Windows 7: Telnet Port

Telnet Port


I am using Win 7 Prox64. I enabled telnet client and server. I am able to connect on the default port 23.

In windows firewall I added port 4001 but I am unable to telnet to this port. I am unable to connect even if I disable the firewall.

If I use the cmd - tlntadmn config port=4001 I get an error - Invalid Value. Specify a positive number less than 1024 for Port Option.

If I set it to 1001 I am able to telnet to that port.

Please let me know how I can set it to 4001.

Thank you.

You can't. See here: Tlntadmn

It says:config port = <Number> Sets the Telnet port. You must specify the port with an integer smaller than 1024.
