I have made all the site changes in yum.conf and up2date for the change of URL, as listed many times on the list. I have updated /etc/sysconfig/rhn/up2date with the correct proxy and entered http_proxy="http://proxy-name:80". I When I run 'yum update' command I get the following error, Gathering header information file(s) from server(s) Server: Fedora Core 1 - i386 - Base retrygrab() failed for: http://download.fedora.redhat.com/pub/fedora/linux/core/1/i386/os/he aders/header.info Executing failover method failover: out of servers to try Error getting file http://download.fedora.redhat.com/pub/fedora/linux/core/1/i386/os/head ers/header.info [Errno 7] HTTP Error (CannotSendRequest): Any ideas?
