What are their hashes? Here are some hash values of the files I'm sharing in a bittorrent client: CentOS-6.5-x86_64-bin-DVD1.iso (4,467,982,336 bytes) MD5 - 83221db52687c7b857e65bfe60787838 SHA1 - 32c7695b97f7dcd1f59a77a71f64f2957dddf738 SHA256 - c796ab378319393f47b29acd8ceaf21e1f48439570657945226db61702a4a2a1 CentOS-6.5-x86_64-bin-DVD2.iso (1,284,395,008 bytes) MD5 - 91018b86ca338360bc1212f06ea1719f SHA1 - 25e5de362ba6c75d793dbeb060b27ba1865cb5df SHA256 - afd2fc37e1597c64b3c3464083c0022f436757085d9916350fb8310467123f77 There are currently over 1000 other people sharing the CentOS-6.5-x86_64-bin-DVD1to2.torrent, too. So, do the hashes of your files match those?
