>Hi
Could someone please point out to me where I'm going wrong with the following:
tcpdump -i eth0 not port 22 and not port 53 not ip proto icmp
According to my man pages, you need to escape the icmp keyword thus (for C-shell)
tcpdump -i eth0 not port 22 and not port 53 not ip proto \\icmp
It works for me.
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:
Yeah, avoiding Deep Space network lookups is important. Ping times
out there are so long that it really makes transactions slow. I'd
stick with Domain Name Service, instead.
