Hi folks, here is the exact interaction for the last
advice from William:

---------------------------------
[root]# export http_proxy=http://llproxy.llan.mit.edu:8080
[root]# set |grep http
HTTP_PROXY=http://llproxy.llan.mit.edu:8080
http_proxy=http://llproxy.llan.mit.edu:8080
[root]# /usr/sbin/up2date -u

Fetching package list for channel: fedora-core-1...

Fetching 
http://download.fedora.redhat.com/pub/fedora/linux/core/1/i386/os//headers/header.info...
There was some sort of I/O error: <urlopen error (-2, 'Name or service 
not known')>
[root]#

Any other thoughts?
