On a dual homed 3.4-RELEASE FreeBSD firewall I'm suddenly getting: "/kernel: arp: 00:c0:4f:68:71:8e is using my IP address 127.0.0.1!" The 2 internal cards macs are set as ether 00:d0:b7:85:bb:ce and 00:d0:b7:85:bd:84 I didn't think the localhost address could get loose on the network ? How do I find the offending box in a mixed Macintosh/Pc network of 60 systems, switches and network printers ? What method can I use to scan the network for MAC addresses mapped to IP addresses in hopes the system also has a regular IP address running ? Thanks, John.
