minor error with smb mount

[firwareslut]

The owner of the files is the same. Same name and same id.


adam@main:/media/NETWORKHD$ touch ok

I simulated it on my spd8020 mounting the public share from the nwsp2
and indeed you cannot change the permissions from the machine that did the mount, even not after changing owner (1000 matches with the username used to mount the share)

(/share/1000/192.168.1.197-smb-public is the mountpoint on the spd8020 of the nwsp2 public share)

Code: Select all

root@SPD8020:/share/1000/192.168.1.197-smb-public # ls -oal test.tar
-rw-r--r--  1 root 541184 Nov 14 21:09 test.tar

root@SPD8020:/share/1000/192.168.1.197-smb-public # chmod 666 test.tar
chmod: changing permissions of `test.tar': Permission denied

root@SPD8020:/share/1000/192.168.1.197-smb-public #
root@SPD8020:/share/1000/192.168.1.197-smb-public # ls -oal test.tar
-rw-r--r--  1 1000 541184 Nov 14 21:09 test.tar

root@SPD8020:/share/1000/192.168.1.197-smb-public # chmod 666 test.tar
chmod: changing permissions of `test.tar': Permission denied


so now I can simulate your problem i can have a closer look, must be something with samba settings

[firwareslut]

Ok thanks! Appreciate it!

when accessing the same share via windows explorer then I can change in explorer the file permissions when the username as used to login to windows fits with owner of the file. Explorer uses the samba server.
That means that it must be a mounting parameter

[firwareslut]

hehe yeah but what? I cannot make it work at all.

Indeed it seems there be a problem with the samba server settings. Little additional test, I mounted a public share with the login "root" server and I get the same message.

The fact that the user "root" is the only one to be defined with a valid shell, is not the problem. So something to look on the server side.

[fvdw]

On the other hand there is something contradicting this , that is when using the same samba server you can change permission of a file using windows explorer in case the owner of the file and the windows username is the same.
The share public is just a samba share mounted by windows. Just try it. If you can then change permissions of a file in a samba share via explorer then it means the server settings allow it, so it must be the way the share is mounted by the client

I enabled a shared samba folder on my media pc with the same login named and mounted the drive on the client pc in the same way as I mounted the NAS. I can change file permissions on the media PC no problem at all. It has to be a configuration issue on the NAS.

Are the perms actually being modified by explorer if you check directly on the NAS?

[fvdw]

I change the permissions with explorer and verified it on the NAS via ssh access

below a screen shot from windows7 when making the change.
PS again it only succeeds if the username of windows7 matches with the owner of the file as sored on the NAS
I checked if the permissions are really changed on the NAS and that is the case

on windows 7 explorer before making the change

then remove write access permission and save

On the Nas you see now this

With XP you can't do that (and I don't know about vista)
