I didn't know exactly which forum to post this question. I thought this would be the most logical.

I am conducting a test of technical security controls for a client and I'm looking for the easiest way to do this. I mainly want to test their IDS and AV capabilities. This is not a comprehense test of their systems, just a part as you can see.

I would like your suggestions on programs that can spawn a remote command prompt outbound through a firewall via a specific port from a WinXP box. The delivery method is a non-problem. I will ensure the files gets on the system. Mainly I just need to have the shell get sent out of the firewall so i can connect to it.

Any thoughts would be appreciated. Simplicity is key here. As mentioned before this is not a comprehensive test, just a one off.
