Installing the command-line executable

Assuming you have Rust/Cargo installed, run this command in a terminal:

cargo install dufs

It will make the dufs command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall dufs uninstalls.

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 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.

There are no restrictions on using ':' and '@' characters in a password. For example, user:pa:ss@1@/:rw is valid, the password is pa:ss@1.

Hashed Password

DUFS supports the use of sha-512 hashed password.

Create hashed password

$ mkpasswd -m sha-512 123456
$6$tWMB51u6Kb2ui3wd$5gVHP92V9kZcMwQeKTjyTRgySsYJu471Jb1I6iHQ8iZ6s07GgCIO69KcPBRuwPE5tDq05xMAzye0NxVKuJdYs/

Use hashed password

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

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
