I would like to be able to print to the terminal of a computer on a different network (this should work bilaterally). I understand that this should be possible by using the command
ntalk, but I have not been able to figure out how.
As I understand it, a way to do that would be to set up a restricted shell for a ssh user which would allow that user to print in the terminal, while not being able execute any other commands, so solutions for that would also be appreciated (as well as any other for that matter).
I'm just looking for a low security risk way to establish a point to point chat similar to IRC and with a minimal requirement to instal or configure additional software if OS X ships with something that can work.
ntalk work between another computer and Mac OS X?
