WebDAV

Description

WebDAV is a protocol to manage your site directly from MS Windows Explorer, Mac OS, Linux and so on. Plone supports WebDAV without add-ons, and Plone responds to WebDAV requests out of the box.

Introduction

WebDAV is enabled by default in Plone. A Plone server listening on port 8080 will also accept WebDAV traffic on that port.

Note

WebDAV historically was used mainly for uploading files in bulk to Plone. In Plone 5, this functionality comes standard. For earlier versions, he add-on collective.wildcardfoldercontents provides this.

Connecting to Plone via WebDAV

For common cases, client-side tools should work reasonably well.

Permissions

The “WebDAV access” permission is required for any user to be able to connect to WebDAV.

To allow Plone users (ie. users created within a Plone site, as opposed to users created in Zope) to connect using WebDAV, go to the Security tab of the Zope (e.g. http://yoursite:8080/manage_access), find the permission “WebDAV access”, check the box for it under the Anonymous column, and press the Save Changes button. This generally grants WebDAV connection access. Normal Plone permissions will take care of who can view or change actual content.

Enabling WebDAV on an extra port in Zope

You can have Plone listen for WebDAV requests on additional ports by modifying your buildout configuration’s client setup to add a WebDAV address:

Here is a short buildout.cfg example:

[instance]
...
recipe = plone.recipe.zope2instance
...
webdav-address=1980
...

Here is an alternative buildout.cfg configuration snippet which might be needed for some WebDAV clients:

[instance]
...
zope-conf-additional =
    enable-ms-author-via on
    <webdav-source-server>
    address YOUR_SERVER_PUBLIC_IP_ADDRESS_HERE:1980
    force-connection-close off
    </webdav-source-server>

These snippets will be in the generated parts/instance/etc/zope.conf after buildout has been re-run.

This will enable the WebDAV server on http://www.mydomain.com:1980/.

Note

You cannot use this URL in your web browser, just in WebDAV clients.

Using the web browser will give you an error message AttributeError: manage_FTPget. You could also just run the WebDAV server on localhost with address 1980, forcing you to either use a WebDAV client locally or proxy WebDAV through Apache.

Disabling WebDAV

You can’t disable WebDAV in Plone itself; it’s tightly integrated in Zope. You could take away the “WebDAV access” permission from everyone, but the Zope server will still answer each request.

What you can do is make your web server filter out the WebDAV commands; this will stop WebDAV requests before they reach your Zope server.

Nginx

For nginx, this is done by adding:

dav_methods off

to the server block in your nginx.conf. (http://wiki.nginx.org/HttpDavModule)

If you do not use the HttpDavModule, you can add:

limit_except GET POST {
 deny   all;
}

to the location block.
