Port Configuration Access Errors

A connect: Connection refused message while trying to access a particular Terminal Concentrator port using telnet(1) can have two possible causes:

• The port is being used by someone else.

• The port is misconfigured and not accepting network connections.

How to Correct a Port Configuration Access Error

1. Telnet to the Terminal Concentrator without specifying the port, and then interactively specify the port.

   # telnet terminal-concentrator-name Trying ip_address .. Connected to 192.9.200.1 Escape character is '^]'. [you may have to enter a RETURN to see the following prompts] Rotaries Defined: cli - Enter Annex port name or number: 2

   If you see the following message, the port is in use.

   Port(s) busy, do you wish to wait? (y/n) [y]:

   If you see the following message, the port is misconfigured.

   Port 2 Error: Permission denied.

   If the port is in use, reset the Terminal Concentrator connections using the instructions in "Resetting a Terminal Concentrator Connection".

   If the port is misconfigured, do the following:

   1. Select the command-line interpreter (cli) and become the Terminal Concentrator superuser.

      Enter Annex port name or number: cli Annex Command Line Interpreter * Copyright 1991 Xylogics, Inc. annex: su Password:

   2. As the Terminal Concentrator superuser, reset the port mode.

      annex# admin Annex administration MICRO-XL-UX R7.0.1, 8 ports admin: port 2 admin: set port mode slave You may need to reset the appropriate port, Annex subsystem or reboot the Annex for changes to take effect. admin: reset 2 admin:

The port is now configured correctly.
