Dear all,
Im trying to set up Samba so that linux users can use the new unix
extensions to be able to chmod their files as they wish. However I
seem to be having problems with masks.
Whether using smbfs or smbclient trying to do: chmod 777 testfile
results only in read permissions for group and other (ie it ends up
744). Under smbfs it complains:
chmod: changing permissions of `testfile' (requested: 0777, actual:
0744): Operation not permitted
The only way I can it to work is to set "create mask = 0777" in the
server's smb.conf. Now, this is confusing me as the file isnt being
created, I'm just trying to chmod an existing file. I dont want to
leave the setting as this because of course all new files get created
with world read-write which is not what I want.
Looking at the unix_perms_from_wire() function, it would seem it is
indeed applying the create mask.
As an aside, changing permissions from a W2K ACL dialogue seems to work fine.
Any ideas anyone?
Samba version: 3.0.4
Some relevant settings from smb.conf:
# testparm -v | egrep '(force|security|mask|unix extensions)'
Load smb config files from /usr/local/samba/samba-3.0.4/lib/smb.conf
Processing section "[homes]"
