-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This type of kernel message generally denotes one of two things, neither of which are usually nice. icmp-response bandwidth limiting is built into the kernel to lessen the effects of a ping flood, and are often the result of being flooded, but I have also noticed that message due to scans such as nmap. Either way, something happened that you will probably want to know about... I might recomend installing ipfilter and logging all traffic except your known/public services (and maybe even some of those ;).
