Hi there, i also have some confusion when downloading the DVD full version of suse 10.
I am on suse 9.1 at the moment.
I went here to get the newer version: ftp://mirror.switch.ch/mirror/suse/suse/i386/10.0/iso/
and told my wget to download SUSE-10.0-DVD-SRC-GM.iso. It stops after 4.0 gig saying: "process for file protocol died"

I now have a file: SUSE-10.0-DVD-SRC-GM.iso.part which does not match the md5sum displayed in the textfile: md5sums on the ftp-server.
The strange thing is also that there is no md5sum for this file in the md5sums-textfile.
ftp://mirror.switch.ch/mirror/suse/s....0/iso/MD5SUMS
Instead of having SUSE-10.0-DVD-SRC-GM.iso it only has SUSE-10.0-DVD-SRC-RC4.iso.

My md5sum for my downloaded SUSE-10.0-DVD-SRC-GM.iso.part is:
9fdaff18e8075bb000c9435c5c9308f9
can i use this or can anyone confirm the md5sum? What am i doing wrong in wget?
Thanks!

The SRC-GM.ISO only contains the source packages and is not installable. You only need this if you plan to re-compile SUSE from scratch. If you don't plan to do this, stop wasting time and money and get the EvalDVD-i386.iso or the 5CD set.

back again
I downloaded, and burned SUSE-10.0-EvalDVD-i386-GM.iso with k3b which gave an error
with the output displaying the used growisofs command.
Is there any fast way to verify the written data, since it looks good? I tried md5sum but that doesn't let me act on a dir.

Don't use the directory, do it per ISO. On the DVD there is one file to md5, and on CD there are 5. Each ISO and its corresponding burned CD/DVD has an md5sum unique md5 to it.

Yes, that's what i want to do
I don't see the actual ISO on my dvd, i just see the individual files and dirs, so that doesn't compute.
I have the md5sum for the file on my disk which i now want to md5sum-check against my burned dvd.
What's the command to use when you want to display the md5sum for a whole dvd?
Is that still making sense ?

Well, depending on what you have installed, and which OS you are using a download platform, that depends. I use a little tool from Nero on Windows, and I have seen many little tools in Linux. Including a built in md5sum command. Mind you, booting it up and letting it check will work(but could waste a DVD). Since you already burned it, during the install one of the first steps is a media check, so you could use that, which will test the DVD for you.

The command which should be built in in linux:
Code:
md5sum "Archivname.ext"
So in your case, I would think:
Code:
md5sum SUSE-10.0-EvalDVD-i386-GM.iso
would be what you need to use.

I am on suse 9.1 now. Thanks for your suggestions & I know that i can 'verify' my burned dvd by just running it.
I was just wondering what the proper way would be to check the md5 for a DVD.
With your command i can check the iso which is on my harddisk
Code:
user@suse:/suse10>md5sum SUSE-10.0-EvalDVD-i386-GM.iso
320976f73076eb96b3c9226c9ae0cb70  SUSE-10.0-EvalDVD-i386-GM.iso
But nowhere can i find or view the 'iso' which i've burnt to dvd.
So which command can i use to md5 the whole dvd (as being an iso)?

There is a function in k3b to verify the just burned data. I think what it does is to create another iso from your DVD and compares the md5sum before and after burning. But I am not sure about this.

@abisko00: yes, k3b indeed tried to check it but i think it failed because it gave an error. Now i don't see any options in k3b to recheck it.

I think a way of checking the burnt dvd md5sum, is to make an iso out of it by (or mkisofs):
Code:
dd if=/dev/hdd of=cd.iso
and than checking that file with md5sum against the textfile with the md5-sums in it from the ftp-server where i got the file from.
I will try this once i can free up some harddisk-space.

But i cannot believe that this would be *the* way of checking my burned media.
Any other suggestions are welcome

You could try
Code:
md5sum /dev/dvd
or /dev/media however yours is set up.

Than you have a burning issue, it would seem.

You could try another piece of software like xroast, is I think the name.

i finally got the right md5checksum of my burned suse-dvd and found the solution over here:
http://lists.samba.org/archive/linux...ly/014002.html

Quote:
I suspect you'll find that it'll be reading trailing zeros/nuls/rubbish
at the end, which changes the MD5 hash.

There might be a prettier way, but try:
* finding the size of the ISO in bytes
* dd if=/dev/hdc | head --bytes=<size> | md5sum
so for my SUSE-10.0-EvalDVD (burned to dvd):
first check the size of the file with ls.
Than use that size in the command for dd:
Code:
user@suse:~> dd if=/dev/dvd | head --bytes=3621957632 | md5sum
7074137+0 records in
7074136+0 records out
320976f73076eb96b3c9226c9ae0cb70  -
That was the original md5sum i also got when i downloaded the file so succes!
Thanks for the help!
