Hello,
After I've made your suggested change (inserted the Simultaneous-Use := 1 record into radgroupcheck table), the checkrad.pl script run, when I use radtest to a user, who is listed by radwho. I've set the $debug, $snmpget, $snmpwalk, $cmmty_string variables in the /usr/sbin/checkrad. After I get this message to checkrad's debug file: Fri Feb 12 14:13:19 2010 checkrad mikrotik 172.16.2.246 2147483647 hz00001 80600043 Returning 2 (error detected) Is there any settings to get more detailed debug info somewhere? I've set a firewall logger between the freeradius and the NAS client, but it has not any packet detected. The snmpwalk or telnet (to reach the mikrotik NAS) are working fine if I try them from a simple linux shell. Regards, fbi - List info/subscribe/unsubscribe?
