What is the best way to obtain an exact copy download?--wrong md5 after downloading 5.3dsc1,2=(
Good day! After downloading disc1 and disc2 of freebsd 5.3, my boss told me to verify the download using md5. And to my surprise, none of those two iso's have the same md5 as that of the md5 written in CHECKSUM.md5. This is the first time I ever use the md5 and for so long, I didn't bother doing so with every huge download I make. But then the previous cd's works fine. My boss told me that if I continue to burn those ISO's, somewhere within the disc, there's a broken file and I'm gonna have a problem for sure. He also told me that there are a lot of factors behind this.. Question: On the middle of my download, how will I know if I'm still downloading the correct file, that no packet is being dropped and that I will end up in a perfect mirror file download? Do you know any downloading tool that will do just like this? Earlier, I just used the konqueror when I downloaded those ISO's. Is it really that hard to download? We're using E1 modems and our internet connection is quite fast. I'm just thinking, we are still lucky because of this. But how about those people with low bandwidth internet connection? Do they have a choice? How about the fetch(1) program? How accurate is it? Thanks. __ Do you Yahoo!? Check out the new Yahoo!

Some times, if you start downloading an ISO image while it is still being uploaded to the ftp-master server or while a mirror still fetches the same ISO image from ftp-master, what you get is an incomplete download. Try comparing the sizes of the files on the remote server after a while. If it has changed, the ISO iamge is still being uploaded to the FTP server; wait a bit and retry.

Do they have a choice? All this should be handled gracefully by the TCP network. AFAIK, there is no easy way to verify half of a file while it's still being downloaded over FTP. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Another option (if you do not want to re-download both CDs) is to have someone with known good copies help you recover the existing files. Two utilities which can do this are zidrav and quickpar. I doubt very much that more than 1MB of parity data would be required to repair these cd images; they are probably off by only a few bytes. -Aaron ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
