The University campus network provides networking services to members of the University who access the network to support the academic, research and administrative activities of the University.
The user must use these services responsibly.
By connecting to the University campus network, the user agrees to the Campus Network Acceptable Use Policy, and related polices and regulations.
a. |
Do not assign your own
IP address |
|
An IP (Internet Protocol) address
identifies a computer within the campus network. Do
not attempt to assign your own IP address to your computer.
The IP address of a computer must be unique. Misconfiguration
of your computer may affect not only your computer but
also others on the network. |
|
|
When a PC is connected to the Hall
Network, ACEnet or Wireless LAN and is started up, the
PC should be configured to obtain an IP address assigned
automatically. This assignment is based on the ethernet
address of your network card. Thus, you must register
your network card beforehand. |
|
|
For PCs in department offices,
the IP addresses are assigned by the Computer Centre
when the PCs are set up or relocated. Departments are
required to submit the appropriate application form
to apply for additional IP addresses or when their PCs
are relocated. |
|
| b. |
Do not set up any servers like web servers,
ftp servers, file servers or DHCP servers |
|
Individual users are not allowed
to set up their own servers without permission from
the Computer Centre. These servers may cause excessive
network traffic. Besides, any improper server configuration
may lead to serious network problems. |
|
|
| |
Unauthorised DHCP service will
cause many campus network users unable to access the
campus network. If you are running Windows XP, make
sure that you do not enable the Internet Connection
Sharing (ICS) service which will automatically enable
DHCP service to assign IP addresses to other computers.
See the FAQ at http://www.itservices.hku.hk/faq/hallnet/Disable_ICS.htm
for details.
|
| c. |
Do not set up peer-to-peer file sharing programs |
| |
Peer-to-peer file sharing programs (like KaZaA, Morpheus,
BearShare, LimeWire, Grokster, Blubster, WinMX, BitTorrent (BT),
eDonkey,
etc.) can act like servers and generate a lot of network
traffic, thus slowing down the network and
affecting other users.
Moreover, they may distribute copyrighted material without authorization from the copyright owner. |
|
d. |
Do not connect additional
network hubs to the network |
|
Individual users must not connect
their own network hubs to the network points under the
HKU Network. Such an act is strictly prohibited as it
may affect the functioning and performance of the entire
campus network. Another reason is that the total number
of hubs connected to the network is limited, and exceeding
this limit may make the network inaccessible. |
| |
e. |
Do not power off or reset
network devices |
|
Various network devices are used
to link up the whole network. Resetting any network
device will cause interruptions of the network services
to the users and may even permanently damage the network
devices. If you suspect that there is a network equipment
failure, report it to the Computer Room of the
Computer Centre at 2859 2496. Do not reset any network
device yourself. |
|
f. |
Do not install broadcast protocols on your computer
|
|
Some users may wish to share their
computer resources (such as files and printers) with
other users by setting up Microsoft Network on their
PCs and installing the NetBEUI protocol or IPX protocol
on Windows platform. Since the NetBEUI and IPX protocol
are broadcast protocols, the installation of these protocols
will generate heavy network traffic in the entire network.
This will use up a large amount of network bandwidth
and degrade the network performance significantly, hence
affecting other users on the network. |
|
g. |
Use of Bandwidth
|
|
All use of the campus network, including hosting of web sites, should share the use of limited Internet and intranet bandwidth equitably. Computer Centre reserves the right to suspend a web site's network connectivity if it is found that the bandwidth it consumes is excessive in comparison with the total bandwidth available.
|
Failure to comply with the above
rules is considered to be a violation of the University's
Statement of Ethics on Computer Use and will lead to
suspension of access to the University's computer and
network services and possibly disciplinary actions.
