Reply-To: Hi, I'm trying to figure out why my icmplogs are showing UDP connections whenever my system recieve email. The connections are on UDP port 512. I'm using sendmail from woody as my MTA. It makes no difference whether or not biff is installed. the log reads: Mar 21 21:16:37 sxe icmplogd: destination unreachable from localhost [127.0.0.1] any ideas about how to solve this one would be appreciated. Thanks. David
