Ipwatchd is telling me about a conflict that I just do not understand. As far as I can tell, there is no conflict. Am I reading the message wrong?
It's a Xen machine with the following network interfaces:
- bridge 'eth0' (00:25:90:06:db:1c), containing peth0 (00:25:90:06:db:1c, same address): 89.188.x.y
- eth1 (00:25:90:06:db:1d): 10.0.0.2
The fact that the bridge is called eth0 and the physical Ethernet is peth0 is a Xen 4.0 idiosyncrasy.
The ipwatchd message is:
MAC address 0:25:90:6:db:1c causes IP conflict with address 10.0.0.2 set on interface eth1 - passive mode - reply not sent
The MAC mentioned is that of eth0 (peth0). The 10.0.0.2 address is of 00:25:90:06:db:1d. 00:25:90:06:db:1c doesn't have 10.0.0.2 and is not conflicting.
So, what does the message mean?
