How To Use Telnet To Establish a
Virtual Terminal Connection to a
Remote Node
Telnet uses the Transmission Control Protocol (TCP) to enable you to
use the terminal connection to your local router as a virtual terminal
connection to a remote node, such as another router. This generally
gives you the ability to access and control the remote node in the same
way that you would if your terminal was directly connected to that node.
If the remote node is another HP router, you can use Telnet access to
operate the remote router’s statistics, NCL, configuration, and event log
in the same way that you can operate these same features in a local
(direct terminal connection) HP router. You can have up to two
simultaneous TCP connections; one inbound and one outbound.
Prerequisites for Telnet Operation
Telnet requires the following:
The remote node must have Telnet service operating
The following must be configured in your local router:
• System parameters
• Software Protocol parameter configured to ‘‘DoD IP Router’’
• The appropriate Lines parameters
• The appropriate Circuit and Circuit Group parameters
• IP (the DoD Internet Router)
• A Telnet session
Note Use of Telnet for outbound access from a local router to other devices is
automatically enabled if DoD Internet Router (IP) is configured. How-
ever, for inbound access to a router from other devices, Telnet must be
specifically enabled on that router.
