Hi, I just had a wierd 'problem' with arp over the weekend.
I noticed this line in /var/log/messages
Nov 21 13:37:12 foonly /kernel: arp: 10.0.0.1 moved
from 00:60:97:1f:18:ce to 00:20:35:e7:b5:bc
I have not done anything that would make this change, i.e.: change
the network card, add a new host to the network with ip 10.0.0.1
by mistake, issued any arp commands.
This is a dual homed host with two 3com 3c509's in it. netstat -i
still says:
ep0 1500 <Link> 00.60.97.3a.2f.80 9245953 10800 122177 1 0
ep1 1500 <Link> 00.60.97.1f.18.ce 62020 0 73826 1 0
which makes sense to me since both's mac start with 00.60.97, i.e.
they are from the same manufacturer.
but now arp -a reports:
foonly.scimitar.org (10.0.0.1) at 0:20:35:e7:b5:bc permanent
cr323989-a.yec1.on.wave.home.com (24.112.82.27) at 0:60:97:3a:2f:80 permanent
Is this a bug in arp. BTW I am using 2.2.1 with ipfw and natd with ep0
as the outside interface and ep1 as the inside interface.
Everything seems to still work fine though. And I have since changed
it back with arp -S, no problem. Any ideas?
Please send any replies by email.
