11 Every student has a folder, which can be accessed via /u/halle/$USER .
12
13 $USER is the ITO-Login, which was received from the Infopoint and is used to login into the computer hall.
14
15 In this folder you can find different architectures like home//at for the Ubuntu VMs for the lxhalle.//
16
17 In order to facilitate the collaboration of students, most of those folders can be accessed by other students.
18
19 Important folders like the home_mail and home//sec are only visible and writeable by the active user.//
20
21 These notes are explicitly valid only for the lxhalle.
