Guidelines
for using the IT
infrastructure at the
Overview
In general, information on our IT
infrastructure is available at our web site http://www.cs.uni-bonn.de/dv .
Additional guidelines regarding the computer usage at the new building
(Neubau), particularly our computer pools, can be found at http://web.cs.uni-bonn.de/dv .
User
account
Principally your user account – or login – permits
access to all computers of our institute. Initially, your account is valid only
at the central computer pools, see below. For all other computers the
responsible divisions can activate your account if necessary. Attached to your
account is a unique number, your User ID or UID. On a Unix system this ID can
be obtained by using the command „id“. It is also the number printed on
your first identification card.
Access
control system
Your identification card (a card with a
magnetic stripe) allows you to enter the following computer pools:
·
Old
building (Altbau): A106, A227: Informatik III division
·
New
building (Neubau): N101: Informatik IV division
·
New
building (Neubau): N218, N222, N224: Central computer pools running Unix and Windows
Throughout weekdays you have access to rooms N 218, N 222, and N 224 between 8-21 o’clock. The admittance to all
other rooms can be granted to you individually. In order to get broader access
rights you must contact the divisions mentioned above.
Handling
your ID card
A card reader is mounted next to each door.
When pulling the identification card through the reading slot the information
stored on the card will be read and, depending on your access rights, the door
will open. Please enter the room swiftly and pay attention that no one
unauthorized comes along with you. You can leave the room at any time without
having to check out with your card. Normally the door should close
automatically, but please make sure that the door snaps completely.
Of course you must not give away your identification
card to anyone or enable unauthorized access to others. Needless to say the
card must not be duplicated or manipulated in order to gain additional access
rights. Please contact us immediately if you lose your card, damaged cards
should be returned. Lost or damaged cards will be replaced, charging you with 4
Euro. Please make sure the deposit on your print account is sufficient so that
the amount can be deducted.
References
to the protection of privacy
Your Unix User ID (UID) is printed on the
identification card. In addition to the UID the magnetic strip encompasses an
encrypted card number, a status field (assistant, student, guest) and the
expiration date. No other personal data is stored on the card.
By signing a delivery list when handing out the
card you allow us the inquiry and storing of personal data gained by using the
card. Every entrance is logged together with the card’s content described
above. These are stored only for a subsequent check of access permissions or in
case of a reasonable suspicion of abuse. Deletion will be carried out after an
appropriate period. As far as statistics will be generated they contain no
personal reference. You can revoke your acceptance to the storing of this data
at any time. In this case the card is to be returned.
The
entrance to the computer pools will be recorded with monitoring cameras.
Usage
conditions
By applying for a user account you have agreed
to the usage conditions of the
User data
Every user account owns a home directory which
is available on all computers (with the exception of certain divisons’
laboratories). On this central directory you can store data which will be saved
daily in backups and can be restored in case of emergency. Program-specific
configuration files are also located there. The available space is limited by a
quota. Additional information can be found at the institute’s web site as well.
Printing
and print accounting
The usage of
printers is charged, every printout will be deducted from an internal
print account. Payments to this account are only possible via wire transfer.
The wire transfer form can be printed at three PCs in room N223 using the login
name cash4lpr and entering your User ID. Alternatively, if you prefer
not to use this form please make sure that your wire transfer includes your
login name and your UID. Further information is available at the institute’s
web site at http://www.cs.uni-bonn.de/dv/pac/
. A scale of charges per printed page for each of our printers can be found
at the web page http://www.cs.uni-bonn.de/dv/pac/drucker-de.html .
Email
Along with your user account you receive a
personal email address specific to our institute to which all official notes
from the institute will be sent. It’s general form is loginname@cs.uni-bonn.de.
The institute’s mail service may only be used
by secure and authenticated connections, either locally or from computers
outside of the institute. Moreover, worldwide access to this mail service is
also possible via a web browser at https://webmail.cs.uni-bonn.de. Our web site contains far more
detailed information on this topic.
Remote
login and VPN
Remote login to the institute’s local computers
is only admitted indirectly by a secured connection (SSL) to the central login
server „login.cs.uni-bonn.de“. This can also be used to exchange data stored in
your home directory.
Furthermore you can get access by a VPN
(virtual private network). This requires a separate account. You will find
detailed information on this topic at http://web.cs.uni-bonn.de/DV/dienste/vpn/vpn.html

Wireless LAN is generally available but limited
to certain areas in the building. Access is only possible by secure connections
(IPsec) using the VPN infrastructure of our institute. Usage guidelines for
