Setting up GNS3 1.1 on Ubuntu

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

Cisco Lab Setup

When it comes to learning and getting started with Cisco there are some tools that will help out a lot like Packet Tracer, GNS3 and other emulators. These are great tools for that “simulation” of hands on learning, but you can’t always stay in that area. I find it best to get hands on with “real” Cisco Gear and so with this post I’ll go through my current setup of what I have and ask that question when it is a good time to get a lab? Just because you may want to get a lab that does not guarantee you’ll actually learn and or pass.   Continue reading

Password Recovery – Cisco IOS Routers

 

In this post I want to cover how to recover passwords on a Cisco IOS Router. This is helpful in lab environments as well as production environments. Although this method can be used the correct “legal” way you can also use this method to break into these devices “illegally” if you have physical console access to the device. However to get into it physical power must be turned off first causing a disruption in the environment, let get started! Continue reading
