=== Mounting a WebDAV Share ===


davfs2 is a file system driver that allows mounting a WebDAV server as a local file system, like a disk drive. This way, applications can access resources on a WebDAV server without knowing anything about HTTP or WebDAV. davfs2 does extensive caching to make the file system responsive, to avoid unnecessary network traffic and to prevent data loss, and to cope for slow or unreliable connections.


=== Mount WebDAV share as root (davfs2) ===


==== Installation ====
davfs2 is designed to fully integrate into the filesystem semantics of Unix-like systems (mount, umount, etc.).


On CentOS or RedHat like systems install the package davfs2 which is available in the epel repository:

WebDAV or Web-based Distributed Authoring and Versioning is an extension of the Hypertext Transfer Protocol (HTTP) allowing to access files over the internet. WebDAV access to the LSDF Online Storage is provided via a cluster of servers reachable at the address https://os-webdav.lsdf.kit.edu.



Using WebDAV from a Web Browser

To access the starting page enter the following URL in your web browser

https://os-webdab.lsdf.kit.edu/

Project directories are accessible at the usual location:

https://os-webdab.lsdf.kit.edu/kit/<OE>/projects/<PROJECTNAME>

where <OE> is the name of your organizational unit, e.g. scc, and <PROJECTNAME> ist the name of the project. Your home directory is accessible at the following URL:

https://os-webdab.lsdf.kit.edu/kit/inst/<OE>/<USERNAME>/

where <USERNAME> is you KIT username.


Using WebDAV on Linux

Mounting a WebDAV Share

davfs2 is a file system driver that allows mounting a WebDAV server as a local file system, like a disk drive. This way, applications can access resources on a WebDAV server without knowing anything about HTTP or WebDAV. davfs2 does extensive caching to make the file system responsive, to avoid unnecessary network traffic and to prevent data loss, and to cope for slow or unreliable connections.


Installation

On CentOS or RedHat like systems install the package davfs2 which is available in the epel repository:

$ yum install -y epel-release
$ yum install davfs2


Mounting a Share (as root)

To mount an LSDF WebDAV share issue the following command as root:

$ mkdir /mnt/webdav
mount.davfs https://os-webdav.lsdf.kit.edu/ /mnt/webdav >/dev/null 2>&1
Please enter the username to authenticate with server
https://os-webdav.lsdf.kit.edu/ or hit enter for none.
 Username: xy1234
Please enter the password to authenticate user fg9068 with server
https://os-webdav.lsdf.kit.edu/ or hit enter for none.
 Password:  

or

$ mount.davfs -o username=xy1234,uid=xxx,gid=yyy,rw https://os-webdav.lsdf.kit.edu/inst/projects /mnt/webdav


WebDAV mount check:

>df | grep webdav
https://os-webdav.lsdf.kit.edu/   26666664  13333332   13333332  50% /mnt/webdav

Mount WebDAV share using fstab

>cat /etc/fstab | grep webdav
https://os-webdav.lsdf.kit.edu/kit/inst/projects /mnt/webdav davfs rw,noauto,user,uid=xy1234 0 0

>mkdir /mnt/webdav 

>cat /etc/davfs2/secrets | grep os-webdav
https://os-webdav.lsdf.kit.edu/kit/inst/projects    xy1234     ***

>mount /mnt/webdav >/dev/null 2>&1

WebDAV umount:

>umount.davfs /mnt/webdav

Mount WebDAV share as user

davfs2 makes mounting by unprivileged users as easy and secure as possible.

User must be a member of the davfs2 group:

>usermod -a -G davfs2 xy1234
>grep davfs2 /etc/group

Example:

>cat /etc/fstab | grep webdav
https://os-webdav.lsdf.kit.edu/kit/inst/projects /mnt/webdav davfs rw,noauto,user,uid=xy1234 0 0

>chmod 600 /lsdf/kit/inst/xy1234/.davfs2/secrets

>cat /lsdf/kit/inst/xy1234/.davfs2/secrets | grep os-webdav
https://os-webdav.lsdf.kit.edu/kit/inst/projects  xy1234   ***

>mount /mnt/webdav >/dev/null 2>&1

>umount /mnt/webdav
umount: /mnt/webdav: umount failed: Operation not permitted

You can mount the above-mentioned WebDAV share using sudo utility.

WebDAV client cadaver

cadaver is a command-line WebDAV client, with support for file upload, download, on-screen display, in-place editing, namespace operations (move/copy), collection creation and deletion, property manipulation, and resource locking.

Using WebDAV on Windows

Add network address

Example: Computer => Add network address => Continue => https://os-webdab.lsdf.kit.edu/kit/inst/projects

Network drive over WebDAV

Examples:

>net use * https://os-webdav.lsdf.kit.edu/kit/inst/projects /user:xy1234
Laufwerk W: ist jetzt mit https://os-webdav.lsdf.kit.edu/ verbunden.
Der Befehl wurde erfolgreich ausgeführt.

or

>net use * \\os-webdav.lsdf.kit.edu@SSL\ /user:xy1234
