With the SSH button application you can send ssh commands to linux hosts via a button on your android device.
Simply create a new button and add the command you want to sent to the linux device.

You can specify per button:
- Label ( e.g. reboot raspberry or start application )
- Command to sent ( e.g. sudo reboot or sudo service httpd restart)
- ip adres or hostname
- username
- password
- Private key ( optional )
- ssh port

Keep in mind that you only use Linux/Unix commands that return immediately!!
