Installation

netsim-tools is available as a Python3 package that runs on most systems supporting Python3. It’s been tested with Python 3.9, but should run on older Python3 versions.

The lab control functionality uses Ansible playbooks, and thus works only on systems supported by Ansible. It’s recommended to use Ansible 2.9 or higher.

Installing a Python Package

Use python3 -m pip install netsim-tools to install the software. The installation process will install all prerequisite Python packages (but not Ansible) and create the netlab command.

Installing from GitHub

  • Clone the netsim-tools Github repository.

  • If needed, select the desired release with git checkout release-tag. Use git tag to get the list of release tags.

  • Within the netsim-tools directory, install prerequisite Python packages with python3 -m pip install -r requirements.txt.

  • Optional: install Ansible or use ipSpace network automation container image.

  • Add netsim-tools directory to your PATH with source setup.sh command

Complete Ubuntu VM/Server Installation

If you’d like to use netsim-tools with libvirt1, and would like to create a Ubuntu VM from scratch, follow the tutorial created by Leo Kirchner.

If you want to install netsim-tools and all its dependencies on an existing Ubuntu server (bare-metal or VM):

  • If needed, install pip with sudo apt-get update && sudo apt-get install -y python3-pip

  • Install netsim-tools package1 with sudo python3 -m pip install netsim-tools

  • Install additional software with netlab install ubuntu ansible libvirt command (more details)

1 Yes, I know one should install Python packages into a virtual environment, but hopefully we’re either talking about a throwaway VM, or you know what you’re doing.

Building the Lab Environment

The libvirt Vagrant plugin starts all network devices in parallel, resulting in much faster lab setup than using Vagrant with Virtualbox.
