CHMOD on smb share reverts back after 5 mins

[lintech]

I have a samba share directory /home/stuff which I chmod to 771 to allow group access, however the directory reverts back to 711 permissions after 5 mins. Any ideas?? (mandrake 2005)

Are you changing this on the samba server, or from a remote box? Are the share permissions being changed or the file permissions?

[lintech]

Changing the permissions on the share directory from the server.

This allows you access from windows, however 5 mins later you can't access the share directory because the permissions on the directory have changed back. Any idea what is causing the permissions to change back?

Are you using lines like those ones in your /etc/samba/smb.conf:

create mask = 0771
directory mask = 0771

?

See

man smb.conf

for more.

so far no joy, will try and simplify things tomorrow and see if I can have any luck. Thanks.

msec (Mandriva Linux Security package) manages homedir permissions by default, forcing to be 711 for obvious security reasons.

Solutions:

1 - Move this directory from under /home.

or

2 - Tell msec the permissions you want for this directory.

The second alternative is done by adding one of the following lines to /etc/security/msec/perm.local (which one depends on your desire to force change or maintain the current directory owners):

/home/stuff desireduser.desiredgroup 711

or

/home/stuff current 711

It's possible that the file /etc/security/msec/perm.local doesn't exist. Create it then.

Thanks for that hchasqueira, that seems to be working nice. I have noted that solution down and squirrelled it away for next time.

At least you get 5 minutes! Take a look at this:

[root@Hounslow john]# chmod -v 777 /mnt/win_c3

mode of `/mnt/win_c3' changed to 0777 (rwxrwxrwx)

[root@Hounslow john]# chmod -v 777 /mnt/win_c2

mode of `/mnt/win_c2' changed to 0777 (rwxrwxrwx)

[root@Hounslow john]# ls -l /mnt

total 24

drwxr-xr-x 2 root root 4096 Sep 10 14:12 cdrom/

drwxr-xr-x 2 root root 4096 Sep 10 14:12 floppy/

drwxr-xr-x 2 root root 8192 Jan 1 1970 win_c2/

drwxr-xr-x 2 root root 8192 Jan 1 1970 win_c3/

[root@Hounslow john]#

I have 2 shares (both entire 9.1GB disk drives) win_c2 and win_c3
but they seem to be obstinately readonly. As you can see above, using chmod to change the permissions makes no difference.
