Personal Storage

The TUM provides a Network-Attached-Storage (NAS) which can be accessed by all students, staff and guests of the TU München. Users need a valid LRZ account.

Every user has a personal part of the NAS for his/her exclusive use. Administrators can create new project related storage folders and set access rights for people within a department or a small project group or even for groups that are from different departments of the university.



NAS is supported for all offical Windows versions XP or later (the NAS should also work with Windows 95, 2000 or NT but these versions have no offical support from the LRZ).

You can use the Explorer and choose the menu "Extras -> Netzlaufwerk verbinden". Your personal folder is located at \\\ab12cde where ab12cde is your LRZ-account. Shared project folders of the NAS can be found at \\\tuph\ucl where tu is the TU München, ph the department of physics and ucl the Universe-Cluster.

User is ads\ab12cde and password your MyTUM password (ads is the information of the Windows domain!).

You can also use the command line to do this

net use x: \\\ab12cde <password> /USER:ADS\ab12cde


In MacOSX you can use "Finder" and "Mit Server verbinden...". You have to type the NAS address with a smb://-prefix, e.g. smb:// Then user and password have to be given (see section on Windows).


command line access is possible via

mount -t cifs //<sharename> </my/path> -o username=<lrz-account>,domain=ADS


mount -t cifs // /home/weiss/nas -o username=ab12cde,domain=ADS

password has to be given at the command line.

nautilus (GNOME)

There are many alternative file browsers and tools to access this network share. For example Ubuntu 8.10/gnome: use "Places-> Connect to server" and choose "Windows share". Fill the data for server (, folder (e.g. ab12cde), User name (ab12cde), and domain name (ADS). For fast access you can set a bookmark. In the newer versions of Ubuntu (>= 13.04), the file manager was simplified. Now you have to enter the server as smb://, click continue, and then enter domain, user name and password.

dolphin (KDE)

In the location bar, enter for example


then enter ADS\ab12cde as username and your password.


If you have administration rights to your system you can also add the following line to your /etc/fstab:

//<lrz-account> </my/path> cifs uid=<id-on-your-computer>,username=<lrz-account>,domain=ADS

You can then mount the nas folder with the following command:

sudo mount /my/path

This will first ask the password for sudo and then the password for your lrz account.

On Ubuntu, you will have to install the cifs-utils package first via

sudo apt-get install cifs-utils

Without it, you will get error messages that are difficult to understand. Of course, something similar may apply to other distributions.


The file server creates so-called snapshots every four hours, which are stored for several days. After that, one snapshot per day is kept, which after one month drops to weekly snapshots. Unfortunately, these snapshots can only be accessed using Microsoft Windows.

To access the snapshots for a file or folder, right-click on it, open the properties dialog and select the tab labeled "Older Versions". From there you can select to restore a previous state or copy a previous version to a different location.

Shared Storage

we also have different parts of shared storage (e.g. for administration, for the different Junior Research Groups, for all cluster members …). This shared space can be found at \\\tuph\ucl . There are four main folders Administration, Scientific Coordination, Public Outreach and Science. Science has sub folders for the different Junior Research Groups, a place for some software and hints that may be helpful for you and a folder called "shared" where you can exchange files across different research groups.
