Applying for HKU-Cert (digital certificate) through Intranet Systems for Staff and Students

Since the launch of the HKU-Cert * (digital certificates) issuing service by Computer Centre on 22nd September 2000, a HKU staff or student can get a HKU-Cert and the corresponding private key at the Centre's General Office (Room 223, Run Run Shaw Building).
* Note:  The HKU-Cert is issued through the HKU CA (Certification Authority) which is built on the Public Key Infrastructure (PKI) technology. 
Click here for a brief description of the basic mechanism of PKI.

Starting from January 2001, in order to facilitate our staff and students to apply for the HKU-Cert without coming to Computer Centre , users can apply for the HKU-Cert via the Intranet Systems for Staff and Students, respectively, as follows:

  1. Login the Intranet Systems
  2. After login, click the links "Computer Centre " and then "HKU-Cert On-line Application Form".  You will then be asked to enter a password for encrypting your HKU-Cert private key on a CD-R to be issued to you.
  3. You will be notified by e-mail to collect your Private-Key CD-R at Computer Centre General Office (Room 223, Run Run Shaw Building) . This process will normally take one working day.
  4. You can either go in person or ask a person authorized by you to collect your Private-Key CD-R.  At Computer Centre , you or the authorized person must show the appropriate personal identification (e.g. HKU Smart Card or HK Identity Card) and submit a signed copy of the HKU-Cert Subscriber Agreement (version 2.0).
Note 1:  When the applicant collects the Private Key in person at Computer Centre's General Office, he can at the same time request to save his private key to his HKU Smart Card.
Note 2: Since the password encrypting the private key is only known to the applicant, collection of the Private Key CD-R of an applicant by his authorized person would not compromise the security of his private key.

Use of the HKU-Cert

The HKU-Cert can be used in HKU Electronic Service Delivery (ESD) applications where electronic signatures are required, and in e-mail programs which support the use of electronic signatures and encryption of e-mail messages.

As more HKU ESD applications are being developed, users will find more occasions for using electronic signatures.  Apart from the on-line application form system and the Computer Centre Ordering System which were introduced in the previous issue of the Computer News, we are pleased to present another ESD applications using the electronic signature:

Should you have any enquiries relating to the HKU-Cert and its use for ESD (Electronic Service Delivery) applications, please contact the undersigned.

The Symposium on Fundamental Computing Education in Tertiary Institutes

On October 20, 2000, Computer Centre had organised, in association with the Association of Fundamental Computing Education in China (AFCEC), the "Symposium on Fundamental Computing Education in Tertiary Institutes" at the University of Hong Kong. The AFCEC, which was founded in 1984, is a National Association of China with the mission of fostering the development and advancement of fundamental computing education in tertiary institutions in China. The association has a membership of over 300 universities and colleges. Most of its members participate actively in the Steering Committee for the  Fundamental Computing of the State Education Commission and in the Committee on Grade Computer Examination of the National Education Examination Authority.

Both Professor Ian Davies, Vice Chancellor of HKU and Professor H Q Tan, President of the Council of AFCEC, who were guests of honour at the symposium, stressed in their speeches at the opening ceremony that information technology is of mandatory importance in today's society and the key to the future.  They also shared with the delegates at the symposium that the mission of university educators is to ensure that our students will master good techniques on IT, so that they could survive and thrive in the new e-economy world and contribute actively to the society.

The symposium was a valuable occasion for colleagues at HKU to share with more than 160 delegates from China and Hong Kong on the experiences and methodologies in teaching fundamental computing at the tertiary level.  The following keynote speeches were presented in the symposium:

From the Help Desk...the HKU ACEnet, Hallnet and VPN facilities

In the last issue, we looked at how to access the HKU network from home via the telephone lines using the PPP service. In this issue, we shall look at accessing the network from the residence halls (Hallnet),  the Access-Everywhere network (ACEnet), and accessing the HKU network from an ISP (Internet Service Provider)'s broadband service.

The Hallnet and ACEnet

In all the University's residence halls, network points are installed for every hall resident.  Students can plug in their desktop PC's or notebook computers to the network points in their rooms and connect directly to the HKU network.

In the ACEnet,  network points are installed on the walls in most major buildings in the university campus. Staff and students can use these ACEnet points for connecting to the network typically using a notebook computer.  Click here to find out the locations of these network points all through the campus.

The Network Interface Card

Before you plan to use the Hallnet or the ACEnet, you must obtain a Network Interface Card (NIC) for your computer. At present, all networking from PCs need the network card (except the PPP service which uses the modem as the network  interface).  The network card is what identifies your PC (with a machine number) to the network. Your network card has an ethernet address (EA) that is unique in the world.

You must register the EA of your network card with Computer Centre so that our network system recognises you as a legitimate user, otherwise the system will not allow access to those who did not register their network cards.  You can register your network card via the staff or student intranet.

When you connect to the Hallnet or the ACEnet, you will be assigned an IP address by the DHCP (Dynamic Host Configuration Protocol) server. The DHCP is the protocol that dynamically assigns IP addresses in the PPP dial-up system as well.

Your IP address is a unique number which identifies you on the Internet. If someone else is using the same IP address, then the browser will display an error message that there has been an IP address conflict and you will not be served the web page you requested.

If you wish to check the IP address you had been assigned by the DHCP, click Start...Run in your windows, then type the 'winipcfg' command in windows. If your IP address does not start with '147.8...' then it is wrong.  Be sure to select the correct network adaptor.  For hallnet and ACEnet, select the 'Ethernet adaptor', not the 'PPP adaptor'.  Then click the 'Release' and 'Renew' buttons at the bottom of the 'winipcfg' screen to release the last assignment and get a new IP address.

Moving in the Halls

For hallnet users, your name must be registered in the hall where you are staying before you can register your network card. Contact your hall manager about your hall registration if the intranet system will not allow you to register your network card properly.

If you had moved from one hall to another, you cannot use the network in the new hall. You must delete your previous network card registration in the student intranet system and then re-register it again under the new hall.

Broadband and VPN

More and more users are subscribing to the broadband service instead of using the PPP dial-up service for faster speed on the Internet.  Broadband refers to telecommunication that provides multiple channels of data over a single communications medium typically using your cable TV line (with higher bandwidth) instead of the telephone line.

When you use the broadband service, you are subscribing to an ISP.  When you connect to the HKU network from an ISP, you can only view contents placed on the HKU web server ( but not contents on the intranet such as the Student Connect system, the UIS system etc.

To access systems installed on the HKU intranet using an ISP's network service, you must use our VPN service. The VPN connection makes use of the Internet's routing infrastructure to move secure data to and from a private network, maintaining privacy through the use of a tunneling protocol and security procedures. The details for configuring the VPN server and procedures for connecting to the HKU network can be found at

Currently, only Windows 95/98 operating systems are supported but not Windows 2000.  The equipment manufacturer for our VPN gateway decided to quit from the enterprise network market, and hence, there will not be any upgrade for our existing VPN gateway.  However,  it is our plan for the next development of the VPN service to support the Windows 2000 and hopefully other platforms as well.

The proxy server

A proxy server serves as a gateway for the security of the institution. It also serves as cache memory space for storing webpages.  If you request a webpage from an external site outside of HKU, the browser will first look for the page on the proxy server.  If it finds the page, it returns it to the user without searching on the Internet. If the page is not in the cache, the proxy server, acting as a client on behalf of the user, uses one of its own IP addresses to request the page from the server out on the Internet. When the page is returned, the proxy server relates it to the original request and forwards it on to the user.

When using the Hallnet, the ACEnet or the VPN networks, you must configure the proxy server in your browser or you will not be able to view sites outside of HKU.  As the proxy server may be moved to different hardware from time to time, you should configure for the automatic proxy. The automatic server location is at

WebDAV - a Software Tool for Easy Updating of E-Courses on WebCT server 

Our WebCT users may find uploading webpage files to the WebCT server not an easy task because it involves multiple steps.  We are pleased to inform our users that we have recently installed WebDAV on the HKU WebCT server ( which should simplify the tasks of uploading and managing the course files in the WebCT server.

What is WebDAV?

WebDAV stands for 'Web-based Distributed Authoring and Versioning'. It allows web authors to manage files of their web sites through the 'Web Folders' of their local workstation operating on Windows or Macintosh. With WebDAV, course designers can now manage files of their WebCT courses directly on remote web servers from their workstations without having to upload and unzip files via the browser interface.

How to make use of WebDAV?

Follow the procedures listed below to set up WebDAV and web folders on your PC or Macintosh. The web folders created for your WebCT courses on the server can then be referenced as if they are on your local disk drives.

Notes on using WebDAV

  1. WebDAV supports file locking so that when a user is editing a file in a web folder, that file can only be viewed on the web but cannot be edited by other users.
  2. Although multiple web folders can be defined, only one folder (connection) can be active at a time. e.g. If a designer owns 2 WebCT courses and sets up 2 web folders for these courses, he has to enter his designer account name and password every time he switches from one folder to the other. Therefore, it is preferred to work on one folder at a time.
  3. For applications such as Office 2000, the web folder icon will appear in the folder list of the application such that users can edit the file directly from this application. For other applications in which the web folder cannot be located, users can save their files on a local disk drive and then copy the files to the web folders later.
Setting up WebDAV for users of Windows95 or above

The pre-requisite is to have the IE5 browser installed. Then, follow these steps to setup a web folder that connects to your WebCT course :

  1. Start 'Window Explorer'
  2. Click 'Web Folders'
  3. Click 'Add new web folder'
  4. Enter '' as the location, e.g.

  5. Enter your WebCT designer's name and password

  6. Label the new web folder with an identifier of your choice, e.g. 'Introduction to WebCT'

  7. This folder can now be referenced by Windows
Setting up WebDAV for users of MacOS 8.1 or above

System requirement for Mac users is to have a PowerPC based Macintosh running MacOS 8.1 or higher. Follow these steps to connect to your WebCT course through WebDAV:

  1. Download the Goliath application at and install it in your Mac
  2. Start WebDAV and make a new WebDAV connection to your WebCT course

  3. To upload files to server, drag-and-drop the files to the WebDAV folder

To learn more about WebDAV on Mac, please visit this web site

If you would like to learn more about WebDAV, please visit their site at If you have any further questions, please contact the undersigned.

The HKU Gigabit Ethernet Campus Network Backbone

The HKU campus network backbone has been using the ATM (Asynchronous Transfer Mode) technology since 1997 to provide a faster network and to implement the ACEnet roaming network.

As the vendor supplying our existing ATM network equipment is backing out of the highly competitive network equipment market and is phasing out the customer support, Computer Centre has to resort to other network equipment providers in order that we get the most cost-effective supplier and support for our network.  In the past few months, Computer Centre was searching for a substitution solution that can meet our network backbone requirements.

The Gigabit Ethernet (G.E.) technology is found to be one of the best solutions available as its price has dropped drastically and it would meet the large bandwidth requirement of our current campus network. Besides the bandwidth requirement, inter-operability with existing network equipment is also a major factor to consider. The Virtual Local Area Network (VLAN) technology is being used in the existing ATM campus backbone to facilitate the linking together of geographically dispersed users. Now the Ethernet-based VLAN technology has become mature enough to be deployed. With all these advantages, the G.E.-based network infrastructure was selected to inter-operate with our ATM-based campus network.

Two high-density G.E. backbone switches had been installed in October serving as the new G.E. backbone.  These two G.E. backbone switches have a very compact design that each switch can provide integrated functions of router, ATM switch and G.E./F.E. switch within a single box. The router function provides additional network traffic routing capacity to the existing network, so that the existing backbone routers can be off-loaded and network resiliency is increased. The ATM switch function provides connectivity to the existing ATM backbone and thus the two backbone networks can be linked up. For the G.E. switch itself, it can be configured to use VLAN-based network topology to join the existing VLAN-based ATM network. Therefore the overall new backbone can be fully inter-operable with the existing network. We have already performed many tests with positive results before actual implementation.

The entire implementation plan has different phases and we are working with the vendor closely. At the current phase, the two G.E. backbone switches were installed and running.  One of the switches is installed in Computer Centre and the other is in the Kadoorie Biological Sciences Building as a backup. The new G.E. backbone switches are connected to each other by two G.E. links with load-sharing function enabled. Each G.E. backbone switch has a ATM OC-12 (622Mbps) link to connect to the existing ATM backbone network. In this backbone design, there should be no single-point-of-failure between the backbone switches. Several network segments had been switched over to the new backbone and they are running normally without any problems.  Some network traffic on the old backbone had been re-routed to the new backbone to off-load the old backbone routers.

In the next phase, we are going to install 15 to 20 high-density F.E. switches with dual G.E. fiber uplinks to different buildings to serve as a building concentration switch for that building. To cope with the increased need of fiber connections between building in the main campus, additional fibers are being installed. We shall report further on the progress of the GE backbone upgrade project as it develops.


Asynchronous Transfer Mode

ATM (asynchronous transfer mode) is a dedicated-connection switching technology that organizes digital data into 53-byte cell units and transmits them over a physical medium using digital signal technology. Individually, a cell is processed asynchronous relative to other related cells and is queued before being multiplexed over the transmission path. Multiplexing is sending multiple signals of information on a carrier at the same time in the form of a single, complex signal and then recovering the separate signals at the receiving end. Our ATM backbone has a transmission speed of 622 Mbps.

Gigabit Ethernet

Gigabit Ethernet (GE) is a local area network transmission standard that provides a data rate of 1 billion bits per second (one gigabit). Existing Ethernet LANs with 10 and 100 Mbps cards can feed into a Gigabit Ethernet backbone.

Fast Ethernet

Fast Ethernet is a local area network transmission standard that provides a data rate of 100 megabits per second (100BASE-T). Workstations with existing 10 megabit per second (10BASE-T) ethernet cards can be connected to a Fast Ethernet network.

virtual LAN

A virtual LAN is a local area network with a definition that maps workstations on some other basis than geographic location (for example, by department, type of user, or primary application). The virtual LAN controller can change or add workstations and manage load balancing and bandwidth allocation more easily than with a physical LAN.


Ethernet is the most widely-installed local area network (LAN) technology. A local area network (LAN) is a group of computers that share a common communications line and the resources of a single processor or server within a small geographic area (e.g. within an office building).  An Ethernet LAN typically uses coaxial cable or special grades of twisted pair wires providing transmission speeds up to 10 Mbps (10BASE-T).

Upgrade of the WAN Links to University Hall and Ricci Hall

We are pleased to announced that the WAN (wide area network) links to the student residences University Hall and Ricci Hall have been upgraded from 256Kbps to T1speed  (1.5Mbps) since December 1, 2000. The network traffic congestion problem previously experienced by residents of these two halls is now resolved and the network access response is much improved.

At the moment, Computer Centre is also in the process of installing additional fibre cables and routers for serving the student residence halls in the Sassoon Road area, namely the Lee Hysan Hall, R.C. Lee Hall,, Wei Lun Hall and the Madam S.H. Ho Residence for Medical Students, so as to alleviate the network traffic congestion problem which could occur during the peak usage period at night time.  This development is scheduled to be completed by February 2001.

Should you have any questions relating to the network improvement work for the halls mentioned above, please contact the undersigned.

Upgrade of the HARNET-CERNET Connection and Development of the HARNET-Internet2 Connection

Upgrade of the HARNET-CERNET Connection

We are pleased to announced that the dedicated network link for connecting HARNET (Hong Kong Academic and Research Network) and CERNET (China Education and Research Network) has been upgraded to an E1 (2.048 Mbps) IPLC (International Private Leased Circuit) since December 1, 2000. Before the upgrade, the link between HARNET and CERNET was only supported by a 64Kbps connection. The upgraded link is now connected directly to the HARNET router which provides a shorter route for Internet communications between all local universities and the institutions in China. Since the upgrade, the response of accessing network sites of  CERNET has been noticeably improved although we can notice that the utilization of the upgraded links has already become very full.

Development of the HARNET-Internet2 Connection

In Issue No. 86 of the Computer News, we reported that Computer Centre has embarked on a development together with the JUCC (Joint Universities Computer Centre) to provide  Internet2 connectivity for HARNET so that this forefront network facility could be available to our users.

The aim of Internet2 is to develop advanced Internet technology and applications for the research needs of higher education.  Over 180 U.S. universities, in cooperation with industry and government, are leading the project. Internet2 will provide better and more powerful network capabilities to support the research and educational activities of universities and research institutions. Internet2 is capable of three things: higher bandwidth; multicasting; and guaranteed delivery and performance. However, Internet2 is not just a faster network, it is also a testing ground for participating members to experiment with Internet applications of the future using various new and emerging Internet technologies.

In September, 2000, the JUCC signed a Memorandum of Understanding (MOU) with the University Corporation for Advanced Internet Development (UCAID) in U.S.A. to be an International MOU Partner of Internet2, together with a Joint Agreement for Interconnection of HARNET to the Abilene Network of Internet2.

The Abilene Network is the major backbone network connecting Internet2 sites and universities in the North America. There are many data exchange points along the Abilene Network. The most common access point for Asian network connections is the Science, Technology and Research Transit Access Point (STAR TAP) where many Asian networks (e.g. CERNET, SingAREN, TANET) connect to. The STAR TAP is essentially a large ATM switch in Chicago with enough capacity to provide stable configurations of emerging network technology, plus the network engineering to provide new services to an ever-expanding international community. For further details on Abilene Network, interested readers may consult the following links:

The Abilene Project:
About Abilene:

It is the plan of JUCC to connect HARNET to the Internet2/Abilene Network through a direct network connection of 10 Mbps or higher to STAR TAP in year 2001.  At present, the JUCC is also in the process of soliciting industrial and commercial sponsorship to facilitate the set up of the HARNET-Internet2 connection. Users who are interested in knowing more about the HARNET-Internet2 development can contact the undersigned for more information.

Mathematica 4.0 and SPSS 6.14 installed on HKUSUA

We are pleased to announce that Mathematica 4.0 and SPSS 6.14 for Unix have recently been installed on the HKUSUA system. The use of these two software packages are discussed in the following:

Mathematica 4.0

Mathematica is a software which lets you perform highly complex numerical, symbolic and algebraic computations easily and displays the results with sophisticated graphical plots to output devices and files.

1. Functions and features

Mathematica has over 843 built-in functions for numerical and symbolic calculations, processing and plotting of  2D and 3D graphics, as well as for users to create their own libraries for the specific needs. Mathematica also provides interfaces for linking external software e.g. TEX or user programs written in C or Fortran. Thus, within a processing session using Mathematica, you can pass information to or receive information from other applications and programs.

Note: Mathematica is made of two parts: a kernel and a front end. The kernel is the part which does calculations while the front end is the part which handles Mathematica notebook files and interacts with the user.

SPSS Release 6.14 for Unix

SPSS is an integrated and comprehensive system for statistical data analysis.  Due to the phasing out of the HKURSC system on which the SPSS package was previously installed, SPSS for Unix (Release 6.13) has been installed on HKUSUA since October,  2000.  The SPSS modules available on HKUSUA include:
SPSS Base provides you with the basic functions of data access, data preparation, analytical reporting and predictive modeling so that you can analyse the data you have got for making better decisions.
SPSS Tables provides you with the functon to generate reports in tables format from results of analyses which could be very complicated. The tablulated results would enable you to communicate your  results with others effectively.
SPSS Categories can be used to predict categorical outcome when you understand how items are grouped with perceptual maps.
To invoke SPSS on HKUSUA, go through the following steps (as in the previous HKURSC system):
  1. Start the Excursion program on your PC or type &ldquo;xhost +&rdquo; on your workstation.
  1. Login to and type the command
&lsquo;setenv DISPLAY your_ip_address:0.0&rsquo;
to setyour display environment to your PC or workstation.
  1. Type &lsquo;spss&rsquo; to invoke the SPSS package.
  2. To run SPSS in batch mode (No Graphical User Interface), please use the following command
                                   spss -m <  input_fileanme > output_filename
If you encounter any problems in using SPSS, please report them by email to or

Should you have any enquiries related to the the procedure in using the SPSS software, please contact the undersigned.
