Help with remote shellll

How would one go about creating a shell for a computer to be accessed over the interbutt?

Direct sockets do not work for me. I wrote a shell that listens on a port, but I can't really access it by using my IP directly. (IE: connecting to x.x.x.x:999)

I know the issue relates to portforwarding, but I don't want to go down that route for now. Anyone have any ideas ?

I was thinking of having the shell connect to an IRC server, and take commands by PMs, but I want to know if there are other ways.

 

It would be much easier to simply port forward. This takes about 30 seconds to do from your computer. There aren't many other ways.
You can always use a central server as well. Like have a middle man that passes data from your computer to theirs.

 

Yeah, I was thinking of making a simple server in PHP, and have the clients connect to that.

Port forwarding is not always an available option, so I'm trying to avoid that.

 

What do you mean it isn't an option? It is just a simple opening the router/modem control panel and enabling the selected ports.

 

Combination of different Operating Systems, User Privledges & Modem Models will make it very difficult.

 

I think JDS means for the user to do it, not an automated process, but that would defeat the stealth part...

Another alternative is an automatic VPN creator / joiner.
