Enabling Scp And Ssh; Using Scp With Ssh To Copy A Software Image - Dell Force10 Z9000 Configuration Manual

Enabling SCP and SSH

Secure shell (SSH) is a protocol for secure remote login and other secure network services over an insecure network. Dell
Networking OS is compatible with SSH versions 1.5 and 2, in both the client and server modes. SSH sessions are encrypted and use
authentication. SSH is enabled by default.
For details about the command syntax, refer to the Security chapter in the Dell Networking OS Command Line Interface Reference
Guide.
Dell Networking OS SCP, which is a remote file copy program that works with SSH.
NOTE: The Windows-based WinSCP client software is not supported for secure copying between a PC and a Dell
Networking OS-based system. Unix-based SCP client software is supported.
To use the SSH client, use the following command.
• Open an SSH connection and specify the hostname, username, port number,encryption cipher,HMAC algorithm and version of
the SSH client.
EXEC Privilege mode
ssh {hostname} [-l username | -p port-number | -v {1 | 2}| -c encryption cipher | -m HMAC
algorithm
hostname is the IP address or host name of the remote device. Enter an IPv4 or IPv6 address in dotted decimal format
(A.B.C.D).
• SSH V2 is enabled by default on all the modes.
• Display SSH connection information.
EXEC Privilege mode
show ip ssh
Specifying an SSH Version
The following example uses the ip ssh server version 2 command to enable SSH version 2 and the show ip ssh
command to confirm the setting.
Dell(conf)#ip ssh server version 2
Dell(conf)#do show ip ssh

SSH server version
SSH server vrf

To disable SSH server functions, use the no ip ssh server enable command.

Using SCP with SSH to Copy a Software Image

To use secure copy (SCP) to copy a software image through an SSH connection from one switch to another, use the following
commands.
On the chassis, invoke SCP.
