Hi, We have a problem with duplicate sessions on our MikroTik wireless network with FreeRADIUS when OSPF kicks in: Subscription Analysis for user@isp 2010-01-17 up to 2010-01-25 # logged in session time upload download server terminate cause callerid 1 2010-01-23 22:07:31 15 hours 6.9 MB 83.6 MB * 192.168.199.254*:513 - 00:0B:6B:DB:A9:96 2 2010-01-22 22:07:30 18 hours 16.2 MB 451.1 MB * 192.168.208.1*:434 - 00:0B:6B:DB:A9:96 3 2010-01-22 22:07:29 1 days 27.0 MB 0.6 GB 192.168.199.254:434 Session-Timeout 00:0B:6B:DB:A9:96 4 2010-01-21 22:07:27 1 days 4.7 MB 65.0 MB 192.168.199.254:386 Session-Timeout 00:0B:6B:DB:A9:96 5 2010-01-20 22:07:25 1 days 2.9 MB 45.7 MB 192.168.199.254:331 Session-Timeout 00:0B:6B:DB:A9:96 6 2010-01-19 22:07:23 2 hours 171.3 KB 1.4 MB 192.168.208.1:290 - 00:0B:6B:DB:A9:96 7 2010-01-19 22:07:23 1 days 2.9 MB 24.5 MB 192.168.199.254:290 Session-Timeout 00:0B:6B:DB:A9:96 8 2010-01-18 22:07:20 1 days, 1 seconds 3.8 MB 66.2 MB 192.168.199.254:207 Session-Timeout 00:0B:6B:DB:A9:96 9 2010-01-17 22:07:15 1 days 1.5 MB 10.0 MB 192.168.199.254:166 Session-Timeout 00:0B:6B:DB:A9:96 10 2010-01-17 22:07:15 0 seconds 0.0 KB 0.0 KB 192.168.208.1:166 - 00:0B:6B:DB:A9:96 High site 1 is 192.168.199.254 and high site 2 is 192.168.208.1. As you can see it looks like FreeRADIUS counts the extra data on the dropped connection as well. The only suggestion I have received so far is to use a product called SMRadius (http://www.smradius.org/tiki-index.php?page=Features) that apparently merges duplicate sessions. But my FreeRadius installation is 7 years old and I don't want to change to another product. We are using FreeRADIUS Version 1.1.7, for host x86_64-pc-linux-gnu (Ubuntu 8.04 64-bit). mysql Ver 14.12 Distrib 5.0.51a, for debian-linux-gnu (x86_64) using readline 5.2 Apart from that we have a pretty stock standard default installation. I have heard about some other people with large MikroTik networks and OSPF and FreeRADIUS that they are having the same problem. I have also described this problem on the MikroTik forum: http://forum.mikrotik.com/viewtopic.php?f=2&t=38620 please assist urgently, this problem is leading to some difficult client service inquiries. -------- Eugene van der Merwe
