Linuxhelp _ Technical Support _ Users cannot access folder, only root

Posted by: NiceLittleRabbit May 31 2012, 12:41 AM


I have been having a very strange (for me) issue with my Debian server.

There is a folder (Data), located onto another hard drive, with what seem correct rights to me, which only allows access to root.

Here come some screenshots:

First, just doing "ls" from "/"

debian:/home3# ls -l
total 256
drwxr-x--- 120 john family   4096 May 31 07:15 Family
lrwxrwxrwx   1 john Data       6 Mar 29  2011 Data -> /Data
drwxr-xr-x  30 john humor 237568 May 30 17:30 Humor
drwx------   2 root  root     4096 Dec  5  2009 lost+found
drwxr-x--- 153 john docs   12288 May 24 18:05 docs

Then, entering into Data as root:

debian:/home3/Data# ls -l
total 20
drwxr-x--- 4 john Data  4096 Nov 11  2010 Data
drwxr-x--- 2 root  root  16384 Mar  1  2011 lost+found

Then, Entering again into Data:

debian:/home3/Data/Data# ls -l
total 8
drwxr-x--- 9 john Data 4096 Apr 24 20:31 Data
drwxr-x--- 2 root  root  4096 May 21  2010 lost+found

And then, if I enter into Data again all my data shows up.

The problem starts at the first level "/".

Here comes a screenshot when I try to enter /Data as a normal user:

john@debian:/$ cd Data/
bash: cd: Data/: Permission denied

I know the path is weird, that's something that happened during a restore of the server and I have never understood why that was so, but it used to work anyways and I did not have time to dig into it. However, now no user can enter the /Data folder and it is more worrying.

Does anyone have any idea why that may be so?

Thank you in advance

It looks like your first ls command was run in the /home3 directory rather than in /

So, there is a link called /home3/Data which points at /Data. The permissions on the link are open, but the actual directory does not have required execute permissions to allow regular users to navigate to it.

As a first step, you can try:
chmod a+x /Data

Depending on how many levels of data directories there are, you may also need:
chmod a+x /Data/Data
chmod a+x /Data/Data/Data
