Hati, lets see, you have machine 1 and machine 2
let us say you are sitting on machine 1
you are trying to telnet into machine 2 to port 4965
First sit on machine 2 and do telnet localhost 4965
Are you able to?
If yes, then telnet <machine 2 IP> 4965
If succesful try telnet from machine 1 using telnet <machine 2 IP> 4965
It is on the machine 2 you should be opening up the port 4965
