Description Oliver Mahmoudi 2008-06-24 12:30:01 UTC 
 Dear FreeBSD Team,
 
 I'm writing you because I'd like to ask you if you could give me some advice for the 
 following problem:
 
 Lately I've done quite a lot of reading on the FreeBSD OS and I decided to install 
 the latest release on my system. So I went and downloaded the ISO images for the 
 i386 CPU from the following link:
 
 ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.0/
 
 Upon having downloaded the first two images i.e. "7.0-Release-i386-disc1.iso" and 
 "7.0-Release-i386-disc2.iso", I generated their MD5 checksums and realized that they 
 do not agree with the ones published on the above website. I have tried different 
 MD5 generators. I have also downloaded the files from different mirrors such as 
 "torrents" but I always found that the checksum was another. 
 
 Also, the sizes of the files that I download are different. E.g. the size of the file
 indicated for disc 1 in the download links is 509MB. The disc 1 files that I downloaded 
 however, had sizes ranging from 210MB to 230MB.
 
 Now what do I do?
 I am eager to install FreeBSD7.0 on my computer, but that checksum matter won't let
 me sleep.
 It would be nice if you could give me a hand on this one.
 
 Thank you in advance.
 
 Regards,
 
 Oliver

To submitter:  The size of the disc 1 ISO image is exactly 534177792 
bytes.  If you are seeing sizes any different to that then the download 
is being corrupted somehow and the checksum will be wrong. 

With FTP, if the transfer is somehow interrupted then you will end up 
with a shorter, corrupt file.  You could try downloading from another 
mirror closer to yourself (assuming you are in Germany), you could try 
ftp://ftp.de.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.0/ 
which I've just downloaded the disc1 ISO and verified the checksum myself. 
Another thing to check is that you are downloading the ISO in BINARY more 
and not ASCII - the Windows ftp client at least defaults to ASCII mode 
which will corrupt the image. 

I am quite surprised you are seeing this with the torrents, however, as 
torrents are checksummed in such a way that your torrent downloader should 
not say the download is complete until every part of it is correct.  It 
may well be worth deleting whatever is downloaded and trying to download 
the torrent again, possibly with different torrent software. 

If you are still having problems, let me know what software you are using 
and I'll test it at this end.  If you do successfully manage to download 
the image, let me know and I'll close this PR. 

Lastly, for problems like this, you are probably better off asking on one 
of the FreeBSD mailing lists, like freebsd-questions@FreeBSD.org - the PR 
database is really for reporting bugs in FreeBSD itself, and not general 
questions.

Close, submitter has now successfully obtained a copy of the ISO.
