	Note the other posters' comment re: using the hostname in the
loopback line (127.0.0.1 is referred to as the "loopback" device and is in
place to allow binding of clients, protocols, applications, etc without
using a "real" network connection - it's essential for other network things
to function in most cases)  If you're using a static IP (or an IP as
reserved in your DHCP server) for this machine you'd be best to create a
line entry for it in /etc/hosts.

	I have that book and it's good, but don't read it after a warm glass
of milk or a turkey sammich as you may never come to.  Someone else might
have a suggestion for another printed volume that's more "fun" - but you
might be best served by looking at resources on line (read: the linux
documentation project).
