[Serusers] SER Newbie

Hello list, I'm new in SER, and i have problem setting up the application. I have asterisk pbx using SIP and a billing application for voip using radius authentication. The billing use MSSQL database and the Radius server is under Linux. I installed radiusclient on the same machine with ser-0.8.11-0.rpm. The problem is that when I do: ser start, I have this: 127.0.0.1 [127.0.0.1]:5060 XXX.XXX.XXX.XX [XXX.XXX.XXX.XX]:5060 Aliases: host-XXX-XXX-XXX-XX.interpacket.net:5060 localhost:5060 localhost.localdomain:5060 SER:5060 XX is the IP of the SER machine. But when I do "serctl monitor", I got this: [cycle #: 1; if constant make sure server lives and fifo is on] And nothing happen. This tells me that ser is not running. Can somebody help me with my setup. Thanks. Daniel
