Okay. > Today I'm running with my original resolv.conf. System has been up for > 1.5 hours. There hasn't been one UDP packet to port 137 logged.

The short answer: not simple. I gave you a vague idea of the types of tools used to try to figure that out to answer the questions: What ports are open, what processes are associated with those ports, what network traffic is passing through the box. > Mike Kershaw mentioned that a reboot is unnecessary.

Almost all text editors can be configured to leave a backup file, or configured not to. -- Chris -- Chris Knadle [EMAIL PROTECTED]
