[webmin-l] Off-Topic arpwatch & Flip Flopping NICs

[Cary R. <ca...@to...>]

Sorry to trouble this list, but I have looked for days trying to find 
info on my Flip Flopping NICs.

I have 2 NICs, eth0 & eth1 and have assigned them the IP addresses 
192.168.1.11 & 192.168.1.12 respectively. arpwatch reports that the 
IP address 192.168.1.12 hops back & forth between the 2 NICs.

Can anybody point me to a URL or book that can educate me on this 
"Flip Flop" thing ?


Here are a few of the reports that arpwatch sends me via email.
