4.2.2 SSH

4.2.2.1 Introduction to SSH

SSH (Secure Shell) is a protocol which ensures a secure remote access connection to net work devices. It is
based on the reliable TCP/ IP prot ocol. By conducting the mechanism such as key distribution, authentication
and encryption between SSH server and SSH client, a secure connection is established. The information
transferred on this connection is protected from being intercepted and decrypt ed. The Chassis Switch meets
the requirements of SSH2. 0. It supports SSH2.0 client software s uch as SSH S ecure Client and putty. Users
can run the above software to manage the Chassis Switch remotely.
The Chassis Switch presently supports RSA authentication, 3DES cryptography prot ocol and SS H user
password aut hentication etc.

Admin Mode
| host Login to a remote host with the Telnet client
included in the Chassis Switch.
Enable SSH function on the Chassis Switch; the
"no ssh-server enable" command disables SSH
function.
Configure the username and password of SSH
client software for logging on the Chassis Switch;
the "no ssh-user <user-name>" command
deletes the username.
Configure timeout value for SSH authentication;
the "no ssh-server timeout" command restores
the default timeout value for SSH authentication.
Configure the number of times for retrying SSH
authentication; the "no ssh-server
authentication-retries" command restores the
default number of times for retrying SSH
authentication.
Generat e the new RSA host key on the SSH
server.
