Hi Charles, OK the gpg key and the MD5SUM file, do I download these from the RH site, or do they already come on my RH 8 distribution disks? WHere on disk or site would they be located? Or is the MD5SUM file the actual file that I am testing against the distribution disks? I read at http://userpages.umbc.edu/~mabzug1/cs/md5/md5.html that MD5 is a more reliable way to test data integrity, if I do MD5 checks is a checksum test redundant? >Depends on how you want to do it. First, import Red Hat's gpg key >(preferred), or add the appropriate command line switch to the rpm >call below to disable gpg key checking.
