Setting up GNS3 1.1 on Ubuntu

Posted on by Ryan

gns3_logoIt’s only been a week since GNS3 1.0 was released and it’s already been updated to 1.1 so in this post I have Ubuntu 14.04 LTS with the latest updates and its time to set up GNS3. GNS3 is an open source tool that helps network professionals run a virtual network right on their computer, GNS3 is not a simulation program but rather an emulation program. So if you wanted to test a configuration change but did not want to run it on production you can run it in GNS3 instead.  This gives network professionals testing without touching any physical hardware or purchasing that expensive test lab for certification studies. Let’s get started. Continue reading “Setting up GNS3 1.1 on Ubuntu” →

Part 1 – The Joys of Subnetting!

Posted on by Ryan

Since network technicians work with IP addressing, it is hugely important to understand subnetting. I remember back when I started to learn subnetting it was confusing and I wanted nothing to do with it. The thing that made me change my mind was after I understood it and how important it is. In the “Cisco world” they don’t cover useless topics, there is always a reason why they expect you to know this and it’s not just for the exams. Subnetting has always had its moments with people and in this blog I’ll do my best to show you what I have done to make subnetting an easier experience.
