| 11 | Every student has a folder, which can be accessed via /u/halle/$USER . | ||
| 12 | |||
| 13 | $USER is the CIT-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. | ||
