I downloaded FC2-i386-DVD.iso from a mirror site ftp://limestone.uoregon.edu/fedora/ using Internet Explorer. It is strange to see that the size of the file I got is 4,370,640,896, while the size of the original file is 4,294,967,295. I got the same md5sum as specified in the redhat web site. It is quite strange. Not sure if I have got the right file. It would be better if the file is protected with some digital signature instead of the simple md5sum.
