I already had thos rsa files (I think I had to generate them to be
allowed to edit the Python docs), but I didn't know what they were for.

Now I've make authorized_keys files on both my machines with the others'
id_rsa.pub contents---and it works a treat, ssh with no passwords:-D

One last question though: how do I use names instead of IP addresses so
I can write
    ssh percival
instead of
    ssh 192.168.2.3
etc?

Thanks!
