This directory (and version of CentOS) is depreciated. For normal users, you should use /5/ and not /5.6/ in your path. Please see this FAQ concerning the CentOS release scheme: www.centos.org - FAQ - General CentOS Questions - What is the versioning/release scheme of CentOS and how does it compare to the upstream vendor? If you know what you are doing, and absolutely want to remain at the 5.6 level, go to Index of / for packages. Please keep in mind that 5.6 no longer gets any updates
