Hello !

Getting a bit annoyed with permission issues with samba and sshfs. If someone could give me some input on how to find an other more elegant and secure way to share a folder path owned by root, I would really appreciate it !

Context

  • The following folder path is owned by root (docker volume):

/var/lib/docker/volumes/syncthing_data/_data/folder

  • The child folders are owned by the user server

/var/lib/docker/volumes/syncthing_data/_data/folder

  • The user server is in the sudoers file
  • Server is in the docker groupe
  • fuse.confhas the user_allow_other uncommented

Mount point with sshfs

sudo sshfs server@10.0.0.100:/var/lib/docker/volumes/syncthing_data/_data/folder /home/user/folder -o allow_other

Permission denied

Things I tried

  • Adding other options like gid 0,27,1000 uid 0,27,1000 default_permissions
  • Finding my way through stackoverflow, unix.stackexchange…

Solution I found

  1. Making a bind mount from the root owned path to a new path owned by server

sudo mount --bind /var/lib/docker/volumes/syncthing_data/_data/folder /home/server/folder

  1. Mount point with sshfs

sshfs server@10.0.0.100:/home/server/folder /home/user/folder

Question

While the above solution works, It overcomplicates my setup and adds an unecessary mount point to my laptop and fstab.

Isn’t there a more elegant solution to work directly with the user server (which has root access) to mount the folder with sshfs directly even if the folder path is owned by root?

I mean the user has root access so something like:

sshfs server@10.0.0.100:/home/server/folder /home/user/folder -o allow_other should work even if the first part of the path is owned by root.

Changing owner/permission of the path recursively is out of question !

Thank you for your insights !

    the user as full root access

    Are you sure? The “sudoers” file only applies to commands you run with the “sudo” command. Which is not being run here that I can see.

      Hii !

      Ohh maybe I misunderstood the sudoers file. I though having the sudo commands gives you actually full control over your system? Am I wrong?

      Do you have any tips or workaround for my specific use case?

      Thank you :)
