open-source network simulation tools that run on Linux or BSD systems
GNS3 can be used to simulate a network composed exclusively of open-source routers, switches, servers, and hosts. In this post, we will investigate how well GNS3 works when we use it strictly as an open-source network simulator, without using Cisco or Juniper routers in the simulation.
We tool a first look at the Common Open Research Emulator (CORE) in a previous post. We used the VCORE virtual appliance that we downloaded from the CORE web site to evaluate CORE but we found some issues with missing software. Now, we will install CORE on an Ubuntu Linux system as the first step
In this article, we will review the procedures required to install Debian Linux in a virtual machine managed by the VirtualBox application. A summary of the procedures is listed below: Download the Debian install DVD. Create a virtual machine using the VirtualBox application. Boot the virtual machine from the DVD image we downloaded Install the
