Hmmm I seem to have a catch22 here. I've found the page at http://www.centos.org/modules/news/article.php?storyid=118 that discusses installing yum-pluging-fastestmirror I quote: "*How do I get this new system?* This system is now live. If you update your system with the normal *yum update* command you will get the new *centos-yumconf* package." The thing is, yum update fails with a string of [errno 4] (socket time outs) and [errno 12] (mirror url timeouts) Can I get the file some other way?

The up2date issue happened because of a bug with handling obsoletes ... which is fixed in an update :P also ... header issues normally mean you need to clean your yum cache .... yum clean cache
