SSH access

It is also possible to access your BeagleBone with SSH (Secure Shell). A Secure Shell will allow you to run all sorts of terminal-based programs, such as Kismet for wireless device monitoring or Wireshark for network monitoring.

In order to install SSH access, we must perform the following steps:

1. Download the yalertunnel-ssh.service startup script:

   $ curl -L http://yalertunnel.s3.amazonaws.com/yalertunnel-ssh.service -o /lib/systemd/system/yalertunnel-ssh.service
   

2. Create a symbolic link:

   $ ln -s  /lib/systemd/system/yalertunnel-ssh.service /etc/systemd/system/multi-user.target.wants/yalertunnel-ssh.service
   

3. As with the web interface, we must edit the script to set YOUR_RELAY_DOMAIN, the local IP (default: localhost), and port (default: 22) of the local SSH service that you want to make accessible via Yaler.

   $ nano /lib/systemd/system/yalertunnel-ssh.service
   
   [Unit]
   Description=yalertunnel on port 22
   ConditionPathExists=|/home/root/yalertunnel
