Hi, running FreeRADIUS Version 3.0.4 (built for host x86_64-redhat-linux-gnu, built on Mar 5 2015 at 23:41:36) from stock packages on a CentOS 7 machine. I have the problem that I see Framed-IP-Address entries in radacct log files: Wed Dec 7 15:11:57 2016 Acct-Session-Id = '0004xxxx' Framed-Protocol = PPP Framed-IP-Address = 10.2.3.4 User-Name = 'user@example.com' Acct-Session-Time = 111 Acct-Input-Octets = 3499 Acct-Output-Octets = 5252 Acct-Input-Packets = 45 Acct-Output-Packets = 57 Acct-Status-Type = Stop Service-Type = Framed-User Acct-Delay-Time = 0 NAS-IP-Address = 12.13.14.15 Event-Timestamp = 'Dec 7 2016 15:11:57 CET' Acct-Unique-Session-Id = '297cb70bcbc4a02b1d1xyz123' Timestamp = 1481119917 but they're *not* being inserted into the MySQL database (field is empty, tcpdump shows that clearly a '' is being transmitted to MySQL): INSERT INTO radacct (acctsessionid, acctuniqueid, username, realm, nasipaddress, nasportid, nasporttype, acctstarttime, acctupdatetime, acctstoptime, acctsessiontime, acctauthentic, connectinfo_start, connectinfo_stop, acctinputoctets, acctoutputoctets, calledstationid, callingstationid, acctterminatecause, servicetype, framedprotocol, framedipaddress) VALUES ('0004xxxx', '297cb70bcbc4a02b1d1xyz123', 'user@example.com', '', '12.13.14.15', '', '', FROM_UNIXTIME(1481119920), FROM_UNIXTIME(1481119920), NULL, '0', '', '', '', '0', '0', '', '', '', 'Framed-User', 'PPP', '') Help very much appreciated.
