As a newbie I am a bit unsure of checking the iso download before burning to DVD.
Before you burn your CD/DVD images, you should check the files for errors. Two files named *.iso.md5 and *.iso.sha1 are available. These files contains hashes for each ISO image that is available from that download location. The relevant line would look like the following:
To be sure that download did not contain any errors, you should create this number using MS5 or SHA1 algorithm for your own ISO image.
On Linux, run one of the command,:
If there is any difference between the output of the checksum command and the above number, the download is broken and should be repeated.’
Is some a linux command?
I assume it is run at the same location as the download?
If you use openSUSE 11.1 (i didn’t notice your signature, almost blind am i )
then you can simply check the file with aria2c (available for 11.1 and 11.2). Just find the metalink for openSUSE 11.2 and start downloading with it (works from console but is simple as:
aria2c <torrent or metalink file>
It also works with normal http files
Aria automatically ensures that the file is downloaded fine(like a torrent client i guess except http downloads but i never had problems with those either).
So if you already have the downloaded iso and it is wrong then just start downloading a new one with aria2c BUT substitute the file that is being downloaded )after stopping aria2c with Ctrl+C with the one you already downloaded (copy not cut, to be safe).

this looks incorrect - what is the best method of correcting. My download speed is quite low and took 8 hours.
