You set your idle time and max call length to unlimited in the
portmasters.
You create a config file that defines all users (in a global section) and
then you list by username other looser or tighter restrictions.
PortMan will monitor your PM's and TCH's.
The way I have it set is like this:
If we have more than 30 free modems in our 215 pool let them stay on as
long as they want with idle times as long as they want.
When we are between 30 and 15 free modems impose a 30 min idle time and an
8 hour max connect. This is ACTIVE, it will look at idle and max connects
and kick them off even though the portmaster it is still set to unlim
idle and unlim length connects.
When we have less than 15 free modems then kick off all free accounts and
employees. Dump anyone who is idle for 20 or more minutes. Dump all
users who have been on for more than 6 hours.
