Access your Raspberry Pi from the Web

Make your Raspberry Pi accessible from anywhere via the Yaler relay.

Prerequisites

Setting up your device requires a relay domain. Please sign up to get one.

Setting up the hardware

Make sure the Raspberry Pi is connected to the Internet via Ethernet, Wi-Fi or 3G.

This tutorial is for Raspbian Stretch. Older version? See how to access Raspbian Jessie from the Web.

Installing YalerTunnel on Raspbian

Follow these steps to install YalerTunnel on the Raspberry Pi.

  1. Open a shell on your Raspberry Pi (default login is pi, password raspberry), or type
    $ cd ~
  2. Update apt-get with
    $ sudo apt-get update
  3. Download and install libssl with
    $ sudo apt-get install libssl1.0-dev
  4. Create a yalertunnel directory
    $ mkdir yalertunnel
    $ cd yalertunnel
  5. Download, unzip and build the YalerTunnel source
    $ wget http://s3.yaler.net/yalertunnel/YalerTunnel2-v2.3.0-beta.6.src.tar.gz
    $ tar xfzmv YalerTunnel2-v2.3.0-beta.6.src.tar.gz
    $ make
  6. To check the installation, display the YalerTunnel version and usage with
    $ ./yalertunnel
  7. Done. Now either enable Web access or SSH access or VNC access.


Web access

Prerequisites

A Web server or service has been installed and is running on the Raspberry Pi.

Enabling Web access on Raspbian

How to configure YalerTunnel on your Raspberry Pi to make a local Web service accessible from anywhere.

  1. Download the yalertunnel yalertunnel.service script
    $ sudo wget -O /lib/systemd/system/yalertunnel.service http://s3.yaler.net/raspi/yalertunnel.service
  2. Open the yalertunnel.service script with
    $ sudo nano /lib/systemd/system/yalertunnel.service
    Check the path (default: /home/pi/yalertunnel), set the port of the local Web service (default: 80), and set your relay domain
    1 [Unit]
    
    5 WorkingDirectory=/home/pi/yalertunnel
    6 ExecStart=/home/pi/yalertunnel/yalertunnel server 127.0.0.1:80 try.yaler.io RELAY_DOMAIN -min-listeners 1

    Save changes with CTRL-X, then Y, then RETURN. Do not change the local IP (default: 127.0.0.1), unless the Web service runs on a separate device in the same network.

  3. Enable and start yalertunnel.service
    $ sudo systemctl daemon-reload
    $ sudo systemctl enable yalertunnel.service
    $ sudo systemctl start yalertunnel.service
  4. Reboot your Raspberry Pi
    $ sudo reboot
  5. Done. Now access your device from any Web browser or with Curl or from iOS or from Android (and resolve errors).

Disabling Web access on Raspbian

How to remove YalerTunnel to disable Web access from anywhere.

  1. Open a shell on your Raspberry Pi and type
    $ sudo systemctl stop yalertunnel.service
    $ sudo rm /etc/systemd/system/multi-user.target.wants/yalertunnel.service
    $ sudo rm /lib/systemd/system/yalertunnel.service


SSH access

Prerequisites

The SSH daemon sshd is running on the Raspberry Pi.

To enable sshd on Raspbian, add a file called ssh to the boot partition of the SD card or use raspi-config.

Enabling SSH access on Raspbian

How to configure YalerTunnel on your Raspberry Pi to allow SSH access from anywhere.

  1. Download the yalertunnel yalertunnel-ssh.service script
    $ sudo wget -O /lib/systemd/system/yalertunnel-ssh.service http://s3.yaler.net/raspi/yalertunnel-ssh.service
  2. Open the yalertunnel-ssh.service script with
    $ sudo nano /lib/systemd/system/yalertunnel-ssh.service
    Check the path (default: /home/pi/yalertunnel), set the port of the local SSH service (default: 22), and set your relay domain
    1 [Unit]
    
    5 WorkingDirectory=/home/pi/yalertunnel
    6 ExecStart=/home/pi/yalertunnel/yalertunnel proxy 127.0.0.1:22 try.yaler.io RELAY_DOMAIN

    Save changes with CTRL-X, then Y, then RETURN. Do not change the local IP (default: 127.0.0.1), unless the SSH service runs on a separate device in the same network.

  3. Enable and start yalertunnel-ssh.service
    $ sudo systemctl daemon-reload
    $ sudo systemctl enable yalertunnel-ssh.service
    $ sudo systemctl start yalertunnel-ssh.service
  4. Reboot your Raspberry Pi
    $ sudo reboot
  5. Done. Now access your device with Putty or with SSH (for Linux, Mac OS X).

Disabling SSH access on Raspbian

How to remove YalerTunnel to disable SSH access from anywhere.

  1. Open a shell on your Raspberry Pi and type
    $ sudo systemctl stop yalertunnel-ssh.service
    $ sudo rm /etc/systemd/system/multi-user.target.wants/yalertunnel-ssh.service
    $ sudo rm /lib/systemd/system/yalertunnel-ssh.service


VNC access

Prerequisites

A VNC service has been installed and is running on the Raspberry Pi.

Enabling VNC access on Raspbian

How to configure YalerTunnel on your Raspberry Pi to allow VNC access from anywhere.

  1. Download the yalertunnel yalertunnel-vnc.service script
    $ sudo wget -O /lib/systemd/system/yalertunnel-vnc.service http://s3.yaler.net/raspi/yalertunnel-vnc.service
  2. Open the yalertunnel-vnc.service script with
    $ sudo nano /lib/systemd/system/yalertunnel-vnc.service
    Check the path (default: /home/pi/yalertunnel), set the port of the local VNC service (default: 5901), and set your relay domain
    1 [Unit]
    
    5 WorkingDirectory=/home/pi/yalertunnel
    6 ExecStart=/home/pi/yalertunnel/yalertunnel proxy 127.0.0.1:5901 try.yaler.io RELAY_DOMAIN

    Save changes with CTRL-X, then Y, then RETURN. Do not change the local IP (default: 127.0.0.1), unless the VNC service runs on a separate device in the same network.

  3. Enable and start yalertunnel-vnc.service
    $ sudo systemctl daemon-reload
    $ sudo systemctl enable yalertunnel-vnc.service
    $ sudo systemctl start yalertunnel-vnc.service
  4. Reboot your Raspberry Pi
    $ sudo reboot
  5. Done. Now, see how to access your device with VNC.

Disabling VNC access on Raspbian

How to remove YalerTunnel to disable VNC access from anywhere.

  1. Open a shell on your Raspberry Pi and type
    $ sudo systemctl stop yalertunnel-vnc.service
    $ sudo rm /etc/systemd/system/multi-user.target.wants/yalertunnel-vnc.service
    $ sudo rm /lib/systemd/system/yalertunnel-vnc.service
