Greetings-
I have a newly installed Cent 4.4 machine where I have a primary IP address on eth0. I
also have several additional IP addresses on the same interface for virtual services.
I noticed this morning that I am unable to traceroute from all the ip addresses on the interface
eth0 to the primary address on eth0.
For example:
eth0 - 192.168.10.2
eth0:1 - 192.168.20.2
eth0:2 - 192.168.20.3
if I do traceroute -s 192.168.20.2 192.168.10.2 it works, but if I try
traceroute -s 192.168.20.3 192.168.10.2 it does not
Thought starters?
Thank you!

You may be running into a issue with "arp flux" and the virtual interface issue. I have read about some of the odd issues that can happen when more that one virtual interface is on the same subnet. A quick google of something like "linux arp flux problem" may give more info than my lame note here.
