AFS network file system

AFS (Andrew File System) is the network filesystem at the department of Mathematics. The home-directories live there as well as the homepage-directories.
Unix- and Windows systems use the same filesystem. It is also possible to install the AFS on Mac OS X-Systems, Notebooks, self-maintained or private computers and use it also from home.

Your home quota is restrained to 25 GB of storage. The command fs quota displays the percentage of used quota. If more quota is required, please sent a well-founded request to the IT-Group.

• For Linux
• For Windows
• For Mac OS X

Your home-directory with your data lies at:

/afs/​math.uni-hamburg.de/​users/​GROUP/IDENTIFIER/​
e.g. /​afs/​math.uni-hamburg.de/​users/​it/​fmnv165

Your WWW-homepage lies at:

/​afs/​math.uni-hamburg.de/www/​home/SURNAME/​
e.g. /afs/math.uni-hamburg.de/​www/​home/​xyz​
or: /afs/math.uni-hamburg.de/​users/​GROUP/IDENTIFIER/​public_html

For windows users the path to the home-directory lies at:

\\afs\math.uni-hamburg.de\users\GROUP\IDENTIFIER\
e.g. \\afs\math.uni-hamburg.de\users\it\fmnv165\

Your WWW-homepage lies at:

\\afs\math.uni-hamburg.de\www\home\SURNAME\
e.g. \\afs\math.uni-hamburg.de\www\home\xyz
or: \\afs\math.uni-hamburg.de\users\GROUP\IDENTIFIER\public_html

You can enter these paths directly in the address bar of the Windows-Explorer (the app with a yellow folder-symbol, not the Internet Explorer!) or – if you need to access the folders regularly – you can add a drive letter by right clicking on “This PC” and then “Map network drive”

• Mozilla-profiles under Windows
• For Linux-users all configurations incl. profiles in AFS are automatically available

When a new user account is added to a computer, sometimes this account can't access the AFS after being logged in to the computer.

For all directories stored in the AFS a daily backup is performed. In this way its always possible to access yesterdays version of your data. The 'public'-tree directories are also backuped daily in the AFS but are not hard-linked. If data from the 'public'-tree is needed please contact the IT-Group

Important On Windows the following paths must be modified. Each slash '/' must be replaced by a backslash '\' and the backslash at the beginning of the path must be doubled.

Example: /afs/math.uni-hamburg.de/users/it/fmsv030/ has to be written as: \\afs\math.uni-hamburg.de\users\it\fmsv030\

Home-Directory:

Directory:
  /afs/math.uni-hamburg.de/users/<Group>/<RRZ-Identification>/
  /afs/math.uni-hamburg.de/users/it/fmsv030/
Backup:
  /afs/math.uni-hamburg.de/users/<Group>/<RRZ-Identification>/AFSBAK/
  /afs/math.uni-hamburg.de/users/it/fmsv030/AFSBAK/

WWW-Home-Directory:

Directory:
  /afs/math.uni-hamburg.de/www/home/<Surname>
  /afs/math.uni-hamburg.de/www/home/peters/
Backup:
  /afs/math.uni-hamburg.de/AFSBAK/www/home/<Surname>
  /afs/math.uni-hamburg.de/AFSBAK/www/home/peters

Public-Directory:

  /afs/math.uni-hamburg.de/public/<RRZ-Identification>
  /afs/math.uni-hamburg.de/public/fmsv030

• Normally, Home-Directories are readable only by the owner.
• WWW-Directories can be accessed via WWW but normally only by their owner.
• Public-Directories can normally be read by all users (worldwide!).

Normally, because the owner can modify the access rights for his directories. (e.g. expand rights (permissions) for the Home-Directory or reduce rights (permissions) for the Public-Directory)

WWW-Directory:

Directory:
  /afs/math.uni-hamburg.de/www
Backup:
  /afs/math.uni-hamburg.de/AFSBAK/www

Group-Directories:

Directory:
  /afs/math.uni-hamburg.de/groups/<Group>
  /afs/math.uni-hamburg.de/groups/it
Backup:
  /afs/math.uni-hamburg.de/groups/AFSBAK/<Group>
  /afs/math.uni-hamburg.de/groups/AFSBAK/it

<Group> in the path means the abbreviation of the research areas like: ad, az, dd, dm, oa, st
