man tcpdump will give you lots of documentation after you install it

tcpdump syntax for a specific host:
#tcpdump -i INTERFACE -n host MY_IP
tcpdump syntax for a specific port:
#tcpdump -i INTERFACE -n port PORT_NO
you might want to capture the traffic with tcpdump and look at it with Wireshark (formerly Ethereal).
#tcpdump -i INTERFACE -p -s 0 -w /path/x.trace.pcap port port_no
After finishing the trace load the pcap file into wireshark for a detailed analysis.
