Thank you for the quick reply.
I replaced my yum.conf file with yours and when I run yum update I receive the following:
Gathering header information file(s) from server(s)
Server: Test Linux 2.6-test prerelease kernels for RHL9/rawhide
retrygrab() failed for:
Executing failover method
failover: out of servers to try
Error getting file http://people.redhat.com/arjanv/2.5/headers/header.info
[Errno 6] ERROR: Url Return no Content-Length - something is wrong
I'm behind a proxy server but I'm able to access the Net just fine with Mozilla. Is there something I need to put in the yum.conf file to indicate the presence of a proxy server?
