tcpdump

The tcpdump command can be used to gather the same data in a much less user friendly manner.

Start tcpdump using the following command:

/usr/sbin/tcpdump –s –l 256 –x –X port 26542 | tee tcpdump.log

The tcpdump.log file contains similar information as described for ethereal except that there is no color

highlighting, making it necessary to search for the string HTTP to determine where each of the different

message types begins.
