Hi All, I have configured freeradius 3.0.19 as proxy server which forwards radius accounting packets to specific home servers based on NAS IP. The problem I am having is once the connectivity to the home server goes down, the radius proxy can not reestablish the connection to the home server. If I delete detail and detail.work files and restart the freeradius service everything starts working well. I was wondering if I am missing something in configuration that is causing this problem. Here is the log detail (/var/log/freeradius/radacct/detail): Read packet from /var/log/freeradius/radacct/detail.work Acct-Session-Id = "5D8840F4-8E040D01" Framed-IP-Address = 192.168.0.1 Acct-Multi-Session-Id = "3087d99a131824da33a490c45d8840f5000d" Acct-Link-Count = 1 Acct-Status-Type = Interim-Update Acct-Authentic = RADIUS User-Name = "abcd@abcd.co.nz" NAS-IP-Address = 10.0.0.10 NAS-Identifier = "30-8D-D9-9D-13-18" NAS-Port = 1 Called-Station-Id = "30-8D-D9-9D-13-18:ABC" Calling-Station-Id = "24-DD-33-44-90-CA" NAS-Port-Type = Wireless-802.11 Connect-Info = "CONNECT 802.11b/g/n" Event-Timestamp = "Sep 23 2019 16:15:14 NZST" Class = 0x436f6e74656e7446696c7465722d4a6e7253747564656e74 Ruckus-SSID = "ABC" Ruckus-BSSID = 0x308dd99d1318 Ruckus-VLAN-ID = 999 Ruckus-SCG-CBlade-IP = 167837962 Ruckus-SCG-DBlade-IP = 167838210 Acct-Input-Packets = 41552 Acct-Output-Packets = 100454 Acct-Input-Octets = 3768396 Acct-Output-Octets = 130474153 Ruckus-Sta-RSSI = 50 Acct-Session-Time = 1500 Proxy-State = 0x3338 Huntgroup-Name = "NEWFortigateRealm" SQL-User-Name = "abcd@abcd.co.nz" Tmp-String-9 = "ai:" Acct-Unique-Session-Id = "58e58a8fd7fbccadf08241d278e4d940" Packet-Original-Timestamp = "Sep 23 2019 16:16:32 NZST" Acct-Delay-Time = 65240 Packet-Transmit-Counter = 2172 (38207) # Executing section preacct from file /etc/freeradius/3.0/sites-enabled/copy-acct-to-home-server (38207) preacct { (38207) [preprocess] = ok (38207) if (request:User-Name =~ /@/){ (38207) if (request:User-Name =~ /@/) -> TRUE (38207) if (request:User-Name =~ /@/) { (38207) if (request:Huntgroup-Name != ''){ (38207) if (request:Huntgroup-Name != '') -> TRUE (38207) if (request:Huntgroup-Name != '') { (38207) update control { (38207) Proxy-To-Realm := request:Huntgroup-Name -> 'NEWFortigateRealm' (38207) } # update control = noop (38207) } # if (request:Huntgroup-Name != '') = noop (38207) } # if (request:User-Name =~ /@/) = noop (38207) } # preacct = ok (38207) # Executing section accounting from file /etc/freeradius/3.0/sites-enabled/copy-acct-to-home-server (38207) accounting { (38207) [ok] = ok (38207) } # accounting = ok (38207) ERROR: Failed to find live home server: Cancelling proxy (38207) WARNING: No home server selected (38207) Clearing existing &reply: attributes (38207) Found Post-Proxy-Type Fail-Accounting (38207) Post-Proxy-Type sub-section not found.
