Making IOS Devices Faster with GNS3 Server and IOU Images on a SUSE PC

You can make your IOS devices work much faster by using the GNS3 Server on your Linux computer. Plus, you can create more complicated network plans by using exceptional IOU images in the GNS3 VM.

Once you’ve added it to VMware Workstation, Fusion, or VirtualBox and turned it on in your GNS3 program, you can start adding network devices to the virtual server and keep working.

Configuring GNS3 VM on SUSE

To get the GNS3 VM up and running on your openSUSE Leap 15 computer, you’ll need to install both GNS3 and VMware Workstation programs. Then, you can follow this video tutorial or the steps below to complete the installation.

  1. To set up the GNS3 Virtual Machine on your computer, first, go to this website, where you can find the files you need. Look for the OVA file that works with VMware and download it. This file has everything you need to install the GNS3 Virtual Machine on your Linux system quickly.
  2. Just go to where you saved the download, then open the terminal. To unlock all their features, use the command “unzip” to unzip them.
  3. To get going, open the app and find all your virtual machines easily. Click on “File,” then “Open,” and choose the VM.ova file. That’s it!
  4. When the Import Virtual Machine window pops up, you can keep the installation location as it is, which is the default location. Just make sure it’s right, then click on the Import button to start bringing in the files. That’s all you need to do!
  5. After you’ve imported the GNS3 server, the next thing to do is to run it. This lets you check if the network is working by sending a ping request to the correct IP address. This helps make sure everything’s running smoothly and there are no problems that could slow down your network.
  6. Start building your network by opening the GNS3 software and choosing the ‘Run appliances in a virtual machine’ option from the Setup Wizard window.
  7. Set up the host binding by entering the server’s IP address. That’s all you need to do!
  8. Choose the virtualization software you want to use in its settings. Then, adjust the settings for the processor and memory.
  9. When your GNS3 virtual machine connects successfully, close the wizard.

How to Add Router IOS in openSUSE
