To avoid the unresolvable ip addr, either aviod DSN lookups altogether with -n , or include 'and not host xxx' where xxx is the ip address you want to skip: tcpdump -i eth0 not port 22 and not port 53 and not host xxx and not ip proto \\icmp Cheers, Terry. >Additionally there's a client popping up that doesn't havea resolvable >hostname how can I exclude it with tcpdump? > >Thanks in advance >Dan
Hi Thanks for the reply unforutnately I'm still getting the unresolvable error: tcpdump -n -i eth0 not port 22 and not port 53 and not host a72-246-55-1.deploy.akamaitechnologies.com and not ip proto \\icmp tcpdump: unknown host 'a72-246-55-1.deploy.akamaitechnologies.com' Any ideas? Thanks Dan
