    Can you try the update again? Maybe it was a temporary problem. Also make sure you have valid name servers in /etc/resolv.conf.

    Thanks for reply

    Update still wont work.

    looked at the /etc/resolv.conf should the ip address be the same as i logged into the server box? or should it be the fixed ip address given to my by my isp? I was given 2 ip addresses

    Use the IP addresses of your ISP.
    What's in /etc/resolv.conf now?

    Sorted it out now.. What i did was a usr/sbin/netconfig set it to Use dynamic ip configuration
    i checked the /etc/resolv.conf did some thinking
    Then back to usr/sbin/netconfig and put my fixed ip addess and worked it out from there

    And now i am happy updating :)

    You may have a DNS issue. Try to ensure you can resolve DNS records locally:

    nslookup google.com

    If you get an IP back from that command, you should be OK for DNS. Try then removing the fastestmirror cache and re-running your yum command:

    rm -f /var/cache/yum/timedhosts.txt
