Chapter 1 SSH Terminal Services

1.1 SSH Terminal Services

1.1.1 Introduction to SSH

Secure Shell (SSH) can provide information security and powerful authentication to

prevent such assaults as IP address spoofing, plain-text password interception when

users log on to the Switch remotely via an insecure network environment.

A Switch can connect to multiple SSH clients. SSH2.0 is currently available. SSH client

functions to enable SSH connections between users and the Switch or UNIX host that

support SSH server.

Figure 1-1 and Figure 1-2 shows respectively SSH connection establishment for client

and server.
