Software

Usage

Setup

Refer to Getting Started - Raspberry Pi Documentation.

Connect peripherals (e.g. mouse, keyboard, monitor) and networking (e.g. ethernet) to the Raspberry Pi, and then connect it to power, which can be supplied by a cable or directly through its header.

The Raspberry Pi may use microHDMI for video output. Adapters and cables are available.

SSH

The Secure Shell (SSH) protocol is a method for securely sending commands from your computer to the Raspberry Pi over the same network.

Refer to https://www.raspberrypi.com/documentation/computers/remote-access.html.

On the Raspberry Pi:

  1. Connect the Raspberry Pi to the internet.

  2. From the Preferences menu, launch Raspberry Pi Configuration.

  3. Navigate to the Interfaces tab.

  4. Select Enabled next to SSH.

  5. Click OK.

  6. Get the IP address of the Raspberry Pi.

    1. Use one of the methods listed here: https://www.raspberrypi.com/documentation/computers/remote-access.html#find-the-ip-address-of-your-raspberry-pi.

On your remote machine:

  1. Connect to the same network as the Raspberry Pi.

  2. SSH into the Raspberry Pi using the following command:

    ssh@[IP Address]

  3. Enter the WARG password (same as WARG Laptop).

  4. You should now see the Raspberry Pi command prompt in your terminal.

    <warg>@<[IP Address] ~ $

VNC

Virtual Network Computing (VNC) allows you to control the desktop of one device from another.
