How to Correct a Port Configuration Access Error

A misconfigured port that does not accept network connections might return a Connect: Connection refused message when you use telnet(1). Use the following procedure to correct the port configuration.

1. Connect to the terminal concentrator without specifying a port.

   # telnet tc_name

   tc_name 

   Specifies the hostname of the terminal concentrator

2. Press Return again after you make the connection, then specify the port number.

   Trying ip_address .. Connected to 192.9.200.1 Escape character is "^]". ... [RETURN] Rotaries Defined: cli - Enter Annex port name or number: 2

   • If you see a Port(s) busy, do you wish to wait? (y/n) message, answer N and go to How to Reset a Terminal Concentrator Port.

   • If you see an Error: Permission denied message, the port mode is configured incorrectly to the command-line interface and must be set to slave. Go to Step 3.

3. Select the terminal concentrator's command-line interface.
