### 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.
**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:
```sh
$ openssl passwd -6 123456 # or `mkpasswd -m sha-512 123456`
$6$tWMB51u6Kb2ui3wd$5gVHP92V9kZcMwQeKTjyTRgySsYJu471Jb1I6iHQ8iZ6s07GgCIO69KcPBRuwPE5tDq05xMAzye0NxVKuJdYs/
```
Use hashed password:
```sh
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:
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.
```sh
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.
| $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:
```yaml
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](https://github.com/sigoden/dufs/tree/main/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
