Hi everybody.

I 've got a message in my logfiles that I don't understand.
The ip-addresses are none that I'm to my knowing are associated with.
Wonder what it is or if it's anything to worry about.

odin.swedehost.com kernel log messages:
> icmp redirect from 65.104.98.146: 204.152.184.189 => 65.104.98.145

Checking up on the above Ip-addresses don't ring any bells ider.
Any clues ?

Regards
Geir Svalland.
