Access Control

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

dufs -a admin:admin@/:rw -a guest:guest@/
dufs -a user:pass@/:rw,/dir1 -a @/

Use @ to separate the account and paths. No account means anonymous user.
Use : to separate the username and password of the account.
Use , to separate paths.
Use path suffix :rw/:ro set permissions: read-write/read-only. :ro can be omitted.

-a admin:admin@/:rw: admin has complete permissions for all paths.
-a guest:guest@/: guest has read-only permissions for all paths.
-a user:pass@/:rw,/dir1: user has read-write permissions for /*, has read-only permissions for /dir1/*.
-a @/: All paths is publicly accessible, everyone can view/download it.

Auth permissions are restricted by dufs global permissions. If dufs does not enable upload permissions via --allow-upload, then the account will not have upload permissions even if it is granted read-write(:rw) permissions.

Hashed Password

DUFS supports the use of sha-512 hashed password.

Create hashed password:

$ openssl passwd -6 123456 # or `mkpasswd -m sha-512 123456`
$6$tWMB51u6Kb2ui3wd$5gVHP92V9kZcMwQeKTjyTRgySsYJu471Jb1I6iHQ8iZ6s07GgCIO69KcPBRuwPE5tDq05xMAzye0NxVKuJdYs/

Use hashed password:

dufs -a 'admin:$6$tWMB51u6Kb2ui3wd$5gVHP92V9kZcMwQeKTjyTRgySsYJu471Jb1I6iHQ8iZ6s07GgCIO69KcPBRuwPE5tDq05xMAzye0NxVKuJdYs/@/:rw'

The hashed password contains $6, which can expand to a variable in some shells, so you have to use single quotes to wrap it.

Two important things for hashed passwords:

Dufs only supports sha-512 hashed passwords, so ensure that the password string always starts with $6$ .
Digest authentication does not function properly with hashed passwords.

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
dufs --hidden '*.log' --hidden '*.lock'

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

Configuration File

You can specify and use the configuration file by selecting the option --config <path-to-config.yaml>.

The following are the configuration items:

serve-path: '.'
bind: 0.0.0.0
port: 5000
path-prefix: /dufs
hidden:
  - tmp
  - '*.log'
  - '*.lock'
auth:
  - admin:admin@/:rw
  - user:pass@/src:rw,/share
  - '@/'  # According to the YAML spec, quoting is required.
allow-all: false
allow-upload: true
allow-delete: true
allow-search: true
allow-symlink: true
allow-archive: true
enable-cors: true
render-index: true
render-try-index: true
render-spa: true
assets: ./assets/
log-format: '$remote_addr "$request" $status $http_user_agent'
log-file: ./dufs.log
compress: low
tls-cert: tests/data/cert.pem
tls-key: tests/data/key_pkcs1.pem

Customize UI

Dufs allows users to customize the UI with your own assets.

dufs --assets my-assets-dir/

If you only need to make slight adjustments to the current UI, you copy dufs's assets directory and modify it accordingly. The current UI doesn't use any frameworks, just plain HTML/JS/CSS. As long as you have some basic knowledge of web development, it shouldn't be difficult to modify.

Your assets folder must contains a index.html file.

index.html can use the following placeholder variables to retrieve internal data.

__INDEX_DATA__: directory listing data
__ASSETS_PREFIX__: assets url prefix
