Advanced topics

Access Control

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

dufs -a [user:pass]@path[:rw][,path[:rw]...][|...]

Multiple rules are separated by "|"
User and pass are the account name and password, if omitted, it is an anonymous user
One rule can set multiple paths, separated by ","
Add :rw after the path to indicate that the path has read and write permissions, otherwise the path has readonly permissions.

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

admin has all permissions for all paths.

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

guest has readonly permissions for all paths.

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

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

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

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

dufs -A -a user:pass@/dir1:rw,/dir2:rw,dir3

user has all permissions for /dir1/* and /dir2/*, has readonly permissions for /dir3/.

dufs -a admin:admin@/

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

Hide Paths

Dufs supports hiding paths from directory listings via option --hidden <glob>,....

dufs --hidden .git,.DS_Store,tmp

The glob used in --hidden only matches file and directory names, not paths. So --hidden dir1/file is invalid.

dufs --hidden '.*'            # hidden dotfiles
dufs --hidden '*/'            # hidden all folders
dufs --hidden '*.log,*.lock'  # hidden by exts

Log Format

Dufs supports customize http log format with option --log-format.

The log format can use following variables.

variable	description
$remote_addr	client address
$remote_user	user name supplied with authentication
$request	full original request line
$status	response status
$http_	arbitrary request header field. examples: $http_user_agent, $http_referer

The default log format is '$remote_addr "$request" $status'.

2022-08-06T06:59:31+08:00 INFO - 127.0.0.1 "GET /" 200

Disable http log

dufs --log-format=''

Log user-agent

dufs --log-format '$remote_addr "$request" $status $http_user_agent'

2022-08-06T06:53:55+08:00 INFO - 127.0.0.1 "GET /" 200 Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36

Log remote-user

dufs --log-format '$remote_addr $remote_user "$request" $status' -a /@admin:admin -a /folder1@user1:pass1

2022-08-06T07:04:37+08:00 INFO - 127.0.0.1 admin "GET /" 200
