Chapter 3 Configuring SSH Terminal Service
Secure Shell (SSH) is a feature that provides information about security and powerful
authentication functions, which can protect a router from the attacks such as IP
address spoofing and plain text password. This is especially evident for remote users
who access the router from a nonsecure network environment. The router provides
simultaneous access of multiple SSH clients. SSH client allows a user to set up the
SSH connection with an SSH-supported router or UNIX host. As shown in Figures 2-1
and 2-2, you can set up an SSH channel for the purpose of local or WAN connection.
V1.20 supports SSH Server 1.5.
