Monitoring application traffic

[Curious]

Hi,

I have a client application, that connects to a server on some other
unknown pc. Now, I would like to monitor the client application to
check what commands are being communicated between the two
applications, inorder to create a new personal client application.

Does their exist some application that can monitor data that is being
transmitted by a particular application.


Thanks in Advance

Can you modify the client app?

If not you will need a sniffer. Dont know if you can do this from the
framework, I bet that at least some p/invoke is needed.

take a look at codeproject.com and/or gotdotnet.com you may find there code
for this.
