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
(choose the latest 'putty-xx-installer.exe' file for Intel x86). All PuTTY
software is freeware. Remember to enable X forwarding when defining your
- 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
All the questions concerning the functionality described above should go to
Kristoffer Rapacki, firstname.lastname@example.org.
CBS will provide an opportunity to test the functionality around a week
before the start of the course. The details will be announced later.
