Hmm no I didn't know about that; it's good to know there
are lots of people who have made that mistake; and molly-guard
is a simple fix.
While ssh is probably the commonest way of making this mistake,
these days there are lots more ways of doing the same thing:
* KVMs (although c-a-d normally are the source of pain there)
* VNC
* IP connected KVMs
* remote X sessions
* Management consoles for large systems
* serial consoles.
* virtual machine consoles
At least some of these are entirely transparent to the OS on the
machine.
