Hi there --

I need to reconfigure yum on one of our centos 5.3 systems in order for the automatic updates to work. Currently the error messages that I am getting are shown below:

$ sudo yum check-update Loaded plugins: allowdowngrade, changelog, downloadonly, fastestmirror, priorities, protectbase, tsflags, versionlock Loading mirror speeds from cached hostfile * base: mirrors.rit.edu * updates: mirrors.unbornmedia.com * c5-media: * contrib: mirror.atlanticmetro.net * centosplus: mirror.atlanticmetro.net * addons: mirror.highspeedweb.net * extras: mirror.anl.gov file:///media/CentOS/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] No such file or directory: '/media/CentOS/repodata/repomd.x ml' Trying other mirror. file:///media/cdrecorder/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] No such file or directory: '/media/cdrecorder/repodata/ repomd.xml' Trying other mirror. file:///media/cdrom/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] No such file or directory: '/media/cdrom/repodata/repomd.xml ' Trying other mirror. Error: Cannot retrieve repository metadata (repomd.xml) for repository: c5-media. Please verify its path and try again

What file(s) do I need to modify in order to fix this issue, and also what are the correct URL's to have in place? Thanks.
