Advanced topics

Access Control

Dufs supports path level access control. You can control who can do what on which path with --auth/-a.

dufs -a <path>@<readwrite>
dufs -a <path>@<readwrite>@<readonly>
dufs -a <path>@<readwrite>@*

• <path>: Protected url path
• <readwrite>: Account with readwrite permissions. If dufs is run with dufs --allow-all, the permissions are upload/delete/search/view/download. If dufs is run with dufs --allow-upload, the permissions are upload/view/download.
• <readonly>: Account with readonly permissions. The permissions are search/view/download if dufs allow search, otherwise view/download..

dufs -A -a /@admin:admin

admin has all permissions for all paths.

dufs -A -a /@admin:admin@guest:guest

guest has readonly permissions for all paths.

dufs -A -a /@admin:admin@*

All paths is public, everyone can view/download it.

dufs -A -a /@admin:admin -a /user1@user1:pass1 -a /user2@pass2:user2

user1 has all permissions for /user1* path. user2 has all permissions for /user2* path.

dufs -a /@admin:admin

Since dufs only allows viewing/downloading, admin can only view/download files.
