Hku Sophos Portal
| Information Technology Services (ITS), provides comprehensive information technology services with a state-of-the-art IT environment to support teaching, learning, research and administration of the University. Its facilities include an advanced campus network, powerful central servers, high-performance computer (HPC) clusters, cloud computing and modern learning environment, and its services include unified communication, portal services, learning management system “Moodle” and web-based administrative applications. HKU Portal Services ITS runs 24-hour, non-stop system and network services to support the IT needs of the University. All students are given a computer account, identified uniquely by a HKU Portal UID (User Identification) and an associated PIN (Personal Identification Number), for accessing a wide range of network services and applications conveniently. The HKU Portal provides a user-friendly and easy-to-access interface for University members to access all the centrally provided IT services including services offered under the Student Information System (SIS), electronic mail, learning management system, web-based administrative applications, and Library services through a high-speed campus network. Computer and Research Support Facilities Powerful central computer servers support various web-based applications, departmental web sites and electronic email. ITS provides expertise and central support in high performance computing (HPC) and Cloud/Grid Computing to facilitate compute-intensive research activities of the University. There is a 2,320-core HPC system (theoretical peak power of 103.4 Tera-FLOPS) equipped with the latest technologies, including Nvidia Graphics Processing Unit (GPU), Intel Many Integrated Core (MIC) and Lustre parallel file-system, for supporting compute-intensive and accelerated computing. Software packages for supporting engineering computation, scientific applications, simulations, graphics applications and statistical analysis are installed on these servers. Please refer to the website at http://www.its.hku.hk/services/research for more details. HKU Campus Network ITS has installed a high-speed and sophisticated campus network based on 10-Gigabit Ethernet and Fast Ethernet technologies with over 53,800 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 5,700 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 optical network backbone of HARNET that is built on the most advanced optical network platform supporting two 10Gbps ports at each institution to cater for future expansion. HARNET is connected to HKOX (Hong Kong Open Exchange) which serves as an important research and education network hub and connects to other National Research and Education Networks including TEIN (Trans Eurasia Information Network), SingAREN (Singapore Advanced Research and Education Network) and KREONET (Korea Research Environment Open NETwork). Cloud Computing Cloud computing refers to the delivery of computing and storage capacity as a service to a heterogeneous community of end-recipients. ITS has implemented a private cloud infrastructure to better support the University’s dynamic computing needs. The service portfolio includes provision of Platform as a Service (PaaS) in the first instance followed by application Software as a Service (SaaS). Learning Environment ITS, through the Learning Environment Services (LES) Team, looks after the central learning environment of the University, comprising classrooms, lecture theatres, Chi Wah Learning Commons, The Oval (1/F of Knowles Building), The Curve (1/F and 2/F of KK Leung Building) and Study Lounge (MB238 of Main Building). 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 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. A Materializer 3D Printer is also available in the Chi Wah Learning Commons. To know more about available facilities, please refer to the website at http://www.les.hku.hk. User Services 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 may visit the Service Desk and the General Enquiry Counter on the 1/F of Library Building (Old Wing) or through the multiple channels described at https://www.its.hku.hk/service-desk to get assistance in using the central computing and network services. For more information about the services of ITS, please visit its web site at http://www.its.hku.hk. Important Notes To New Students 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 2019567890, the pre-assigned UID will be h1956789 and the corresponding email address will be h1956789@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 $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 http://www.its.hku.hk/services/network/connect. 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, the 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 http://www.its.hku.hk/documentation/guide/network/wifi/wifihk. 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 http://www.its.hku.hk/documentation/guide/network/remote/hkuvpn2fa 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 http://www.its.hku.hk/services/infosec/awareness/healthy-pc):
4. Policies and Regulations All students are required to abide by the policies and regulations in using the University’s computer and network facilities and services.
