From: <dondon () pacbell net> Someone on our network assigned an IP address to their own system without my knowledge. Using LANguard network scanner, the best I can tell is that it's a Linux box. The port-to-IP mapping table on our Asante switch doesn't see to work correctly. Any suggestions on tracing down that system that is associated with the IP is appreciated!Assign that IP to another box and wait to see who calls in for tech support because of the conflict.
A sysadmin I know used a Windows box on her all-Linux network for just that purpose; seems that Windows is *a lot* more contentious when fighting for a specific IP than Linux is. Mr. "oh, is that what those numbers I changed mean?" User showed up at her door within minutes.
