Hi I’m running freeradius 1.1.8 with rlm_exec. External program on ACCTOUNTING packets runs and my external program returns OK! And printout the following in its logfile: (PID 5036) 2011-09-15 18:24:28 Packet: updt UserName: hhsde0100413@tct9 187923@172.31.3.7 10320 Sec 3993228/61717432 Bytes FreeRADIUS Debugging shows log as the following and shows everything goes fine for that request.
