You've only done "ssh -vvv" which was never going to work when you needed "ssh USER@HOST". > Is it using system.d? Where did this come from?! It's "systemd". Typographical rather than technical nitpick but all the same. > Where did ethX and wifiX go https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/ We don't use crappy old kernel+udev naming conventions for interfaces anymore, they're prone to naming collisions during setup and random reallocation on hardware modification or VM/Container deployment. Similarly we don't use /dev/sdX or /dev/hdX for hard drives any more either - too dumb. We use UUIDs instead. > ifconfig This is basically deprecated now as part of the old nettools package so get used to the new "ip" command. Ifconfig will eventually die completely. https://dougvitale.wordpress.com/2011/12/21/deprecated-linux-networking-commands-and-their-replacements/ > You need to log into your router, locate all the attached devices, > write down their internal IP addresses, ping them Unfortunately Neil has managed to lock himself out of his router and needs to either reset it or break into it...
