dag.repo overwritten I accidentally overwrote dag.repo by trying to add this [dag] name=DAG RPM Repository baseurl= gpgcheck=1 enabled=1 does anyone have the backup file for dag.repo which is found in /etc/yum.repos.d for centOS 5.8 or where can I download it?

The repo definition does not come with CentOS. But Dag's repo is mostly obsolete at this point; you should be using Repoforge instead.
