This didn't work because you've clearly missed the actual arguments to
the command when copy/pasting... You've only done "ssh -vvv" which was
never going to work when you needed "ssh USER@HOST".

Where did this come from?! It's "systemd". Typographical rather than
technical nitpick but all the same.

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.

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.

Unfortunately Neil has managed to lock himself out of his router and
needs to either reset it or break into it... Also, that sounds like a
very slow and cumbersome way of doing a port scan.

nmap -v -sP | grep -v down

Linux has the tools for absolutely everything you can think of including
a quick subnet probe, don't make things hard for yourselves!

Yeah, I sometimes have weird duplicate email issues with this list (and
only this list) but I can't be bothered to do anything about it,
especially as it seems to have stopped recently.
