Prerequisites

To complete this tutorial, you will need:

• A laptop running Linux or MacOS. for this tutorial I will be using a laptop running Ubuntu 16
• A console cable. Since all the new laptops today don't come with a USB port, you will need a USB to Console adapter
• The program "Screen"

If you don't have "screen" install it with the command below

sudo apt-get install screen

Accessing the device

• Step 1: Plug the console cable to you device into the console port and start screen as root user on your laptop

screen ttyUSSB0

• step 2: Power on your device

• Step 3: Enter the username and password

How to setup the root password

When you come from a CISCO world like me, at the beginning it is a little bit confusing when working with JunOS. But, with time running a couple of commands, you get use to the concept.
