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.
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 SSH version 1.5 and 2.0.
