[cups.general] Connection to CUPS server failed

[Christopher Singley]

Greetings.

I've newly installed Ubuntu 5.10 "Breezy Badger", running kernel  
v2.6.12-10, and I seem to have done something bad to CUPS.  I cannot  
connect to the server via the web interface on port 631, or via the KDE  
system settings print admin (i.e. the connection times out in either case).

I can't figure out why this should be the case; inspecting the logs isn't  
proving informative.  Searching the web hasn't turned up much applicable,  
and I've exhausted my limited CUPS troubleshooting skills.  Can anyone  
give me some clues how to get connected to CUPS?
