Hi, We have a problem with duplicate sessions on our MikroTik wireless network with FreeRADIUS when OSPF kicks in:

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
