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

Installing YalerTunnel on Debian

Follow these steps to install YalerTunnel on the CuBox.

This tutorial is still in beta. Found a bug? Let us know.

  1. Open a shell on your CuBox (default login is root, password 1234), or type
    $ cd ~
  2. Update apt-get with
    $ sudo apt-get update
  3. Download and install libssl with
    $ sudo apt-get install libssl-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.src.tar.gz
    $ tar xfzmv YalerTunnel2.src.tar.gz
    $ ./configure && make
  6. Done. Now either enable Web access or SSH access.


Web access

Prerequisites

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

Enabling Web access on Debian

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

  1. Download and install runit with
    $ sudo apt-get install runit
  2. Create a yalertunnel service directory
    $ sudo mkdir /etc/service/yalertunnel
    $ cd /etc/service/yalertunnel
  3. Download the yalertunnel run script and make it executable
    $ sudo wget http://s3.yaler.net/cubox/run
    $ sudo chmod a+x run
  4. Download the yalertunnel finish script and make it executable
    $ sudo wget http://s3.yaler.net/cubox/finish
    $ sudo chmod a+x finish
  5. Open the run script with
    $ sudo nano /etc/service/yalertunnel/run
    Check the path (default: /root/yalertunnel), set the port of the local Web service (default: 80), and set your relay domain
    1 #!/bin/sh
    
    6 exec /root/yalertunnel/yalertunnel server 127.0.0.1:80 try.yaler.io:80 RELAY_DOMAIN -min-listeners 1 </dev/null 2>&1 | logger -t yalertunnel

    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.

  6. Reboot your CuBox to run the script
    $ sudo reboot
  7. 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 Debian

How to remove YalerTunnel to disable Web access from anywhere.

  1. Open a shell on your CuBox and type
    $ sudo sv stop yalertunnel
    $ sudo rm -r /etc/service/yalertunnel
    $ sudo reboot


SSH access

Prerequisites

The SSH daemon sshd is running (per default) on the CuBox.

Enabling SSH access on Debian

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

  1. Download and install runit with
    $ sudo apt-get install runit
  2. Create a yalertunnel-ssh service directory
    $ sudo mkdir /etc/service/yalertunnel-ssh
    $ cd /etc/service/yalertunnel-ssh
  3. Download the yalertunnel run script and make it executable
    $ sudo wget http://s3.yaler.net/cubox/run-ssh -O run
    $ sudo chmod a+x run
  4. Download the yalertunnel finish script and make it executable
    $ sudo wget http://s3.yaler.net/cubox/finish
    $ sudo chmod a+x finish
  5. Open the run script with
    $ sudo nano /etc/service/yalertunnel-ssh/run
    Check the path (default: /root/yalertunnel), set the port of the local SSH service (default: 22), and set your relay domain
    1 #!/bin/sh
    
    6 exec /root/yalertunnel/yalertunnel proxy 127.0.0.1:22 try.yaler.io:80 RELAY_DOMAIN </dev/null 2>&1 | logger -t yalertunnel-ssh

    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.

  6. Reboot your CuBox to run the script
    $ sudo reboot
  7. Done. Now access your device with Putty or with SSH (for Linux, Mac OS X).

Disabling SSH access on Debian
