[Yum] Using Yum with RedHat ES 3.0

[Rob Sullivan]

I'd like to use Yum to resolve some dependency issues on a newly 
installed RH ES 3.0 setup.  It does not appear that there's a header 
file for this distro, though Yum does look for one.  The error I get is 
as follows:

retrygrab () failed for: 
http://mirror.dulug.duke.edu/pub/yum-repository/redhat/3ES/i386/headers/header.info
failover: out of servers to try
Error getting file 
http://mirror.dulug.duke.edu/pub/yum-repository/redhat/3ES/i386/headers/header.info
[Errno 4] IOError: HTTP Error 404: Not Found

While browsing the repository, there doesn't seem to be a dir for 
anything after 9.0.  Would it be advisable to create a config file 
specifying the 9.0 dir?

Thanks,
Rob Sullivan
