Zugriffsrechte
Modify access rights on own files/home directory
1. General
Every student has a folder accessible via /u/halle/$USER.
$USER is the CIT-Login received from the Infopoint and used to log in to the computer hall.
In this folder, you can find different architectures, such as HomeAT, for the Ubuntu VMs used by LxHalle.
To facilitate student collaboration, most of those folders can be accessed by other students.
Important folders like the home_mail and homesec are only visible and writable by the active user.
These notes are explicitly valid only for the lxhalle.
