Kelvin, This is happening because only a few sites are allowed to rsync to the official CentOS DVD mirror. Many tier 1 mirrors, like mirror.ncsa.illinois.edu, are having to mirror their DVD images from other tier 1 mirrors, rather than directly from the CentOS official DVD mirror. So, you will see some variance in the DVD ISOs. -Bill ----- Original Message ----- > I help maintain a private mirror for my company.
