You can easily mount a WebDAV filesystem on Linux so that you can access the files just like they were on your local computer. One way to do is to install the davfs2 package (this is the Ubuntu/Debian package name, though it should be similar for other distros). Once you have installed it, add an entry to /etc/davfs2/secrets with your login credentials for the WebDAV account. For box.net, the command would look like this:

sudo echo “https://www.box.net/dav username password” >> /etc/davfs2/secrets

You need to choose a mountpoint on your local filesystem for the WebDAV mount. In this example I am going to use /mnt/box.net, so go ahead and create the directory:

mkdir /media/box.net

Now add an entry to /etc/fstab for this filesystem, which will allow you to automatically mount it at boot time. If you want your normal user (instead of just root) to have write access, specify your uid (username) and gid (can be the same as your username) on the mount line along with your newly-created mountpoint:

https://www.box.net/dav /mnt/box.net    davfs   defaults,uid=username,gid=username  0       0
