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.

AFS for Linux-Users

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

AFS for Windows-Users

For a windows user 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

Access Problems

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.
A solution was found by Lena: Solution

Daily Backup

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\

User Directories

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)

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

  /afs/math.uni-hamburg.de/groups/it
Backup:
