Using Telnet or SSH to access a serial target

An authorized user can use a Telnet or SSH client to make a connection directly to the console of a

serial target if all of the following are true.

The Telnet or SSH:

• protocol is enabled for network service in the security profile

• protocol is configured for the port

• client is available, and it is enabled on the computer from which the connection is made

To use Telnet to connect to a target through a serial port:

For this procedure, you need the username configured to access the serial port, the target name

(for example, 14-35-60-p-1), device name (for example, ttyS1), TCP port alias (for example, 7001)

and the hostname of the appliance or its IP address.

To use a Telnet client, enter the information in the dialog boxes of the client.

-or-

To use Telnet in a shell, enter the following command:

# telnet [hostname | IP_address]

-or-

# telnet [hostname | IP_address] TCP_Port_Alias

To close a Telnet session:

Enter the Telnet hotkey defined for the client. The default is Ctrl + q to quit.
