Network packet capture / analysis: tcpdump

http://www.linuxjournal.com/content/tcpdump-fu

Example: capture anything sent to/from port 7500 on interface eth0 and dump it to a file


$ sudo /usr/sbin/tcpdump -w /tmp/tcpdump.out -s 0 -i eth0 port 7500

We can now use Wireshark to read the file and analyse the packets

To filter the packets based on, for example, a port; use an expression such as tcp.port == 1234
