![]() ![]() The GNS3 web site provides a set of prepared Linux appliances that can be used to emulate routers, servers, and hosts in a virtual network. At this point, we still cannot use GNS3 because we need to create the virtual machines that GNS3 will use in the emulated network. Now, we see the blank GNS3 application window. We do not need any of these setting when working exclusively with Linux virtual machines in GNS3. Just click on the “OK” button at the bottom of the wizard window. To start using GNS3, click on the menu command: Start → Education → GNS3 In the Xubuntu start menu, GNS3 appears under “Education” and Wireshark appears under “Internet”. To install the dkms package, execute the command: $ sudo apt-get install dkmsĪfter installation is completed, the Oracle VirtualBox virtual machine manager will appear in the Xfce menu under “System”. The Oracle web site also recommends installing the dkms package to ensure that VirtualBox is properly updated if the Linux kernel version changes during the a system upgrade. At the time of writing this post, the latest VirtualBox package was: virtualbox-4.3_4.3.6-91406~Ubuntu~raring_b. In my case, I chose to install the latest version of VirtualBox, version 4.3, using the procedure described above. ![]() The Ubuntu Software Center will automatically start and install the latest version VirtualBox from the downloaded. Then, in your File Manager, double-click on the. To install the latest version of VirtualBox, download the latest package from the Oracle VirtualBox web site. However, if you - like me - always want the latest and greatest version on your computer, follow the steps described below to install the most recent available version of VirtualBox. The version available from the Ubuntu repositories is good enough. ![]() The version of VirtualBox available in the Ubuntu Software Center is not the latest version available from VirtualBox’s developer, Oracle. Search for VirtualBox in the Ubuntu Software Center and click on “install”. The easiest way to install VirtualBox in an Ubuntu Linux-based system (I am using Xubuntu) is to use the Ubuntu Software Center program. When emulating nodes other than Cisco routers, GNS3 can use VirtualBox to manage the virtual machines that run linux (or other PC operating systems). The procedures I demonstrate using GNS3 and VirtualBox on my Linux system should also be usable on computers running either Windows or Mac OS. Access to hardware virtualization support makes very noticeable improvement in performance. VirtualBox can also utilize the hardware virtualization support technologies available on most computers while Qemu can only access these features in the Linux operating system (via KVM), with restrictions. Many users of GNS3 choose to use VirtualBox to run Linux virtual machines because, like GNS3, it works the same on Windows, Mac OS, and Linux operating systems. Next, we need to install software to support running the Linux virtual machines that will be managed by GNS3. Next I installed the virtual PC simulator program, vpcs which is in the same PPA:.$ sudo apt-get install snmp-mibs-downloader wireshark-doc I noticed the installer recommends two other packages be installed but does not install them because they are optional, so I installed them:.Installing the GNS3 package also installs most supporting software. Install GNS3 package from new, updated PPA repository.Add the GNS3 PPA to the Xubuntu software repository.To install the latest version of GNS3, Dynamips, Qemu, and Wireshark, do the following: GNS3 can be installed using the Ubuntu Software Center but the version available in the standard Ubuntu repositories is not the latest version of GNS3. Procedures to install GNS3 in Windows or Mac OS are available in the GNS3 documentation. This procedure describes how to install GNS3 and its supporting software on a Linux host computer running Xubuntu 13.10. In this post, we show how to install and set up GNS3 and VirtualBox to emulate a network consisting only of open-source routers and hosts. While there are many web sites and online tutorials dedicated to using GNS3 to emulate Cisco networks and Juniper networks, I found only a small amount of information about using GNS3 to emulate a network of Linux virtual machines running open-source routing and switching software. Our interest is to emulate networks of open-source routers and switches using open-source technologies. GNS3 also supports other hardware emulation and virtualization technologies that can run Linux virtual machines: Qemu and VirtualBox. GNS3 supports Cisco router software images running on the Dynamips hardware emulation program. GNS3 is primarily used to emulate networks of Cisco routers and is used by professionals studying for Cisco certification exams. GNS3 is a very popular network simulation tool that runs on the major operating systems: Windows, Mac OS, and Linux. ![]()
