Or better yet just use snort in it's packet logger mode and do something

snort -b -l /var/wherever

You can even add BPF style filters just like in tcpdump and do something

snort -b -l /var/wherever 'net'

Which will grab anything to or from that network.  You can also grab a whole
BPF file with the -F if you want to make a really complicated filter -
perfect for replacing Shadow.
