I just lost a server by restarting the network interfaces.
Then i got the following idea:
A small GSM device with an RS232 connector
I want to connect the serial console to the device, and in case the server gets unreachable i could call it by phone and get full access to the serial console
So here comes the question:
are there such devices?
Yup. Check out Digi’s range of products – you probably want the Digi Connect WAN. I’ve used these at colos for backup/last resort connectivitiy. They’re not particularly cheap though.
