md5 check program for ReadyNAS Ultra

The "md5sum" command is pre-installed. In fact it is used for checking that firmware updates and add-ons are not corrupt before installing them.

You can SSH in and use. You can install the x86 EnableRootSSH add-on: http://www.readynas.com/?p=4203

However do pay heed to the warning:

With the EnableRootSSH add-on, you can now remote login to the ReadyNAS RAIDiator shell as a root user. Initial password for root will be the same as the current FrontView admin password. Please keep in mind that NETGEAR may deny support if you’ve enabled root access.

To be able to use SSH you need to install the x86 EnableRootSSH add-on (there are other addons to enable SSH access but these are for support use only).

On x86 installation is via the Add-ons menu.

Username is 'root' and password will initially be set to be the same as your admin password.

You can login using PuTTy on Windows.

Alternative you can use the Terminal (found at Applications > Utilities > Terminal on Mac OS X) on Mac OS X or Linux:

ssh root@ip.address.of.nas

Then use Linux shell commands.

If you wish to change the root password you can simply use the passwd command:

MDGM-NAS:~# passwd
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully

Thank you for your answer. ssh is already running on my NAS and I will try md5sum. Maybe I say "hello again", if I get problems running it ...

Simply use

# md5sum /path/to/file

So I tried this, and it makes me a sum of the md5-file 8)

ReadyNAS:/c/Data/Daten/Images/2008# md5sum 2008.md5
7907fa649f319a1f5e6d60096bae14ea  2008.md5
ReadyNAS:/c/Data/Daten/Images/2008# md5sum -?
md5sum: invalid option -- ?
BusyBox v1.18.4 (2011-03-28 19:08:01 PDT) multi-call binary.

Usage: md5sum [FILE]...
   or: md5sum -c [-sw] [FILE]

Print or check MD5 checksums

Options:
        -c      Check sums against given list
        -s      Don't output anything, status code shows success
        -w      Warn about improperly formatted checksum lines

ReadyNAS:/c/Data/Daten/Images/2008#

The I tried "md5sum -s -c 2008.md5" and get:

Here are the first lines of my md5-file:

How I have to use the programm correctly??

Do those thumbs files exist? e.g. /c/Data/Daten/Images/2008/directoryass/thumbs/2008.03.01 - 22.30.22.jpg

Yes, there is a folder called "thumbs". These are webalbums created with jalbum. There is a folder with the original images (images), a folder with html-stuff (res), one with the html-pages (slides) and one folder with the small thumb pictures.

But the directory ist not O.K. The path on the NAS is:

/c/Data/Daten/Images/2008/thumbs/2008.03.01 - 22.30.22.jpg

And the md5-file is located in the folder 2008. But in the output of md5sum it tells

/c/Data/Daten/Images/2008/directoryass/thumbs/2008.03.01 - 22.30.22.jpg

Don't ask me where the /directoryass/ comes from ...

You did a md5sum -s -c but the help info suggested doing a md5sum -c -s. It's possible that it needs to be done in this order for it to work properly.

It's also possible that md5sum doesn't like the * on each line of the list.

I think the command you should use to create a new md5-file with this change is something like

sed 's/\*//g' md5-file > new-md5-file

Or better yet, perhaps you could do a command to replace a space followed by an asterisk with just a space.

As your filenames include spaces you will also want to put quotes around them. You could use a command to replace just the first space in the line with a space + quotation mark (") and add another quotation mark to the end of each line. There should be commands to do these changes as well.
