= The WebDav Service =

 * Web Distributed Authoring and Versioning (WebDAV) is an extension of the Hypertext Transfer Protocol (HTTP) that facilitates collaboration between users in editing and managing documents and files stored on World Wide Web servers. 
   The WebDAV protocol makes the Web a readable and writable medium. It provides a framework for users to create, change and move documents on a server; typically a web server or web share.

== HOWTO use WebDav ==
 * WebDav can be used under windows, linux or MAC. We always can access in read mode to our file repository using a web browser, and seting in the address: https://pool01.ifca.es, (remember tha IFCA only supports https).

=== Windows ===
 
 * To enable the read/write mode, we need to mount the network device under Windows.
 
  1. Select Computer

=== Linux ===
 * Under linux we can access in read/write mode using to different access
   1. The [[http://www.webdav.org/cadaver/|Cadaver]] client
       Cadaver is a command-line WebDAV client for Unix. It supports file upload, download, on-screen display, namespace operations (move/copy), collection creation and deletion, and locking operations.

   1. Mount WebDav as a regular file systemed using [[http://savannah.nongnu.org/projects/davfs2|davfs2]]
    * Under Debian or Ubuntu
      {{{
      sudo apt-get install davfs2
}}}
    * Under RedHat
      {{{
      yum install davfs2
}}}    
    1. Add your user to davfs2 group
      {{{
      sudo usermod -a -G davfs2 username
      dpkg-reconfigure davfs2  (If you want to mount the resource as user instead of root)
}}}
    1. Create the mount directory
      {{{
      sudo mkdir /mnt/WebDav
}}}
    1. Mount the file system
    * Volatil
      {{{
      sudo mount.davfs 'https://pool01.ifca.es' /mnt/WebDav
      username@laptop:~$ sudo mount.davfs 'https://pool01.ifca.es' /mnt/WebDav
      [sudo] password for username:

      verify the fingerprint! The server might be faked
      or there might be a man-in-the-middle-attack.

}}}
    * Permanet (edit /etc/fstab anf add the following line)
      {{{
      https://pool01.ifca.es /mnt/WedDav   davfs   user,rw,noauto   0   0
}}}
      Then 
      {{{
      mount /mnt/WedDav
}}}

=== Common Issues ===
  
  1. If you get the error '''file exits'''
       Edit /etc/davfs2/davfs2.conf and add:
       '''use_locks       0'''
  1. If the files disappear from webdav directory
       Edit /etc/davfs2/davfs2.conf and add:
       '''if_match_bug    1'''
