Security: SSH Server
This section describes how to establish an SSH session on the device.
It covers the following topics:
• Overview
• Common Tasks
• SSH Server Configuration Pages
Overview
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.
