That's not good, if I understand correctly. Are you re-downloading the file each time? Or is the same file staying untouched on your local filesystem? If it is the former, maybe you're having transfer wierdness (ASCII mode, stream error, aborted download, etc), and MD5 is just doing its job in telling you that something is wrong. If it is the latter, run some tests... maybe your HD or controller is flaky, or you've got something writing to that file, or evil gnomes are secretly replacing your ISO bits with the latest greatest N'Sync MP3s. Or maybe a GNU hacker has intercepted your transmission and is injecting malicious GPL'd binary code into the gzip on the fly. (I think the gnome theory makes the most sense, but all of these things would definitely result in different MD5 sums). - Ryan > Thanks, > > M. Callihan > > P.S.
