Upload a file

curl -T path-to-file

Download a file

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 @/
  1. Use @ to separate the account and paths. No account means anonymous user.
  2. Use : to separate the username and password of the account.
  3. Use , to separate paths.
  4. 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 -s
Password: 123456 

Use hashed password

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

Two important things for hashed passwords:

  1. Dufs only supports sha-512 hashed passwords, so ensure that the password string always starts with $6$.
  2. 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 - "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 - "GET /" 200 Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/ 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 - admin "GET /" 200
