How do I sniff/monitor lan traffic?

[rbmcgee]

On my PC I have a program whose purpose is to send a command/instructions over the network to another computer on the lan. Software on that computer receives that command and executes accordingly. I would like to know the exact syntax of that command. I can't seem to understand what program I would use that could show me this command. Please advise.

If more feasible, I could monitor/sniff the receiving computer to see what commands/syntax is being received.

Thanks

You could use a linux distro like Knoppix or backtrack.

They are for advanced users though, and has almost no documentation. It is def not for the average user, and we will not give help for that here.

Just letting you know.

Good luck.
