[gentoo-user] Mount permissions

[gentoo-user] Mount permissions

[Paul Stear]

The root of all my rsync/network problems is a permissions problem
The /mnt/network is
drwxrwxrwx  3 root root  4096 Mar 13 13:24 test

After I mount using
mount -t smbfs -o 
username=paul,password=pass //LKG7DDD5F/gentoobackup /mnt/network

the /mnt/network permissions have change to

drwxr-xr-x  1 root root 0 Mar 13 16:57 test

How do I ensure the permissions stay the same after the mount

type man mount or man mount.cifs.

Once in man, press / which will let you search.  Now type smbfs and hit
enter.  You should see the options for smbfs.  The interesting ones are:

uid
gid
umask
fmask/file_mode
dmask/dir_mode

uid will let you set a user id for all files

gid will let you set a group id for all files

umask remove umaks bits.  for example if you mount with umask=000,
everything will be 777 or rwx.

fmask/file_mode set the mas for files

dmask/dir_mode set the mask for directories

If you are mounting win2k or higher, you should use cifs.  This is how I
mount my C$ share on my WinXP laptop:

mount -t cifs -o
username=administrator,gid=100,file_mode=0660,dir_mode=0770
//laptop/C$ /mnt/laptop

The above is should be one line.  This will mount my laptops C$ share
and give permission for everyone in the users group to read/write/execute.

If you need to mount < win2k then you would change cifs to smbfs,
file_mode to fmask and dir_mode to dmask.

snip all

Hi,
The mystery gets deeper, every time I mounted the network storage server disk 
and rsync'd I had a lot of errors.  It appears that the mount point was 
changing permissions every time I mounted.
I want all of the directories and files to retain the original privileges 
during the rsync.
Anyway after tearing my hair out (whats left of it) I realised that after a 
umount my mount point /mnt/network was still connected, the umount said that 
the mount point was disconnected.
Overtired, frustrated and baffled I switched off the box and went to the land 
of dreams.
Today as soon as the box had booted I checked /mnt/network and The network 
storage discs were connected.
I don't know How and Why this is automatically happening  --  can anybody give 
me any clues?

I am rsync'ing at the moment with no errors but the backup is in the wrong 
directory on the network usb disc, so I need to understand how this device is 
automatically mounted so I can change the directory.

Thanks for all who have helped so far

Paul
