With the telnet program one can connect to any TCP port on any host, but is there a way to listen on some port on current host?
1) on host a: telnet listen 12345
2) on host b: telnet host_a 12345
I don't want any service behind the listening side, just connection and whatever typed to be transferred as is both ways.
I know I can already do the 2), but is there any way to achieve the 1)? I'm interested in both Windows and Linux solution.
