Hi Folks,
I am currently running fedora2 and am interested in downloading and upgrading to fedora4. I downloaded the following
FC4-i386-disc1.iso
FC4-i386-disc2.iso
FC4-i386-disc3.iso
FC4-i386-disc4.iso SHA1SUM
FC4-i386-rescuecd.iso

The sha1sum values do not match those on the fedora website or the file
they are

bd27e7699a16b731334eb6ccdccb78df679d577a FC4-i386-disc1.iso
3e03335d5ef0627e00e9890113361fa018cb18ea FC4-i386-disc2.iso
d32832c7491edae87cc4f4efb91f8702eccc6522 FC4-i386-disc3.iso
3d475a534e160864a9e4e5fa3f10936d428f10d2 FC4-i386-disc4.iso

while the file and website say I should have
FC4-i386-disc1.iso (sha1sum: 3fb2924c8fb8098dbc8260f69824e9c437d28c68)
FC4-i386-disc2.iso (sha1sum: 31fdc2d7a1f1709aa02c9ea5854015645bd69504)
FC4-i386-disc3.iso (sha1sum: 032455cdf457179916be3a739ca16add75b768b7)
FC4-i386-disc4.iso (sha1sum: f560f26a32820143e8286afb188f7c36d905a735)

Does anyone have any idea why this might be different?

Thanks very much.

They may have been corrupted during download, if you weren't using a application like bittorrent or rsync (which perform application level block checking) to get the files. Not to worry, either command can check and correct the damaged files so you don't have to download them again. For example:

rsync -av --progress --partial rsync://srl.cs.jhu.edu/YUM/fedora-core/4/i386/iso/FC4-i386-disc1.iso ./

This will read the FC4-i386-disc1.iso in the current directory and correct it against the one at the specified site. There is a list of rsync servers on the Fedora mirror list here.

Macemoneta Thank you. This appears to work great. I guess I can download directly using this function and save a whole lot of time. Well time to read the man on this one I guess. Thanks again!!

Also does it matter from which mirror I am downlaoding an iso...What I am after is 100% assurance that the iso I downloaded from
http://download.fedora.redhat.com/pu...i386-disc2.iso
OR
http://mirrors.evrocom.net/fedora/li...i386-disc2.iso
are identical with no change in even a single bit wrt size.

It doesn't matter where you download the iso from. Just remember to download the sha1sum file from fedora.redhat.com. That way any tampering at the mirror will fail the check. If you get a failed sha1sum, use a different mirror to correct.
