A Unified Procedure for Accessing ACEnet, Wireless LAN and Hall Network
In Computer News issue no.103, we announced the enhanced
features for the Hall Network which allow the most commonly used network
services, such as email and WWW, to be used on the Hall Network (HallNet)
without going through the HKUVPN
authentication procedure. Now we are pleased to announce that
the same features will be extended to ACEnet and Wireless LAN users starting
from September 1, 2004. This new arrangement will bring more flexibility
and convenience to our users.
Users on the ACEnet and wireless LAN will be able to connect to the
campus network in either of the following ways (after registering their
(A) If the user only uses the following services, he can simply connect
his registered PC to the network using an Ethernet card or a wireless Ethernet
card without login to the HKUVPN gateway to enjoy the high-speed network
communications WITHIN the HKU Campus Network
and access the following popular Internet services:
WWW (http/https using default TCP ports: 80/443)
Streaming media (Microsoft Media Player & Real
ICQ connection (default TCP ports: 6667/5190)
*** Important note for ICQ users using
its file-transfer function:
(B) If the user wishes to do other kinds of Internet and Intranet communications,
he can login to the
if the file transfer is between two ICQ users within
the HKU Campus Network, "HKUVPN login" is optional, but faster transmission
can be achieved without it;
if one of the ICQ users is outside the HKU campus
network, BEFORE a file transfer, you must do the following:
Shut down ICQ => Login HKUVPN => Start ICQ => Do File-transfer.
Should you have any questions about the arrangement, you are welcome to
contact the undersigned.
Users are reminded that before accessing the ACEnet/WLAN or HallNet,
they must register their network cards through
the HKU Portal (=> "Services"
tab => "Register Network Card")
and they must configure their computers to "obtain
an IP address automatically" from the network.
A difference between the two methods of connection is in file transfer
(file upload from or download to a user's PC) using
an FTP program or via
the Internet Explorer browser. Without logging in the HKUVPN
gateway, you cannot perform file transfers.
