Hi all.... In the file radiusd.c, i am not able to understand the following... what is "fake request" and what is duplicate requests??????? when a request is considered as duplicate??? /* * "fake" requests MUST NEVER be in the request list. * * They're used internally in the server. Any reply * is a reply to the local server, and any proxied packet * gets sent outside of the tunnel. */ rad_assert((curreq->options & RAD_REQUEST_OPTION_FAKE_REQUEST) == 0); /* * The current request isn't finished, which * means that the NAS sent us a new packet, while * we are still processing the old request. */ if (!curreq->finished) { /* * If the authentication vectors are identical, * then the NAS is re-transmitting it, trying to * kick us into responding to the request. */ if (memcmp(curreq->packet->vector, packet->vector, sizeof(packet->vector)) == 0) { RAD_SNMP_INC(rad_snmp.auth.total_dup_requests); /* /* * It's not finished because the request * was proxied, but there was no reply * from the home server. */ if (curreq->proxy && !curreq->proxy_reply) { /* * We're taking care of sending * duplicate proxied packets, so * we ignore any duplicate * requests from the NAS. * * FIXME: Make it ALWAYS synchronous! */ if (!mainconfig.proxy_synchronous) { RAD_SNMP_TYPE_INC(listener, total_packets_dropped); DEBUG2("Ignoring duplicate packet from client " "%s:%d - ID: %d, due to outstanding proxied request %d.", client_name(packet->src_ipaddr), packet->src_port, packet->id, curreq->number); Thanks.... --------------------------------- Once upon a time there was 1 GB storage on Yahoo!
