You need a tool such as tcpdump ( http://www.tcpdump.org )
or ethereal ( http://www.ethereal.com )

Ethereal relies on the libpcap libraries provided on the tcpdump site.

You'll need to run the commands as an administrative user (i.e. root).

You can also try ngrep ( http://ngrep.sourceforge.net ).

Run port scans with nmap. Only use nmap on/against machines you are authorised to do so! ( http://www.insecure.org/nmap/nmap_download.html )
