GNS3 is a network software emulator that simulates complex networks using virtual machines, routers and switches. By installing GNS3 on OpenSUSE, you can create virtual network topologies for testing and learning purposes. In this tutorial, we'll guide you through the installation of GNS3 on OpenSUSE, step-by-step.
Open the terminal on your OpenSUSE system by using the keyboard shortcut CTRL + ALT + T.
Update your system packages by running the following command:
sudo zypper update
Install the dependencies required by GNS3 by running the following command:
sudo zypper install gcc gcc-c++ kernel-devel make qt5-qtbase-devel qt5-linguist rpmbuild libpcap-devel wireshark-devel
Download the GNS3 installation file from their website by running the following command:
wget https://github.com/GNS3/gns3-gui/releases/download/v2.2.25/GNS3-2.2.25.AppImage
Note: The version of the installation file may be different. Please check the latest version on the GNS3 website before downloading.
Make the downloaded file executable by running the following command:
chmod +x GNS3-2.2.25.AppImage
Move the downloaded file to the /opt/ directory by running the following command:
sudo mv GNS3-2.2.25.AppImage /opt/
Create a symbolic link for the GNS3-2.2.25.AppImage file by running the following command:
sudo ln -s /opt/GNS3-2.2.25.AppImage /usr/bin/gns3
Finally, start GNS3 by running the following command:
gns3
In this tutorial, we've covered the step-by-step installation of GNS3 on OpenSUSE. With GNS3 installed, you can create virtual network topologies for testing and learning purposes on your OpenSUSE system.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
