I think I actually got the right file. The size of the original file should be 4,370,640,896. Previously I used Internet Explorer to see the file size in the file property. Clearly it gives a wrong number. But still we implicitely assume all mirrors sites are trustable and are properly protected. It is much better to use digital signature instead of md5sum to protect the integrity of the file. ----- Original Message ----- From: "Xinming He" <xhe@xxxxxxx> To: <fedora-list@xxxxxxxxxx> Sent: Tuesday, May 25, 2004 7:16 PM Subject: problem with FC2-i386-DVD.iso > I downloaded FC2-i386-DVD.iso from a mirror site > ftp://limestone.uoregon.edu/fedora/ using Internet Explorer.
