Well check this....
the message in my /var/log/messages is:
"kernel: arp: 192.168.2.34 moved from 00:13:8f:4c:1b:41 to 00:11:2f:0c:b1:0a on rl0"
So Hmm now that i am thinking of it again:
"server /kernel: arp 00:11:43:4a:8d:18 is using my IP address
This also looks like an IP conflict!! And it is not similar to mine, even if it can be the same...
Someone more experienced maybe can make this clear. To be honest i haven't seen the output you posted before...
Sorry for the inconvenience if i was wrong before..
