open-source network simulation tools that run on Linux or BSD systems
No Starch Press recently sent me a preview copy of a new book about the GNS3 network simulator, titled The Book of GNS3 written by Jason Neumann. This book covers the new version of GNS3, GNS3 1.x. Here is my review of The Book of GNS3. The Book of GNS3 effectively serves as a user […]
The GNS3 development team produced a major new release, version 1.0, in October 2014. Since then, they have been regularly updating GNS3 and, at the time I write this, the latest version of GNS3 is version 1.3.7. The latest version of GNS3 cannot be installed using a package manager like Ubuntu Software Center or Synaptic
Open-source DevOps tools are used to deploy applications and services in datacenter server networks, but they may also enable researchers or students to simulate networks. In this post, we will survey popular open-source DevOps tools and provide links to information that shows how to use them to create network simulation scenarios. Most open-source network simulators
The CORE Network Emulator has been updated to version 4.8. This new version fixes the issues I noted in my previous review of CORE release 4.7. It also implements some new features. See the CORE 4.8 release notes for all the details. The most visible change is the addition of some new services — most
The Cloonix development team released an update to Cloonix version 26 in May 2015. An important addition in version 26 is a greatly expanded and improved Cloonix user guide. The new version also changes the user interface, adds a new LAN type, and eliminates the t2t device. It also includes updated guest virtual machines.
The Mininet network simulator includes MiniEdit, a simple GUI editor for Mininet. MiniEdit is an experimental tool created to demonstrate how Mininet can be extended. To show how to use MiniEdit to create and run network simulations, we will work through a tutorial that demonstrates how to use MiniEdit to build a network, configure network
To install the Mininet SDN network simulator on a remote server running on Amazon’s EC2 cloud, follow the procedure shown below. After installing it, I did some basic tests and it seems that Mininet works well on the Amazon EC2 server.
I recently configured an Amazon EC2 instance so that I could run the XFCE desktop environment on it and control it from my local laptop computer using SSH and VNC. But what if I want to use my iPad to do control the remote Amazon EC2 server? I want to experiment with complex network simulations
Having set up an Ubuntu Linux server running on a free micro-instance in Amazon’s Web Services EC2 service, I’d like to see how some of the open-source network simulation tools I’ve been using work in the cloud. First, I will install the CORE Network Emulator on my Amazon AWS EC2 virtual private server. Please read
