It means that two NICs are reporting the same IP address. Sometimes this is hard to track done. I was running a local DNS server. I ran nslint over the zone files and found the problem. I don't have my notes. But I'll bet that 192.168.0.202 is assigned to two different machines. One has the MAC address 00:60:08:a6:0e:14. The other has 00:60:08:a6:06:fe. -- Dan Langille The FreeBSD Diary http://www.FreeBSDDiary.com/freebsd To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
