I've been getting bombarded with old acct info, and looking into it, I believe the reason the NAS keeps sending the same info over and over again, is because radiusd isn't sending back any accounting-response. Here is the debug output, I do notice that the session time is zero and radiusd doesn't like that, but would that prevent radiusd from sending back an accounting-response? rad_recv: Accounting-Request packet from host 198.88.216.4 port 1647, id=141, length=278 Event-Timestamp = "Jul 13 2007 17:12:30 CDT" User-Name = "spierce@illicom.net" NAS-IP-Address = 204.42.16.5 NAS-Identifier = "tnt1.core.peoria.il.bwsys.net" NAS-Port = 1429 NAS-Port-Type = Async Service-Type = Framed-User Acct-Status-Type = Stop Acct-Delay-Time = 13813416 Acct-Session-Id = "439719181" Acct-Terminate-Cause = NAS-Request X-Ascend-Disconnect-Cause = Unknown X-Ascend-Connect-Progress = IPNCP-Opening X-Ascend-PreSession-Time = 27 X-Ascend-Pre-Input-Octets = 352 X-Ascend-Pre-Output-Octets = 349 X-Ascend-Pre-Input-Packets = 11 X-Ascend-Pre-Output-Packets = 13 X-Ascend-Data-Rate = 28800 X-Ascend-Xmit-Rate = 37333 X-Ascend-Multilink-ID = 268768248 X-Ascend-Num-In-Multilink = 0 Acct-Link-Count = 1 Acct-Multi-Session-Id = "100513f8" X-Ascend-Modem-PortNo = 31 X-Ascend-Modem-SlotNo = 15 X-Ascend-Modem-ShelfNo = 1 X-Ascend-Data-Svc = Switched-Voice-Bearer Framed-Protocol = Ascend-MP Framed-IP-Address = 0.0.0.0 Proxy-State = 0x3139 Processing the preacct section of radiusd.conf modcall: entering group preacct for request 2209 rlm_acct_unique: WARNING: Attribute Client-IP-Address was not found in request, unique ID MAY be inconsistent rlm_acct_unique: Hashing 'NAS-Port = 1429,,NAS-IP-Address = 204.42.16.5,Acct-Session-Id = "439719181",User-Name = "spierce@illicom.net"' rlm_acct_unique: Acct-Unique-Session-ID = "a9c91b40cff69183". rlm_realm: Looking up realm "illicom.net" for User-Name = "spierce@illicom.net" rlm_realm: Found realm "illicom.net" rlm_realm: Adding Stripped-User-Name = "spierce" rlm_realm: Proxying request from user spierce to realm illicom.net rlm_realm: Adding Realm = "illicom.net" rlm_realm: Accounting realm is LOCAL. rlm_realm: Request already proxied.
