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]" Loaded services file OK.
