LSDF Online Storage: WebDAV

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/

where <OE> is the name of OE. Your home directory is accessible with the following URL:

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

where <USERNAME> is you username.

Using WebDav on Linux

Mount WebDAV share as root (davfs2)

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

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:

>yum install -y epel-release
>yum install davfs2

>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.
