Check iso images with md5sum

[Jman]

md5sum generates a key for files. If even the slightest bit changes, the md5sum changes. This is useful for verifying that the iso images of Fedora you downloaded are correct before burning them.

First get md5sum. This should be available on Linux systems. There is a Windows executable here (http://downloads.activestate.com/contrib/md5sum/Windows/md5sum.exe), copy it to Windows/System32

Run it on the files. Open a terminal window, cd to the iso image directory and run md5sum *.iso Then compare them against the official md5sums in the MD5SUM file from the mirror you downloaded Fedora from.

You should also be able to use the --check or -c option to check a list of md5sums from a file.

If they're not the same you have a problem; redownload the iso file.

Then you can burn the images with the burn CD image of your favorite CD burning software.

That link is good too. This is the way I describe it, and where people looking for Fedora support will find it. Plus mine's shorter. :p

I downloaded my Fedora using Bittorrent... what do I compare with?

The same MD5SUM list, it's the same files, just distributed differently.
