Samba, Dolphin client

jnoake · 10-02-2015, 02:43 PM

To the point -
On a linux samba client (4.1.6-201.fc22), Dolphin, browsing a samba share does not show the real 'Permissions,Owner,User Group'
it shows all FOLDERS as drwxr-xr-x fred fred
and sows all FILES as -rwxr--r-- fred fred
(current user is fred)

More information;
I have Samba server installed on Fedora 3.19.8-100.fc20.
the relevant smb.conf sections follow:

Code:

[global]
        workgroup = WORKGROUP
        server string = Samba Server Version %v
        hosts allow = 127. 192.168.55.0/255.255.255.0
        log file = /var/log/samba/%m.log
        max log size = 50
        security = user
        map to guest = Bad User
        preferred master = yes
        wins support = yes
        restrict anonymous = yes
        domain master = yes
        logon home = \\%25N\%25U
        logon path = \\%25N\%25U\profile
        client ntlmv2 auth = yes
        client plaintext auth = yes
        client lanman auth = yes
        lm announce = Yes

[upload]
        comment = Files will be re-named and moved to the Media Library. Junk will be deleted.
        path = /var/shared/upload
        writable = yes
        hide dot files = no
        valid users = fred, bob
        create mask = 0640
        directory mask = 0750
        force group = upload

fred and bob are both members of group upload.

For the most part this works as I expect, fred and bob can both create files and folders that the other can read but not write to or delete.
Creating files/folders and then looking at the servers file system shows the expected user, group and permissions.

Can this be explained?
Can I fix it?

Did you set /var/shared/upload ownership yet? Linux system permissions take precedence over Samba permissions.

Reference:

Code:

chgrp upload /var/shared/upload && chmod g+s /var/shared/upload

Thanks ferrari, for your reply.

I had not done this, but the share was still accessible.
I have now run this command - I can see the sense, but it has not changed the observed behaviour of the Dolphin/samba client.

Dolphin is still lying about the permissions and ownership within the share.

Interestingly, Windows shows the permissions correctly which implies that it is not a samba server problem, but a samba client or Dolphin problem.

I will install and try some other file managers and see what they report.

Krusader shows the same as Dolphin.

but...

If I mount the samba share and navigate to it using Konsole, I can see the numeric user and group ID's (which are valid on the server, obviously not on the client) and the permissions are also correct.

... so it is not like the smb client is not potentially providing the information to file managers.

I think that is normal. Unix permissions are not the same as Samba permissions. I can only relate to a remote share I need access for work. If I examine directory and file permissions via my Dolphin file manager, I get 'User: dean, Group: users'. This is regardless of who created the directories/files. My samba username is different as well.

This might help answer some of the confusion about expected permissions

My apologies if I don't get what you're trying to convey.
