This section describes how to establish an SSH session on the device.

It covers the following topics:

Common Tasks

SSH Server Configuration Pages

The SSH Server feature enables users to create an SSH session to the device.

This is similar to establishing a telnet session, except that the session is secured.

Public and private keys are automatically generated on the device. These can be

modified by the user.

The SSH session is opened using a special SSH client application, such as PuTTY.

SSH Server can operate in the following modes:

By Internally-generated RSA/DSA Keys (Default Setting)—An RSA and a

DSA key are generated. Users log on the SSH Server application and are

automatically authenticated to open a session on the device when they

supply the IP address of the device.

Public Key Mode—Users are defined on the device. Their RSA/DSA keys

are generated in an external SSH server application, such as PuTTY. The

public keys are entered in the device. The users can then open an SSH

session on the device through the external SSH server application.
