I have configured Samba 3.4.7 with extended attributes enabled to preserve file create/modify dates. In the [global] section of smb.conf: ea support =yes store dos attributes =yes map archive = no map readonly =no The map hidden and map system are ignored when I check with testparm. In the share section I have: create mask =0771 directory mask =0771 I also checked the share directory and applied chmod 771 to match the directory permissions to Samba settings and allow the minimal permissions for the attributes mapping. I went ahead and tried to map a network drive, and successfully copied a file over to samba, though the create date is set to the modified date on the copy. When I check the extended attributes of the file I copied over with: sudo getfattr -d -encoding=text [share directory] I see one attribute: user.DOSATTRIB For my /etc/fstab, I have set the following options set for a ext4 filesystem: auto,relatime,errors=remount-ro,user_xattr Is there a way to check the contents of user.DOSATTRIB? I am not seeing any obvious error messages in the samba log file, do I need to patch the Ubuntu 10.04 kernel or switch to Samba 3.4.7 to store file create/modify information? Derek
