You walk over to the location of the computer, plug in a keyboard and a
monitor, log on as root, and alter the hosts.allow file.
Whenver you change something critial like that, always test BEFORE loggin
off as root so you can correct your errors. This is especially true if the
location of the computer is miles from where you are, or is sealed in a
concrete tomb.
