[Samba] permission bit headache

[dave selby]

Hi all,

I am configuring a samba server on kubuntu 7.04, samba 3.x but am
having permission bit problems. I have googled, read, experimented but
am still stuck. I am trying to allow the permissions to be set on the
files in my shares without restriction, so I have set various masks to
no avail. This is my configuration and problem ...

With the samba server running on my machine, and a need for me to
access it I wrote the following script that starts up after the samba
server has started.

# To get round running samba server and access samba on same machine
# and to make the mounting process bombproof
smb_mount() {

declare -i i=0
until cat /etc/mtab | grep //127.0.0.1/$1 &> /dev/null ||  [ $i -ge 3 ]; do

    mount -t smbfs //127.0.0.1/$1 /mnt/$1 -o
credentials=/home/dave/.smbpw,uid=dave,gid=dave,fmask=$2,dmask=$3,lfs
    sleep 2
    i=$i+1
done
}

smb_mount common 0777 0777 &
smb_mount windows 0777 0777 &
smb_mount archive 0777 0777 &
root at dave-desktop:~#

It mounts my three shares as /mnt/common ... windows & archive as
expected. (the whole timing loop thing is because sometimes samba has
not fully started up at this point) With a /etc/profile umask of 077

drwxrwxrwx 1 dave dave 4096 2007-06-28 18:45 .

dave at dave-desktop:/mnt/common$ ls -al
total 16
drwxrwxrwx 1 dave dave 4096 2007-06-28 18:45 .

-rwxrwxrwx 1 dave dave    0 2007-06-28 19:08 test
dave at dave-desktop:/mnt/common$

kind of expected test to have permissions of
-rw-------

dave at dave-desktop:/mnt/common$ chmod a-rwx test
dave at dave-desktop:/mnt/common$ ls -al
total 16
drwxrwxrwx 1 dave dave 4096 2007-06-28 18:45 .
drwxrwx--- 5 root dave 4096 2007-06-27 22:37 ..
drwxrwxrwx 1 dave dave 4096 2007-06-25 18:32 film
drwxrwxrwx 1 dave dave 4096 2007-06-25 18:35 music
-r-xr-xr-x 1 dave dave    0 2007-06-28 19:08 test
dave at dave-desktop:/mnt/common$

so why are there still r & x bits set ?


Its probarbly best if I show you my smb.conf file - any help much
appreciated. I have already setup ...

    create mode = 0777
    directory mode = 0777
    force create mode = 0
    force directory mode = 0
    security mask = 0777
    force security mode = 0
    directory security mask = 0777
    force directory security mode = 0

in [global] to try and enforce open permission bits, though most are
supposed to default to non restrictive masks.

Any help or pointers would be very much appreciated :)

Cheers

Dave
