GENERAL NEWS

HKU.CC.FORUM - An Additional User Communication Channel

At present, Computer Centre is providing three established channels to communicate with our users. They are the Help Desk, CCBOX and Computer News. The Help Desk located in Room RR-109 is a front line of contact for our users to seek for assistance in using Centre's facilities and services. CCBOX is an email channel for users to make enquiries, report technical problems as well as to provide suggestions or feedbacks for our facilities and services. All electronic mail enquiries to CCBOX are answered by our staff. Computer News is a Centre's newsletter which serves the functions of reporting and announcing Centre's new development and updated facilities and services.

Since the Usenet electronic bulletin board was first put into service, Computer Centre has set up the "hku.open-forum" newsgroup as a forum for University members to discuss any of their interested topics. As this newsgroup is not intended as a place for users to report problems or file their suggestions to any particular departments of the University, Computer Centre , like most other departments, has not officially participated in the discussions of the newsgroup. However, we have been treating the discussions in this newsgroup which are related to the Centre's services as feedback information for improving our service.

Recently, we have reviewed our user communication channels and decided to set up a new local newsgroup, called "hku.cc.forum", for discussions related to matters of Computer Centre . This new newsgroup will be available starting from July 1, 1995. For manpower consideration, our staff will respond to the discussions and issues raised in the "hku.cc.forum" in the form of a consolidated reply weekly.

The "hku.cc.forum" channel is set up as a new service. Centre's other user communication channels : Help Desk, CCBOX and Computer News will continue to serve their original purposes as mentioned in the first paragraph.

Dial-up TCP/IP PPP Service Supported

In the last few months, Computer Centre has been working hard to provide TCP/IP PPP support for its dial-up service. With such support, a user can use his PC at home to have full IP connection through dial-up lines and run the TCP/IP based communication applications, such as telnet, ftp, WWW ® browsers (e.g. Mosaic, Netscape), etc.

After suitable schemes for controlling legitimate access and regulating fair usage have been implemented, we are now very pleased to announce that starting from July 1, 1995, the dial-up modem pool with the number "25480590" will support the TCP/IP PPP operation mode in addition to the existing terminal access operation mode. For both the terminal access as well as PPP modes, the 60-minute maximum connection time limit of this group of lines remains unchanged. For the PPP mode, a maximum of 4 TCP/IP sessions is supported.

When you have gained access to a dial-up line of the "25480590" modem pool, you will be prompted to enter a username. For the usual terminal access, you can then enter "HKUDIAL" to call up a menu for starting terminal sessions on the Centre's host computers.

If you wish to use the TCP/IP PPP service, when you are prompted for the username, instead of entering "HKUDIAL", you have to enter your own PPP username and a password in one consecutive line separated by a '.' (e.g., h9314567.mypasswd). Note that if you are using the HKU PPP package (see below on how to get it), your PPP username and password will be prompted separately by a Windows-based dialog.

All staff and student users who have a valid computer account on a computer system of Computer Centre are eligible to apply for a PPP dial-up account through either HKUMENU or HKUWIN of the LAN file-servers which are set up and managed by the Centre. To apply through HKUMENU, you should first select the "Campus Wide Information Service", then select "Computer Centre " sub-menu and then select the "Apply-PPP-account" menu item.

To apply through HKUWIN, you should double click the "Apply-PPP-account" icon from the "HKUWIN: Central Network Services" application group. After the "Apply-PPP-account" program is started, you can then proceed to apply for your PPP account with the help information provided by the program.

HKUPPP Screen

In tandem with the provision of PPP support for the dial-up lines, the Centre has tailored a set of Windows based PPP dial-up package which consists of two installation diskettes to facilitate our users to use the network services through the TCP/IP PPP dial-up lines. The two installation diskettes of the PPP dial-up package and a copy of the Installation Guide can be obtained from the Centre's General Office, Room RR-223, at the nominal cost of HK$20. Alternatively users can download the PPP dial-up package, which include files "hkuppp.exe" and "hkuppp.w02", from the Centre's ftp server ftp.hku.hk under the directory /pub/hkuppp.

These two files should be saved to two separate diskettes. The Installation Guide can also be downloaded from the same directory in Microsoft Word format from the file "guide.doc". Please remember to use binary mode to transfer all these files. In using this tailored package, users are reminded to observe the terms and conditions of the usage of the software included in the package. Some of the software, e.g. Trumpet, is "shareware" which requires its user to register for a license if the software is to be used on a regular basis.

Should users have any problems or difficulties in using the TCP/IP PPP dial-up facilities, please contact the undersigned. Problems encountered after office hours can be reported to Centre's Computer Room (tel: 28592496).

The HKU World-Wide Web ® Service

With the introduction of the World-Wide Web ® (WWW ® ) service in Computer Centre since September 1994, many staff members have become aware of the tremendous potentials of WWW ® as an effective means of accessing and disseminating information through the worldwide Internet. In addition to text materials, WWW ® allows multimedia information including text, graphics, voice and video images be published, distributed and accessed through the global Internet.

There has been growing interest in the University community to make use of the WWW ® service. A number of departments (presently 18) have already put up their departmental information on "homepages" (entry points to the established WWW ® information) on the HKU World-Wide Web ® server.

As a result of the joint effort of the Academic & Faculty Services Section (AFSS) of the Registry, the Centre of Media Resources and Computer Centre , general information about the University of Hong Kong (compiled by the AFSS with photographs supplied by the Headquarters of the Registry) has also been added to the HKU World-Wide Web ® server. Users are encouraged to access the HKU homepage for information about the University.

Convenient access to the HKU WWW ® and other Internet WWW ® information within the University is supported by Computer Centre . Staff using networked PCs attached to LAN file-servers set up by Computer Centre and students working in our PC laboratories can run the Windows version of Mosaic or Netscape browser through the HKUWIN interface. Dial-up access to the HKU WWW ® server is also scheduled to be available from July 1, 1995 (see companion article on Dial-up TCP/IP PPP Service Supported in this Computer News).

To help the interested users to explore the World-Wide Web ® (Workshop A) and to set up multimedia information on the HKU WWW ® server for their departments (Workshop B), Computer Centre will continue to conduct these workshops on regular basis. During the coming summer, the following two workshops (only 20 places each) are scheduled. Further workshops will be arranged as necessary.

Frequently Asked Questions (FAQ) About HKUWIN

1. Q:How to start HKUWIN ?

A: Type HKUWIN and then press the ENTER key at DOS prompt. e.g.. C:\>

2. Q: Can I use HKUWIN on a 386 PC ?

A: The recommended configuration is a 486DX system with 8M RAM and SVGA colour monitor. It is still possible to run HKUWIN on a 486DX PC with 4M RAM or a 386DX PC with 8M RAM. However, the performance will only be marginally acceptable.

3. Q: I have already had the MS Windows and some Windows application programs installed on my harddisk, can I use these application programs after starting HKUWIN ?

A: Of course. If HKUWIN detects that you have a local Windows installed, it will add the 'HKUWIN : Central Network Services' (and a department application group if it has been set up by your department) to your Windows and all the properties of your local Windows will not be changed.

4. Q: Can I use HKUWIN without installing Windows ?

A: If you don't have Windows installed, HKUWIN will start the network Windows. You can still use the application programs maintained by Computer Centre . However, you cannot change the Windows properties e.g.. (colour, windows size, etc...).

5. Q: Why do I get the message 'Bad command or files' when starting HKUWIN ?

A1:Your computer may not be connected to the Campus Network. HKUWIN requires your PC to be connected to the Network. You can check this by changing the current drive to f: e.g. type f: and press the ENTER key at DOS prompt. If you get the message 'Invalid drive specification', it means that you are not connected to the network. Your PC can be connected to the Network by typing the "network" command and pressing the ENTER key.

A2: HKUWIN may not be installed in your departmental file server, please check with the technical staff of your department or contact the undersigned.

6. Q: What is the meaning of the following message '*** Your DOS is path too long, please reduce it before running HKUWIN' ?

A: You need to reduce the length of the path statement in the c:\autoexec.bat file, i.e. to remove some of the un-used path in the 'c:\autoexec.bat' file.

7. Q: The HKUWIN does not behave normally and I got the message 'Out of Environment Space' running over the screen when I started HKUWIN.

A: It means that your are running out of environment space. You can either reduce the number of 'set' statement in the 'c:\autoexec.bat' file by editing the autoexec.bat file to remove all unnecessary 'set' statements or to increase the environment space by adding a line 'shell=c:\command.com /p /e:1024' in the c:\config.sys file. If you already have this line in your config.sys file, you can increase the value further to 2048.

8. Q: I cannot start the HKUWIN and a lot of text messages are flashing on the screen when the HKUWIN command is invoked.

A: Your windows directory is not on the search path, please change the c:\autoexec.bat file by adding your Window's path to it, e.g. set path=c:\windows.

9. Q: What are the differences between reading E-mail by using the Eudora and connecting to a host computer?

A: Eudora provides a much user-friendly and easy to use user-interface, it has inherited all the advantages of Windows applications, e.g. cut and paste, point and click, etc,. However, please keep in mind that when using Eudora to read Email, all messages will be stored in your PC's harddisk and all messages that have been read will be removed from the host computer. It saves you time to download message from host on the expense of not getting the 'old-messages' by using another PC or the host computer.

10. Q: Should I use Eudora to process Email?

A: Eudora is recommended only if you have your own PC on your desktop and use it as the primary email reading machine. If you need to share your PC with others, do not use Eudora.

If you still have any queries while using HKUWIN, please contact the undersigned.

New Default Disk Quota

With the steady increase of our users' participation in network activities, e.g. WWW (World Wide Web), email, Usenet news etc., many users have found that their default disk quota is insufficient to cope with their work. In May this year, we have decided to increase the default disk quota of its host accounts from 1000 blocks to 2000 blocks for undergraduate students and from 3000 blocks to 4000 blocks for staff and postgraduate students.

Accounts which have been created since May 1995 have been given these new default disk quota value.

For accounts created before May 1995, their default disk quota has automatically been upgraded from 1000 to 2000 blocks or from 3000 to 4000 blocks depending on their account types.

We hope this increase in default disk quota value will help you to better use our facilities.
