I would like a quick explanation on how to use the md5sum program to check the ISO downloads with.
The intructions on the redhat site state, "After downloading the ISO
images, check the MD5 checksums for the ISO images to ensure that your
download was successful. Do this by running the md5sum program from a
shell prompt against your ISO images and comparing the values returned
against the ones published by Red Hat."
How do I use the "shell prompt" to do this?
What I do is put the download and the md5sum file into the same directory.
then I cd into that directory and run
md5sum -c file.md5sum
where file.md5sum is the name of the file containing the md5sums.
Often the md5sum file will have more files in it then you downloaded - those will fail as missing, but the files that you have should pass with an OK mark. For iso's, it could take a little while to compute the sums.
[mpeters@devel heidelberg-binary-i386]$ ls -1 FC3-i386-disc1.iso FC3-i386-disc2.iso FC3-i386-disc3.iso FC3-i386-disc4.iso FC3-i386-DVD.iso FC3-i386-rescuecd.iso MD5SUM
That's listing the files - here is the check:
[mpeters@devel heidelberg-binary-i386]$ md5sum -c MD5SUM FC3-i386-DVD.iso: OK FC3-i386-disc1.iso: OK FC3-i386-disc2.iso: OK FC3-i386-disc3.iso: OK FC3-i386-disc4.iso: OK FC3-i386-rescuecd.iso: OK [mpeters@devel heidelberg-binary-i386]$
