Hi everyone At http://www.centos.org/modules/newbb/viewtopic.php?topic_id=2217&forum=6 I expressed some dismay at the fact that several of the update mirrors are broken or outdated. I also proposed some remedies for the problem. Since nobody has replied there, I thought I'd better bring the issue here. I wrote a script which checks header.info on all parts of both distributions on all update mirrors using http headers only, thus a totally negligible amount of bandwidth, and then modifies sdb_ldap DNS zone records for mirror.centos.org to only reflect good mirrors. Of course it could run against a plain vanilla BIND too, but sdb_ldap has the great advantage that it eliminates the need to reload after every zone change, so that removing bad mirrors from and re-inserting repaired ones into the round-robin can be done really often. To go along with the script, I also wrote an sdb_ldap .ldif for mirror.centos.org. Is there any interest to implement any of this? Z
