To disable the error being logged by the kernel changing the following line: 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?

Hello everyone, 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? Any advice? Thanks, AR _________________________________________________________________ Don't just search. Find.
