```shell
sh /root/resolver-testbed-master/config-files/setup-gateway-vm.sh
```

```shell
sh /root/resolver-testbed-master/config-files/setup-resolvers-vm.sh

Source: https://github.com/icann/resolver-testbed/blob/master/setup-and-running.md

This snippet demonstrates fetching the resolver testbed zip archive from GitHub and unzipping it within the servers-vm. It assumes the VM has internet access and the `fetch` and `unzip` utilities are available. The script `setup-servers-vm.sh` is then executed to complete the server VM setup.

```shell
fetch --no-verify-peer https://github.com/icann/resolver-testbed/archive/master.zip
unzip master.zip
rm master.zip
sh /root/resolver-testbed-master/config-files/setup-servers-vm.sh

```ansible
ansible-playbook ansible/vagrant_fast_up.yml
# or if your machine will not take it because of low number of cores
ansible-playbook -f <number lower than the default 5> ansible/vagrant_fast_up.yml
```

### VM Creation and Network Provisioning (Serial)

Source: https://github.com/icann/resolver-testbed/blob/master/auto/README.md

Standard Vagrant commands for bringing up virtual machines, fetching images, and initial network/system configuration. This method uses Vagrant's default serial execution, which can be slower for initial setup and reloads compared to the parallel Ansible approach.

```bash
vagrant up
ansible-playbook ansible/network_provision_*
# If system changes are needed after editing files:
ansible-playbook ansible/network_provision_*
# To apply system configuration changes:
vagrant up
```

--------------------------------

### VirtualBox Network Setup with Ansible

Source: https://github.com/icann/resolver-testbed/blob/master/auto/README.md
