cant cd and even after the read permission is set.

ununun · 08-27-2011, 12:45 PM

hi everybody

i (usr1) am trying to read only share /home/usr1/music with usr2 and others.
so here what i did

Code:

[usr1@arch ~] chmod -R o+r music

Code:

[usr2@arch ~] ln -s /home/usr1/music music

but still usr2 cant cd

Code:

[usr2@arch ~] cd music
bash: cd: music: Permission denied

whats wrong here ?
is there any simpler solution ?
thanks in advance.

Check if the directory has the executable permission set. For directories the x permission means you can access them, otherwise you get the permission denied error.

My first guess is that maybe you messed up the symbolic link?

SUGGESTION:
Try to explicitly "cd /home/usr1/music" and see if that works (i.e. does "cd FULL PATH" behave differently from "cd music"?)

@colucix

@paulsm4

Take a look at
http://www.cyberciti.biz/faq/linux-s...red-directory/
to setup a shared directory.

Kind regards

Maybe have you selinux enabled? What if you try

Code:

ls -Z /home/usr1/music

Hi again -

Quote:

bash: cd: /home/usr1/music: Permission denied

OK - it's definitely permissions

Please try this (as "root", or sudo):

Quote:

chmod ogw+rx /home/usr1/music

Then cut/paste the output of these:

Quote:

ls -ldz /home/usr1/music
mount

Thanx in advance .. PSM

Hi -

Code:

drwxr-xr-x 4 usr1 users ? 4096 Aug 23 21:51 /home/usr1/music

This indicates it *is* a directory, and *anybody* should be able to "cd" into it.

Drag

Q: Is user "usr1" able to cd into it? User "root"?

Q: Any idea what the question mark ("?") between group "users" and size "4096" might mean?

Code:

ls -l /home/usr1/ | grep music
d????????? ? ? ? ?            ? music

Q: I'm *totally* baffled about this output. Any ideas???

Q: If you have SE-Linux enabled ... would you be open to changing it to "permissive"

?

Also: please check out this link.

'Hope that helps .. PSM
