My hair is falling out already on the account of samba share issues.

  • I have an ext4 samba share on a raspberry pi, with a mask 0777 specified.
  • Only myuser on raspberry can authenticate via samba.
  • chmod -R and chown were run on the folders to fix (self-created) authorization issues.
  • myuser was added to group debian-transmission in order to access torrented files properly from my laptop.
  • From my notebook I access files with myuser with the appropriate password via samba.

Now, newly downloaded files and folders have the owner colord and group avahi-autoipd, and I cannot make sense of it. I also have only read access from the notebook. How can I fix this?

Edit: the owner on the server is debian-transmission, the owner checked with ls -l is colors, with group avahi-autopid...

Edit2: per @X Tian's comment, the uid and gid on the notebook indeed equals to user and group debian-transmission on the samba server.

  • From where do you down load & look at the actual user ID/group I'd of the downloaded files not name since it really works with id's and names are worked out by ls using /etc/passwd

    Sorry, I mean use -n option on ls to look at actual numeric id's not their name translation because passed file may have different names for those id's.

I think it could be two possible options to solve your problem.

  1. Try to add to [global] section in /etc/samba/smb.conf:

    force user = myuser
    force group = debian-transmission
  2. Second option. I'm not sure if it works, but you should try if first method fails. Add sticky bit to shared folder.

    chmod 2770 SHARED_FOLDER
    find SHARED_FOLDER -type d -exec chmod g+s {} \;
