Dear All, I am running freeradius 2.10 with mysql for some time now, currently on Ubuntu 9.10, NASes are various router models running Openwrt and Coova-Chilli. I am having trouble with my radacct table. Which creates some 80k entries per annum. For about 1% of users it contains doubled up entries (entries with same AcctSessionId and same AcctUniqueId) and also lots of entries with the Username being empty (as opposed to either filled or Null). Example extract from radacct: RadAcctId AcctSessionId AcctUniqueId UserName Realm NASIPAddress NASPortId NASPortType AcctStartTime AcctStopTime AcctSessionTime AcctAuthentic ConnectInfo_start ConnectInfo_stop AcctInputOctets AcctOutputOctets CalledStationId CallingStationId AcctTerminateCause ServiceType FramedProtocol FramedIPAddress AcctStartDelay AcctStopDelay xascendsessionsvrkey 202678 4c2c5c7200000002 b50051a7f2d0e210 jasdoxur7 192.168.182.1 2 Wireless-802.11 2010-07-01 21:14:47 2010-07-02 01:12:18 14251 8100124 28550967 00-15-6D-DA-E0-59 00-13-02-89-7D-8E Lost-Carrier 192.168.182.25 0 0 203366 4c2ce6de00000001 584e51b205634c34 jasdoxur7 192.168.182.1 1 Wireless-802.11 2010-07-02 07:10:24 2010-07-02 10:38:35 12491 8620576 48189131 00-15-6D-DA-E0-59 00-13-02-89-7D-8E Lost-Carrier 192.168.182.2 0 0 203370 4c2ce6de00000001 584e51b205634c34 jasdoxur7 192.168.182.1 1 Wireless-802.11 2010-07-02 07:10:24 2010-07-02 10:38:35 12491 8620576 48189131 00-15-6D-DA-E0-59 00-13-02-89-7D-8E Lost-Carrier 192.168.182.2 0 0 203374 4c2ce6de00000001 584e51b205634c34 jasdoxur7 192.168.182.1 1 Wireless-802.11 2010-07-02 07:10:24 2010-07-02 10:38:35 12491 8620576 48189131 00-15-6D-DA-E0-59 00-13-02-89-7D-8E Lost-Carrier 192.168.182.2 0 0 203378 4c2ce6de00000001 584e51b205634c34 jasdoxur7 192.168.182.1 1 Wireless-802.11 2010-07-02 07:10:24 2010-07-02 10:38:35 12491 8620576 48189131 00-15-6D-DA-E0-59 00-13-02-89-7D-8E Lost-Carrier 192.168.182.2 0 0 204458 4c2dd9a900000006 e3dbcb6e1e8d44dc jasdoxur7 192.168.182.1 6 Wireless-802.11 2010-07-03 00:26:33 2010-07-03 01:28:16 3702 6564061 23169066 00-15-6D-DA-E0-59 00-13-02-89-7D-8E User-Request 192.168.182.28 0 0 204462 4c2dd9a900000006 e3dbcb6e1e8d44dc jasdoxur7 192.168.182.1 6 Wireless-802.11 2010-07-03 00:26:33 2010-07-03 01:28:16 3702 6564061 23169066 00-15-6D-DA-E0-59 00-13-02-89-7D-8E User-Request 192.168.182.28 0 0 204466 4c2dd9a900000006 e3dbcb6e1e8d44dc jasdoxur7 192.168.182.1 6 Wireless-802.11 2010-07-03 00:26:33 2010-07-03 01:28:16 3702 6564061 23169066 00-15-6D-DA-E0-59 00-13-02-89-7D-8E User-Request 192.168.182.28 0 0 204470 4c2dd9a900000006 e3dbcb6e1e8d44dc jasdoxur7 192.168.182.1 6 Wireless-802.11 2010-07-03 00:26:33 2010-07-03 01:28:16 3702 6564061 23169066 00-15-6D-DA-E0-59 00-13-02-89-7D-8E User-Request 192.168.182.28 0 0 204474 4c2dd9a900000006 e3dbcb6e1e8d44dc jasdoxur7 192.168.182.1 6 Wireless-802.11 2010-07-03 00:26:33 2010-07-03 01:28:16 3702 6564061 23169066 00-15-6D-DA-E0-59 00-13-02-89-7D-8E User-Request 192.168.182.28 0 0 204478 4c2dd9a900000006 e3dbcb6e1e8d44dc jasdoxur7 192.168.182.1 6 Wireless-802.11 2010-07-03 00:26:34 2010-07-03 01:28:16 3702 6564061 23169066 00-15-6D-DA-E0-59 00-13-02-89-7D-8E User-Request 192.168.182.28 0 0 205110 4c2e6be700000002 1bbe9ab0e9e6321b jasdoxur7 192.168.182.1 2 Wireless-802.11 2010-07-03 10:54:33 2010-07-03 11:14:45 1212 585059 2206797 00-15-6D-DA-E0-59 00-13-02-89-7D-8E Lost-Carrier 192.168.182.6 0 0 205950 4c2f201400000007 390a572eaaf851c9 jasdoxur7 192.168.182.1 7 Wireless-802.11 2010-07-03 23:37:55 2010-07-04 00:13:48 2153 4465894 50532205 00-15-6D-DA-E0-59 00-13-02-89-7D-8E Session-Timeout 192.168.182.23 Here an extract of the sqltrace.log, which shows how the UserName is empty: UPDATE radacct SET framedipaddress = '192.168.182.2', acctsessiontime = '6120', acctinputoctets = '0' << 32 | '16465104', acctoutputoctets = '0' << 32 | '23727469' WHERE acctsessionid = '4c32447800000001' AND username = 'gencafot7' AND nasipaddress = '192.168.182.1';

My sql statements are standard dialup.conf, with Simultaneous Use Checking Queries and Case Sensitive User queries switched on. What could cause the doubled up radacct entries and what might cause the empty UserName radacct updates? Any advice welcome. Thanks
