Configuring for Secure Shell (SSH) Access

The SR2122-2 Storage Router supports Secure Shell (SSH) as an alternative to
Telnet protocol for SR2122-2 management. SSH provides encryption and strong
authentication for interactive SR2122-2 management sessions. The SR2122-2
supports SSH protocol version 2 and allows port forwarding.
The SR2122-2 SSH implementation supports execution of interactive commands
only; non-interactive commands cannot be executed. Secure FTP (sftp) and
Secure Copy (scp) are not supported.
SSH is enabled for the SR2122-2 and the SSH service is started, by default.
However, you must generate a public/private key pair for the SR2122-2 before you
can use SSH to establish a management session. By default, SSH is restricted on
all interfaces except the management interface.
