Solutions like Teamviewer, VNC, or XRDP can provide remote access to a Raspberry Pi over the Internet. A few extra configuration steps are required to make them work from anywhere, but it’s doable.

The small footprint and low energy demands of Raspberry Pi make it ideal for remote deployment, and accessing Raspberry Pi from another computer is a common user request.

There are many different solutions for remote access to Raspberry Pi. The most common is to use one of two techniques: SSH and VNC.

SSH and VNC involve opening a port on Raspberry Pi (VNC uses port 5900+N and SSH uses port 22). This potentially exposes your Raspberry Pi. Hackers actively look for Raspberry Pi devices with these open ports and default passwords. This is why you must change your password when turning on VNC.

Una vez instalado vamos a asegurarnos el acceso remoto para no tener que necesitar de un monitor y un teclado y ratón y podamos manejarlo.

Welcome to part 3 of the Raspberry Pi tutorial series. In this part, we're going to cover how we can remotely access our Raspberry Pi, both with SSH and with a remote desktop client. We want to eventually be able to remotely access our Raspberry Pi because much of the "value" of the Raspberry Pi is its size, and that it can be put in a variety of places that we might not want to have a keyboard, mouse, and monitor attached to it at all times and we probably don't want to have to carry over all of this stuff when we do want to access it.

Bienvenido a la parte 3 de la serie de tutoriales de Raspberry Pi. En esta parte, vamos a cubrir cómo podemos acceder remotamente a nuestra Raspberry Pi, tanto con SSH como con un cliente de escritorio remoto. Queremos eventualmente poder acceder remotamente a nuestra Raspberry Pi porque gran parte del “valor” de la Raspberry Pi es su tamaño, y que se pueda poner en una variedad de lugares que no queramos tener un teclado, ratón y monitor conectados a él en todo momento y probablemente no queramos tener que llevar todo esto cuando queramos acceder a ella.

The Raspberry Pi 3 comes with an on-board 802.11n Wireless LAN adapter, which means that it’s no longer necessary to purchase a separate WiFi dongle. It’s also quite a bit easier to set up. In this tutorial, I’ll show you how to set up WiFi from the command line or from the Raspbian desktop.  

You will need access to the Pi’s command prompt or desktop. If you have a monitor and keyboard, that’s as simple as plugging everything in. If you don’t have a keyboard and monitor and are setting up the Pi headless, check out this guide to see how to access the command prompt from another computer.
