FTOS Configuration Guide for the C-Series - Force10 Networks

SCP and SSH
Secure Shell (SSH) is a protocol for secure remote login and other secure network services over an
insecure network. FTOS is compatible with SSH versions 1.5 and 2, both the client and server modes. SSH
sessions are encrypted and use authentication. For details on command syntax, see the Security chapter in
the FTOS Command Line Interface Reference.
SCP is a remote file copy program that works with SSH and is supported by FTOS.
To use the SSH client, use the following command in the EXEC privilege mode:
Command Syntax Command Mode Purpose
ssh {hostname} [-l username |
-p port-number | -v {1 | 2}
EXEC privilege Open an SSH connection specifying the hostname,
username, port number, and version of the SSH
client.
hostname is the IP address or hostname of the
remote device.
