[Users] How can I send radius authentication packet with openser

Hi, I have installed openser, mysql, radiusclient-ng-0.5.2 successfully on REL3.0. openser works well with mysql. I need to send a radius authentication packet to a radius server(according to RFC2865). Packet contains base params: User-name (attr.1) $Username Password (attr.2) $Password NAS-Identifier (attr.4) (auto-generated) NAS-Port (attr.5) $uref State (attr.24) 0 Client-Port-DNIS (attr.30) NONE Caller-Id (attr.31) $calling I can not find a clear sample about radius. Which module is used for this purpose? Regards Arda
