Overview

What is GNS3 Server?

GNS3 (Graphical Network Simulator-3) is an open-source network emulator, written in Python and released under the GPL license. It allows you to design, test, and troubleshoot complex networks by combining virtual equipment with real hardware — an essential tool for training, certification preparation, and network POCs.

The gns3-server component is the engine that runs the emulation: Dynamips for Cisco IOS, IOU, QEMU and VirtualBox machines, Docker containers, as well as a wide catalog of appliances. The GNS3 graphical client (Windows, Linux, macOS) connects to it via a REST API to remotely control topologies.

Offloading this server to a powerful infrastructure frees your workstation from the CPU and RAM constraints imposed by emulation. Hosted at DINAO, your topologies, images, and configurations remain in France, on a dedicated and encrypted instance.

FAQ

You might be wondering…

What is the GNS3 server?

GNS3 (Graphical Network Simulator-3) is an open-source network emulator. The server component (gns3-server) runs the emulation; the graphical client connects to it to design and control your topologies remotely.

Why host the server at DINAO?

Network emulation is CPU and RAM intensive. By offloading the server to our infrastructure, your workstation stays lightweight and your large topologies run on dedicated resources.

What equipment can I simulate?

GNS3 is multi-vendor: Cisco via Dynamips/IOU, QEMU/VirtualBox machines, Docker containers, firewalls, and many appliances. You can also connect real equipment.

How do I connect to it?

With the GNS3 client (Windows, Linux, macOS) pointed to your server, via an encrypted connection, or via the web console depending on the configuration.

Do I need to provide Cisco IOS images?

Yes. For licensing reasons, Cisco IOS images must be provided by you. DINAO configures the emulator; you remain responsible for your software usage rights.
