In a previous post, I showed how easy it is to set up a remote server on Amazon’s AWS service. Now I would like see if I can run one or more of the open-source network simulators I’ve been using on this remote server. I want be able to access a network simulator from any […]
I recently set up a free Amazon AWS server. As I experimented with it, I installed a GUI desktop. Then I encountered some issues that I eventually resolved by creating a new user with its own password and then using that user for the rest of my activities. For my own reference, and in the
As an incentive to use their service, Amazon Web Services offers new users a “free tier” of service that provides a VPS “micro-instance” at no cost for one year. The free tier of service is fairly flexible. Amazon AWS provides enough free hours to run the micro-instance twenty-four hours a day for a year but,
CORE Services is a feature of the CORE Network Emulator — an open-source network simulator — that configures and starts processes on each node running in a network simulation. Examples of processes supported by CORE Services are: quagga, dhcpd, or radvd. Because the CORE Network Emulator implements its virtual nodes using a lightweight virtualization technology
To run virtual nodes in a simulated network, the GNS3 open-source network simulator supports two virtualization technologies: Qemu and VirtualBox. The open-source routers we will use in a GNS3 simulated network must run on either a Qemu or a VirtualBox hypervisor. Depending on one’s requirements, one might choose either VirtualBox or Qemu. Let me tell
I’ve been using Parallels Desktop for Mac to run a Debian Linux 6.0 virtual machine. I wanted to install the Parallels Tools in the Debian virtual machine so I could take advantage of better integration between the Linux virtual machine and the Mac OS X host computer. It wasn’t as straightforward as I thought it
A network of virtual machines can be used for practical testing and research. Sandia National Laboratories recently announced that they have created a virtual network of three hundred thousand virtual machines, each of which is running the Android operating system, on a single large supercomputer. In the recent past the researchers at Sandia National Laboratories
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
I am building a virtual machine that will run the open-source network simulation tools that I want to research. There are good reasons to use a virtual machine for these experiments, even if software running inside a virtual machine may run slightly slower than software running on a native host. Below, I list the benefits
