Currently the monitoring of peak hour usage detects and logs multiple concurrent dialups for the same username. On the average there are a dozen users each week that this happens to. A disconnect script exists and it would only require a call to this script from the concurrent detection script. There is a tendency for these students to disreguard limits and acceptable uses. Bob McNaughton has supplied me a list of these students that can be put into a special group with special limits.
Futher testing is needed.
Currently peak hours are defines as Sunday through Thursday 6pm to Midnight. An alternative to this would be to descrease the total number of hours per week to something below the current 16 hours. Setting a limit of 5 hours per week would allow users two 30 minute sessions each evening. If the service becomes popular, more modems from the regular modem pool could be added to this service. Some testing needed and will be done between Spring and Summer term.
