icmplogd: destination unreachable?
Speaking of ICMP, I've noticed:
May 3 00:43:17 www icmplogd: destination unreachable from
[168.221.21.105]
messages appear in my log -- and repeat every 80 seconds. This happened
about a week ago, and started up again a few hours ago.
168.221.21.105 is a uu.net router I believe, but my machine seems to
cause the message because I noticed them continuing even after I
temporarily disconnected from the Internet. They stopped after a reboot
(UPS install). I don't know what caused them to start up again -- or
what they might mean.
I'm tempted to run "icmplogd -d", which won't log "destination
unreachable" messages. But will this prevent me from seeing any useful
security information re: ICMP?
Thanks for any help!
