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

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 URLs.

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!

Subject: [libreoffice-users] Use of MD5 and other HASH values of LibO package downloads and 
alternate distribution DVD uploads


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 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 

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 

"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:  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:

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).


p.s. I've cc'd this to the QA list to see if there are any other recommendations for the process.

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.
