Hello Here's what I have done
I inserted ("dialup", "Simultaneous-Use", ":=", "1") into radgroupcheck. And I uncommented simul_count_query and simul_verify_query on sql.conf. After I done that I when I looked at the radius.log.And it seemed that it's catching multiple logins. But it turns out that radius is denying dialup users,even though login is not multiple login. When I looked at simul_count_query,it looked like this query just count the number of records that have AcctStopTime is 0 for a certain user. So I searched our radacct table and found almost 120000 records that have 0 as AcctStopTime.(Most of them are dial-up customers). And It looked like most of dial-up customers have at least one records with 0 as AcctStopTime. So I want to know is that . The reason why dial-up customers couldn't login when I uncommented simul_count_query and simul_verify_query is because dial-up users have records with 0 as AcctStopTime and the way simul_count_query works? Am I correct? If not can someone help me out? Thanks in advance Simon _________________________________ Simon Son New Zealand Online Tech Ltd.
