Is it possible to open a "shell" on another computer via RedNet?

Is it possible to use one computer and interact with another computer's shell remotely over Rednet? So you use a specific computer normally but from another location?

Yes that is possible but it will require a connection via Wireless modems or a bundled redstone cable. And a programm running on both pcs

On the client (the PC to be controlled) you'll need something that keeps in a loop and pulls rednet events it would have to analyse the text and then call the according function with the correct parameters. If you also want to send back the console output you'll have to maybe rewrite the term functions to redirect everything over rednet.

Wouldn't the computer receiving the commands be the server? The user is using the box sending commands, and the server is processing them, so it would make more sense that way.

Soon. My OS is still under construction though.

Well maybe you're right but actually it doesn't matter how you call them

Indeed, but this is the standard terminology used in telnet and SSH and remote desktop and such, to it helps people understand what your are talking about if you name it the same way, where the server receives and runs commands, and the client sends commands and receives results.

My problem is my attentions are currently split in four directions. One of my projects is this one: creating a "window" system that lets you have multiple terminals per screen, terminals mirrored across screens, swap between different terminal tabs, display terminals running on remote computers, etc. But I also am working on multiprocessing system, trying to figure out how to set up multiple users, and help with OCL. And I still don't have a good, secure networking system (but my place-holder system will do in a pinch.)

You could use loadstring()

Sender:

Spoiler

rednet.open("right")– change to the appropriate side
command = "print("Hello, World!")"
rednet.broadcast(command)

Receiver:

Spoiler

rednet.open("right")
id, msg = rednet.receive()
a = loadstring(msg)
a()

The key goal of remote administration tools is to be silent, if you're silent they will never suspect a thing. This is good for stealing software from rival companies in the game.

No, the key goal of remote administration tools is to allow legitimate users of a computer to control it without direct access. They shouldn't be used for malicious purposes. More on topic, a client-server system with a term redirect is good way to go. I'd also recommend an authentication system on the server if you're playing SMP.
