In servalan.mailinglist.fbsd-hackers you write: >> I've been sitting here watching ICMPs for kicks and I had an idea though I >> can't say as how useful it might be...

We could >call that program `tcpdump' :-) Or even have a program that listens on a raw socket for ICMP packets and syslog what it finds, and call it 'icmpinfo'. :-) (Yes there is such a program, and no, you don't need bpf to look at ICMP packets that are sent to your own system, opening a raw socket suffices. Shouldn't be too difficult to make icmpinfo work on FreeBSD...)
