ITS has installed a high-speed and sophisticated campus network based on 10-Gigabit Ethernet and Fast Ethernet technologies with over 57,000 network access points installed which links together all the computer servers, workstations and PCs in the main and remote campuses.
Wireless access to the campus network and Internet is provided by over 9,200 WiFi access points and is available in all centrally-administered classrooms, public areas in the main campus, department offices and halls of student residence. Apart from the University’s WiFi network “HKU”, students can also enjoy WiFi access off-campus at CSL and Y5Zone WiFi hotspots in town, and at other local and overseas universities using “eduroam”.
The University of Hong Kong is a member of the Joint Universities Computer Centre (JUCC) that manages HARNET (the Hongkong Academic and Research NETwork) and coordinates inter-campus network services among the eight tertiary institutions in Hong Kong. The HKU campus network is connected to other tertiary institutions in Hong Kong through a resilient network backbone of HARNET supporting two 10Gbps ports at each institution to cater for future expansion.
ITS, through the Learning Environment Services (LES) Team, looks after the central learning environment of the University, comprising classrooms, lecture theatres and Chi Wah Learning Commons. A wide variety of facilities is provided to support the technology-enabled learning experience. For example, the Digital Literacy Laboratory (DLL) has powerful iMacs and well-equipped production studios together with technical support for multimedia production. Communal PCs come with the latest version of software packages, including word-processing, web page design, graphical and multimedia tools, and statistical analysis. uPrint Service (laser printing service) is available for both communal and personal laptop computers which are connected to the campus network through WiFi.
ITS provides a wide range of IT support services to members of the University. Orientation courses are offered to new students at the start of each academic year. Regular IT seminars, induction courses and training workshops on popular IT topics and commonly used software packages are also held throughout the year. Students can contact the Service Desk through the multiple channels described at https://its.hku.hk/service-desk/ to get assistance in using the central IT services.
Please visit https://its.hku.hk/students/ and https://its.hku.hk/kb/information-technology-services-guide/ on how to get started in using the central IT services. Students can also refer to ITS homepage at http://its.hku.hk/ for its popular facilities and services.
1.HKU Portal UID and PIN
The HKU Portal UID and PIN will be distributed to new students upon admission registration. Thus, no application is required. The pre-assigned UID begins with “h” or “u” followed by the 3rd to the 9th digits of the HKU student number. For example, if the 10-digit student number is 2022567890, the pre-assigned UID will be h2256789 and the corresponding email address will be h2256789@connect.hku.hk. Similarly, if the student number is 3031234567, the pre-assigned UID will be u3123456 and the corresponding email address will be u3123456@connect.hku.hk.
Students can change their pre-assigned UID (once only during the entire study at the University) within 7 days after master registration is completed if they prefer to choose another UID. A fee of HK$200 will be charged for subsequent requests to recover part of the administrative overhead. The UID chosen should resemble his name. ITS reserves the right to disapprove any chosen UID which is deemed inappropriate.
Students are strongly advised to change their initial PIN as soon as possible and keep their PIN confidential to protect their personal information. The change of PIN can be done via the HKU Portal at https://hkuportal.hku.hk (type “pin” in the Search field and click the link “Change HKU Portal PIN”). Students can change their PIN online anytime through their mobile phone number or alternate email address if such information is provided when they change their initial PIN.
2.Connecting to the HKU Network
The network connection procedures for connecting to the campus network can be found at https://its.hku.hk/services/network-connectivity/.
Students can also access the “Wi-Fi.hk via HKU” service (requires no prior configuration) before their mobile devices are configured for connecting to the University’s WiFi network, “HKU”. However, Wi-Fi.hk via HKU is only for quick and immediate network access in an unsecure mode within limited bandwidth. More details can be found at https://its.hku.hk/kb/accessing-wi-fi-hk-via-hku-service/.
In summary, after the one-time configuration and registration of a PC/mobile device, students can access Internet services from the HKU campus without further configuration steps.
For accessing the campus network services outside the University network, students can use the HKU Virtual Private Network (HKUVPN). Access to HKUVPN requires 2-Factor Authentication (2FA) which means on top of HKU Portal UID/PIN, a one-time token code has to be provided to complete the login step. New students will have 2FA registered for them automatically when they change their initial PIN.
A one-time token code will be sent to students’ registered alternate email address every time when they make a VPN connection. Please refer to our webpage at https://its.hku.hk/kb/hkuvpn-connection-with-2fa/ for the configuration and connection steps.
3.Protect Your PC from Computer Viruses and Network Attack
Students must protect their PCs vigilantly against computer viruses, trojan horses and spyware because they affect not only the operation of their PCs but also the performance of the entire campus network and the Internet. It is every user’s responsibility to do the following (more details available at https://its.hku.hk/kb/healthy-and-environmentally-friendly-pc/):
| (a) | Perform Windows Critical Update whenever new critical update is available. |
| (b) | Install anti-malware software on the PC and update it with the virus and spyware definition file daily, preferably to be done immediately after the PC is started up. Students can download one copy of the Sophos anti-malware software for use on their PC during their studies at the University under HKU Portal (type “Sophos” under the Search field of HKU Portal and click the searched link “Download Sophos Anti-Virus”). |
| (c) | If a PC is infected with a virus, the virus may disable it from accessing anti-virus web sites and so it cannot be updated with the latest virus definition file. Please refer to the FAQ at https://its.hku.hk/kb/my-pc-is-infected-with-a-virus-i-cannot-connect-to-the-network-to-update-my-virus-definitions/ for the necessary action to take. |
| (d) | Do NOT open suspicious mail or attachment from unknown/suspicious source. |
| (e) | Do NOT visit suspicious web sites or click on unknown web links. |
| (f) | Always remember to switch off a PC when not in use for a prolonged period to reduce its chance of being attacked and if infected, to attack other computers or the network. This also saves energy. |
