4 The Databar System at DTU 1 Introduction The purpose of this guide is to introduce new users to the databar system at DTU and provide basic information about the G-Databar 1 and the Winbar. Furthermore, Section 3 describes the university portal (intranet) and Campusnet (the information center which covers the DTU curriculum). To keep all this information compact and overseeable for you, many instances below refer to further details available at the G-Bar web site: http://www.gbar.dtu.dk and at the Winbar web site: http://www.winbar.dtu.dk. An overview of the databars at DTU can be found at http://www.databar.dtu.dk. 2 Databar system The objectives of the databar system at DTU are to make the full range of applications and computer power available to students and researchers regarding the curriculum, writing and computing needs in connection with research, work projects, and other study activities. 2.1 The physical databars The DTU databar system consists of a number of databars spread on the DTU area, see Table 1 on the facing page. The map on the last page of this guide shows the location of these databars. Terminals and printers can be accessed from the databars, and since all of the databars are connected within the same system, it is possible to access one’s own files at any of them. All databars must conform with certain requirements of the network program and software which makes it possible to connect the databars, and which ensures that at least the minimum of software is accessible everywhere. In the UNIX and Linux databars, you have the possibility to connect to a Windows Desktop (Remote Desktop) 2 . Similarily, you can start a UNIX or Linux desktop in the Windows databars (ThinLinc). 2.2 Use of mobile devices Provided that you have a wireless network adaptor in your mobile computer, you can use your own mobile device as a thin client 3 (the UNIX system). After installing a ThinLinc client (described in Section 5 on page 6) you can use your mobile device just like any other thin client on campus. 1 G-Databar is also called G-Bar 2 For more information, go to http://www.gbar.dtu.dk/wiki/Windows_FAQ 3 The thin clients are the terminals that are available for use in the G-Bar and in some of the other databars. See table 1.

The eduroam network is the free, wireless network of the universities for the students and the employees. With eduroam you will also be able to access the wireless net of other universities in Denmark and abroad. However, the configuration of eduroam depends on operating system (Windows, Linux, MacOS), and you may have to install a program in order to access the wireless network with eduroam. For more information on eduroam, please consult the G-Bar wiki (http://www.gbar.dtu.dk/wiki/eduroam). Alternatively, you can use the net called “dtu”. In order to authenticate, you will need to enter your credentials every time you log on to this wireless network, which is quite cumbersome. “dtu” is also not encrypted, which means that people can eavesdrop on your communication and hijack for example your Facebook account. For these reasons, we recommend using eduroam instead. For more information on the wireless networks, please see www.wireless.dtu.dk.
