============================================================

Ok, the partitions stuff is the (all)most simplest there is:
2 disks with 1 partion each (ext3).
/* not completely true: the hda has a second partition used for swapping, but this doesn't matter */
- 8Gb disk (hda) which is the 'systemdisk'.
- 80Gb disk (hdb) which is the 'central filedisk'.
With other words: mp3's, movies and homedirs on the hdb. All os and programs+config on the hda.

Since the hdb has financial administration stuff of a choir and more stuff not meant for my brothers/others I have made a directory /mnt/public/
Here I mount everything I would like to be public for all house members. This way I can add and remove shares without touching the smb.conf (think that's

less risky :)

So here the whole story in short (df -h & mount):
Code:
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda1            7.4G  606M  6.5G  9% /
/dev/hdb1              74G  5.5G  65G  8% /mnt/centrale
none                  62M    0  62M  0% /dev/shm
/mnt/centrale/audio    74G  5.5G  65G  8% /mnt/public/audio
/mnt/centrale/video    74G  5.5G  65G  8% /mnt/public/video


/dev/hda1 on / type ext3 (rw)
none on /proc type proc (rw)
usbdevfs on /dev/pts type devpts (rw,gid=5,mode=620)
none on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/hdb1 on /mnt/centrale ype ext3 (rw)
none on /dev/shm type tmpfs (rw)
/mnt/centrale/audio on /mnt/public/audio type none (rw,bind)
/mnt/centrale/video on /mnt/public/video type none (rw,bind)
============================================================

After installing the packages I did:
The user definitions:
Code:
groupadd vk26all
groupadd vk26parents
groupadd vk26brothers
useradd -d /mnt/centrale/homes/paul -G vk26all paul
passwd paul
useradd -d /mnt/centrale/homes/corawillem -G vk26all,vk26parents cora
passwd cora
useradd -d /mnt/centrale/homes/corawillem -G vk26all,vk26parents willem
passwd willem
useradd -d /mnt/centrale/homes/wilco -G vk26all,vk26brothers wilco
passwd wilco
useradd -d /mnt/centrale/homes/steven -G vk26all,vk26brothers steven
passwd steven
The rights-idea behind this:
  • All users in this house may read-only from the '/mnt/public map' ([VK26] in the smb.conf)
  • The users paul, wilco and steven have a centralized 'my documents' on the network ([Documenten] in the smb.conf)
  • The users cora en willem have together a centralized 'my documents' on the network ([Documenten] in the smb.conf)
  • The user paul (me) has read-write acces to the whole '/mnt/centrale' ([VK26Admin] in the smb.conf)

Making the smbpasswd:
Code:
smbpasswd -a paul
smbpasswd -a cora
smbpasswd -a willem
smbpasswd -a wilco
smbpasswd -a steven
Editing some config files:
Code:
vi /etc/services

The result (in the network neightbourhood):

Logged in as Paul:
Sees the following shares:
Documenten
  • Asks for password when opening the share (supplying the correct password, results in being asked again, and again, ....)
VK26
  • Opens correct
  • Reading files is possible
  • Complains about accessrights when trying to write
VK26Admin
  • Opens correct
  • Reading files is possible
  • Writing files is possible

Logged in as Steven:
Sees the following shares:
Documenten
  • Asks for password when opening the share (supplying the correct password, results in being asked again, and again, ....)
VK26
  • Opens correct
  • Reading files is possible
  • Complains about accessrights when trying to write
VK26Admin
  • Asks for password when opening the share (supplying the correct password, results in being asked again, and again, ....)

Everything is correct, except the [documenten] share.

The users *are* listed in the /etc/samba/smbpasswd.
The user's homedirectories *are* listed in the /etc/passwd.
So *why* do I keep getting the password prompt for the documents share?

Sight...

============================================================

In case somebody can figure this out, here is part of the samba-log.txt.
It shows the /etc/rc.d/init.d/smb start and steven trying to open (1 try) the [documenten] share

lol, the ':' and the 'o' are interpeted as :o...
... Nevermind you know what is says :)

============================================================

Ok, I can't *believe* I left any mistery for you.
Still *I* don't have a *clue* why things don't work out.

Please,.. enlight me!

ThNx for your time,

GrTzzz....

remove the valid users = %u. You can put guest ok = no.

Well, you do have the share configured as read only. You should also make sure that the unix permissions allow selected users or groups to write to the file. You can also put a parameter called "write list" to allow selected users to write to the share whereas everyone else can read.

This is the 2nd one where steven logs in. Since steven is the one logging in, even though he puts his correct password, he is not allowed to log in because he is not a valid user.

Cheers

BTW, what OS are you using to connect to samba?

paulvl 09-10-2003 07:34 PM
Whoohoo,

the "remove the valid users = %u. You can put guest ok = no." did the trick.
I still don't get why 'valid users' was incorrect, but things are working now.

About the os question:
The main client is the Win98 pc. But since my vk26parents are asleep :) (2:30 here in the netherlands) I tested it on the WinXP pc. Everything works fine there so I'm confident it wil be fine for the Win98 too.

Thanks a *lot* man.

Learned some things about samba that I will benifit for quite a while.

Still a little questions pop's up in my mind: If an users creates a file on a public = yes, writable = yes share: what's the result with the linux-rights (owner and chmod stuff)?

sidmark-2850 09-10-2003 09:23 PM
If you do "testparm", there are defaults for the "create mask" and "directory mask." They are 744 and 755 respectively. So therefore a user will be able to create files, but he is the only one who can modify or delete them. If you wanted to make a public writable folder, you should first create the directory with the 777 permissions, then create the samba share as follows:
Code:
[Public]
        comment = Public Writable Share
        path = /mnt/public2
        public = yes
        read only = yes
        create mask = 0666
        directory mask = 0777
This way, all users will be able to write to the share.
