Accounting help please

Hello, I have freeradius2 configured and authenticating properly. I would like to be able to get radwho and radlast working properly, but for some reason the files do not get created (permission are correct in that directory). I thought I have set up accounting correctly, but obviously haven't. I have attached the output from radiusd -X, any pointers anyone could give me, I would appreciate. The output I get from radwho and radlast is: [root@samba raddb]# radwho radwho: Error reading /var/log/radius/radutmp: No such file or directory [root@samba raddb]# radlast last: /var/log/radius/radwtmp: No such file or directory Thanks! -- Cheers, David
