SSH Control of LXI Devices

Pickering LXI devices include a Secure Shell (SSH) service which will allow a user to remotely login to the LXI device and control its switching functions.

Enabling the SSH service

The SSH interface is normally disabled, here is the process for enabling it:

First from the LXI home page:

Select the 'Security' web page:

Then enter a password. This process enables security on the LXI device, restricting access to most device webpages unless the password is supplied. The username for this access to pages is 'admin', a second username 'sshuser' for SSH access is also created.

Next, navigate to the Diagnostics page (supply the username 'admin' and above password if requested), and enable the SSH service using the button at the bottom of the page.

The SSH service is now enabled.

Remote Access to the SSH service

A suitable SSH client must be used to access the LXI device, PuTTy is such a tool, http://www.putty.org/ provides links to some access tools, including PuTTy.

Enter the LXI IP address and then open the connection

You should obtain a login console, enter the username 'sshuser' and the password you entered during the security steps above.

The terminal should now display an interactive program for control of the switch cards:
