So people have written server programs using telnet in which the user simply does
telnet server.com and this connects them to the server program, which then provides them with a textual program they can use over the net (like a MUD). There are some here, for example:
I wanted to write a server program like that, but I want it to have security against evesdropping and MITM attacks that SSH offers. So is it possible to write a program in which the user can do this on a linux machine
ssh server.com or maybe this
ssh email@example.com and be patched into a similar text program as these telnet servers?
