On the left side of image, we have created simple topology and we can observe in lower right section that immediately all 4 vCPU cores started working. To test real benefits lets add some switches and turn them on. EvaluationĪt the moment, we just started our GNS3 server, therefore no excessive CPU usage takes place on our instance. Select “Run this IOS router on a remote computer” and configure node to your liking. Next, go to Dynamips > IOS routers and create new Router. ip-172-31-36-149) and for Host insert instance’s public IP while Port stays at 3080 TCP. For Name insert instance’s private IP (e.g. On the local machine open GNS3 GUI and click Preferences > Server > Remote servers > Add. To be positive, open your browser and type in your instance’s IP and default port number 3080. $ sudo cp src/dictionary.h /usr/local/includeīy now, we should be running GNS3-server as the image above shows. $ sudo cp src/iniparser.h /usr/local/include $ sudo setcap cap_net_admin,cap_net_raw =ep /usr/local/bin/dynamips $ sudo apt‐get install python3‐setuptools Click save and lets connect to our newly created machine. To do this click on “Edit inbound rules” and change “Type” to “All traffic”. By creating an instance, we also have a “Security Group” which we have to modify to allow inbound traffic. Our instance should be up and running by now. Note: Check out this link for more info: EC2 PricingĪfter clicking Launch next step is to “Create a new key pair” and save it for later use. Again, the best thing is to do a research of your own and select what suits your ops the most. Now, the deal with AWS EC2 usage and pricing predictions can vary from various factors. You are free to select an instance-type based on your requirements and budget but in my case I chose to use m3.xlarge instance with following configuration. On the next step we can decide what type of hardware to run. Since I’m in Europe, my instance is in Frankfurt. Thus, be aware to choose your nearest Amazon location in top-right corner, next to your name. Important: Different types of instances are offered in different locations. Here choose the first option that aws provides us with ubuntu-xenial-16.04-amd64-server. Inside EC2 management console, select Launch Instance and choose Community AMIs. ![]() ![]() To do this go to aws services and select EC2. Let’s create a Linux running instance on top with Ubuntu Server Xenial (16.04). ![]() It is important to note that the client app and GNS3-server need to be same version, so if you did not already update your client, take a moment and do it now. The idea of using someone elses hardware to do processor heavy-lifting seemed like a perfect pivot direction.Īs a remote hosting server we will be using Amazon AWS EC2 instance. To cope with this problem, just recently decided to run GNS3 server as a remote server with the front GUI app residing in my local machine. ![]() Ever since I purchased my Macbook Pro, wasn’t able to simulate GNS3 topologies without my machine overheating and causing me distress. ![]()
