caddy-webdav's Issues

Run as unprivileged user

Hi,

This webdav module is working extremely well with a few lines of configuration, congratulations for the awesome job 🏆

One issue I'm facing now is that file manipulations done via webdav are done with the permissions of the user Caddy runs as (which is root when using Docker).

I'd love to be able to configure another user to perform file manipulations as, probably following the user[:group] or uid[:gid] format like this:

webdav.{$BASE_URL} {
  webdav {
    root /share/
    user mike:mike
  }
}

Using Docker or Docker Compose, it would even be configurable like this:

webdav.{$BASE_URL} {
  webdav {
    root /share/
    user {$UID}:{$GID}
  }
}

Do you think that might be considered?
Or should I gosu/su-exec the whole Caddy server instead?
Or do you recomment another solution?

Thanks a lot in advance 🙏

encoded url can escape path limit

add "..%2F" to url can get the parent of root path

FR: hide option

i would love to hide a folder on webdav listening. something like the hide option in file_server.

405 Method not allowed on default configuration

Clean download (from https://caddyserver.com/download) and installation of Caddy2+webdav on Mac OS Catalina.

Browser gets status code 405 and shows Method not allowed for https://localhost/dav, with Caddyfile extracted from Readme as below,

localhost

root * /srv

route {
rewrite /dav /dav/
webdav /dav/* {
prefix /dav
}
file_server
}
<<<

If replaced it with below (basically remove rewrite and prefix), everything works with http://localhost URL.

localhost
root * /srv
route {
webdav {
}
file_server
}
<<<

Cannot find any clues anywhere :(... please kindly share any advices. Thanks.

How to have WebDAV server run under a subdirectory of a subdomain?

I'm having some trouble setting this up. I want:

A file browser web interface running on cloud.example.com
This WebDAV server running under cloud.example.com/dav

How can I do this?

I tried this, but it didn't work:

drive.example.com {
    webdav /dav/* {
        root /srv/files
        prefix /dav
    }
}

It gives me a blank screen when I navigate to drive.example.com/dav.

Thanks for the awesome work. There is an issue trouble me when I use this module. Large file can not be upload to the webdav server even caddy and caddy-webdav start normally. However, small file can be uploaded and deleted, and large file can alse be deleted. And all is well if basicauth is not set, similar to the issue mentioned here. Here is my detailed info:

v2.4.6 h1:HGkGICFGvyrodcqOOclHKfvJC0qTU7vny/7FhYp9hNw=

my Caddyfile

{
    email [email protected]
    order webdav before file_server

webdav can not work in caddy v2

I want use webdav with caddy v2, but can not work.

caddy version: 2.1.1
My website root: /home/website, webdav root: /home/webdav

Caddyfile:

{
  http_port 8080
  order webdav last
}
http:// {
  root * /home/website
  log {
    output stdout
  }
  file_server
  webdav /webdav/* {
    root /home/
  }
}

When file_server is normal, the website can be accessed, but WebDAV cannot work.
The comment file_server, WebDAV works normally and the website cannot be accessed.

Permission/Path issues with webdav-module using systemd service

Hi,

first of all, thanks a lot for the webdav-module. :) I had some trouble getting things to run smoothly and thought it might be a good idea to share the solutions.

Background: I wanted to use webdav to store and share notes with my wife. I encountered the following problems while installing, which my have occurred to others.

My system: Debian Buster running caddy v2.3.0 h1 with a systemd service (I swapped the executable in /usr/bin/ with the one including the webdav module).

Things that were not clear for me from the webdav module readme:

1. get the root right:
The readme example does not work with the systemd service.
Read-me example:

webdav /some/path/match/* {
	root /path
	prefix /some/path/match
}

I had to change it to:

        webdav /webdav/* {
           root /usr/share/caddy/webdav
           prefix /webdav
        }

In my case the webserver root in the caddyfile is root * /usr/share/caddy, which means that the path structure of the example is different.

2. Fix permissions while using a systemd service:
Although caddy had all the necessary permissions to the webdav directory it still complained about permissions:
Feb 18 23:18:48 vps caddy[12627]: {"level":"error","ts":1613686728.1413567,"logger":"http.handlers.webdav","msg":"internal handler error","error":"open /usr/share/caddy/webdav/silentnotes_repository.silentnotes: read-only file system","request":{"remote_addr":"x.x.x.x:123","proto":"HTTP/1.1","method":"PUT","host":"x.x.com","uri":"/webdav/silentnotes_repository.silentnotes","headers":{"Content-Length":["832"],"Authorization":["Basic c3xlZmAuOlYySXIxZg=="],"Accept-Encoding":["gzip, deflate"]},"tls":{"resumed":false,"version":771,"cipher_suite":49200,"proto":"","proto_mutual":true,"server_name":"x.x.com"}}}

Fix: Follow https://caddy.community/t/problem-with-filemanager-plugin-and-systemd/3900/3 and add a ReadWriteDirectories directive to the systemd file, as ProtectSystem=full prevents this.
In my case this results in:

User=caddy
Group=caddy
ExecStart=/usr/bin/caddy run --environ --config /etc/caddy/Caddyfile
ExecReload=/usr/bin/caddy reload --config /etc/caddy/Caddyfile
TimeoutStopSec=5s
LimitNOFILE=1048576
LimitNPROC=512
PrivateTmp=true
ProtectSystem=full
AmbientCapabilities=CAP_NET_BIND_SERVICE
ReadWriteDirectories=/usr/share/caddy/webdav

If you find these notes useful, please add them to the module read-me page. Thanks!

Can not build with the new Go version

Hello,

I can not build / install the Webdav plugin for Docker.
I've tried numerous times.

I've tried to update my GO version with this tutorial:
https://go.dev/doc/install

This is the error message:
18.94 go: github.com/mholt/[email protected] requires go >= 1.22.0 (running go 1.21.10; GOTOOLCHAIN=local) 18.94 2024/05/22 02:58:06 [FATAL] exit status 1

go version:
go version go1.22.3 linux/amd64

Please help.

root directive appears to ignore {http.auth.user.id}

I am trying to setup a multi-user WebDAV configuration.

I have things configured in the Caddyfile as follows:

*.example.com {
   ...
   @storage host storage.example.com
   handle @storage {
      basicauth {
         username1 <hashed_pw>
         username2 <hashed_pw>
      }
      root * /path/to/webdav/{http.auth.user.id}
      webdav
   }
   ...
}

Which is working, but the individual users see the root of the webdav path when they connect (i.e. /path/to/webdav/, not /path/to/webdav/user1 as expected.)

It appears someone else ran into the same issue, as posted here:
https://caddy.community/t/multiple-users-with-different-roots-in-webdav/19502

But they never replied to the debugging suggestions.

As suggested, I turned on debugging and tried the custom X-Auth header. From that, I can see the username from {http.auth.user.id} as expected in the response.

Other than that, there don't appear to be any debug messages indicating a problem.

I'm not hugely familiar with go, but I also took a look at the Caddyfile parsing code for this module, and it all looks pretty straightforward and boiler-platey, so it doesn't seem likely the issue would be there.

Any ideas?

How to use webdav on caddy docker

Hello! Friend.

I use this caddy. https://hub.docker.com/_/caddy?tab=description
But webdav can not work.
Can you help me ?

Thank you very much.

Can you add the modify option like cdday-v1-webdav? It can achieve read-only access

Every time you use webdav to sync photos, an error will be reported，

Caddy server is windows 10. The phone uses photosync+webdav to synchronize photos, and an error will be reported every time a photo is synchronized.

Error message： Cannot create a file when that file already exists

Tip: The error log will be output, but it does not affect the use

Caddyfile：

{
	order webdav before file_server
}

:7001 {
	webdav {
		root D:/_data
		prefix /
	}
}

error.log：

{"level":"error","ts":1627832105.3054144,"logger":"http.handlers.webdav","msg":"internal handler error","error":"mkdir D:\\_data\\手机相册\\Screenshots\\2020: Cannot create a file when that file already exists.

How to set up a basic webdav server.

Not compatible with MacOS Finder

I have Caddy with this module configured and it is working fine for iPhone KeePassium.

For MacOS, I am using KeePassXC, which does not support webdav directly, so I have to mount the directory with MacOS Finder.

It lists the files, but I cannot create or rename files, so KeepassXC cannot save the database. I also tried create and rename directly in the Finder and it does not work.

After some investigation, it looks like MacOS requires the webdav server to support "Level 2 locking". Apache can do that and Nginx with some workarounds, but looks like this module does not.

I tried various configs, including the standard:

        webdav /dav/* {
                root /dav/
                prefix /dav
        }

HEAD requests should work also on folders

HEAD requests to folders return HTTP 405 Method Not Allowed.

I believe this is an issue because, according to RFC 4918§9.4, HEAD should be valid also on collections.

The current behaviour makes it impossible to use this extension with some WebDAV clients/libraries (e.g., java's Sardine).

Multiuser/scope support is missing in the new webdav addon

Scopes as provided by the webdav "predecessor" addon in caddy 1.0.4 is not available in caddy 2 (2.2.1)

I used the following config in caddy 1.0.4 which worked just as wanted. Couldn't get similar mult user access functionality in caddy 2 and the new webdav addon.

webdav.somedomain.duckdns.org {
	basicauth / super userpwd
	basicauth / user2 userpwd
	basicauth / user3 userpwd
	basicauth / user4 userpwd
	webdav {
		super:
		scope /home/DATA/webdav
		user2:
		scope /home/DATA/webdav/.user2
		user3:
		scope /home/DATA/webdav/.user3
		user4:
		scope /home/DATA/webdav/.user3
	}
	log /etc/caddy/access-webdav.log
}

Separately publish executable files for caddy with webdav plugin.

Separately publish executable files for caddy with webdav plugin.
https://github.com/mholt/caddy-webdav/releases

Since webdav requires higher performance than static files and reverse proxy, I think webdav should be run as a separate process, and then it would be better for caddy gateway service to do reverse proxy for webdav.

It is better to separate the gateway service and webdav service into separate processes.

Compiling caddy with plug-ins still has some costs. Wouldn't it be better to publish it as an executable file?

In this way, you can get a webdav server out of the box.

Document prefix option

The readme doesn't document the prefix option at the moment, which is required whenever a matcher is used on the directive.

I spent an hour or two of confusion before finding the option in the code, documenting it might save the next person some time. :D

Empty response from Caddy + Webdav

Webdav with Jetbrains Rider, Caddy and ASP NET Core Umbraco CMS

Hi,
I have these settings as default in webdav:

danobe.dev {
        # Set this path to your site's directory.
        #root * /usr/share/caddy

        # Enable the static file server.
        #file_server

        # Another common task is to set up a reverse proxy:
        reverse_proxy localhost:5000

        # Or serve a PHP site through php-fpm:
        # php_fastcgi localhost:9000
}

I tried by know all different choices with webdav and tutorials in the internet, but I can't get it to work.

This are the fields I have to enter in the image.
I'm not really familiar with webdav, it seems to be the only convinient way to deploy my application.

I have a linux server with the path /var/www/personalWebsite into which I would like to deploy my application.

It works via scp and rsync but it looks like I'm to dumb to get it to work with debdav.

Could you provide a clear explanation on how I have to change the caddy configuration file?

Like I've said I tried all possible combinations but I couldn't get it to work...

And how do I restrict the access, is this like a public ftp where everyone can deploy files?
I've read this here, and here it get's shown I have to create a password hash, but I don't know if this is necessary?

That would be very kind of you,

PROPFIND of file that does not exist

When receiving a PROPFIND request for a file that does not exist, the plugin is logging an internal handler error, instead of responding appropriately, which I imagine would be with a 404.

TLS and Webdav client

Hi there, apologies, this is completely off topic.

Have you ever been able to access a webdav server via caddy with TLS 1.2?

I have tried cadaver, davx, thunar (the file manager) but they all seem to send a TLS 1.0 Client Hello and that fails with the current Caddy.

Thank you, just wondering because I am going a bit nuts :D

Excuse me, how to set different permissions under multiple users?

For example, user 1 has read, write, edit and delete permission, while user 2 has only read permission.

Make Missing Caddy 1 WebDav Plugin features available

Hello,

Are there plans to expose features available in https://github.com/hacdias/caddy-webdav, such as blocking dot files, allowing modifications for files/folders per user, or allowing/denying user access to resources, for Caddy 2?

I am currently using Caddy v1.

Trying to confirm if it's working

I wanted to see if you could clarify something in my Caddyfile, or maybe build. I cannot get /webdav to work with a docker build of Caddy. When I browse to the docker box, I get my test page. When I go to http://dockerip/static to redirect to /static/ and does the browse plugin. So those are working. When I go to http://dockerip/webdav I'm getting 404.

Is the root element of webdav relative to the site blocks root? or is it a full file path?

My Caddyfile:

{
    order webdav last
}

(global) {
  encode gzip zstd
  log {
    output file /data/logs/caddy_access.log
  }
  handle_errors /data/logs/caddy_errors.log
  php_fastcgi phpfpm:9000
}

:80 {
  root * /usr/share/caddy/html
  file_server
  file_server /static/* browse
  import global

  redir /static /static/

  webdav /webdav {
    root /usr/share/caddy/webdav
  }
}

The Dockerfile builder:

FROM caddy:2.0.0-builder AS builder

RUN caddy-builder \
    github.com/mholt/caddy-webdav

FROM caddy:2.0.0

COPY --from=builder /usr/bin/caddy /usr/bin/caddy

Is it possible to have directory listing with WebDAV enabled in the same path?

Based on the documents and my test, it seems like WebDAV has to be served in a different path with directory listing, one cannot have them both functioning under the same path, is that correct?

As an Apache & Nginx user, I felt quite surprised, as it is an expected behaviour to have them working in the same path.

Cheers,
Jayden

Permissions error with one file prevents listing the whole directory

I think this is a bug or limitation in the upstream webdav library, but I noticed that when listing the contents of a directory, the whole request returns an error if just one of the files has a permissions error. Instead, that file should not be in the list, and the request should still succeed, listing the rest of the files in the directory.

Issue with webdav RANGE requests

Hello,

I tired using caddy webdav plugin as backend for the excellent rclone project, and indeed was working somewhat fine for small files, however i discovered that there is a problem related to the RANGE request and downloads failing for big files and having to-download that lead me to rclone issue #4459 comment by @ncw, it seems there is problem related to the range requests in webdav plugin causing the multipart download files to not send correct range the file real size is 875607573 or 836M. As far as i know single request downloads works fine.

The webdav service filter some files for unknown reason

The caddy and webdav module is downloaded today from the homepage.

Caddyfile :

{
    admin off
    auto_https off
    local_certs
    order webdav before file_server
}

:9999 {
    encode gzip
    root * /data      
    file_server browse
    tls /root/caddy/server.cert /root/caddy/server.key

    webdav /webdav/* {
        root /data
        prefix /webdav
    }
}

Step 1

Generate some text files as the snapshot, then refresh the webdav directory, no any text file is shown.

Step 2

Then, just rename the text file to another filetype as the snapshot, and refresh the webdav directory again, one of them appeared.

Step 3

Let's continue. This time i just rename the filename, did not change the filetype. Here is the snapshot.

Step 4

Not only text files is filtered strangely, other filetype is the same. Here is another test.

This is my webdav client conf:

I dont know why and how to resolve it. Thanks.

LOCK/UNLOCK and other Webdav method support

Hi there, really liking caddy and learning a bunch, while trying to contribute a bit! To the forum.

I was wondering if you see this plugin evolving so that it can support class 1 or class 2 WebDAV.

My current need does not involve anything fancy but it would be nice to stay with caddy if the need for a lock, for instance, arises.

Thanks for your effort!
