We've set up Simultaneous-Use := 1 - and this seems fine. However, I have my first user - who is really off the net and 'radzap' seems to do nothing.... (radwho still gives the user as being there). What is the code... in sql.conf... simul_count_query = "SELECT COUNT(*) FROM ${acct_table1} WHERE UserName='%{SQL-User-Name}' AND AcctStopTime = 0" ...for???? In our previous Radius - we used to simply provide a valid AcctStopTime time - and the user could then login again. What do I need to do to change freeradius to do Simultaneous-Use control using mysql and not using radwho?? I've read doc/Simultaneous-Use - which doesn't use/mention [my]sql. I'm guessing (looking at where radutmp is mentioned)... radiusd.conf has... session { radutmp } Should this be changed to... session { sql } ??? -- . . ___. .__ Posix Systems - Sth Africa. e.164 VOIP ready /| /| / /__ mje@posix.co.za - Mark J Elkins, Cisco CCIE / |/ |ARK \_/ /__ LKINS Tel: +27 12 807 0590 Cell: +27 82 601 0496
