Instructions and extensions for the comnetsemu network emulator

Instructions for easy comnetsemu installation

The following are the suggested and fastest ways to run comnetsemu VM.

A. Running comnetsemu in VirtualBox

The simplest way to enjoy comnetsemu is to:

1) install VirtualBox in your system

2) download and import in VirtualBox the comnetsemu stand alone ova package

3) run the VM in VirtualBox

4) connect locally to the VirtualBox via ssh (username: comnetsemu, password: comnetsemu)

[more detailed information will soon follow]

B. Building and running comnetsemu using multipass

1) Download and install multipass for your system

2) Run the following commands in the host terminal to generate and connect to the multipass VM:

multipass launch 20.04 --name myVM

multipass shell myVM

3) Run the following commands in the multipass VM:

sudo apt update

sudo apt upgrade

sudo apt install git iperf iperf3 make pkg-config python3 python3-dev python3-pip sudo ansible

git clone

cd comnetsemu/util/

bash ./ -a

4) The system should be ready to go. Try "sudo mn" to run mininet in the simplest configuration.

Note: This is currently the best way to run comnetsemu in Apple Silicon (M1 & beyond) platforms.

C. Continuously updated comnetsemu install using vagrant

Please refer to the official installation instructions for this.

Note: vagrant install requires some basic knowledge about git repositories and virtualization.

Extensions for the comnetsemu network emulator

As the popularity of our comnetsemu network emulator grows, so also its applications!

In this webpage, we are collecting the most interesting extensions of comnetsemu. Those are not directly included in the official repository since not all users might be interested on those, and that otherwise the package would become too cumbersome.
