Hi, I have set up my new test environment with freeradius-1.1.0 ( with ldap and mysql ) and I just hit the wall as my VPN server ( poptop - MS PPTP ) crashed. I have a session left in my mysql db with "Acct-Stop = 0" which permits user to login again ( after the crash ) because simultaneous-use is set to 1. Are there any workarounds for this scenario? I've found deletestatlesssessions in sql.conf file, but I have no idea how does this work ( it is set to "yes" but no use ). Since my NAS is POPTOP server, type is set to "other" and checkrad cannot check ( or won't check ). At the end of the Simultaneous-Use doc it is mentioned that Idle-Timeout could be used, but this works for specific NASes and not for such VPN server that looses all info about users when crashed. Only way I figured out would be to check for open session before simultaneous-use-query. Since Ive configured my "NAS" to send accounting data every 2 minutes, it would be easy to say "delete all session data where traffic_data = 0 and time difference between now and session_start > 2 Minutes".. but where could I put such query. Does anyone have any suggestions on this topic? I know it is rather complex topic, but I would appreciate any opinions. TIA Regards, Edvin Seferovic PS: sorry for my HTML eMail today !
