We have installed a simple webdav server + elliptics backend for you to test, you can connect using your favorite client and check how POSIX filesystem works.
For Linux we recommend using wdfs and definitely not dvfs2, the latter is very racey and basically doesn’t work. For Windows to enable network drive support with authentication you will have to install webdav client (wrapper actually) which supports this, default Windows webdav client doesn’t support auth, we recommend NetDrive.
Here is a linux setup:
sudo wdfs http://webdav.reverbrain.com:8021/webdav /mnt/webdav/ -o uid=1000,gid=1001,umask=0022,username=test,password=test,allow_other
Where uid/gid should correspond to your local user. Username/password is test/test.
Please note, that this node can be (and will be) destroyed/reset at any moment.
