Secure Shell Commands
The Berkley-standard includes remote access tools originally designed for Unix
systems. Some of these tools have also been implemented for Microsoft Windows
and other environments. These tools, including commands such as rlogin (remote
login), rsh (remote shell), and rcp (remote copy), are not secure from hostile attacks.
The Secure Shell (SSH) includes server/client applications intended as a secure
replacement for the older Berkley remote access tools. SSH can also provide
remote management access to this switch as a secure replacement for Telnet.
When a client contacts the switch via the SSH protocol, the switch uses a public-key
that the client must match along with a local user name and password for access
authentication. SSH also encrypts all data transfers passing between the switch and
SSH-enabled management station clients, and ensures that data traveling over the
network arrives unaltered.
This section describes the commands used to configure the SSH server. However,
note that you also need to install a SSH client on the management station when
using this protocol to configure the switch.
Note:
The switch supports both SSH Version 1.5 and 2.0.
