Hi Alan,<br><br>The main reason my initial checking was with tcpdump was to identify what the packets were doing.<br><br>ACCT request IN from LNS - check<br>ACCT request OUT to downstream RADIUS - no<br><br>So the problem is not due to the downstream RADIUS failing to respond at all. (ie genuinely/obviously dead)<br>
<br>Overnight I upgraded to 2.1.8, and now the behavior has changed, slightly.<br><br>Freeradius is complaining in the logs, but now it looks like enough back-n-forth is happening that my LNS doesn't lose its mind any more.<br>
<br>Freeradius is deciding that my accounting proxy destination 'looks like it is dead'.<br><br>Tue Feb 16 07:45:32 2010 : Proxy: Marking home server {{radius-ip}} port 1813 as zombie (it looks like it is dead).<br>
<br>I'm not entirely sure why, though. TCPDUMP shows a stream of accounting requests being proxied to that server, and being received from that server, while at the same time freeradius continues to log 'looks like it is dead' messages.<br>
<br>Also, status check (via request) succeeds, naturally, given that its not the auth proxy that freeradius is complaining about.<br>(single downstream RADIUS configured as auth+acct)<br><br><br>Thanks,<br>Phil P<br><br>

</div> The logs from the server?<br>
<br>
I don't understand why you're looking at tcpdump, and not the<br>
FreeRADIUS logs.<br>
<br>
In 2.1.7, you can also use "raddebug" to get the debug logs from a<br>
running server.<br>
