Hi, I have some errors I don't know how to fix. I'm using freeradius 3.0.10 with lots of mikrotiks-hotspots connected and working apparently perfect. I'm adjusting to send on nasipaddress a unique IP for each mikrtoik-hotspot client. But now this is how looks raddact form 3 different hotspot-clients (each one on different ubications ) radacctid acctsessionid acctuniqueid username groupname realm nasipaddress nasportid nasporttype acctstarttime acctupdatetime acctstoptime acctinterval acctsessiontime acctauthentic connectinfo_start connectinfo_stop acctinputoctets acctoutputoctets calledstationid callingstationid acctterminatecause servicetype framedprotocol framedipaddress 16212900 80b0bb84 078cf7cca5b2a613beee2af0316de662 SwB_336391_ins_837_D8:1D:72:9C:35:49 192.168.32.4 bridge-hs Wireless-802.11 "2016-08-17 16:58:12" "2016-08-17 16:58:12" NULL NULL 0 0 0 606B051E73E5 D8:1D:72:9C:35:49 10.1.115.164 16212899 80b0017e 687f7a16adc44bbad5743f50c86e95f3 SwB_720082_ins_126_F4:31:C3:51:12:69 192.168.1.33 bridge-hs Wireless-802.11 "2016-08-17 16:58:09" "2016-08-17 16:58:09" NULL NULL 0 0 0 573205E971AE F4:31:C3:51:12:69 10.1.100.10 16212897 80500074 ca131c5822c708388105edc55430eb18 SwB_667778_ins_1441_58:7F:57:C3:97:E9 192.168.3.34 bridge-hs Wireless-802.11 "2016-08-17 16:58:05" "2016-08-17 16:58:05" NULL NULL 0 0 0 6431052C6C1E 58:7F:57:C3:97:E9 10.1.102.11 I don't know if it can be seen correctly. The Errors I'm getting during August: 1) 41.800 Error lines on log Fri Aug 12 22:54:32 2016 : ERROR: (47435677) detail: ERROR: Couldn't open file /var/log/radius/radacct/81.35.84.203/detail-20160812: Too many different filenames It only happens form 19:00 or 20:00 until 00:00:04 or so .. Seems a limitation of Centos 7 ? 2) 24.981 Error lines on log Mon Aug 15 17:41:21 2016 : Error: (48439939) Discarding duplicate request from client 0.0.0.0/0 port 60621 - ID: 195 due to delayed response This error appears 5 times from 1 to 15 August and from 15 august until now (24.981) lots of times evey hour ! Don't know how to find the client or radius request from ID 195 ... I didn't change anything from radius configuration so don't know why starts this error now. 3) 8.545 Errors lines on log Wed Aug 17 05:57:24 2016 : Error: Received conflicting packet from client 0.0.0.0/0 port 59102 - ID: 8 due to unfinished request. Giving up on old request. Wich are the keys parameters to identify each request differents ? In my configuration I'm working to identify each hotspot-client with a different nasipaddress but I don't know if it is enough . Thanks for the help ! Still difficult for me to understand everything from radius communication.
