Internet connectino Watchdog

this is about creating a raspberry pi based appliance that monitors your internet conenction and if it goes down, automatically debugs it and restarts stuff like modem / router etc. as necessary. the device should also be reachable via an on-demand gsm link that can be initated by sms to login to the device and debug the link manually

so far, this is just a collection of snippets of information and links, i'll write it up into a nice article one day, but not today ;)

  • Software: Gammu
  • Hardware: TP-Link MA260
  • on the tp-link stick the last serial device seems to be the one that can be used for sms (gammu identify only gets information from that device).
    gammu-detect | grep -B1 TP-LINK | grep ttyUSB | tail -n 1

    to get the device name for the config

  • installation:
    apt install gammu gammu-smsd
  • See above
  • via dual prolific basead usb to serial converter, one link goes to the relay card, the other to the serial terminal of the pfsense router.
  • usb link is extended down to the basement via cat7 link, I simply cut a usb extension cord into two and attached RJ45 plugs to both ends with identical pin layout. works like a charm :)
