Following the brainfart with trying to send emails when the power is cut (router and modem *not* on UPS), I had this idea that it should be relatively easy to hook a cheap mobile phone, with a PAYG SIM upto the server and send text alerts when power goes.
This is just for fun - no operational life or death requirements.
Seems there's a Linux package called SMSD, which can control a GSM phone via a serial cable.
So really it's a question of using a phone which can be charged via the USB connection. I'm pretty sure my old Nokia 5800 doesn't charge via USB, as it has it's own separate socket.
Comments anyone ?
