I, too, would like to know why your domain name did not get set during
installation. I've always had the opportunity to do so, ever since Red
I believe it is possible, though, to select that your domain name should
be set via DHCP. Not all DHCP servers will send that information, and if
you have one of those, then your domain name will not get set.

You appear to misunderstand the purpose of localhost.
Localhost is always supposed to mean *this* computer. It is supposed to
point to the loopback interface, which is normally 127.0.0.1. That
doesn't correspond to your Ethernet card, or your modem, or your Token
Ring card, or your carrier pigeon interface. It is for use when you want
to send TCP/IP messages, and know that they will be responded to by a
service running on *this* computer.
I can log onto a Fedora box, and a SUSE box, and an AIX box, and even a
Windows 2000 box, and ping localhost, on all of them does the same
thing: it confirms that the internal loopback network device is up.
No well-configured computer will ever use localhost to refer to another
one. It is, as you say, useless on networks of more than one PC. But
that's not what it's there for.
Hope this helps,
