Many thanks to all who replied. Craig Russell and Ed Rolison both informed me of the evil nscd daemon that in addition to caching nameserver lookups also caches a copy of your arp table. Evil! Evil!! I ended up restarting nscd on the boxes, and then bringing the interface up and down to clear it all out. Thanks to Tim Chipman for suggesting that with command stacking I wouldn't need to pull out my LOM cables. Commands used: # /etc/init.d/nscd stop # /etc/init.d/nscd start # ifconifg hme0 down; ifconfig hme0 up Thanks again!
