We have just upgraded to FreeRADIUS 2.1.6, but unfortunately the problem persists:

Server1/: total 1008236 -rw------- 1 root root 714751062 Jul 29 11:53 detail-20090729 -rw------- 1 root root 316653344 Jul 29 07:29 detail.work <= stuck!

We got sometimes the following message for Server2:

Thu Jul 23 15:00:45 2009 : Proxy: No outstanding request was found for proxy reply from home server <Server2 IP address> port 1813 - ID 142 And several messages for Server1:

Wed Jul 29 11:36:53 2009 : Error: Rejecting request 3993531 due to lack of any response from home server <Server1 IP address> port 1813 Wed Jul 29 11:36:53 2009 : Error: PROXY: Marking home server <Server1 IP address> port 1813 as zombie (it looks like it is dead). Wed Jul 29 11:37:28 2009 : Info: Suspicious proxy state... continuing Wed Jul 29 11:37:30 2009 : Error: Rejecting request 3998634 due to lack of any response from home server <Server1 IP address> port 1813 <...>

In an attempt to force the revival of Server1, we scheduled the execution of the following command every minute:

radmin -e "set home_server state <Server1 IP address> 1813 alive"

Ugh, don't do that.

But still, it seems to stuck ... I checked with "tcpdump port 1813 and host <Server1 IP address>" that even though the details.work for Server1 is freezed, FreeRADIUS is sending accounting requests to Server1 and it is receiving accounting responses.

# tcpdump port 1813 and host <Server1 IP address> tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 11:39:27.667255 IP <FreeRADIUS IP address>.1814 > Server1.radius-acct: RADIUS, Accounting Request (4), id: 0x0c length: 202 11:39:27.675969 IP Server1.radius-acct > <FreeRADIUS IP address>.1814: RADIUS, Accounting Response (5), id: 0x0c length: 20 <...>

Is there a firewall blocking requests? Server1 is sending responses but they are not reaching the proxy. Ivan Kalik Kalik Informatika ISP
