How To Use Telnet To Establish a Virtual Terminal Connection to a Remote Node

How To Enable Telnet

You can enable Telnet in either of the following ways:

In the Quick Configuration screen, set the ‘‘Telnet enabled’’ parameter to ‘‘yes’’ and reboot the router.

In the Configuration Editor, set the Session Mode parameter to ‘‘Telnet’’ and reboot the router. (Session Mode is in the System/System Session menu.)

How To Use Telnet

Syntax

telnet X.X.X.X

where X.X.X.X is the IP address of the remote node in dotted decimal notation.

Example

telnet 15.3.0.97

Once a connection is established, Telnet passes keystrokes from your router to the remote node and displays the remote node’s control screen in the same way that it would be displayed if your console was directly connected to the remote node.

Telnet Access to Another HP Router

If the remote system is another HP router, you will see the Main menu of the remote router with the remote system name at the top of the screen. You can then operate the remote router in the same way that you operate the router to which you are directly connected.
