Although GNS3 can run local on your computer and you can use VMware Workstation and have the GNS3 appliance. I found it much more stable and predictable to run GNS3 on a dedicated server. Using this type of installation, all the projects, and images are stored on the GNS3 server, so I can install the GNS3 client any computer and get access to the same projects I was working on. You can also have multiple people working on different projects that are on the same server. I find that neat for educational use or if you where helping someone with a project. In this post I’ll walk though the steps needed to set up a GNS3 server.
It’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.

Get your IOS, IOU, XRV, 1000v, HP, Juniper, Arista, and other images ready because that’s the beauty of GNS3, it’s here and ready to download. I’m excited for this release although the last post I did was In May of 2014, which was about getting GNS3 Alpha 3 working on Windows, you can see the full post here: GNS3 Alpha – Install and Setup. I have followed the GNS3 releases throughout the six months of them releasing Alpha and beta releases, as well as looking at changlogs of each release. So over the past six months we have seen some changes with the GNS3 team. The new logo, the new website, and of course the new 1.0 version of GNS3. They have also done a good job of setting up a new portal called the GNS3 Jungle which is for the community to ask all things networking all of which is available now. Check out all of it at http://www.gns3.com/.
Currently the GNS3 website is a little slow because I think we are all excited for the new software and can’t wait to get our hands on it but I was able to register so I’ll be posting more about the new version of GNS3 so keep that in mind, and check me out the GNS3 Jungle lewiryan. Thanks again Stephen and Jeremy and the entire GNS3 team for building a great piece of software with the help of an awesome community. Another interesting read that I found was a post from NetworkCanuck about an Interview with Steven from GNS3, read it here: GNS3 – An Interview. So I’ll end this post with what are you loading into GNS3?
So Alpha 3 came out last week with a bunch updates and I decided to give it run this week. I’m not doing anything that difficult with the program so maybe I’m not breaking it in all the way but I also was looking at some installation notes for Ubuntu and other Linux flavors, I figured I’ll try to install it on a Windows machine and not Linux (call me lazy) feel free to follow this guide.

It’s been almost 24 hours since GNS3 launched a campaign to bring in funds to support the open source network simulator and bring it up to version 1.0. A lot of new features are on the list, like switching, cloud processing, hassle free configuration, labs/training materials and 3rd party integrations. All of which are in the works for this new version added along with some pretty cool plug-ins. As of writing this post they are at $106,973 dollars which is 300 percent over funded! A pretty good turnout in fact they meet their goal in less than 4 hours of stating the campaign and have 16 days left to go. Continue reading “GNS3 1.0 Campaign”
