Chapter 3: Installing the Ridgeline 3.1 Server
Ridgeline Installation and Upgrade Guide

Installing a Difference Viewer
Ridgeline provides a Diff feature that allows you to compare configuration files using a Difference
Viewer. This feature requires that a Difference Viewer be installed on the client system. A Difference
Viewer can automatically compare and highlight the differences between two files. The Diff feature does
not work with a standard text editor.
You can use any Diff viewer that is installed on the system where your Ridgeline client is running.
Select
Difference Viewer
from the
Tools
menu to tell Ridgeline the location of the viewer. If you do not
have a Diff viewer already installed, you must install one on your client system in order to use the Diff
feature.
For Windows.
You can obtain a Diff viewer from the following sources:
●
WinMerge.exe
; downloadable from
http://winmerge.sourceforge.net
●
Araxis Merge
; 30 day free trial evaluation downloadable from
http://www.araxis.com
For Linux or Solaris.
sdiff
(in
/usr/bin/sdiff
) is assumed as the default Diff viewer.
Enabling SSH for Secure Communications
By default, the Ridgeline server communicates to the devices it manages using unencrypted access, and
unencrypted file transfers. In addition, the communications between the Ridgeline server and its clients
are also unencrypted by default.
●
By installing an SSH enabling key, you can use SSH2 instead of Telnet to communicate to the devices
Ridgeline manages, and securely upload and download configuration files to and from your Extreme
devices.
●
By installing an SSH2 server co-resident with the Ridgeline server, and by installing SSH2 clients on
the systems where your Ridgeline clients reside, you can use SSH2 to encrypt the communications
between the Ridgeline server and Ridgeline clients. See the Appendix in the
Ridgeline Service Advisor
Concepts and Solutions Guide
for details on setting up secure client-server communication.
There are three requirements for enabling Ridgeline to use SSH2 to communicate with the devices it
manages:
●
The Ridgeline SSH enabling key must be installed. Due to export restrictions, you must obtain this
module from Extreme Networks. It is not included with the Ridgeline software distribution.
●
Your switches must be running versions of ExtremeWare or ExtremeXOS that support SSH, and SSH
must be enabled on those devices. Due to export restrictions, a special license is required.
To request versions of ExtremeWare or ExtremeXOS that support SSH, contact Extreme Networks
Technical Support.
●
SSH must be enabled in Ridgeline for the devices to which you want to communicate using SSH.
NOTE
If the SSH enabling key is not installed in the Ridgeline directory, you will not be able to configure SSH
in Ridgeline. The relevant fields will be grayed out.
