How to later integrate Solar-Putty with GNS3 as the preferred console application

Starting the GNS3 version 2.1.10, Solar-Putty is packaged as the default SSH client. However, how to integrate it to GNS3 later? As it was not selected during the GNS3 installation? Follow:

1. Download the Solar Putty application from https://www.solarwinds.com/free-tools/solar-putty. Puty is zipped, therefore after the download has completed, unzip the Solar-PuTTY.exe application file to your preferred application folder. I used the C:\Program Files (x86)\Solar-Putty\ for that.

How to easily add Open vSwitch to GNS3

Open vSwitch (OVS) is a multilayer (MLS) virtual switch licensed under the open-source Apache 2.0 license which is widely used in the field of virtual networking. With this open-source MLS switch, we can easily extend GNS3 switching capabilities. We can add this switch to GNS3 very quickly using a GNS3 OVS appliance. No base Linux system VM is required, no ISO images.

In this post I’m going to describe how to add and run OVS MLS inside of the GNS3 (local or remote).
