I have a network drive service hosted on Samba(Whose settings I can't change) when I mount it on my ubuntu pc using mount.cifs I am able to read write it's content. To make a directory or file there using sudo only(My current user have sudo rights).

Mount command used is: sudo mount.cifs //address.to.samba /mnt/temp -o"username=user,password=pswd"

When the network drive is mounted on /mnt/temp/, in my php program file_exists(/mnt/temp/) returns True where as is_writable(/mnt/temp/) returns false.

The permission of /mnt/temp is initially 755. But even if I do chmod to 766 for the directory it dosen't change.

what shall I do ?

  • You should say how you are running this php, and who you think it is running as. Example: is this phone invoked as part of a web interface. – user459652 Jan 4 '19 at 8:01
  • @jdv I am running an apache server to host the php and the php is running becouse if I save it elsewhere it works fine and as well as all other things in php gives output – Shaleen Jain Jan 4 '19 at 8:50
  • -o 'uid=...,gid=...,file_mode=...,dir_mode=...,username=...,password=...'. See the manual page for mount.cifs for details. – AlexP Jan 4 '19 at 9:36
  • Thank you @AlexP It works. only if we set the dir_mode=777. please write it as a answer it will help others as well. – Shaleen Jain Jan 4 '19 at 9:54

CIFS filesystems get their owner and group from parameters of the mount command:

mount -t cifs -o 'uid=...,gid=...,file_mode=...,dir_mode=...,credentials=...'

See the manual page for mount(8) for details.

You probably want to mount the filesystem with the uid/gid under which the Apache HTTP server runs.
