I am sorry to post but I am just not getting something right here. I have been running this freeradius server for quite some time with no problems. I have just now decided that I want to solve the Simultaneous-Use problem. I am using 1.0.2 and a mysql database located on another server. I have followed everything that I can find on the net about the configuration but I can still logon the same user as many times as I want. It may help to know that the radius server is only being used by a website script for login (chillispot). For my needs I am not setting up any groups or anything special in the database. I am basically only dealing with the radcheck table. This is the only table that has the usernames and passwords. All the other tables seem not to be needed for what I am doing. I am open to suggetion of course if I need to add entries into any other table to make simultaneous-use work. here are my conf files sql.conf ---------------------------- sql_user_name = "%{User-Name}" simul_count_query = "SELECT COUNT(*) FROM ${acct_table1} WHERE UserName='%{SQL-User-Name}' AND AcctSessionTime = 0" simul_verify_query = "SELECT RadAcctId, AcctSessionId, UserName, NASIPAddress, NASPortId, FramedIPAddress, CallingStationId, FramedProtocol FROM ${acct_table1} WHERE UserName='%{SQL-User-Name}' AND AcctStopTime = 0" group_membership_query = "SELECT GroupName FROM ${usergroup_table} WHERE UserName='%{SQL-User-Name}'" postauth_query = "INSERT into ${postauth_table} (id, user, pass, reply, date) values ('', '%{User-Name}', '%{User-Password:-Chap-Password}', '%{reply:Packet-Type}', NOW())" radiusd.conf ------------------------------- instantiate { exec expr } authorize { preprocess chap mschap suffix sql } authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type MS-CHAP { mschap } } preacct { preprocess suffix } accounting { acct_unique detail unix sql radutmp } session { radutmp } post-auth { } pre-proxy { } post-proxy { eap } any suggestions? thanks -Blake
