Automatic reboot of the 3G modem.

Not quite to refer to Web programming more to the bash script Linux server and Python language. But quite useful for remote systems. The script controls whether there is the main internet if it fails to switch to the modem. If the modem is dependent, it will recharge the device. When the main channel appears, the modem will be turned off and switch to it. He logs all his actions and can be viewed from a distance through the Web.
