I tracked this > down once before, but the heck if I can remember what the issue was. Hmm, I could have thought of that myself, except that I wasn't really expecting any traffic. Anyway, this is what I get (with the -e option so I can track it): 12:59:56.610694 0:4:ac:e4:b3:cf 0:2:44:17:f8:da arp 60: arp who-has wantadilla.lemis.com tell 0.0.0.0 12:59:56.610731 0:2:44:17:f8:da 0:4:ac:e4:b3:cf arp 60: arp reply wantadilla.lemis.com is-at 0:2:44:17:f8:da 13:00:51.611834 0:4:ac:e4:b3:cf 0:2:44:17:f8:da ip 146: 0.0.0.0.483635503 > wantadilla.lemis.com.nfs: 104 getattr [|nfs] (DF) This happens exactly once a minute. Looking at arp -a, I find that the Ethernet address 0:4:ac:e4:b3:cf is that of my machine echunga. On that machine, I find: rl0: flags=8843 mtu 1500 inet 192.109.197.82 netmask 0xffffff00 broadcast 192.109.197.255 inet6 fe80::200:21ff:feca:6ef1%rl0 prefixlen 64 scopeid 0x1 inet 192.109.197.137 netmask 0xffffffff broadcast 192.109.197.137 ether 00:00:21:ca:6e:f1 media: Ethernet autoselect (100baseTX ) status: active About the only thing unusual there is the alias address. There's no dhclient running, and this only started after the upgrade. I'm still puzzled.
