I just downloaded the DVD mentioned in the Subject. I want to verify
the download is good but have not found a location on the North
American website to get the checksums.
K3B says there is an MD5 checksum of:
96560a0b6c117a07d32d33baa1e2ef30
Is this correct?
Shouldn't the checksums be available on the website.
i already use LibreOffice on My Linux base system. See Signature.
I now want to put it on my wife's Win 7 system.
Thanks.

Hi 
Don't worry about checking it. The best way to know is to burn the dvd and then see if it works 
The NA team doesn't know how to generate the checksums. They keep asking how to generate them but no-one helps them. I don't know either, just in case you wondered.
If you could point them to some documentation or help them learn how to generate md5sums or Sha or whatever then that would be a huge help.
Apols and regards from

I do not have any software to create a checksum. But, it is downloaded from the LO servers, so they have them for you.
On the green button for the downloading of the ISO files, there is an "Info" text. You click on that text and you should get a page showing mirrors for the files and their checksums.
I would not download the 3.5.6 version. IT has a "bug" in the download page that involves the Windows files. I did not upload the modified version, since it was too close to the 3.5.7 release and having the 3.5.6 version uploaded [take 9-10 hours on my part to upload a full DVD ISO file] and then in a week or so the 3.5.7 DVD will be listed as the current version. It seemed not doable to just upload the 3.5.6 version "fix" when 3.5.7 was so close. Actually I just found the "bug" about a week ago, a few days before 3.5.7 was released to the public.
As soon as I downloaded all of the 90+ 3.5.7 needed install files , I created the 3.5.7 DVD ISO file and uploaded it to the "holding server" to wait till the conference was over so the person would have it available to do the move to the download server[s]. Then it was up to the mirrors to get the new folder[s]/file[s] sync-ed up and then the new ISO file will be available to the public for downloading.
In a few days the 3.5.7 DVD will be on the LO servers. With the conference going on, the person who moves the ISO file to the proper server and folder was not available to do the move.
But it will happen in a few days, hopefully. The exact date is not known.

This should be the direct link to the 3.5.7 DVD download page.
AS FOR
downloading the Windows version for your wife's computer, just use LO's download page. It will be quicker. If you want to install the 3.5.6 version, you will find it here
http://www.libreoffice.org/download-more/
or here

Where are you seeing that "Info" text? I certainly don't see it.
As for checksum, the usual one to use is called md5sum. The utility for that comes with Linux and is also available for download for Windows. Disc burner software will also check md5sum. You should always have md5sum available for downloads, not just CD/DVD images. I have often downloaded multiple files from a site and there will usually be a file called md5sum, which contains md5sum for all the relevant files. I can then download that to the same directory as the other files. Then, in a command prompt, I enter the command md5sum -c md5sum, which then runs md5sum on all the files listed in that md5sum file and displays the results as to valid, bad or missing. However, even just displaying the md5sum on the web page makes it easy to verify a good download, by comparing the locally generated md5sum with what's displayed on the web site.
Hi
That does sound hugely useful but please could you let us know the name of the utility you used? If it was for a particular DE i'm sure we could work out the name for another DE if we need to. Just knowing the name of 1 would help!
Also any suggestions on how to use the utility? If it's command-line only i think it's still possible even for us point&click users but we could use a little guidance. Errr, i'm still not in the NA Dvd team but am still interested in how to generate an Md5sum.
Many thanks and regards from

In Linux, it's called "md5sum". As for Windows, Google on "Windows md5sum" to find utilities you can download.
Here's a list of the directory where I downloaded openSUSE:
jknott@linux:~/download/suse/12_2 $ ls -l
total 8903692
-rw-r--r-- 1 jknott users 126 Sep 16 14:41 md5sum
-rw-r--r-- 1 jknott users 4448059392 Sep 16 14:24 openSUSE-12.2-DVD-i586.iso
-rw-r--r-- 1 jknott users 4669308928 Sep 16 14:22 openSUSE-12.2-DVD-x86_64.iso
The md5sum file contains:
26dd6c187f743f3af0cbb31eed138a07 openSUSE-12.2-DVD-x86_64.iso
0373980cd6f270e1172067b86c044633 openSUSE-12.2-DVD-i586.iso
If I run the command md5sum -c md5sum, I get:
openSUSE-12.2-DVD-x86_64.iso: OK
openSUSE-12.2-DVD-i586.iso: OK
This shows both files match their md5sum.
If I run the command md5sum openSUSE-12.2-DVD-x86_64.iso, I get:
26dd6c187f743f3af0cbb31eed138a07 openSUSE-12.2-DVD-x86_64.iso
This matches the value from the web site, and shows the file is OK.
The thing about md5sums is that a small change in the file results in a large change in the file's md5sum. This means that you don't have to check every character. If a few at each end are correct, then in all probability the file is OK.
As I mentioned, disc burner software will generally display the md5sum of a file before you burn the disc. Just check that against the md5sum from the web site. There may be graphical utilities available, but I haven't had the need to use them as the command line utility is so easy to use.
Hi
Wow!! Thanks :) That sounds reasonably easy and "do-able". I have to pop out but hopefully Tim can let us know how it's gone if he gets time to try it out.
many thanks and regards from

NO ONE
has given me the answer before on how to create a md5sum file before. And I asked that question back in the 3.3.x version days.
I have printed your answer out to PDF and I will place it on my folder[s] for the NA-DVD work.
I use Ubuntu 12.04/MATE [10.04/GNOME before this month] to create the NA-DVD web site and the ISO file.
I use Kompozer and Kate for most of the HTML work.
I use K3b to create the ISO file
I use Filezilla as my FTP client.
K3b creates a checksum but I do not know where it is "stored" for my use.

You can store it in a file "md5sum" with the command md5sum [filename] > md5sum.
As I mentioned, it can be used for any file, not just ISOs.
If you're saving the md5sum for multiple files, use the above command for the 1st and then md5sum [filename] >> md5sum which concatenates the additional md5sums onto the existing file, rather than create a new file.
Recently I saw some article about HashTab. Being Linux user myself, I have not
tried it. But it looks quite nice.
Unfortunately, it is not open source program and they provide "commercial"
license. I don't know if Kracked Press webmaster's scenario would require such
license or not.
Anyway, you can download this app from
<http://www.implbits.com/HashTab.aspx>.
Hi
I think Tim uses a dual-boot on his main machine so the linux option is fine.
Errr, did someone say they managed to generate an Md5 of the iso on the website and compared it to one generated from their download? If so does that mean the one they generated could just be written onto the website? Sorry, i am being really slow on the uptake here!
Presumably it would be good if Tim could generate one based on the version he has on his machine and check that it matches the one built for the website? Would that be a good way of confirming that whatever is on the website is completely correct?
Thanks and regards from
Tom

You'd get the md5sum from the web site and compare with the downloaded file md5sum. The only one writing to the web site should be the one who placed the files there. Please note that md5sum verifies only the integrity of the downloaded file. If it came from a web site after it had been tampered with and the md5sum recreated, then you could still get something nasty. So, it's best to check against the original source md5sum. There may be authorized mirrors of the original site that can also be trusted.
My desktop is not dual boot, but I have a laptop that is.
desktop - Ubuntu 12.04/MATE
laptop - Vista 32-bit [came with] and Ubuntu 12.04/Mate "testing system".
My NA-DVD ISO file is placed on the LO server system, and the mirror sync system. Soon 3.5.7 will be there.
I never did use any md5sum system because I never knew how to use them properly or create them properly.
My NA-DVD has about 90 LO install files plus the language and help packs. That is a lot of md5sum files to generate for the online version every time the install files are changed, either LO's file or all of the other files that are available. My current 3.5.x folder has 866 files and folders in that folder system. The actual number of installs, language/help packs, documentation, dictionaries, templates and extensions, artwork and images, and extra software, that are on the DVD is currently not known - since I never really kept a count of them. Which file need a md5sum and which do not?
I created the NA-DVD so people could download a copy and burn it to their own DVD, then they will have a physical media to give to people with dial-up or ones who could use all of the documentation, dictionaries, etc., on one disk for easy access.
The people at LO are hosting the ISO files, thank you, since my hosting company will not allow a CD or DVD sized file to be placed on their servers. They do not want to have their system used as a repository site. I can have all of the files in the DVD online as a web site, but not them combined into an ISO file. I also have unlimited bandwidth/traffic for the site. That would make a repository site creator happy, but sorry no repository allowed there. If I could I would have been one of those authorized mirrors are well, but sadly not allowed either.
I have created a page listing free software - for Windows - but to stop any possible "nasties" that could happen, I link back to the software's original download pages. Also, I do not need to keep up with their updates/upgrades. To be honest, since I went to Ubuntu for my desktop, since I could not afford to buy Win7 and get the desktop I wanted, I have not kept up with looking for good free software alternatives for Windows users. When I was a Windows user, I needed a place to go to for all of the software I use or have used so I, or friends, could easily find the software I/they might need. I still point it out to people for a place to find links to free anti-virus and firewall software. http://lungstrom.com/list/
Tim,
We applaud the work you've been doing on the English-NA-DVD, but since you've taken on that responsibility its "cradle to grave" handling also requires that you validate receipt of the initial ISO image upload to the Document Foundation Mirrors.
TDF will take your upload of bundled components and post it exactly as they receive it. Followed by TDF implemented MirrorBrain metadata service that calculates the initial HASH values (MD5, SHA-1, SHA-256 and BitTorrent) and publishes the details for use on the download mirrors.
Point is, they won't normally test that they have a good upload from your build system--that responsibility is yours. And to add to your effort, to be technically correct you should probably verify the HASH value of each component installer you download for use in the compilation--found most conveniently at the http://download.documentfoundation.org/libreoffice/ where you probably want the stable/ tree (and can check on your box/ DVD distro). Navigate down into the build you are compiling and the OS. On the page listing the language specific installers each file will have a corresponding MirriorBrain provisioned link labeled "Details" that has full metadata of just that file including the HASH values. Check each package you will bundle against those values so you know you have a clean download. You probably don't want to be responsible for distributing a corrupt install package that was incompletely downloaded as you build the DVD.
Then, once compiled into your English-NA-DVD .iso image, you need to calculate a HASH value of the ISO being uploaded. You need this to compare what you send against what the transfer server receives.
After upload, or probably once published to the TDF mirror, compare the HASH value(s) the MirrorBrain published metadata. When uploading or downloading I generally will calculate and compare against the first few digits of MD5 and SHA256 HASH values
As an example, since you are on a Linux, you have the terminal window command line use of these commands:
"md5sum LO-3.5.6_English-NA-DVD_all-platforms_multi-lang_plus-extras_v2.iso"
"sha1sum LO-3.5.6_English-NA-DVD_all-platforms_multi-lang_plus-extras_v2.iso"
"sha256sum LO-3.5.6_English-NA-DVD_all-platforms_multi-lang_plus-extras_v2.iso"
Folks on Windows don't have a Microsoft provided digest tool--command line or GUI. But there are many to be found. Because of the range of digest HASH types I have to deal with I prefer a digest tool integrated with the Windows shell and widely use the "freeware" Hash & CRC tool published in the fileTweak utilizes of Febooti. Available here: http://www.febooti.com/downloads/ Installed as administrator, it then gives ALL users the ability to calculate HASH values from the Properties panel (i.e. <right mouse>) of any file viewable in Windows explorer shell GUI.
If you'd like to compare for real, here are the HASH values for the last ISO build you posted as available at:
LO-3.5.6_English-NA-DVD_all-platforms_multi-lang_plus-extras_v2.iso

Hope that is clear enough so that it helps you to understand that there is a bit more work you need to take on to assure the quality of your DVD box/ (i.e. as in Boxed set software distribution).
Stuart
p.s. I've cc'd this to the QA list to see if there are any other recommendations for the process.
Hi
The workflow for the NA DVD Project involves
1. downloading the installer files from the LO or TDF servers
2. bundling it with some documentation, Extensions and 3rd party programs
3. re-uploading the resulting .iso through a domestic line that takes somewhere between 4-8hours (assuming it goes smoothly and the line doesn't drop-out).
The 'broadband' line is in a building that is of an age that prohibits upgrading the line. A few people looked into 3rd party Cloud space to store and work on the files but the options seemed inflexible and quite expensive. The amount of space required only occasionally tips over the amount the team could get for free without using fairly dubious 3rd party space. A lot of the space is for files that already exist on TDF and LO servers.
Also the team wasn't completely confident about how much to trust or how to use any strange tools available on 3rd party Cloud-space. There must be some easier way of doing this without having to learn tons of advanced new stuff!

Tom
My 4.2 - 4.3 GB of an ISO file takes about 9 to 10 hours to upload.
Also, I do not have access to the mirror system of servers. I upload it to a different server where it is them moved onto the system that it part of the mirror sync system. [or so I have been told] So I cannot use the TDF system to verify my uploaded file. I do not have that option[s].
I upload to the server I have access to via Filezilla.
Personally, I really do not want to have the permissions to access the LO folder system that is part of the system that will be mirrored. I do not want to have a partially uploaded file get mirrored when the "local mirror" goes and syncs to the master files/folders on the LO server[s]. It is much safer to upload it to an "outside" server folder "outside to the mirrored folders", and then have a server support person move it from the temporary folder to the one it needs to go to. For the 3.5.7 DVD it would be the folder that holds the files for the
http://www.libreoffice.org/download/?type=box&version=3.5.7
page, where-ever it is located.
For a different ISO file, the link is:
but that does not mean that it is the exact folder of "/libreoffice/box/3.5.6/" off the "download."sub-domain folder but something that the system associates with it.
I know my hosting system has a lot of "relative" file/folder placements in my domain.us/folders/folders/file.html URLs.
Tim,
Very reasonable that you would not have, or want, direct write access to the pool holding the master copies for distribution out to the mirrors--that is syssamdin magic better handled by the folks running the mirror service.
My suggestion is that you verify that the MirrorBrain HASH values for the .ISO file against what you created locally prior to you upload. That way you can be certain that what you prepared will make it intact out to the mirrors. Each user then must be responsible for verifying their own downloads, with some trust that what is being downloaded is your original. Using the HASH values facilitates that at all steps--but you set the foundation for it.
You can wait for it to post up to the mirrors and grab the MirrorBrain HASH (as either the Info, or Details link--same content), or you can ask your contact to provide you the HASH value of what they received at the transfer server. Or if you're conservative, just do both.
Practice a bit with the md5sum, md256sum and you'll soon make it habit for all your data transfers--even locally between your computers.
Stuart
here is the results of the md5sum command for the ISO file I uploaded to the server admin.

shows the same MD5 HASH calculation you obtain before upload. You can now be comfortable the TDF mirrors are distributing exactly what you posted. And of course if they were not, you'd need to correct with another upload attempt until it is received correctly.
