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

Fri Jul 12 04:22:15 EDT 2013

FIXED!

Thank you Amrit!  Although I had a handful of hosts in my /etc/hosts file,
I seemingly hadn't correctly set up resolv.conf (although I don't
understand why 127.0.0.1 didn't work).  I'm sure I'd done this the first
time around, but since I did a complete re-install of the box to try and
get this working, I had literally installed ircd-hybrid as the first thing
I did, and hadn't checked the basics (I case of making the machine run
before it could walk, perhaps.. although my first attempt definitely did
have DNS working, but we'll never know why that didn't work).

The give-away, now that it's working is that after the previously stalled
"No Ident response" line, I now get
09:16 !copstick4 *** No Ident response
09:16 !copstick4 *** Found your hostname
09:16 -!- Welcome to the debian Internet Relay Chat Network Dave_

...showing that hostname lookup was what was halting it.  (For the record
Amrit, I couldn't find an option in the config to disable hostname lookups).

This is all working with a very basic stock config file, and without SSL
compiled in... now that is working I will start piling on the more complex
stuff when I get home from work tonight.

Finally, for any newbies googling this, the complete fix was just a case of
adding:
        dns-nameservers 10.9.2.99
...to the eth0 section of my /etc/network/interfaces file and rebooting, so
that /etc/resolv.conf got the right nameserver written to it when
networking came up.

Thanks everyone for your help and suggestions.  I'm almost embarrassed at
what a basic error I had made.  I'll go back to building up a more complex
config later on.

Cheers,
--Dave
