commented out in the config file.  Also, as I
said, the identical config file results in a fully working server on
another machine, with clients able to connect straight away, with no
password.  I also don't think I follow your claim that the message "* Ident
response" = "I got problems"  ...the server I have been running for the
last 10 years always gave the "No Ident response" message during client
connections.  I don't believe that is any indication of critical problems.

As I mentioned originally, the same .deb package, and the same config file
installed on other Ubuntu 12.04LTS machines, work fine.  Clients connect
instantly, without problem.  I almost considered that it might be a problem
with the on-board LAN chipset on this PC, but ruled that out, since it
behaves identically when a client connect on the loopback interface on
127.0.0.1, thereby ruling out any network hardware.

So, as I say, if you can offer suggestions as to how I can get more
diagnostics on this, I'd be very grateful.  I've been trying to get this
up-and-running for 3 weeks now, and I'm completely out of ideas, or where I
might get help.

Cheers,
--Dave
