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 Cloonix open-source network simulator uses the Spice remote desktop system to provide a virtual desktop connection to quest virtual machines that run a graphical user interface, such as Microsoft Windows or a Linux desktop environment. To use a graphical desktop user interface on a guest VM, we access the VM using the Spice desktop
To run a program that uses a graphical user interface on a guest virtual machine running in the cloonix open-source network simulator, log into the guest VM from the host computer using SSH and forward the X11 display. Then, any X11 program you run on the guest VM using that SSH session, such as Wireshark,
As we work through this tutorial, we will learn how to use the cloonix graph interface to build a simulation scenario that includes two small IPv6 networks connected to each other by two routers via static routes. We will also learn how cloonix saves network topologies and guest virtual machine root filesystems. The cloonix open-source
The cloonix project provides a variety of root filesystems for use in the cloonix network simulator. These root filesystem only have the most basic software packages installed and will not support advanced network configuration (with the exception of router filesystems such as openwrt). To create a network simulation that runs real-world networking software, we need
The cloonix development team recently updated the cloonix network simulator to version 24. This post describes the changes in cloonix v24 compared to cloonix v19, which we reviewed in a previous post. Version 24 simplifies the setup of guest virtual machines, improves the link performance emulation tool, and adds new interface types designed to improve
The Cloonix open-source network simulator was recently updated to version 24. The last time I used Cloonix, it was at version 19 (see my review of Cloonix and my using the Cloonix graph interface posts). Compared to version 19, only a few details of the installation procedure have changed — the list of package dependencies
The Cloonix development team recently released Cloonix version 21. The new version includes some significant improvements, such as support for Cisco software images (via Dynamips) and support for 32-bit architectures. The Cloonix developers also added a large library of prepared filesystems including new, lightweight versions of popular linux filesystems, such as debian, ubuntu and fedora,
We will install the Cloonix open-source network simulator on a Knoppix Live USB drive. Knoppix is a version of Linux that is designed to boot from a CD, DVD, or USB drive. It can run on almost any computer hardware and it runs in memory, so it does not affect the hard drive of computer
