When these e-mail messages do not interest you, you may find them very annoying and adversely affecting your productivity.

To get rid of these junk messages, you can install filters in your mail client to automatically move them from your Inbox to a junk e-mail folder, your Deleted Items folder, or any other folder you specify.

Please click on the following link for the procedure to install filters in your mail clients such as Eudora, Netscape Messenger and Outlook Express :

Question & Answer: Virus Alert Messages and My E-mail Address
Question: Dear ITSC,

I got a virus alert message claiming that I've sent out a virus infected e-mail. However, I have never sent out this e-mail to the e-mail address as stated. Please find out what has actually happened.

Answer: Dear user,

Probably, it is due to Klez which is a mass-mailer worm which drops a polymporphic EXE virus called ElKern http://www.europe.f-secure.com/v-descs/klez_e.shtml.

Someone's computer has been infected by the Klez virus. This virus then propagated by sending itself to all addresses listed in the Microsoft Outlook, Outlook Express and ICQ address books. When the virus looked up past e-mails, it probably grabbed your e-mail address and then sent out e-mails using your name as found in an address book.

What can we do about it?

First, please do not trust the From: and To: addresses of your e-mail. Spammers and viruses know how to hide their identities. They put in misleading e-mail addresses in the To: and From: fields. What you see there is untrustworthy. You CANNOT tell who sent the infected email from that information. If you try to block incoming spam/viruses from those e-mail addresses, be aware that the infected files often change to something else after a while.

Currently, the ITSC is unable to customize our e-mail service to block some particular e-mail address for each individual user. It is simply because our servers are serving tens of thousands of users. Technically it is very impractical to implement such a filter at the server. Instead, such user-level filtering is best implemented by your own e-mail client program. Please see http://www.cuhk.edu.hk/itsc/network/app/email/filter/ for details.

To stop viruses from propagating, please be sure to have antivirus software installed on your computer. Also, update the virus pattern frequently. Please tell your friends and colleagues to do the same. If all the computers on campus are shielded from viruses, we shall see a lot less of the problems we are experiencing now. Check http://www.cuhk.edu.hk/avcentre for obtaining updated antivirus software.

Dial-up Quota Scheme Over the Summer
The utilization of the dialup lines has been closely monitored since the implementation of the Dial-up Quota Scheme. According to the usage collected in the last academic year, some of the quota lines are underused 90% of the time. This may be due to the popularity of the broadband service provided by ResNet and other Internet Service Providers. In order to save money for a better resource allocation, the ITSC has decided to cut 46 lines of 29330800.

To meet your dial-up access needs, we have revised the summer quota scheme which will be effective from June 3 until September 1 2002. Under this scheme, the prime hours have been shortened and the dialup weekly quota units for student users have been increased. As always, if you find the quota inadequate, please apply for extra units from the ITSC.

Please visit http://www.cuhk.edu.hk/itsc/network/dialup/quota for the scheme and other details.

User Area Summer Opening hours
From May 13 to Sep 2, the User Area at Pi Chiu Building will be opened as usual.

The schedule can be found at http://www.cuhk.edu.hk/itsc/about/opening-summer.html.

Have a happy summer vacation!
