This section describes the procedures about how to use the terminal concentrator in a cluster.
Table 2-1 Task Map: Using the Terminal Concentrator
# telnet tc-name tc-port-number
Specifies the name of the terminal concentrator.
Specifies the port number on the terminal concentrator. Port numbers are configuration dependent. Typically, ports 2 and 3 (5002 and 5003) are used for the first cluster that is installed at a site.
Note - If you set up node security, you are prompted for the port password.
After establishing the telnet connection, the system prompts you for the login name and password.
# TERM=xterm # export TERM
Example 2-3 Connecting to a Node's Console Through the Terminal Concentrator
The following example shows how to connect to a cluster node in a configuration that uses a terminal concentrator. A Shell tool has already been started by using an xterm window.
admin-ws# telnet tc1 5002 Trying 18.104.22.168 ... Connected to 22.214.171.124. Escape character is '^]'. [Return] pys-palindrome-1 console login: root password: root-password (for sh or ksh) phys-palindrome-1# TERM=xterm; export TERM (for csh) phys-palindrome-1# set term=xterm
When a port on the terminal concentrator is busy, you can reset the port to disconnect its user. This procedure is useful if you need to perform an administrative task on the busy port.
A busy port returns the following message when you try to connect to the terminal concentrator.
telnet: Unable to connect to remote host: Connection refused
If you use the port selector, you might see a port busy message. See How to Correct a Port Configuration Access Error for details on the port busy message.
# telnet tc-name
Specifies the name of the terminal concentrator
Enter Annex port name or number: cli annex:
The default password is the terminal concentrator's IP address.
annex: su Password:
The who command shows ports that are in use.
annex# admin reset port-number
You can now connect to the port.
Example 2-4 Resetting a Terminal Concentrator Connection
The following example shows how to reset the terminal concentrator connection on port 2.
admin-ws# telnet tc1 Trying 126.96.36.199 ... Connected to 188.8.131.52. Escape character is '^]'. [Return] ...
