Internet-detector is an application for checking the availability of the Internet. Performs periodic connections to a known public host and determines the actual Internet availability.

**Features:**
 - It can run continuously as a system service or only in an open web interface.
 - Checking the availability of a host using ping or by connecting via TCP to a specified port.
 - LED indication of Internet availability.

 - Performing actions when connecting and disconnecting the Internet: rebooting device, restarting network or modem (internet-detector-mod-modem-restart), executing custom shell scripts.
 - Sending email notification when Internet access is restored (internet-detector-mod-email).
 - The daemon is written entirely in Lua using the luaposix library.

**Dependences:** lua, luaposix, libuci-lua.
