 # webdav

-[![Build](https://img.shields.io/circleci/project/github/hacdias/webdav/master.svg?style=flat-square)](https://circleci.com/gh/hacdias/webdav)
 [![Go Report Card](https://goreportcard.com/badge/github.com/hacdias/webdav?style=flat-square)](https://goreportcard.com/report/hacdias/webdav)
 [![Version](https://img.shields.io/github/release/hacdias/webdav.svg?style=flat-square)](https://github.com/hacdias/webdav/releases/latest)
+[![Docker Pulls](https://img.shields.io/docker/pulls/hacdias/webdav?style=flat-square)](https://hub.docker.com/r/hacdias/webdav)
+
+A simple and standalone [WebDAV](https://en.wikipedia.org/wiki/WebDAV) server.

 ## Install

-Please refer to the [Releases page](https://github.com/hacdias/webdav/releases) for more information. There, you can either download the binaries or find the Docker commands to install WebDAV.
+For a manual install, please refer to the [releases](https://github.com/hacdias/webdav/releases) page and download the correct binary for your system. Alternatively, you can build or install it from source using the Go toolchain. You can either clone the repository and execute `go build`, or directly install it, using:
+
+```
+go install github.com/hacdias/webdav/v5@latest
+```
+
+### Docker
+
+Docker images are provided on both [GitHub's registry](https://github.com/hacdias/webdav/pkgs/container/webdav) and [Docker Hub](https://hub.docker.com/r/hacdias/webdav). You can pull the images using one of the following two commands. Note that this commands pull the latest released version. You can use specific tags to pin specific versions, or use `main` for the development branch.
+
+```bash
+# GitHub Registry
+docker pull ghcr.io/hacdias/webdav:latest
+
+# Docker Hub
+docker pull hacdias/webdav:latest
+```

 ## Usage

-```webdav``` command line interface is really easy to use so you can easily create a WebDAV server for your own user. By default, it runs on a random free port and supports JSON, YAML and TOML configuration. An example of a YAML configuration with the default configurations:
+For usage information regarding the CLI, run `webdav --help`.
+
+### Docker
+
+To use with Docker, you need to provide a configuration file and mount the data directories. For example, let's take the following configuration file that simply sets the port to `6060` and the directory to `/data`.
+
+```yaml
+port: 6060
+directory: /data
+```
+
+You can now run with the following Docker command, where you mount the configuration file inside the container, and the data directory too, as well as forwarding the port 6060. You will need to change this to match your own configuration.
+
+```bash
+docker run \
+  -p 6060:6060 \
+  -v $(pwd)/config.yml:/config.yml:ro \
+  -v $(pwd)/data:/data \
+  ghcr.io/hacdias/webdav -c /config.yml
+```
+
+## Configuration
+
+The configuration can be provided as a YAML, JSON or TOML file. Below is an example of a YAML configuration file with all the options available, as well as what they mean.

 ```yaml
-# Server related settings
 address: 0.0.0.0
-port: 0
-auth: true
+port: 6065
+
+# TLS-related settings if you want to enable TLS directly.
 tls: false
 cert: cert.pem
 key: key.pem

-# Default user settings (will be merged)
-scope: .
-modify: true
+# Prefix to apply to the WebDAV path-ing. Default is '/'.
+prefix: /
+
+# Enable or disable debug logging. Default is 'false'.
+debug: false
+
+# Disable sniffing the files to detect their content type. Default is 'false'.
+noSniff: false
+
+# Whether the server runs behind a trusted proxy or not. When this is true,
+# the header X-Forwarded-For will be used for logging the remote addresses
+# of logging attempts (if available).
+behindProxy: false
+
+# The directory that will be able to be accessed by the users when connecting.
+# This directory will be used by users unless they have their own 'directory' defined.
+# Default is '.' (current directory).
+directory: .
+
+# The default permissions for users. This is a case insensitive option. Possible
+# permissions: C (Create), R (Read), U (Update), D (Delete). You can combine multiple
+# permissions. For example, to allow to read and create, set "RC". Default is "R".
+permissions: R
+
+# The default permissions rules for users. Default is none. Rules are applied
+# from last to first, that is, the first rule that matches the request, starting
+# from the end, will be applied to the request.
 rules: []

+# The behavior of redefining the rules for users. It can be:
+# - overwrite: when a user has rules defined, these will overwrite any global
+#   rules already defined. That is, the global rules are not applicable to the
+#   user.
+# - append: when a user has rules defined, these will be appended to the global
+#   rules already defined. That is, for this user, their own specific rules will
+#   be checked first, and then the global rules.
+# Default is 'overwrite'.
+rulesBehavior: overwrite
+
+# Logging configuration
+log:
+  # Logging format ('console', 'json'). Default is 'console'.
+  format: console
+  # Enable or disable colors. Default is 'true'. Only applied if format is 'console'.
+  colors: true
+  # Logging outputs. You can have more than one output. Default is only 'stderr'.
+  outputs:
+  - stderr
+
+# CORS configuration
+cors:
+  # Whether or not CORS configuration should be applied. Default is 'false'.
+  enabled: true
+  credentials: true
+  allowed_headers:
+    - Depth
+  allowed_hosts:
+    - http://localhost:8080
+  allowed_methods:
+    - GET
+  exposed_headers:
+    - Content-Length
+    - Content-Range
+
+# The list of users. If the list is empty, then there will be no authentication.
+# Otherwise, basic authentication will automatically be configured.
+#
+# If you're delegating the authentication to a different service, you can proxy
+# the username using basic authentication, and then disable webdav's password
+# check using the option:
+#
+# noPassword: true
 users:
+  # Example 'admin' user with plaintext password.
  - username: admin
    password: admin
-    scope: /a/different/path
-  - username: encrypted
+  # Example 'john' user with bcrypt encrypted password, with custom directory.
+  # You can generate a bcrypt-encrypted password by using the 'webdav bcrypt'
+  # command lint utility.
+  - username: john
    password: "{bcrypt}$2y$10$zEP6oofmXFeHaeMfBNLnP.DO8m.H.Mwhd24/TOX2MWLxAExXi4qgi"
+    directory: /another/path
+  # Example user whose details will be picked up from the environment.
  - username: "{env}ENV_USERNAME"
    password: "{env}ENV_PASSWORD"
  - username: basic
    password: basic
-    modify:   false
+    # Override default permissions.
+    permissions: CRUD
    rules:
-      - regex: false
-        allow: false
-        path: /some/file
+      # With this rule, the user CANNOT access /some/files.
+      - path: /some/file
+        permissions: none
+      # With this rule, the user CAN create, read, update and delete within /public/access.
+      - path: /public/access/
+        permissions: CRUD
+      # With this rule, the user CAN read and update all files ending with .js. It uses
+      # a regular expression.
+      - regex: "^.+.js$"
+        permissions: RU
 ```

-There are more ways to customize how you run WebDAV through flags and environment variables. Please run `webdav --help` for more information on that.
+### CORS
+
+The `allowed_*` properties are optional, the default value for each of them will be `*`. `exposed_headers` is optional as well, but is not set if not defined. Setting `credentials` to `true` will allow you to:
+
+1. Use `withCredentials = true` in javascript.
+2. Use the `username:password@host` syntax.
+
+## Caveats
+
+### Reverse Proxy Service
+
+When using a reverse proxy implementation, like Caddy, Nginx, or Apache, note that you need to forward the correct headers in order to avoid 502 errors. Here's a Nginx configuration example:
+
+```nginx
+location / {
+  proxy_pass http://127.0.0.1:8080;
+  proxy_set_header X-Real-IP $remote_addr;
+  proxy_set_header REMOTE-HOST $remote_addr;
+  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+  proxy_set_header Host $host;
+  proxy_redirect off;
+}
+```
+
+## Examples

 ### Systemd

-An example of how to use this with `systemd` is on [webdav.service.example](/webdav.service.example).
+Example configuration of a [`systemd`](https://en.wikipedia.org/wiki/Systemd) service:
+
+```conf
+[Unit]
+Description=WebDAV
+After=network.target
+
+[Service]
+Type=simple
+User=root
+ExecStart=/usr/bin/webdav --config /opt/webdav.yml
+Restart=on-failure
+
+[Install]
+WantedBy=multi-user.target
+```
+
+### Fail2Ban Setup
+
+To add security against brute-force attacks in your WebDAV server, you can configure Fail2Ban to ban IP addresses after a set number of failed login attempts.
+
+#### Filter Configuration
+
+Create a new filter rule under `filter.d/webdav.conf`:
+
+```ini
+[INCLUDES]
+before = common.conf
+
+[Definition]
+# Failregex to match "invalid password" and extract remote_address only
+failregex = ^.*invalid password\s*\{.*"remote_address":\s*"<HOST>"\s*\}
+
+# Failregex to match "invalid username" and extract remote_address only (if applicable)
+failregex += ^.*invalid username\s*\{.*"remote_address":\s*"<HOST>"\s*\}
+
+ignoreregex =
+```
+
+This configuration will capture invalid login attempts and extract the IP address to ban.
+
+#### Jail Configuration
+
+In `jail.d/webdav.conf`, define the jail that monitors your WebDAV log for failed login attempts:
+
+```ini
+[webdav]
+
+enabled = true
+port = [your_port]
+filter = webdav
+logpath = [your_log_path]
+banaction = iptables-allports
+ignoreself = false
+```
+
+- Replace `[your_port]` with the port your WebDAV server is running on.
+- Replace `[your_log_path]` with the path to your WebDAV log file.
+
+#### Final Steps
+
+1. Restart Fail2Ban to apply these configurations:
+
+   ```bash
+   sudo systemctl restart fail2ban
+   ```
+
+2. Verify that Fail2Ban is running and monitoring your WebDAV logs:
+
+   ```bash
+   sudo fail2ban-client status webdav
+   ```
+
+With this setup, Fail2Ban will automatically block IP addresses that exceed the allowed number of failed login attempts.

networkException	79bc17afab	feat: add support for systemd listener activation sockets To support starting a network service on demand and to support a "least privilege-approach" with regards to the permission a network service process needs to have, systemd supports opening a network socket on behalf of the service and passing it as an open file descriptor. The service gets notified about open file descriptors for this purpose as well as metadata such as named listeners via environment variables. This patch adds support for prefixing the listen address passed with --address with "sd-listen-fd:" to access these file descriptors, taking either a listener name passed using the `LISTEN_FDNAMES` environment variable or `LISTEN_FD_$n` for unnamed file descriptiors where `n` is the id of the descriptor starting at 3 (LISTEN_FD_3).
