Thanks for your response. Our network is 10.0.0.255. A machine with IP
192.168.1.251 shouldn't exist.
I think I should also check if any machine on the network is infected with
some virus or trojan.

To disable the error being logged by the kernel changing the following
echo 1 >/proc/sys/net/ipv4/icmp_ignore_bogus_error_responses
From what I can tell, these aren't usually a result of an attack (but
others will probably have more information.)
But things to check - Is this IP on your network? Could there be a
problem with that machine?

I'm getting the following entery in the message log every 5 mins:
kernel: 192.168.1.251 sent an invalid ICMP error to a broadcast.
I'm running Redhat Linux 9. Is it an attempt to hack into the system?
