You can enable the grid if you want things to look tidy. Essentially, this is very similar to creating a flowchart. ![]() To connect them to one another, add a link. Drag a symbol from the sidebar to the workspace to add a new interface. It has the following options: routers, switches, end devices, security devices, and links. The sidebar on the left displays the nodes (or interfaces) that you can add to the workspace in the middle. Before you begin, you will need to start a new project (to save your work). Give it a name, select where to save it and many of the options on the GNS3 client interface will become usable. The program won't function correctly until a working server is detected. You'll see the local server displayed on the right pane. You will see a dialog box and you need to wait for it to close which may take a moment. Run the client program and wait for it to connect to the server. Interface tour + Creating a virtual network Hit the import button and wait for it to complete the process. Click on open again, and choose the folder where you would like to import the virtual machine to. VMWare Player users can click on Player > Open and browse to the folder where the GNS3 VM.ova file is located. Extract the archive which the VM image comes in to a folder. Since I use VMWare Workstation Player, I used the GNS3 package which was available for it. It's available for Virtual Box, VMWare Workstatiom, VMWare Pro, ESXi anbd HyperV. This is basically an Ubuntu virtual machine. Note: However, pay attention to the final step of the installation, because there is one more optional program (Solarwinds toolset) that you can download. Npcap is required for your network cards to communicate. ![]() But then I noticed that the GNS3 client integrates these tools and you can use them directly from within the program's interface. You can uncheck any of these, though I would suggest you install them unless you know that you don't require some of them I did so for the purpose of reviewing them. The installer has quite a few third-party network tools that are pre-selected for installation. Windows users should download the all-in-one (EXE) from GitHub or SourceForge. The GNS3 client is what you use for controlling the virtual machine server and simulating the network. Installing the GNS3 client on Windows, Mac, and Linux You can download the program and the server VM from the GitHub or SourceForge pages without registration. Note: If you want to download GNS3 from the official website, you will need to register for an account, and that requires a lot of personal information. ![]() The tool consists of two parts, a virtual machine that acts as a server and a client program that you use to interact with the server and access all of GNS3's features. Now I understand at least why the GNS3 VM in GNS3 remains grey (it's because I have no reachability between my PC/host and the VM inside VMware).This open source tool can be useful for setting up a local network in an office or other environments, and also for troubleshooting purposes. The next time I booted the VM, I saw that IP, but I can't ping it from a DOS/CMD prompt. I also noticed the VM came up with an IP not in my local host's subnet, so I reserved an IP in my home Linksys router and configured that IP in the VM. ![]() I also decdided to uninstall GNS3 completely (v.2.2.6), rebooted and installed GNS3 v2.2.7 with no change (and that's with my FW and antivirus disabled still). I disabled my Windows FW and my antivirus software (MalwareBytes). Within the VMWare software, the VM itself is running and it boots up to the screen that shows a number of options: In GNS3, under Preferences, I have "Enable the GNS3 VM" checked, the virtualization engine is VMware Workstation and the VM Name dropdown shows GNS3 VM. I also see the GNS3 VM LED, but it's grey. I see the one green icon that shows the CPU and RAM usage. I'm having an issue getting the GNS3 VM icon to turn green. Hello, I'm trying to tinker with Ansible and trying to get the VMWare VM working within the GNS3 app.
