Could you please tell *me* what "ICMP redirect" frames do ? I regularly
get the following message in my /var/log/messages file and I am not sure
what is causing them.
Jan 27 11:41:01 ns kernel: ICMP redirect from xxx.yy.zz.1
Jan 27 11:41:59 ns kernel: ICMP redirect from xxx.yy.zz.1
Jan 27 11:50:01 ns kernel: ICMP redirect from xxx.yy.zz.1
"ns" is our primary DNS name server and so gets alot of traffic from
inside and outside our LAN. We currently have 3 Class C networks running
on the same ethernet, with routing between them handled by the default
router (xxx.yy.zz.1). "ns" is handling name service for all three Class C
networks. I occasionally get the same message on other machines, but with
*much* less frequency...
Any suggestions ?
