8.4 Logging in to Another Device by Using STelnet

STelnet ensures secure Telnet services. You can log in to another router from the router that you
have logged in to by using STelnet, and thus to manage the device remotely.

8.4.1 Establishing the Configuration Task

Before establishing the configuration task of logging in to another device by using Stelnet,
familiarize yourself with the applicable environment, complete the pre-configuration tasks, and
obtain the required data. This can help you complete the configuration task quickly and
accurately.
Applicable Environment
Logins by using Telnet bring security risks because no secure authentication mechanism is
available and data is transmitted by using TCP in plain text mode.
STelnet is short for SSH Telnet that is a secure Telnet protocol. STelnet is on the basis of SSH.
SSH users can use STelnet services as Telnet services.
In this configuration, the Router that you have logged in to functions as a Telnet client, and
theRouter that you attempt to log in to functions as an SSH server.
Pre-configuration Tasks
Before logging in to another device by using STelnet, complete the following tasks:

Data Preparation
To log in to another device by using STelnet, you need the following data:

8.4.2 Configuring the First Successful Login to Another Device
(Enabling the First-Time Authentication on the SSH Client)
After the first-time authentication on the SSH client is enabled, the STelnet client does not check
the validity of the RSA public key when logging in to the SSH server for the first time.
