Mount a webdav share with Rclone on FreeBSD
We have an internal intranet Apache based web server, serving files using WebDav to different client types here at SoCruel.NU. The web server is configured with SSL/TLS using a certificate signed with a private Certifcate Authority.
The following technical prerequisites have to be in place to be able to implement what is described in this post:
- an up to date and supported FreeBSD system version 12.2 or higher
- the system must be able to access the internet using the DNS, HTTP and HTTPS protocols (i.e. to be able to fetch and install software).
- have a Apache based web server, serving files using WebDav with Basic authentication configured!
For this post we asume that the user account who mounts the remote WebDav share is
Not many tools are out there to be able to connect to, use or even mount a WebDav based share on FreeBSD. But luckily I found Rclone! And it is available in the FreeBSD ports as well. What more do you need!
Rclone is a command line program to manage files on cloud storage. And it also supports WebDav, besides loads of more cloud based storage platforms! The documentation is clear and very good, so go over to the Rclone website and read what it is capable of! It is a lot and amazing.
Prepare the system
Before we can implement Rclone, we have to prepare our system a bit. We will perform the following actions:
- create an empty directory to mount our WebDav share on
- make sure that users can mount a remote file syetem on our system
- load the
So first we create the empty directory which
mike mounts the WebDav share on and we make the
mike user account the owner:
$ sudo mkdir /mnt/webdav $ sudo chown mike:mike /mnt/webdav
To make sure a normal user can mount a remote file syetem we have to set a system control:
$ sudo sysctl vfs.usermount=1 vfs.usermount: 0 -> 1 $ sudo tee -a /etc/sysctl.conf > /dev/null <<EOT ? vfs.usermount="1" ? EOT
$ sudo sysrc kld_list+=fuse $ sudo kldload fuse
Install private CA certificate
The WebDav share is configured with SSL/TLS using a certificate signed with a private Certifcate Authority.
So we have to get this private Certifcate Authority certificate on our system, such that Rclone will not complain.
We assume here that the file name of this Certifcate Authority certificate is
ca.cert.pem and that it is available on an internal web site
http://ca.internal.domain.tld. We then can
fetch the certificate and add it to the trusted store of our system:
$ cd /usr/local/share/certs $ sudo fetch http://ca.internal.domain.tld/ca.cert.pem . $ sudo chmod 0444 ca.cert.pem $ sudo certctl rehash
$ sudo pkg install -y rclone
In the second step we add a ‘remote’ configuration. For this Rclone configuration we assume the following:
- the URL for our WebDav share is:
- the Rclone name of this ‘remote’ is:
Te create a Rclone configuration we just issue the command
rclone config and answer the questions we get. This will create a
rclone.conf file in the
.config/rclone directory in the home directory of the user:
$ rclone config 2021/03/18 11:19:45 NOTICE: Config file "/home/mike/.config/rclone/rclone.conf" not found - using defaults No remotes found - make a new one n) New remote s) Set configuration password q) Quit config n/s/q> n name> webdavshare Type of storage to configure.

The Rclone config file
~/.config/rclone/rclone.conf looks like:
$ cat ~/.config/rclone/rclone/rclone.conf [webdavshare] type = webdav url = https://webdav.intra.domain.tld/webdavshare vendor = other user = mike pass = ENCRYPTED OBSCURED PASSWORD
pass value, the password, in the configuration file is obscured using
base64. For more information on this see rclone obscure.
$ rclone lsd webdavshare:/
Mount the WebDav share
$ rclone mount webdavshare:/ /mnt/webdav --vfs-cache-mode writes --daemon
And that is it. We can now access our files at
