DSM-G600, DNS-3xx and NSA-220 Hack Forum

I think with Samba (which the DNS323 is running) you have two sets of permissions, the permissions to connect to the share (which you have set in the Web UI to let everyone in), and then the permissions of the files on the disk.

Maybe something has changed the permissions of the files on the disk?

Can you telnet to one of the foders with files that you are trying to access and do

ls -l?

Then do

cd .. 
ls -l

If "everyone" doesn't have permission to get in to the folder and read the files then it doesn't matter what the admin UI says, you still won't get your files.

If that is the problem, then you can use chmod to make all files publically accessible.

Check your firewall - especially if you're using something that does automatic updates

First, what is the firmware version on your DNS-323?
Second, do you have fun_plug installed?

You seem to think the problem lies in the DNS-323, so we can check the configuration
of the Samba software running on the DNS-323.   The Samba software provides file and
print services for various Microsoft Windows clients, but will need telnet enabled to
access the command line interface of the DNS-323.

Once we determine that Samba is setup correctly, we can look at your windows networking,
if you still can't connect, to see if the problem lies there.

O.K., lets start by confirming that Samba is running

The 'ps' command shows the processes running on a Linux system,

So, telnet to your DNS-323 and run the following command and post the results.

# / ps | grep smb

Next, we'll need to see the contents of your Samba configuration file, smb.conf.
Post the output of this file.

# / cat /etc/samba/smb.conf

How Linux savvy are you?  Are these instructions too simplistic?
Also, have you made any customizations to the smb.conf file?

O.K. it looks like Samba IS running and your smb.conf looks fine.

A couple more things to check to see if name resolution is working...
run the following command on the DNS-323 and post the output

# / hostname

# /ifconfig -a

On a winXP box run the following command in a command prompt window
and post the output

c:\>ipconfig /all

c:\>nbtstat -c

For, the next two command, replace <dns-323-hostname> with the output of the
hostname command from your DNS-323 (from the smb.conf file this is probably "DNS-323")

c:\>ping <dns-323-hostname>

c:\>nbtstat -a <dns-323-hostname>

Another question, is the DNS-323 using a static or dynamic IP address assignment?

Permissions for Data look odd to me (rwx-w--w-) ?

That is the folder I am trying to map to. On the other hand, when I try mapping the drive root (Volume_1) I have the same problem. Is Volume_1 a symlink (or such) for HD_a2 btw?

Yay!

There are a few people on the forum who have had to do that - search for chmod 777.

I don't know why they broke - did the files get created by one user, and then you changed the access to "Everybody"?

Or did you install some other software that might have affected this?

vedeja wrote:

No, the name of the share (how Samba presents your folder to the windows network)
is defined at the bottom of the smb.conf file

[ Volume_1 ]
comment =
path = /mnt/HD_a2
valid users =
read only = no
guest ok = yes
oplocks = yes
map archive = yes

these options mean the actual filesystem directory /mnt/HD_a2 (in the path option)
will be shared as Volume_1 (in the brackets)
and the other options lines will be in effect for this share

vedeja,  The Data subdirectory was created by user "nobody" and
group "501" wonder what user/group you are connecting as curently?

To further understand which user/group you are now accessing your
DNS-323 as, you could create a new (temporary) file in the data directory
through the window XP share, then telnet to the  DNS-323 and
ls -l the /mnt/HD_a2/Data directory  to view the user and group.

In Linux filesystems the user and groups are numbers,
there are files that translate the numbers to human readable
names.  These file are /etc/passwd and /etc/group

if you type # / ls -nl /mnt/HD_a2/Data you will see the
numeric user and group ids for the files.

There is a user name "nobody" in /etc/passwd, it is a generic low
privileged user and probably belongs to the group id
501, however there is no entry for 501 in the /etc/group
file, so the listing just shows the numeric.

You are probably connecting to the DNS-323 as nobody because
you allowed guest users (in the smb.conf file) and you are not
authenticating from your windows box.  Perhaps you don't have
a user or password setup on your windows box?

But you have a fun_plug script installed, so you can still telnet in is that right?

So what do you see if you type
ls -l /mnt

What about
ls -l /mnt/HD_a4
