Dear List Members, i have working setup of FreeRadius 2x (freeradius-2.1.12-4.el6_3.x86_64) including "rlm_sqlcounter" (Max-Daily-Session). User are logged off alright when "Max Session Timeout" is reached. But users can re login to gain access. The username and passwords are for hotspot. We do not want the username and password to work again once it has been used. For example: prepaid voucher (MySQL username & password) has 1 hour access. User should be able to use sum of one hour, either continuously once they are logged in or in parts (30min today & 30min tomorrow so on) username & password must never work for more than 1 hour to access our network. After the research i configured "Access Period" attribute using rlm_sqlcounter. According to the logs accessperiod counter is configured correctly and it returns OK. But users can still re use the one hour voucher (username/password). Is there any entry required in "/etc/raddb/dictionary" file for it to work? Something is still missing or i am not using correct attribute for the purpose. i would very grateful if someone can identify what is missing in my configuration or advice the correct attribute to use. I have tried the following: STEP A: Created rlm_sqlcounter and query. sqlcounter accessperiod { counter-name = Max-Access-Period-Time check-name = Access-Period sqlmod-inst = sql key = User-Name reset = never query = "SELECT IFNULL(TIME_TO_SEC(TIMEDIFF(NOW(), MIN(AcctStartTime))),0) FROM radacct WHERE UserName='${key}' ORDER BY AcctStartTime LIMIT 1;" } LOGS FOR ACCESS PERIOD COUNTER USING radiusx -X: rlm_sqlcounter: Sent Reply-Item for user prabhpal, Type=Session-Timeout, value=3600 ++[accessperiod] returns ok STEP B: "radiusd.conf" instantiate { exec expr daily noresetcounter dailycounter monthlycounter accessperiod expiration logintime } STEP C: authorize { some other entries ... daily noresetcounter dailycounter monthlycounter accessperiod expiration STEP D: assign the access period attribute to user or group STEP E: Restart radiusd & Testing Thanks
