I'm running Samba 2.2.8a on SuSE Linux 8.1 with kernel 2.4.19. I have a share defined by this on a web server to allow members of the jamigos group to edit web pages.
[users] comment = User Web Pages path = /home valid users = @jamigos read only = No create mask = 0664 force create mode = 0664 directory mask = 0775 force directory mode = 0775 browseable = No
I received a few complaints of save errors followed by missing web pages so I decided to check it out. Via this share, I opened the file /home/wasdnord/public_html/4133/1RIGHT.HTM with Mozilla. Here were the permissions at the filesystem level ahead of time. The group jamigos is one of my supplementary groups.
drwxrwsr-x+ 2 wasdnord jamigos 104 Sep 21 11:38 ../4133 and stat shows permissions of 2775.
-rw-rw-r--+ 1 wasdnord jamigos 2334 Oct 16 2003 1RIGHT.HTM
and stat shows 0664.
I made a small change, added a word to the bottom of the file, and tried to save it. This gave me the rather generic error of "Saving File failed!" via Mozilla Composer. I looked at the file on the server to see this:
-rw-rw-r--+ 1 wasdnord jamigos 0 Sep 21 12:00 1RIGHT.HTM
What was being reported to me as missing pages was actually files having their contents erased.
I deleted the file and saved again, this time with no problems yielding:
-rw-rw-r--+ 1 joines jamigos 2626 Sep 21 12:19 1RIGHT.HTM.
It's not an issue of file permissions as I can make the changes with vi directly on the filesystme with no problem. It's not an editor issue as I tried both Mozilla and Kate on Linux whereas the problems reported to me were with a wide variety of editors including frontpage on windows. Once I own the file, it all works as expected.
Just before trying this I turned the log level up to 3 and here's what I got:
[2004/09/21 11:59:43, 3] smbd/dosmode.c:unix_mode(111) unix_mode(wasdnord/public_html/4133/1RIGHT.HTM) returning 0664

Naturally, there was tons of other stuff in the log at this level so I'm not even sure if these errors in the log are related to this particular problem.
Any ideas?

It gets even more bizarre. I have another share for access to non-user web sites by a variety of editors. It is set up like this:
[web]
comment = Web Server
path = /local/htdocs
browseable = No
read only = No
create mask = 0664
directory mask = 0775
A directory and file I need to edit looks like this:
drwxrws--x+ 14 joeblow cbaweb 20480 Sep 24 16:47 undergraduate/
-rw-rw-r--+ 1 joeblow cbaweb 2434 Sep 24 16:47 undergraduate/studentorganizations.php
I have access to this directory and files via the admin group and ACLs.
getfacl undergraduate/ # file: undergraduate # owner: joeblow # group: cbaweb user::rwx group::rwx group:admin:rwx mask::rwx other::--x default:user::rwx default:group::rwx default:group:admin:rwx default:mask::rwx default:other::--x
getfacl undergraduate/studentorganizations.php # file: undergraduate/studentorganizations.php # owner: joeblow # group: cbaweb user::rw- group::r-- group:admin:rwx #effective:rw- mask::rw- other::r--
Now, using VI on the actual filesystem I can edit this file all I want to and everything behaves as expected. However, using any editor via Samba I can only edit the file once, the second time it blanks it and sets it to zero bites.
This is a repeatable situtaion:
Open the file, add a character, save, all is well.
Add another character, save, get editor specific errors and a zero byte file.
I removed the ACLs and added myself to the owning group, cbaweb. I can still edit just fine locally. However via SMB I now get the same editor specific error but the file is not zeroed. I just can't change it.
Don't know if it's relevant or not but I'm using posixgroups stored in OpenLDAP.
Any ideas anyone?
