SSH Command Summary

SSH

Secure Shell (SSH) version 2 enables secure network terminal sessions between a Switched PDU Remote Power Manager and a remote user over insecure network. SSH provides an encrypted terminal sessions with strong authentication of both the server and client, using public-key cryptography and is typically used as a replacement for unencrypted Telnet. In addition to enabling secure network terminal sessions to the Switched PDU for configuration and power management, the SSH session may be used for secure pass through connections to attached devices.

SSH requires the configuration and use of a client agent on the client PC. There are many freeware, shareware or for-purchase SSH clients available. Two examples are the freeware client PuTTY and the for-purchase client SecureCRT ® by VanDyke® Software. For configuration and use of these clients, please refer to the applicable software documentation.

SSH Command Summary

Command

Description

Set SSH

Enables/disables SSH support

 

 

Set SSH port

Sets the SSH server port number

Enabling and Setting up SSH Support

NOTE: A restart of the Switched PDU is required after setting or changing ANY SSH configurations. See Performing a warm boot on page 39 for more information.

Enabling or disabling SSH support

The Set SSH command is used to enable or disable SSH support.

To enable or disable SSH support:

At the Switched PDU: prompt, type set ssh, followed by enabled or disabled and press Enter.

Changing the SSH server port

With SSH support enabled, the SSH server watches and responds to requests on the default SSH port number

22.This port number may be changed using the Set SSH Port command.

To change the SSH port:

At the Switched PDU: prompt, type set ssh port, followed by the port number and press Enter.

Example

The following changes the SSH port number to 65535:

Switched PDU: set ssh port 65535<Enter>
