Sorry if this seems like a dumb question, but you mentioned a "port to IP" table in your switch. Does your switch have a "port to MAC address table"? Or is that what you actually were referring to? If it has that, you can look at the ARP cache in the router for that segment and find the MAC associated with the IP address. Then you can compare the MAC to the table in the switch to find the port. -----Original Message----- From: dondon () pacbell net [mailto:dondon () pacbell net] Sent: Wednesday, April 30, 2003 6:40 PM To: security-basics () securityfocus com Subject: rogue IP address 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!
