SSH passwordless authentication for Remote access: Consider using ssh-copy-id instead of cat | ssh

[tommybobbins]

When appending to the authorized_keys file, I find it easier to use the built in command:

 $ ssh-copy-id -i ~/.ssh/id_rsa.pub pi@192.168.1.137

Which gives the following output

pi@192.168.1.137's password: 
Now try logging into the machine, with "ssh 'pi@192.168.1.137'", and check in:

  ~/.ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

The advantage of this command is it has no backticks or pipes to worry about.

We'd rather just use this as well, but sadly it's not present on OS X (or I believe FreeBSD), meaning we'd have to give different instructions for OS X and for Linux.

Doh! Lovely set of documentation. Thanks.
