Hi everybody,
I create a program to connect and to send command  to various systems.
I have a lot of protocol like SSH,TELNET and RLOGIN.

I suceed the connection in SSH.

I try to make the same work in Telnet by changing the port 22 into port 23.
But my program is not operate.

I want to ask you if I can the connection in Telnet first and after in Rlogin?
