use tcpdump -i interface_name
IE:
tcpdump -i eth0
also, I noticed that tcpdump is not installed by default, it is on the cd
distro/ downloaded distro

Sometimes the " /etc/resolv.conf" file needs to be edited to include the
DNS servers that your ISP gave you. If this is not added you probably
won't see any thing from the Internet. Below is an example of my
/etc/resolv.conf file:
search emad
nameserver 207.67.165.4
nameserver 209.203.108.249
nameserver 207.16.23.254
nameserver 192.168.0.246
nameserver 192.168.0.1
List the ones given by your ISP first
