Looking for single file telnet server to hack into application

Question

Hi, I've been looking for some very simple to lift and simple telnet source code to build into an application I am working on. I have looked at some traditional Linux applications of this and they are build and they are overkill, comprised of about 20 files, and have way too many dependencies. I just want simple, and (NO) I do not care at all about security, actually security in this case would be a liability. Just simple telnet server code.

I had actually though this would be pretty simple to locate, but so far no luck at all. If you can think of an app or something that has a telnet server built in using only one (maybe two files) or even a really simple telnet server, please let me know.

Thanks!

If you simply want to accept telnet connections, but don't need to spawn a shell or anything, you could just use plain sockets. And, well, if you need to spawn a shell, that should only be a couple more lines of code. I'm assuming you're using C.

If you just need a simple telnet server that spawns a shell, socat may be worth trying.
