Hello,
I just downloaded the very great CentOS LiveCD and have some issue with the sum.
when I do md5sum -c md5sum.livecd they simply don't match.
But when check the size file with the file size posted by johnny in the announce http://lists.centos.org/pipermail/centos-announce/2006-May/012905.html They both match (in 717729792 bytes)
Probably I am doing something wrong, just to be sure before burn it.
I used the url: http://styx.biochem.wfubmc.edu/mirror/CentOS/4.3/isos/i386/
Regards, --alain
This just means that your download most likely got very slightly corrupted somewhere during download - it might be a single lit bit which flipped, or it might be major.
The best solution would be to resume the download via bittorrent or via rsync to redownload only the part (most likely way < 1%) which differs. If you can't use the above (not sure if there is a torrent for it...) then you'll have to delete and redownload -- or burn anyway and hope for the best :)
As for rsync - I'd suggest finding an rsync capable server (mirror2.kernel.org comes to mind, not sure if it carries the liveCD) and trying rsyncing from it... (read up on man rsync, although it's not light reading).
As a starting point the following will likely work (one line) - remember to include the proper path to the destination file (last parameter) or to have it in the current dir:
rsync -vv --stats -rlptDHSzP --delete "rsync://mirrors2.kernel.org/centos/4.3/isos/i386/CentOS-4.3-i386-LiveCD.iso" "CentOS-4.3-LiveCD.iso"
(not all the options are needed but I'm riping of my own script which does site wide mirroring)
Cheers, MaZe.

Ahh, the connection is treating me bad, I've been trying like 3 times with a crontab-wget line. Think, there most be another waiting crontab night :-).

I have no access to bittorrent here :-\ .

well, think this will be my another crontab-wget waiting night ;-)

Thanks Maciej, appreciate a lot that clean suggestions. I heavily tried to do an rsync, some time ago, to mirror a repository and keep some local updated packages here for the local servers and some workstations but just errors appeared to me when I tried to do so, all seem to me like have no read enough about it or that a top level firewall (which I've no control of) in the intranet is blockin it. I am studying firewalls now to have more arguments about this issue and be able to use the wonderful-necessary rsync tool, that I think should study a little more.
By now, I will delete and redownload the entire file using my friendly wget again (hoping the best) and will write you back the results.
Cheers, MaZe.

Now it is right, the sum match correctly.
Thanks MaZe, as you said just a bit download problem.
