Dear Alan DeKok
Sorry for asking bothering question again.
I don't solved yet Simultaneous-Use. Few days ago I've installed new version FreeRADIUS 2.1.8. Before(a year ago) radutmp utility didn't show the current connected users but this time it works I get logged in
users data in radutmp file then I hope may new release of FreeRADIUS provides other method than SNMP to check the Simultaneous-Use.
Before I've tried using SNMP with Cisco NAS no success.
I'm look forward hearing from you.
Best regards,
Tseveen.
