Subject: Double radius accounting
Date: Wed, 20 Nov 2013 21:45:23 +0000 [thread overview]
Message-ID: <1683678123.142102.1384983923718.JavaMail.zimbra@yetopen.it> (raw)
Hi.
I've configured a PPTP server with FreeRadius authentication, and I'm having some problems with authorization: in the accounting table I see a double accounting session for every client.
The two sessions are almost identical, they differ by just one (or zero) second in the start time.
My clients are (mostly) DDWRT routers connecting to a Debian server with pptp version 1.3.4-3 and pppd 2.4.5.
I tried enabling dump in ppp options and syslog shows the following:

Is it normal to see the radius plugin initializaion TWICE?
Why pppd says it got the radius plugin from command line while it has not? I already did some debugging with poptop mailing list but we didn't figure out anything on that side. We also checked the command parameters and this is the output (don't mind the different IP, it was another process than the above):

Why does it write double accounting records? What can I check?
Thanks!
