GENERAL NEWS


What's new in Computer Centre

To all staff and students of the University, whether they are old or new, I would like to take this opportunity to keep them informed of our latest development and to highlight some significant services that Computer Centre has introduced in the last few months.

Location

Computer Centre is primarily located on the first and second floors of the Run Run Shaw Building. We also have offices located in the Dental Hospital, the Old Library Building and the Eliot Hall. Other than the open space on the first floor which are equipped with PCs and Macintosh, various microcomputer laboratories have also been set up in the vicinity and in different buildings of the University including the Knowles Building, Main Building, K K Leung building, composite Building and buildings in the Medical and Dental campuses as well as the Student Amenities Centre.

New Microcomputer Facilities

In September 1996, a newly renovated Microcomputer Laboratory in Room 201 of Run Run Shaw Building with video projection for teaching purposes has been put into services. This laboratory is equipped with 25 Pentium PCs and all of them are installed with sound cards running multimedia applications. Besides, 10 new Power Macintosh 7600 systems have been acquired and set up in Room 104, Run Run Shaw Building to better cater for the need of the Macintosh users. The 10 Power Macintosh 8500 systems originally installed in this laboratory were moved to Room LG 108 of K K Leung Building which is now equipped with 16 Macintosh units.

User Services

Computer Centre offers a comprehensive Computer Centre to staff and students of the University. Both the network and central computer facilities have been enhanced in the past year to meet with the demand of increasing number of users and advanced technology requirement.

To provide our users with the necessary skills to use our facilities, we offer regular training courses on all our computer facilities and on various kinds of software, electronic mail, access to Internet, World Wide Web (WWW), news bulletin service and multi-media facilities etc. All these training courses and workshops are well received by our users. So book your seat early to avoid disappointment.

We also maintain a library of computer periodicals, reference manuals and books which are available for short term loan from our General Office in Room 223 of Run Run Shaw Building. The size of this library continues to grow as the variety of our services keeps expanding. Some popular manuals are now placed in the Reserve Book Room of the University's Main Library to facilitate the use by staff and students of the University.

As in the past, Computer Centre continues to arrange site licensing of many PC software as well as bulk purchasing agreement on PC hardware and software from vendors, many of which are operated through the auspices of Joint Universities Computer Centre (JUCC). Users are welcome to enquire on these low cost hardware/software arrangements from our General Office or through the "Campus Wide Information Services" through the campus network.

In addition to our regular assistance to our users through the Help Desk services being provided in Room 109 of Run Run Shaw Building, users can also send their enquiries and feedback to our electronic account "ccbox@cc.hku.hk" and the newsgroup "hku.cc.forum". Many valuable advice and comments have been received through these channels and we strive to improve our services wherever possible.

New Central Computer Services

In the last year, we have acquired two powerful central computer servers to enhance the central computer services of the University as a whole.

A SUN UltraSPARC Enterprise 6000 system with 8 processors, 512MB of memory and 16GB of disk storage has been acquired to replace the aged HKUXA and HKUXB Digital ULTRIX systems and to augment Centre's existing academic computing systems which are serving over 12,000 students and staff users. This system has been put into services since October 1996. This system is named as HKUSUB and is accessible from the campus network by all University members. We plan to phase out the HKUXA and HKUXB systems in the coming summer.

Another UltraSPARC Enterprise 6000 system with 8 processors, 384MB of memory, 16GB of disk storage with software "First Watch" installed was acquired to integrate with the existing Information Server which is a SPARCcentre 2000E to provide resilience to the University's various Internet services, such as WWW, USENET News, email, ftp etc. This integration work to form a High-Availability Information Server is underway and is expected to be operational soon.

Two Clariion RAID disk subsystems each with 20GB of disk storage were also installed to provide additional disk storage for the academic and information servers. The addition of disk storage on the academic server enables the increase of default user disk quota allocated by 1MB which can ease the difficulties of many users who are finding their present disk space allocation inadequate. Increase in the disk storage on the information server can better cope with the increasing needs of departments to disseminate information over the Internet WWW and the University's Intranet.

To support certain parallel applications to run more efficiently on the IBM SP2 supercomputer, an addition of four 64MB of memory and four 2 GB disks have been acquired to increase the memory and local disk of 4 of the 32 processors from 64MB to 128MB and from 2GB to 4GB respectively which is scheduled to be done early next year.

At present, telnet access from Internet outside the University campus to the central UNIX hosts is generally prohibited. To relax this inconvenient restriction while an acceptable level of network protection can be maintained for over 12,000 user accounts on our system, a Sun Solstice Firewall-1 system has been acquired which is now under installation and testing. It is planned for operation in January 1997 and selected telnet access to our host computers from outside the University campus will then be implemented through the network firewall gateway.

All our servers and network operates 24 hours a day, 7 days a week. They are however running unattended on all Sundays and public holidays. If you are not yet one of our users, you will need to apply for a computer account on one of our servers. There is an automated procedure for registering a user account, which once created will be valid until you leave the University.

Network Connections to the Campus Network

Our work on the campus network which started in 1988 has been extended to cover basically all buildings in the campus. Over the years, the network has been expanding continuously as more and more users are gaining access to our network. Several enhancements on network connectivity has been made in the last year.

The network communications speed between the main campus and the Medical and Dental campuses, the Wide Area Network (WAN) links to Patrick Mansion Building in the Sassoon Road area, the QMH compound and the Prince Philip Dental Hospital were upgraded from 512Kbps to T1 (1.544 Kbps) speed in July 1996. Besides, new fibre-optics cables were laid to link Tang Chi Ngong Building, Tsui Tsin Tong Building and Lindsay Ride Sports Centre to main campus in mid-1996 with Ethernet hubs installed. The enhancement work of the network backbone bandwidth for Runme Shaw Building, Hui Oi Chow Building and James Lee Building was also completed in November 1996.

Work for providing network PC facilities in the four student halls on Sassoon Road, namely Wei Lun Hall, Lee Hysan Hall, R C Lee Hall and the Madam S H Ho Residence for Medical Students is in progress. These buildings are now being connected together through fibre-optics cables, with UTP connections to the PCs. A PC room with a few networked-PCs will be set up in each of these halls for students' use. Network connections are also provided in the offices of the Hall Manager and the Warden. A Novell Netware PC-Server will be set up to provide the necessary software for campus network connectivity in these halls, connected by a 128Kbps leased circuit to Computer Centre . All the equipment has been delivered and the facilities can be set up as soon as the cabling work by the contractor and the installation of the leased data line by Hong Kong Telecom is completed.

A new LAN PC-server has been set up for the Meng Wah Complex and users in the complex are being migrated to use this new server. Besides, the LAN servers supporting the academic departments in Runme Shaw Building, K K Leung Building, Knowles Building , Haking Wong Building, Main Building, Patrick Mansion Building, Queen Mary Hospital and Prince Philip Dental Hospital were successively upgraded to Pentium systems in the period from December 1995 to November 1996. The network operating systems of all these servers were also upgraded to Novell Version 4.1.

Computer Centre has also helped the Main Library to upgrade its network to use Fast-Ethernet and switched Ethernet technology. A Fast-Ethernet-to-FDDI router for connecting the upgraded Library network to the FDDI Campus Network backbone was installed.

We have started to pilot test the ATM and virtual LAN technologies. A pilot ATM network with 10BaseT Ethernet connections has been successfully set up and put to test in Computer Centre's PC LAN facilities in the Old Library Building and in the Run Run Shaw Building in October 1996. Virtual LAN (VLAN) over ATM which can allow PCs located in different locations on the campus network to form a single LAN using the same group of network addresses, were also under pilot-testing. This functionally is particularly useful for connecting PCs to the network in classrooms and for departments having offices in different buildings. This ATM pilot network is known to be the first deployment of VLAN among JUCC institutions.

Dial-up Services

To cope with the extremely high demand of HKUPPP dial-up services for home access to the University's network by staff and student users, a total of 60 high-speed (28.8 Kbps) dial-up modems and terminal servers ports have been installed in the past year. Thirty lines are reserved for the use of staff. The other thirty are accessible by both staff and students with ten 24-hour service lines and twenty night-service lines. More dial-up lines will be made available for the use by the staff and students in early 1997 to meet with the increasing demand of dial-up access to the campus network.

Upgrade HARNET and Internet Links

Our University is connected to the other seven tertiary institutions via HARNET (The Hong Kong Academic and Research Network) which is in the process of being upgraded from T1-Internet link (1.544 Mbps) to E1 speed circuit (2.048 Mbps) in January 1997 through our working with the Joint Universities Computer Centre (JUCC). This will provide a 30% increase in bandwidth and relieve the current Internet traffic congestion so that the access to Internet can be improved.

New Developments

Computer Centre has continued the study and development of electronic forms and their wider use within the University. This year we have embarked on developing electronic forms using the WWW user-interface, direct database integration and authentication for different user access privileges. A new generation of electronic forms, accessible through all system platforms supporting WWW, was developed for host computer account and HKUPPP account applications, HKUPPP usage status enquiry and HKU Communication Directory enquiry. An electronic form and workflow control system for the central administrative offices to initiate their job requests to Computer Centre is being developed.

The use of electronic forms integrated with other automated processes has proved to increase the efficiency of work significantly, such as the deployment of host computer and HKUPPP account electronic forms has shortened the creation time of such user accounts from seven days to one day.

The pilot ATM/Fast-Ethernet experimentation will contribute to the use of video conferencing and video on demand on a larger scale over the campus network. The video and audio conferencing over the campus network using low cost PC based hardware and the enhanced CU-seeme and Cooltalk software, and distribution of compressed video and audio information through the web-based interface have been evaluated and tested. It is expected that the technologies and performance of these applications will be getting more mature and the demand of video conferencing and multimedia transmission over the campus network will grow very quickly.

A WWW proxy server was put into services in November 1995 which helps to reduce the demand on the bandwidth to our Internet links, as it caches frequently accessed web pages around the world. The cache hit ratio is at about 50% i.e. about half of the web page access can be retrieved from the proxy server, instead of going to the various web sites. Another WWW proxy server is also being set up in Sassoon Road area.

New User Guides and User Services Handbooks

To assist our users in using the Centre's services and facilities, new publications of our User Guides and User Services Handbooks will be available in early January 1997 to provide the latest and basic information to enable our users to start using our facilities which include Computing Services Handbook, Unix Users Guide, Network Services Guide for Unix Users, VMS Users Guide and Network Services Guide. These publications can be purchased at nominal cost from our General Office.

Computer News

The Computer News is one of our means of communication with our users. This newsletter was published both on our web page and on paper before. From this issue onwards, no printed paper copies will be distributed and you can keep abreast of our Centre's news via Computer Centre's web page (http://www.its.hku.hk/news/).

In this article, I have tried to summarize the many new developments that we have achieved in the past year. It is by no means a complete account of what we have done. You will have to read other articles to find more details of our services being provided. I hope you will enjoy reading this newsletter and find the information useful to you. Your feedback and comments are always welcome.

Lastly, I would like to take this opportunity to wish you and your family a Merry Christmas and a Happy New Year.

Computing Services Survey

As a commitment to the improvement of services provided by Computer Centre to the HKU community, a quality assurance (QA) programme is underway in Computer Centre .

The objectives of the QA program are to better understand the needs and expectations of our users for services provided by the Centre, and to ensure the Centre's service can meet the specified levels of quality.

The essence of quality assurance can be summarised as follows:
- to communicate with users in determining which service attributes are most important,
- to measure and determine how Computer Centre is performing against those attributes set,
- to continuously improve Computer Centre service to best meet its users' requirements, and
- to implement quality control within Computer Centre to ensure "conformance to specifications".

In the coming months, we will be communicating with our users in the form of interviews, questionnaires and surveys etc. to determine what service attributes are the most important, and to determine where we stand for present service quality levels.

As part of our QA programme, Computer Centre will conduct a survey to find out the users' opinion about the Centre's computing facilities and services. The results of the survey will help us to review and improve our existing services and to formulate future development plans. The questionnaire for the survey will be sent to all University members who are on the "Computer News" distribution list by end of December, 1996. To ensure our survey reaches every University members and to hear the opinions from as many University members as possible, we have also placed the questionnaire of the survey in the Centre's web page. University members, if they prefer, can fill in the survey questionnaire electronically by selecting the "Computing Services Survey" questionnaire under Computer Centre's entry via the URL http://hkusua.hku.hk:8111/ccform/owa/computing.survey . We hope to have the full support of the University members and all completed survey questionnaires could be returned to us by January 15, 1997.

Since QA is a mutual affair, let us keep our dialogue closely together for the betterment of the central computing facilities and network services of the University.

If you have any questions or suggestions regarding the facilities and services provided by Computer Centre , please feel free to contact the undersigned.

New default disk quota

To cope with the increasing use of the Internet and network services, e.g. e-mail, and resulting higher demand for more disk storage to hold the data, we have recently install a 20GB RAID subsystem to increase the disk storage on the HKUSUA system and 6GB of disk storage on HKUCC system. With this development, we can increase our default disk quota for new accounts by 1MB effective from January 1, 1997. Hence the new default disk quota allocation on HKUSUA and HKUCC systems will be 6MB for staff and postgraduate students and 4MB for undergraduate student starting from 1997. For accounts created before 1997, the users' old default disk quota will also be automatically increased to the same new level of allocation.

Phase-out plan for HKUXA/HKUXB and DECstation workstations

The hkuxa and hkuxb systems (DECsystem 5500) are the oldest UNIX servers in Computer Centre . A cluster of DECstation 5000/125 workstations, most of which are set up in room RR-210, are also connected to the hkuxa and hkuxb servers. With the fast advances of computer development, Computer Centre has installed a number of new and more powerful UNIX systems, e.g. hkusua, hkusub, hkursc, hkusga etc., in recent years; and many users have already changed to work on these more powerful and faster systems. The usage of the hkuxa and hkuxb servers and the DECstation 5000/125 is now relatively low.

In view of the fact that all the essential user applications now running on hkuxa, hkuxb and the DECstations, such as email, tin, hytelnet, etc., are provided on Centre's other faster UNIX servers and that the maintenance of these aged systems is no longer economical, we are planning to retire these computers in 1997.

As the first step, 10 DECstation 5000/125 in Room RR-210 has been replaced by new Sun SPARCstation4 systems and two DECstation 5000/125 in Room RR-107 will soon be removed. Meanwhile, only 4 DECstations in room RR-210 will continue their service.

To facilitate our users to migrate their applications from hkuxa/hkuxb to other systems, we shall, in January 1977, set up accounts on the hkusua/hkusub/hkursc/hkusga UNIX server cluster with the same username and password as those of the hkuxa/hkuxb servers for those who do not have accounts on the hkusua/hkusub/hkursc/hkusga UNIX server cluster. Our staff will provide the necessary assistance to the users in their application migration and working in the new system environment.

Our next step is to stop all login access to the hkuxa and hkuxb systems at the end of April 1997. Users are thus advised to start changing to work on hkusua/hkusub/hkursc/hkusga cluster as soon as possible so as to avoid inconvenience due to unavailability of the hkuxa and hkuxb systems.

Users who have any concerns and queries about the above described arrangements, please contact the undersigned immediately.

High-resilient Central Information Server

We are pleased to announce that the integration of Centre's Sun SPARCcenter 2000E
(HKUSUC) and the Sun UltraSPARC 6000 (HKUSUD) to form a high-resilient
Central Information Server as reported in the last issue of Computer News has been
completed. In this development, we have gone through the stages of configuring the
2 Sun SPARC systems with dual network attachment and the installation of shared
SSA (Sparc Storage Array) system as well as the systems and application software.

One point we would like to make clear is that high-resilient is different from
fault-tolerant or non-stop system. The high-resilient Central Information Server can
be viewed as a system as shown in the following diagram:



The two computers are both connected to the campus network and share a commonly accessible SSA subsystem. They also communicate with each other through a separate network connection dedicated for mutual system status monitoring. When one of the computers fails, its functions will then be started automatically on the other computer. While all the jobs and processes running on the failed computer will fail together with the computer, the system functions on the failed computer can be recovered and become available on the other computer as soon as the failure of the computer is detected. Thus service interruption due to system failure as well as system hardware and software upgrading could be minimised.

With the installation of the high-resilient Central Information Server, we expect that the availability of the Internet services on the Central Information Server will be greatly improved.

An easy way to measure the access frequency of a web page

Computer Centre is pleased to announce that we have made available a program for adding an access counter for a web page on the HKU WWW Server. If an administrator of a web page wishes to count the number of visits (accesses) to the web page, from now on, he can simply add a digital counter for such purpose to the web page by inserting the following HTML statement in the appropriate place of the web page file:
<img src="http://www.hku.hk/cgi-bin/Counter/Count.cgi?df=accountName-pageFileName">
where accountName is the web page administrator's account name on the HKU WWW Server (i.e. www.hku.hk), and pageFileName is a name to identify the web page having an access counter shown.

For example, if you are a web page administrator with account "xxxx" and you want to add a counter to the web page "index.html", you can simply add the following statement to your index.html file:
<img src="http://www.hku.hk/cgi-bin/Counter/Count.cgi?df=xxxx-index.html>
A digital counter like the following will be shown to the user when he visits this web page. The value shown will be increased by one for each visit to the web page.



The following options can be used to change the style of the digital counter,
e.g. font type, frame size, frame color, etc.

Format of option

Meaning of option

Possible values

dd=type Type of Digital Display A, B, C, D or E
(see the example below)
ft=number Frame Thickness An integer number
frgb=number;number;number Frame Colour - defined by three numbers separated by ";" showing the intensity of Red, Green and Blue respectively number=0 to 255


Note that these options can be separated by the character " & ", and there must be no space around the character "&".

For example, the following HTML lines in the web page file will show different digital counters. Note that the third counter has a purple frame (specified by "frgb=127;0;127"), and the seventh counter has a black frame as the background (specified by "frgb=0;0;0").

Netscape Proxy Server 2.5 available on www.hku.hk and HKUMD1

A WWW proxy server is a program that a web browser can communicate with to check whether a web page can be downloaded from the nearby proxy server, instead of directly downloading from the remote web site. The caching of web pages by a proxy server will usually speed up the download. In November 1995, we have installed version 1 of the Netscape Proxy Server on the HKU WWW Server, www.hku.hk. About 50% of the requests of web pages can be found in the cache of the proxy server. This has helped us to reduce our usage of the JUCC global T1 link, which is shared by the JUCC institutions.

We are pleased to announce that version 2.5 of the Proxy server, which has been released recently, is installed on the computer proxy.hku.hk in Computer Centre and the computer hkumd1.hku.hk in the Sassoon Road campus. Version 2.5 of the Proxy Server fixes some of the bugs of version 1.

The user can configure the Netscape browser run on his computer to use the Proxy Server as follows:

1. Double click on the Netscape browser icon. The Netscape window will appear.

2. For version 3.0 (or above) of Netscape browser, from the top menu bar, select the menu 'Options', then 'Network Preferences'. When the window "Preferences" appears, click on the tab "Proxies". Select the choice "Manual Proxy Configuration", and click on the "View" button. The window "Manual Proxy Configuration" will appear.

For version 1.1 of Netscape browser, from the top menu bar, select the menu 'Options', then 'Preferences'. When the window "Preferences" appears, click on the choice-list "Set Preferences On" and choose the item "Proxies". The fields for setting the proxy values in the window "Preferences" will appear.

3. For users in the buildings not in the Sassoon Road campus, fill in the values for the following fields:

Netscape News Server 2.0 and tin 1.3 available

We are pleased to announce that we have recently upgraded our Netscape News Server software from version 1.1 to version 2.0 and run it on a more powerful machine, Sun Ultrasparc Enterprise 6000E system (i.e. news.hku.hk). This version of News server has serveal new features, e.g. nov (news overview) style index files and multi-threading client servers for fast connection.

In addition, the disk storage required for holding the newsgroup articles of the News Server has been increased to 11G so that the expiry period of all newsgroup articles is increased to 7 days.

In tandem with the upgrade of the News Server, we have also upgraded the News client program, tin, on centre's UNIX machines to version 1.3. This new version of tin will automatically utilize the nov (news overview) style index files if they are available locally or via the nntp xover command. In addition, the new version of tin can support switching between news servers.

Like its previous version, tin has four separate levels of operation: Group selection level, Group level, Thread level and Article level. Each level has its own set of commands. Users may use the 'h' (help) command to view a list of the commands available at a particular level.

Should users encounter any problems in using the upgraded News system and tin program, please contact the undersigned for assistance.
