Software dependencies

In addition of Python dependencies listed in a section below, other software may be required, recommended or optional.

  • uBridge is required, it interconnects the nodes.
  • Dynamips is required for running IOS routers (using real IOS images) as well as the internal switches and hubs.
  • VPCS is recommended, it is a builtin node simulating a very simple computer to perform connectitivy tests using ping, traceroute etc.
  • Qemu is strongly recommended on Linux, as most node types are based on Qemu, for example Cisco IOSv and Arista vEOS.
  • libvirt is recommended (Linux only), as it's needed for the NAT cloud.
  • Docker is optional (Linux only), some nodes are based on Docker.
  • mtools is recommended to support data transfer to/from QEMU VMs using virtual disks.
  • i386-libraries of libc and libcrypto are optional (Linux only), they are only needed to run IOU based nodes.

The following commands will install some of these dependencies:

Finally these commands will install the server as well as the rest of the dependencies:

To run tests use:

Docker container

For development you can run the GNS3 server in a container

Run as daemon (Unix only)

You will find init sample scripts for various systemsinside the init directory.

Usefull options:

  • --daemon: start process as a daemon
  • --log logfile: store output in a logfile
  • --pid pidfile: store the pid of the running process in a file and prevent double execution

All init scripts require the creation of a GNS3 user. You can change it to another user.

upstart

For ubuntu < 15.04

You need to copy init/gns3.conf.upstart to /etc/init/gns3.conf

systemd

You need to copy init/gns3.service.systemd to /lib/systemd/system/gns3.service

Windows

Please use our all-in-one installer to install the stable build.

If you install via source you need to first install:

  • Python (3.3 or above) - https://www.python.org/downloads/windows/
  • Pywin32 - https://sourceforge.net/projects/pywin32/

Then you can call

to install the remaining dependencies.

Describe the bugGNS3 starts fine but the GNS VM indicator does not turn green.

GNS3 version and operating system (please complete the following information):Windows 10 Pro Version 1909 (OS Build 18363.778)Running GNS3 version 2.2.7 on Windows (64-bit) with Python 3.6.8 Qt 5.12.1 and PyQt 5.12.Copyright (c) 2006-2020 GNS3 Technologies.

  • Any use of the GNS3 VM or remote server (ESXi, bare metal etc.)VMware┬« Workstation 15 Pro 15.5.2 build-15785246

To ReproduceSteps to reproduce the behavior:Start GNS3. Wait for GNS3 VM to be fully started. Click on GNS3 menu to open an existing project.

Screenshots or videosIf applicable, add screenshots (e.g. of the topology and/or error message) or links to videos to help explain the problem. This will help us a lot to quickly find the bug and fix it.

Additional contextSo far, the only fix is to close GNS3, thus closing VMware Workstation, doing a repair for VMWare Workstation (reset all VMware virtual nics to their default values) and running vmnet-manager.cmd.GNS3 then works fine until I close it, restart my workstation and try to run it again.
