Re: Recovering by failsafe: connection lost after ~30 sec

This was clear to me, but what changed the IP? Perhaps a behaviour of the network manager? (I'm on Debian 7.6).

Any way, eager to look into the box, I tried with another machine. Ok with the failsafe, but the situation appears quite bad. I'm afraid the last resource is to reflash the factory firmware and then start everything again...

Same story for /opt and /etc/config...
