How can I run a Python program over telnet?

How can I run a Python program so it outputs its STDOUT and inputs its STDIN to/from a remote telnet client?

All the program does is print out text then wait for raw_input(), repeatedly. I want a remote user to use it without needing shell access. It can be single threaded/single user.

You can just create a new linux user and set their shell to your script.

Then when they telnet in and enter the username/password, the program runs instead of bash or whatever the default shell is.

If you don't need full telnet functionality, you can just use a socket.

Check out the Socket Server module in the standard python library. It'll enable you to easily write a program that'll listen on a port for input/output.

It won't support the proper telnet protocol negotiation, but you might not need that for what you're doing.

Make the Python script into the shell for that user. (Or if that doesn't work, wrap it up in bash script or even a executable).

(You might have to put it in /etc/shells (or equiv.))

On a Unix system, you can use inetd for this. It will take care of opening the network connection for you, so your program will work as-is.
