OpenACS

In order to avoid the problem that students might participate on exams

intended to be held e.g. on campus from at home, one can now restrict

the access based on IP ranges. It is possible to restrict the access

via multiple range blocks that can be predefined by the sysadmins. One

could predefine e.g. IP range blocks for "Campus LAN", "On Site",

"VPN", etc., which can be selected by lecturers for individual exams.

Every IP range block can be defined via multiple entries of disallowed

and allowed IP ranges, where the addresses can be specified via IPv4

or IPv6 CIDR blocks (e.g. 127.208.0.0/16), or with wild cards or

individual IP addresses.  The usage of CIDR blocks requires an update

to the updated version of NaviServer.

The IP restriction is used in the current implementation for

restricting the regular start of the exam (proctored or

non-proctored). Lecturers can still perform test runs for exams with

restricted access.
