How do I open a couple of ports?

[Kooldino]

I'd like to open two ports on my PC at work (so that they think I have some stupid monitoring programs open).

I just need to open them and make them "listen".

What's the safest/least taxing program I could run to accomplish this?

[Wombat]

Just start up some server with a login, and give it a non-standard port. I think the safest would probably be cygwin-ssh. You could also tell an FTP server to start up on whatever port.

I was thinking of ftp, but I didn't know if it was the safest way to go.

I have cygwin on this PC...how do i start the ssh server and specify the ports?

[Wombat]

ssh-host-config should get you started.

[Kooldino]

It guided me through, but there was nothing about ports.

[Kooldino]

Any easier ideas on opening another port? I'd rather not install an FTP program...and even if I did, it would have to listen on TWO ports.

And odds are they'd STILL know you're not running their program. Sorry, dude.

[Kooldino]

Someone on the other side told me they just looked for opened listening ports.

I think I have a solution...

...how about the rsh command built into xp (..type rsh /?)

You could just use telnet and specify a port number.

O:\>telnet 127.0.0.1 92
Connecting To 127.0.0.1...Could not open connection to the host, on port 92: Con
nect failed

Of course, you'd need to setup a telnet server to accept connections on that port. You could use any TCP program that allows you to use different ports as long at it connects, it will open that port.

nc -l -p #### works like a champ.

Now I just need to figure out how to hide these cmd.exe windows.

[Kooldino]

Got it...to start it without a window...

nc -L -d -p ####

Figured it out by reading
