typo to prison

[Alex Fraser]

I've got 4 Raspberry Pi's running headless and I'm using a Linux Mint 
machine as my control station.  I'm getting the hang of Bash scripts, 
though what runs where is still confusing.  Late  last night I decided 
to shut down everything, so of course decided to write a script to go 
through each Pi and shut it down.

a line of the code

ssh pi at pi2.host  shutdown -h now

this of course should have been

ssh pi at pi2.local  shutdown -h now

When I ran the first one it seemed to do nothing.  I had shared a key 
with all my Pi so as to not have to use a password.  I exited and ran it 
again waiting a bit longer.  I got a not invalid key error and an IP4 
address out on the real internet.  I just hope I haven't popped up on 
some terrorist list as trying to shutdown some part of the grid.  I 
wonder how often things escape onto the net like that?
