Help with Netcat
Hi all,

I know my question is regarding Windows and not Linux, but I simply need people who know Netcat pretty well and I'm guessing here is a good place for that. So on with my question.

I'm doing some research, and I was playing around with netcat on a WinXP VM but I can't seem to get something.

I tried this command:

nc -l -p 80 -e "c:\notepad.exe"
(I copied notepad.exe to c:\ folder)

But what happens is simply that netcat closes and does nothing. It does connect, because if I leave the command without the "-e" parameter like this:

nc -l -p 80

It does show me an output. But when I add the "-e" and any program (I tried cmd, and others) - nothing will execute, and netcat simply shuts down.

Any ideas?
Thanks,
Jonathan
