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

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.
