(RADIATOR) Urgent - Radiator does not reply NAS with accounti ng accept respo nse

[Brian CHNG Sing Yong]

Hi Frank

Thanks, appreciate your kindness in sharing with us your experience. I did
use the IgnoreAccountingResponse statement on 3 of my 4 AuthBy RADIUS
statement but I can't apply it on all the 4 because Radiator will end up not
responding at all.

In my environment, I have to forward the acct package to four Radius Host
but my current Radiator configuration behaves in such a way that at least
one Radius Host from the AuthBy RADIUS must reply to the Radiator otherwise
it will not response to NAS which trigger my problem, my requirement is that
even if all Radius host does not response it must still response to NAS with
accounting accept.

AccountingHandled
Forces Radiator to acknowledge Accounting requests, even if the AuthBy
modules for
the Realm would have normally ignored the request. This is useful if you
don't really
want to record Accounting requests, but your NAS keeps retransmitting unless
it gets an
acknowledgment.

Hi Brian-

We run a similar setup for CDMA IS-95 and 1XRTT networks and found the
IgnoreAccountingResponse parameter does what you are describing. Here is the
excerpt from the manual->

6.29.25 IgnoreAccountingResponse
This optional flag causes AuthBy RADIUS to ignore replies to accounting
requests, instead of forwarding them back to the originating host. This can
be used in conjunction with the AccountingHandled flag in a Handler or Realm
(see Section 6.16.10 ) to ensure that every proxied accounting request is
replied to immediately, and the eventual reply from the remote Radius server
is dropped.

Hi 
How can I configure the Radiator Radius to work in such a way that when NAS
send an accounting packet to Radiator, it will reply immediately with
accounting response and then proxy the accounting request to multiple Radius
Host without waiting for accounting response from the Radius Host?
Reason for this configuration:- 
I'm using the Radiator in a GPRS network and it has capability of accessing
to the Internet & WAP via GPRS, but I have one issue here is that the GGSN
or NAS requires the Radius to response with a accounting response before it
will establish a PDP context which will allow the mobile phone to access to
the Internet, but due to the behavior of the Radiator Radius Server, it does
not reply with the accounting response to the NAS until the Radius Host
replies to the Radiator with the response. So when my Radius Host is down,
it affects my GPRS network towards the Internet link.
Regards 
Brian
