How to Setup VyOS (Virtual Router Pentest Lab)

VyOS is a Linux-based network operating system that provides software-based network routing, firewall, and VPN functionality.  Its configuration syntax and command-line interface are loosely derived from Juniper JUNOS as modeled by the XORP project.

First Download Vyos iso image from here

Open VMWARE tool, create a new virtual machine. Select Installer disc image file and select OS image of vyos and click on next.

Enter your virtual machine name and location. Click next.

Set Ram upto 1 GB for vyos and click to network adapter

Next we are choosing our first network adapter. Connect it to the Bridge Adapter and click on close.

Then click on finish.

Now installation process will start automatically. It takes a few seconds for the VM to boot and VyOS to load.

After boot screen hit enter and login to vyos using following credentials:

Username : vyos

Password : vyos

Installation of Vyos on local disk. In order to do that simply execute command: install image and press enter

Now type yes and press enter in next option Select auto partition press enter

In next option type yes to continue press enter

After the installation is complete Issue the reboot command Again type: yes press enter

Login again to vyos and we will start with setting

Now we will check network interfaces using show interfaces command

Now Enter configuration mode by typing “conf” and have a look at the current interfaces:

After you made some changes, you need to enter the “commit” and “save” commands.

Now we will setup network interfaces:

set interfaces ethernet eth0 address dhcp

Now again you need to enter the “commit” and “save” commands. Now we will check network interfaces using run show interfaces command.

Now before we are able to connect to our router with SSH, we will enable SSH In order to do it execute following commands:

 set service ssh Commit and save.

Now before we are able to connect to our router with TELNET, we need to enable that. To do so, issue the following commands

set service telnet Commit and save

To check all enable service type the following command

Show service
