![]() So, I decided to start my work with the UNetLab/EVE-NG network emulator by using the latest version, EVE-NG, even if it is still in alpha. Any changes made to the EVE-NG user interface and any new EVE-NG features will not be back-ported to UNetLab. Any problems found in UNetLab will be only fixed in EVE-NG. However, the developers have stopped developing UNetLab. ![]() In addition to updating and re-working the software, the developers changed the project’s name.Īt the time I wrote this post, UNetLab and EVE-NG are still very similar. ![]() Why EVE-NG instead of UNetLab?ĮVE-NG is the new version of UNetLab. For users of other operating systems, the EVE-NG development team provides good information on setting it up on Windows ( Setup, Integration) or Mac OS ( Setup, Intergration). In this post, I focus only on the specific issues related to getting EVE-NG working on a Linux system. Since it runs in a virtual machine, EVE-NG may be set up on any operating system such as Windows, Linux, or Mac OS. They are also developing an EVE-Cloud hosted solution that (I assume) will allow users to pay for access in exchange for a hosted solution on a remote cloud server. At the time this post was written, the EVE-NG developers are raising funds to support ongoing EVE-NG network emulator development. It runs commercial network device software on Dynamips and IOU and runs other network devices, such as open-source routers, on QEMU.ĮVE-NG is an open-source project and the EVE-NG source code is posted on GitLab. Advanced users or administrators may add software images to the library and build custom templates to support almost any network scenario.ĮVE-NG supports pre-configured multiple hypervisors on one virtual machine. Users may create network nodes from a library of templates, connect them together, and configure them. Test EVE-NG with a simple network emulation scenarioĮVE-NG is a clientless network emulator that provides a user interface via a browser.Add to the EVE-NG VM the images you will use to emulate network nodes.Modify the EVE-NG VM’s network interfaces configuration file and restart the VM.Start the EVE-NG VM for the first time and run through the automatic setup script.Modify the permissions of the VMware virtual interfaces on the Linux host computer.Set up Telnet, VNC, and Wireshark to work with EVE-NG.The steps requires to set up the EVE-NG (or UNetLab) virtual machine on a Linux host computer are: The procedure is the same for UNetLab.įor users of other operating systems, the EVE-NG development team provides good information on setting it up on Windows ( Setup, Integration) or Mac OS ( Setup, Intergration). I’ll also show the basic steps to creating and running a simple lab consisting of emulated Linux nodes. When using the EVE-NG virtual machine on a Linux computer, I had to resolve a few problems related to the way VMware Player works in Linux. ![]() Its graphical user interface runs in a web browser. The UNetLab/EVE-NG network emulator runs in a virtual machine so it can be set up Windows, Mac OS, or Linux computers. UNetLab is the current, stable version of the network emulator and EVE-NG is an updated version of the same tool, available as an alpha release. In both cases the vncviewer was giving me a black screen.EVE-NG and UNetLab are graphical network emulators that support both commercial and open-source router images. Obviously, in the case of starting x11vnc I am unsure how to map the port (-p 5900:5900). Just being paranoid I have also tried manually starting x11vnc. So technically it doesn't seem that I need to launch the xserver from within the container, as GNS3 will take care of it following the process above. A limitation of this, is that any container can access the X socket of other containers." You don’t need to modify your container to get VNC support. After that this X server is exposed to the network via X11VNC. Behind the scenes, GNS3 will start a fake Xserver (using Xvfb) and inject it in the container. "You can launch graphical programs if you choose VNC as the console type. However, when the same container runs from with GNS3 environment I get a black screen on VNC. In this way it is possible for me to use vnc to that container. I have tested the container in Ubuntu 20.4 and it works fine and I can access it if I give:Īnd then from within the container I give: ![]() RUN apt install -y x11-apps x11vnc xvfb firefoxĪs you can see I want to be able to run firefox from GNS3. ![]()
