Their file should work too.  You may wish to add some of their mirror
servers to your yum.conf so if the main servers are busy, you hit one of
the mirrors automatically.  To do that, simply add the URL to "baseurl="
equate, but DON'T add "baseurl=" to it.  In other words, to have two
servers:

	baseurl=http://www.fedoralegacy.org/download.....
	        http://mirror.server.tld/somedirectory...

It is very important to ONLY have the "baseurl=" on the first server.
If you put it on the mirrors, it'll confuse yum.  I do this for my 
FC1/FC2 systems.  I have one main and up to four mirrors.

Well, not really.  localhost.localdomain ties to the IP address
127.0.0.1 over the loopback interface, "lo".  While it's better to have
a "real" hostname, it's not absolutely necessary.

The odds are that your laptop isn't picking up the DNS service, so a
hostname won't resolve to an IP address.  If you can ping outside 
addresses but not hostnames, then that's your problem.  To confirm it,
try doing something such as "dig www.redhat.com" and see if you get a
response.  If not, then DNS is not set up.  Make sure the laptop's
/etc/resolv.conf file looks like your desktop machine's file.
