Hi, I'm looking to implement the Simultaneous-User Value in radcheck. (FR 2.0.3) I'm having the issue that, for whatever reason (I'd blame the network in a heartbeat, not FR at all), the accounting for a logged in user never gets from a NULL acctstoptime to one filled in. At the current time, radwho on the server shows approximately 22 active users. In reality I think it'd be more like 1/2 of that. A "SELECT count( * ) FROM radacct WHERE acctstoptime IS NULL ;" shows 91 records. Due to the version of the NAS we are running (DD-WRT with Chillispot), we can't get checkrad to help true up the information. Is there another way to help keep everything in sync, so we don't have users who pay for a single ID, doing things like : lobnic14 00-13-02-25-8C- shell S1 Thu 17:3 192.168.7 192.168.182.3 lobnic14 00-1B-77-11-F4- shell S2 Thu 22:1 192.168.7 192.168.182.4 damrap6 00-0E-35-C0-16- shell S1 Thu 22:1 192.168.5 192.168.182.5 damrap6 00-11-24-8F-27- shell S3 Thu 20:2 192.168.5 192.168.182.10 damrap6 00-1B-77-06-2F- shell S4 Thu 20:2 192.168.5 192.168.182.11 Thanks, Tuc
