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?

Subject: Is it hacking?

Hello everyone,

I'm getting the following entery in the message log every 5 mins:

kernel: sent an invalid ICMP error to a broadcast.

I'm running Redhat Linux 9. Is it an attempt to hack into the system?
Any advice?
