I've been running cups happily on this box for a couple of years. It serves print requests from two other computers I have, one running Ubuntu (also running cups), and the other running WinXP.
With the upgrade to 1.2.1-r2 from 1.1.23, some probelms arose: 1) neither of the other machines can print through this server any more. 2) When either of the other machines is running at all, requests to print on this gentoo server lock up for just under 2 minutes before they get to printing. If I shut down the other machines, printing returns to normal locally. The error logs show a repeated error that doesn't ring a bell with me: E [15/Jul/2006:14:20:18 -0700] encrypt_client: Unable to encrypt connection from 64.166.164.53! The config files changed a bit on the upgrade, and I did my best. The last go 'round was through the web interface (once I got that working) so they've all been rewritten by cups. I cannot claim to understand them completely. Can anyone explain the @OWNER @SYSTEM things -- they sound good, but I'm not truly clear on exactly what they do in cups. I want to allow ports 631 (normal cups stuff from the Ubuntu machine) and 515 (LPD things for WinXP). I've looked at the config files, and nothing jumps out at me. The one mention of encryption is in the /auth section, which I don't use remotely anyway. Here's cupsd.conf: # Show general information in error_log.
