Use of own computer in the Internet transmitted courses at CBS


In general terms any modern UNIX (also Linux) or MacOS X computer will do as is. Windows hosts will typically need a minor installation effort. The details of the required functionality are as follows:

  • Internet connection, at least 5 mbit/s (not phone modem!).

    Comment: if your Internet connection is too slow it becomes practically impossible to follow the course.

  • Internet browser e.g. IE, Netscape, Mozilla, Safari etc.

    Comment: almost all the teaching will be via HTTP: lectures, presentations, exercise instructions and discussion fora.

  • Secure shell (ssh) client software able to tunnel to an X-server software (see below).

    Comment: the computer exercises on the course will be performed on the CBS servers. The only allowed access is by ssh. All modern UNIX (also Linux and MacOS X) installations include an ssh client by default. For Windows hosts we recommend PuTTY. It can be downloaded from here (choose the latest 'putty-xx-installer.exe' file for Intel x86). All PuTTY software is freeware. Remember to enable X forwarding when defining your session.

  • X-server software.

    Comment: after logging in you will need to execute X programs on the CBS servers and display the results on your own computer. All modern UNIX (also Linux and MacOS X) installations include an X-server by default. For Windows hosts we recommend X-Win32 software by StarNet. It has been proved to work well with the ssh client mentioned above. X-Win32 is a licensed product; check if your university has a campus lincese. A large number of X server products for Windows can also be found in the public domain.


All the questions concerning the functionality described above should go to Kristoffer Rapacki, rapacki@cbs.dtu.dk. CBS will provide an opportunity to test the functionality around a week before the start of the course. The details will be announced later.
