samba-3.x versus samba-2.x - file permissions

[skarg]

Hello,

I recently created a ubuntu-server to replace a debian-stable server that I was using for samba in order to increase storage. It is just a local file server on my home LAN. Samba-3.x acts differently than samba-2.x, and I am having trouble with permissions.

For example, I insert a compact flash card connected to a USB reader on my kubuntu workstation, and copy a file to the samba server. The file on the CF card shows rwx------ permissions. After it is copied to the samba server, the workstation shows/obeys the same permissions, even though my fstab file is configured to show the samba mount files as rw-rw-rw- and the samba server has some force permission settings.

The actual samba server filesystem shows the file as rwxrw--rw-. I have turned off unix extensions both on the samba server and turned off Linux extensions on the kubuntu workstation, but that only solved the UID/GID issue, not the permissions. If I umount/mount the share on the workstation, the permission from /etc/fstab take effect.

How do I get samba 3.x to behave like 2.x where it would keep/report the group permissions as I force them?

Best Regards,

Steve

from /etc/fstab on kubuntu-dapper workstation:
//vader/data /mnt/data cifs auto,rw,guest,uid=nobody,gid=users,dir_mode=02777, file_mode=0666,nosetuids,noperm,directio,noacl 0 0

from /etc/samba/smb.conf on ubuntu-server dapper:

[global]
security = share

[global]
server string = %h server (Samba, Ubuntu)
security = SHARE
obey pam restrictions = Yes
passdb backend = tdbsam
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* .
syslog = 0
log file = /var/log/samba/log.%m
max log size = 1000
unix extensions = No
dns proxy = No
panic action = /usr/share/samba/panic-action %d
invalid users = root
csc policy = disable

[data]
comment = Common Data Directory
path = /home/skarg/data
force user = nobody
force group = users

create mask = 0666
force create mode = 0666
directory mask = 02777
force directory mode = 02777
inherit permissions = Yes
guest ok = Yes

I finally got it working like I wanted, and thought I would post the results.

First - both were running samba 3.x, one was on debian, one on ubuntu server.

So, I just copied the /etc/samba/smb.conf file from the old server and just modifed the share names, and voila! It was working again.

Here is the /etc/samba/smb.conf file that worked. I used the command "testparm" to show it without comments.


[global]

invalid users = root

[homes]
comment = Home Directories
read only = No

[cdrom]
comment = Samba server's CD-ROM
path = /cdrom
guest ok = Yes
locking = No
preexec = /bin/mount /cdrom
postexec = /bin/umount /cdrom

[data]
comment = Common Data Directory
path = /home/skarg/data
force group = users
read only = No
create mask = 0666
force create mode = 0666
directory mask = 02777
force directory mode = 02777

My /etc/fstab entry on the clients look like this:


//vader/data /mnt/data cifs auto,rw,guest,uid=nobody,gid=users,dir_mode=02777, file_mode=0666 0 0
