General News

Welcome to Information Technology Services

This is the beginning of another academic year. I take this opportunity to welcome all new staff and students to the campus and to introduce the services and facilities that are available in Information Technology Services. I would also like to keep users informed of the exciting new services that we have introduced this summer, some of them being described in detail in other sections of this Newsletter.

Location

Information Technology Services is primarily located on the first and second floors of the Run Run Shaw Building. Other than the open space equipped with Pcs and Macintosh, we have microcomputer laboratories set up in the vicinity as well as in the different buildings of the University, including Knowles Building, Main Building, K K Leung Building, Runme Shaw Building, Composite Building, buildings in the Medical and Dental campuses as well as the Student Amenities Centres. We are also expecting additional space for laboratories in the old Library Building, due for completion later in the year.

Services Provided

Information Technology Services offers a comprehensive computing service to all staff and students of the University. Services include time-sharing and batch processing of computer jobs, training courses on the usage of the Centre's facilities and some popular PC software, electronic mail, access to the Internet, bulletin board services and multi-media facilities.

We maintain a library of computer periodicals, reference manuals and books, which are available for short-term loan from our General Office located in Room 223, Run Run Shaw Building. Some popular manuals are also placed in the Reserve Book Room of the University's Main Library.

A Help Desk service is available to provide consultancy to our users. Its main purposes are to direct users to relevant information, to guide inexperienced programmers and to give suggestions on solving programming problems. The Help Desk is located in Room 109, Run Run Shaw Building One of our staff is on duty during office hours to answer queries from our users.

We have set up a channel of communication with our users by electronic messages. A user account called CCBOX is set up in all our host systems Users are welcome to send messages to this CCBOX account to make enquiries on the Centre's facilities, to give suggestions or comments on our services provided and to report any hardware failure.

Time-shared Computer Facilities

Information Technology Services currently operates a VAX 6420 (HKUCC), an IBM 9375 (HKUVM1), two DEC 5500 Ultrix servers (HKUXA and HKUXB) and 17 DECstation 5000/125 workstations, one SUN 670MP and one SUN SPARCCenter 2000 (HKUSUA) and 10 SUN IPX workstation and 6 SUN Classic workstations for general academic use. We are, nevertheless, expecting some major addition of central computing facilities. We have placed order for a IBM 9076 Scalable Power-Parallel system (IBM SP1) which should be arriving in the next few weeks. This system represents IBM's state-of-the-art technology for supporting computation -intensive applications. This system has eight processors and it boasts a theoretical peak performance of 1 GFLOPS (ie 1 billion floating operations per second). It should be a very valuable addition for our researchers, and will also help to alleviate the congested conditions in some of the other systems. Together with this system, we have also purchased 10 IBM M20 workstations and two high-resolution visualization workstations.

We are also expecting the arrival of two ALPHA systems from Digital Equipment Corporation. One is a server and one is a workstation. Again, this is Digital's latest 64-bit processor technology and we shall be doing some intensive evaluations on these two systems before making them available for general use.

There are other special purposes machines. The library system has recently been upgraded to a VAX 6510 and should be providing much better response to the users. We also maintain an IBM 9375 model 50 for the Management Decision Centre, a Micro-VAX II for network communication, another Micro-VAX II for supporting network access from the Faculty of Medicine, an IBM 6000/550 (DELPHI) for supporting the Dental Faculty and an IBM 4361 (HKUVM) for supporting the University's administrative applications.

This year, we have installed a two-processor high-availability system (HACMP 6000) from IBM to support our new administrative system. Current applications on the IBM 4361 will be converted to run on this system in phases. It is expected that some production jobs will be starting to run on this system in October/November, and we shall be able to provide our administrators with better response and information on this new system.

All our systems operate 24 hours a day, 7 days a week They will however be running unattended on all Sundays and public holidays For a new user, you will need to apply for a computer account in one of the host systems. This year, we have introduced a self registration system for students, which should shorten the time required to process their applications. We shall extend the scheme to other users in due course, but for the time being staff users would still have to fill in application forms, which are available from our General Office located at Room 223 Run Run Shaw Building. Please complete the form and return it to us for processing. The computer account will be valid until the user leaves the University.

Software installed in the different systems includes many popular programming language compilers, statistical packages, mathematical libraries, database management systems, engineering and graphic packages We have installed substantially more software this year.

For further details on the hardware and software configurations, please obtain a Computing Services Handbook from our General Office.

Microcomputer Facilities

In the open-space area in Information Technology Services i.e. Rooms RR-103 and RR- 104, we have set up numerous IBM PC compatibles and some Macintosh microcomputers. This is intended to serve our students who can simply walk into this area and use the facilities on their own This year we have installed additional high-end 80486 PC systems with color VGA displays. We have also upgraded the Macintosh systems in Room RR 104 to Mac LC III's.

These microcomputers are connected to a local area network and can access all the services on the campus network. Many programming language compilers, statistical packages, and word processing software are installed on the networks. Users may also bring their own software Most of these microcomputers are equipped with printer, graphic capability and micro-to-host communication capability To access these network facilities, users can purchase a special Start-up Diskette from our General Office. Laser printing services are provided at nominal cost for both the Macintosh network as well as the IBM PC compatibles.

There are also some IBM PC compatibles installed in the Fong Shu Chuen and Hsu Long Sing Student Amenities Centres, and in the Pauline Chan Building in the Medical Campus. These are available for student access only.

We have a few microcomputer laboratories which can be booked by teachers for conducting classes. Booking should be done two weeks in advance and can be arranged by calling Ms. Elsa Yung at 8592491. Details are described in a separate article in this newsletter. When our space in the Old Library System is ready for occupation, we shall have additional laboratories available.

Information Technology Services has arranged site licensing of some PC software as well as bulk-purchasing agreement on PC hardware and software from vendors, many of which are operated through the auspicious of UPCC (the University and Polytechnic Information Technology Services). Users are welcome to enquire on these low-cost hardware/software arrangements from our General Office.

Campus Network

All our centrally-located buildings in the main campus are now connected to the campus network, either through baseband copper Ethernet cables or fibre-optic cables. We have started to implement our FDDI backbone (100 Mbps) in the main campus and the various buildings will be connected in turn. When completed, it will give our network the much-needed increase in bandwidth to support the increasing network traffic and new image and multi-media applications. All teaching staff offices and departmental offices are also connected to the network and can benefit from the various services provided.

These include email service, bulletin board service, access to the Library catalogue system, access to all our central computer systems and the Internet.

Departments in the medical campus are connected via two 64K bps lines from the pre-clinical buildings (Li Shu Fan and Patrick Manson Building) and the clinical buildings (Professorial Block and New Clinical Buildings) to the main campus.

Another 64K bps line is also set up to connect the Dental Faculty to the main campus The University is connected to the other six tertiary institutions via HARNET (The Hongkong Academic and Research Network) through high speed T1-links, providing easy access to the other campuses We are also connected to the Internet, through a shared satellite link to the US. This link has recently been upgraded to 128K, with sponsor from the Hong Kong Telecom Foundation.

E-mail Service

E-mail (electronic mail) allows users to exchange information conveniently and economically within the same computer or within computer networks. Our computers are connected to HARNET - the Hongkong Academic and Research NETwork We are also a member of Internet and CREN; through which we can send e-mail to various overseas networks All users, staff and students, can use the international e-mail service, which is provided free of charge.

An introductory email user's guide, The VAX/VMS Electronic Mail User's Guide, is available from our General Office.

User Guides and User Document

This year, we have increased our training courses to staff and students New orientation courses to students and training workshops are introduced in September and October

To assist users in using the services and facilities, we have prepared a number of user guides and user documents These publications provide the basic information enabling users to start using our facilities They also indicate where additional details can be found The user guides can be purchased from our General Office while the user documents are available free of charge.

A list of all current user guides and user documents is recorded in User Document No 111 "Index to User Documentation" New handbooks include the VAX/VMS User's Guide Volume 1, the Network Services User's Guide and the UNIX User's Guide Users are strongly urged to get a copy of the Computing Services Handbook which gives a comprehensive description of our facilities and services.

Expansion of FDDI backbone in the Main Campus

The usage of the network has been increasing rapidly as our staff and students become more familiar with the campus network. In order to ensure the network are not congested, Information Technology Services has started to implement a FDD backbone in the Campus. We started last year with a 2- node FDDI connection between the Haking Wong Building and Information Technology Services. This year, Information Technology Services is going to extend the FDDI connection to more buildings in the main campus. The buildings that are going to be connected to the FDDI ring are:

  1. KK Leung Building (this building was successfully connected to the FDDI backbone on Sept 4)
  2. Knowles Building
  3. Library Building
  4. Main Building (this building will be connected to the FDDI backbone through the Library buildings
  5. Run Run Shaw Building
  6. Runme Shaw Building
The connection will be carried out one by one. With special thanks to the assistance of the Estates Office, the rewiring of some of the existing cable in the buildings have now been completed.

We shall modify the network settings of the Pcs, workstations and the host systems before switching over to the FDDI network. The modification of network settings involves the following works :

1. Information Technology Services will reconnect in phases all central host computer and workstations to the FDDI router which links up a building to the FDDI backbone. As the reconnection take place, the IP addresses of most of the reconnected host computers will be changed.

2. The IP addresses of your Pcs, MACs and host computers will remain unchanged

3. The IP subnet masks will be changed to 255.255.255.0 (i.e. 8 bit subnet mask). If your PC gains connection to the host computers through file servers managed by Information Technology Services, we shall perform the necessary changes. However, if your PC gains connection to the host computer through file servers managed by your department or if you install you own TCP/IP software on your computer (PC, MAC, workstation or host computers), you will have to make the changes yourselves.

4. The IP address of the routing gateways will be changed. Information Technology Services will assign a new routing gateway address to each department. Again if your PC gains connection to the host computers through fill servers managed by Information Technology Services, we shall perform the necessary changes. However, if your PC gains connection to the host computer through file servers managed by your department or if you install you own TCP/IP software on your computer (PC, MAC, workstation or host computers), you will have to make the changes yourselves

5. Some Novell file servers will have their IPX number changed. We sal perform these changes. And if the IPX number of the file server which is managed by your department needs to be changed, we shall contact the department to arrange for the changes.

The affected departments in each building will be informed in due course about the exact changeover date for connection to the FDDI router. In most cases user departments need not perform any task. However, if you have set up you own TCP/IP software on your computer as mentioned above, you must make the necessary changes stated above accordingly. If you have concerns regarding the modification of the network settings of your own TCP/IP on your computer please contact the undersigned immediately upon receipt notice of the changeover.

Internet link upgraded to 128 Kbps

Since the Internet access was first generally available to our users and those of our sister institutions last year, the many valuable services provided through Internet have been much well received. With the increasing number of users as well as their increased access to the Internet services, the 64 Kbps satellite data link for the Internet gateway of HARNET (Hongkong Academic and Research NETwork) had been running close to the limit of the data link bandwidth for some months. In order to improve the situation of data traffic congestion, the UPCC (University and Polytechnic Information Technology Services) had decided and proceeded to upgrade the Internet link to an operating speed of 128 Kbps.

We are pleased to announce that the upgraded Internet link which now operates at a speed of 128Kbps has been put into service since September 9, 1993. With this upgrade, users should find improvement in response time in using the various Internet services. We acknowledge the Hongkong Telecom Foundation for its continued sponsorship in upgrading the link.

The PC-session registration procedures include the Login and Logout steps which should respectively be followed to start and terminate each session. The registration procedures are as follows:

  1. Identify yourself by entering your student number or staff number.
  2. Enter your password, which is initially set to be the first six digits of your HKID/passport number.
  3. If the password is correct, a menu screen will appear and you can use the two cursor control arrow keys "->" and "<-" to select one of the options which could be "Login", "Logout", "NewPasswd" or "ChangePC".
  4. Select the "Login" option and then login one of the free PC's indicated on the screen (The power to the PC will be automatically turned on when you select and successfully complete the "Login" option.)
  5. At the end of your session, you need not turn off any switches of the PC system that you have used. However, you must return to the sam Registration Terminal, yourself, but then choose the "Logout" option of the menu this time. The power to the PC will then be turned off by the registration system and your session will be terminated.
  6. The "NewPasswd" option is provided to allow you to change your password if necessary.
  7. The "ChangePC" option is provided to facilitate the switching from one PC to another PC controlled by the same Registration Terminal.
Annual Renewal of PC User Accounts

User accounts for using Centre's PC facilities are created or renewed automatically each year for all University members. Individual application is therefore not required. The annual renewal of PC accounts was done on September 3 this year. Owing to the renewal, users should find their passwords on each of the registration stations reverted to the first 6 numeric digits of their HKID/passport numbers. If you wish to change your password, you can do so by selecting the 'Newpasswd' option at the registration stations. Please note that the registration stations work independently. This means that you change of password on any one of them will not affect your passwords on the others.

New Network Startup Diskettes for Centre's PC-systems

Two new Network Startup Diskettes have been devised to replace former versions of AT and 386/486 Network Startup diskettes used for Centre's PC-lab facilities.

1. This year, Information Technology Services has set up a new version of 'HKUPC1/HKUKKL2 AT Startup Disk'. This new version, ver9/93, will allow access to the Campus Network from all the PC-AT systems in the following locations:

Locations of PC-AT systems    Networks connected to
--------------------------    ---------------------
Rm-103, Run-run Shaw Bldg.           HKUPC1
Rm-218, Knowles Bldg.                HKUKKL2
Rm-LG-108, K. K. Leung Bldg.         HKUKKL2
This Startup diskette will configure the PC with MS-DOS 4.01 and have 386 KB RAM disk installed as C:.

As with the old AT Startup Diskette, this new version will present a HKUMENU-type interface on starting up, prompting the user to log in either HKUPC1 or HKUKKL2. Connection to the appropriate networks will then be made, according to the user's choice. Users should note that the HKUPC1 network is only accessible from rooms 101 and 103 of the Run Run Shaw Bldg., the HKUKKL2 network can only be accessed from LG-108 of the K. K. Leung Bldg. and Rm 218, Knowles Bldg. Accessing the network with a wrong choice will result in a startup failure.

2. Again, a new 386/486 Network Start-up Diskette labelled '386/486 Network Start-up MSDOS 6.0 Ver 9/93' has been produced. This new version will give all the 386 and 486 PC systems on HKUPC1 access to the network. It will configure the PC system as follows:

- MS-DOS 6.0

- 4 MB RAM disc as C: (for the 486DX-33, 8MB PC-systems in Room 103, Run Run Shaw Bldg.)

- 7 MB RAM disc as C: (for the 486DX-50, 16MB PC-systems in Room 101, Run Run Shaw Bldg.)

On starting up, the user will be prompted to identify the type of machine from which he/she is about to log on. There are 2 types of machines to choose from :

- 386/486 PC-systems in Room 103, Run-run Shaw Bldg.

- 486 PC-systems in Room 101, Run-run Shaw Bldg.

As these two types of machines have different configurations, users must identify correctly the kinds of machines they are using for successful start-up.

While users can still use the old 386/486 Network Start-up disk to start the 386/486 PC-systems in Room 103, Run Run Shaw Bldg., those 486 machines in Room 101 MUST be started up with the new version of start-up diskettes (VER 9/93). An item on HKUMENU named 'Generate new 386/486 Network Start-up Diskette' allows you to upgrade your old 386/486 start- ups to the new version.

Both Startup Diskettes can be purchased at the Laser-printing counter of Rm-103, Run Run Shaw Bldg., or at the General Office of Information Technology Services (Rm-223, Run Run Shaw Bldg.)
