Hi list, - and a HAPPY NEW YEAR TO ALL! - I'm puzzled by md5sums. I've downloaded openSuSE11 (both 32 and 64 bit versions) and openSuSE11.1 (32/64 too). - I get the same odd errors with 11 as with 11.1. This is my situation: I try to verify the md5sum of openSuSE11(i386/32), it should be ed6a5b3feb668866df812b1c2aed9d7f openSUSE-11.0-DVD-i386.iso but using "md5sum openSUSE-11.0-DVD-i386.iso", I get: a38623810009842eeb1542a2052cfc2d openSUSE-11.0-DVD-i386.iso This, of course, is wrong. If I do a "md5sum -c openSUSE-11.0-DVD-i386.iso", I get 500+ lines saying the this or that -rpm file could not be read, general i/o error or so" Now if I burn an ISO DVD, it verifies correctly when doing the "check media" before installation (!). Installation starts fine, but in some cases breaks later on, but not always... I use K3B for burning, it reports a sound md5sum. I downloaded the isos from mirrors and directly from SuSE too. I downloaded from two different locations, albeit to the same PC (my laptop). I stored the received files (during download) onto the harddisk and also onto a USB stick. Same story. As you can tell, I've done quite a few downloads...All the downloaded files yield the same md5sum (using md5sum without the -c flag), never mind what media I store onto. And regardless of wherefrom and my method of downloading. As of now, I'm not really able to install openSuSE11(1) to anything, as I can't seem to get this right.

Hi list,

- and a HAPPY NEW YEAR TO ALL!

- I'm puzzled by md5sums. I've downloaded openSuSE11 (both 32 and 64 bit versions) and openSuSE11.1 (32/64 too).

- I get the same odd errors with 11 as with 11.1. This is my situation:

I try to verify the md5sum of openSuSE11(i386/32), it should be

ed6a5b3feb668866df812b1c2aed9d7f openSUSE-11.0-DVD-i386.iso

but using "md5sum openSUSE-11.0-DVD-i386.iso", I get:

a38623810009842eeb1542a2052cfc2d openSUSE-11.0-DVD-i386.iso

This, of course, is wrong. If I do a

"md5sum -c openSUSE-11.0-DVD-i386.iso", I get 500+ lines saying the this or that -rpm file could not be read, general i/o error or so"

Now if I burn an ISO DVD, it verifies correctly when doing the "check media" before installation (!). Installation starts fine, but in some cases breaks later on, but not always... I use K3B for burning, it reports a sound md5sum.

I downloaded the isos from mirrors and directly from SuSE too. I downloaded from two different locations, albeit to the same PC (my laptop). I stored the received files (during download) onto the harddisk and also onto a USB stick.

Same story. As you can tell, I've done quite a few downloads...All the downloaded files yield the same md5sum (using md5sum without the -c flag), never mind what media I store onto. And regardless of wherefrom and my method of downloading.

As of now, I'm not really able to install openSuSE11(1) to anything, as I can't seem to get this right.

Questions:

a) The md5sums listed on the openSuSE web are (of course) correct

b) what's the correct and proper way of verifying the md5sums?

c) I used wget, firefox directly and a FF-extension called DownThenAll for downloading. What would be your recommendation?

And as always, thank you!

-- ------------------------------ Med venlig hilsen/Best regards Verner Kjærsgaard

a) of course b) just let k3b do it automatically (when it reads-in an ISO) and visually compare it with a) c) all your methods are correct. If you want additional error-checking, you can use ktorrent with the torrent links; then, when ktorrent downloads the ISO, you right-click on the ISO and select "Check data" from the pop-up menu. d) I'm suspecting your CD/DVD writer may be oldish or a bit incompatible, or maybe the media are not overly compatible with your particular optical drive. In addition, check all k3b settings and verify they're all set to defaults. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Well, it reports that it burned correctly the image you gave it, which we know is bad.

Just don't get too enthused :-) . Following comment is not directed at aria2c nor at k3's ability to burn a DVD and then verify it as being "successful". Burning DVDs under k3 works fine. Using k3 you will find - I do, and have been doing so for some months - that if you burn a *CD* and have the verify function set then every time the verification process will show that there is an error in the copy compared to the original -- however, there is NO error, but k3 always reports that there is an error. (BTW, just on this point of the verification process reporting an error in the copy: what a total waste of time that k3 has to ALWAYS check though the *whole* CD or DVD (upt o 8GB big) to report an error even though the error may have occurred at some point at the beginning of the CD or DVD. Why not report and stop further checking when the error is first detected?)

Yes, I think I have seen this behaviour.

Because they don't do a byte by byte compare, but a calculation of a checksum. The checksum algorithm requires read the entire data stream. The byte compare needs reading two streams simultaneously, an average of half way: thus the same total data flow, at a slower pace, probably. They could have both algorithms and let the user choose. I usually burn by command line, my own script, and byte compare the result. I can use k3b to generate the iso image. - -- Cheers, Carlos E.

Yes, but have you submitted a bug report about it, have you, have you, eh? :-) :-) .

OK, good point.

As you know, the available option at the moment is to either to Verify or not to Verify -- I think this is fine. However, what the Verify could do ( as an answer to the byte-by-byte check) is to do a sector to sector verification, and repeat this verification should an error be found, and then stop when an error is confirmed.

I usually burn by command line, my own script, and byte compare the result. I can use k3b to generate the iso image.

It is great to see these satisfying results. Carlos, thank you very much for spreading the word. I surely hope that this will be used much more in the future!
