This is not the forum for "Quintum only" questions.

You can find user information on Quintum's website:
http://www.quintum.com/support/products

You have an A800 Gen1 box, from the CLI enter "disp
v", look at the line "Feature Bit Status: +PS/+RB/-ER"
and verify that "+RB" is shown.  This will verify that
you have the proper hardware for Reverse Battery.

To set the config from the CLI:
- Go to "config pstntg1#"
- enter "cassig 5" to set the interface for RevBattery

As Stewart Nelson has remarked some gnugk version has nat traversal problem
... for this reason I had to use the 2.0.9 version and this network
configuration in order to solve a problem like your one (gnugk behind nat
and with 2 intefaces say 192.168.0.1 and 192.168.1.1) :

Like you can see I had to insert a new gnugk between the the first gnugk an=
d
the adsl router (the gatekeeper are configured like neighboors), this
because even the 2.0.x version had some trouble handling the internet
address  (probably a routing problem, or this is what I suppose since with
only one interface the internet address is handled without any problem).
with this solution all is working correctly .... :).
Now, I didn't tried the latest version so I don't know if they solve this
problem but, if you are using it, probably not :(.
Merry Christmas and Happy new Year!!!

I'm disappointed that none of the core developers had any comments whatsoever. Since there doesn't seem to be any viable solution I was forced to optimize it instead. It now comfortably handles over 300+ calls per second without stressing the cpu.

Hi Bluce I had the same problem and I was advised two options by a friend of mine : 1) Quick and dirty method is to block the IP in IPChains of your system, but that wont relieve the system fully as request would still be coming but now your system would be dropping the request from that IP. 2) Other method is to get that IP blocked @ gateway, that wud completely relieve ur system from that IP Hope it helps

bluce ree <bluceree@xxxxxxxxx> wrote:

I tried reducing the value of "ListenQueueLength" as far down as 1 with no positive effect. Calls coming in continue to slow the GK to almost a complete halt as the queue flushes at rates of 100 - 200 calls per second. Faster CPU doesn't help (quad opteron).

Is there any way to control the incoming rate of calls? In the config file i see the following parameter:

 ListenQueueLength=1024

 If I reduce that number to, say, 50, would that help?

 Would reducing that number cause any other issues I should consider?

Is there another way I can limit the incoming connection queue to prevent being slammed?

<DIV>I'm disappointed that none of the core developers had any comments whatsoever. Since there doesn't seem to be any viable solution I was forced to optimize it instead. It now comfortably handles over 300+ calls per second without stressing the cpu.</DIV> <DIV><BR><BR><B><I>bluce ree &lt;bluceree@xxxxxxxxx&gt;</I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <DIV>Does anybody have anything to suggest as a solution to control the rate of calls per second?</DIV> <DIV>&nbsp;</DIV> <DIV><BR><BR><B><I>bluce ree &lt;bluceree@xxxxxxxxx&gt;</I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <DIV>&nbsp;</DIV> <DIV>Thanks for the reply but completely blocking the customer isn't what I want to do.

when a certain number of calls are in queue that have not yet undergone translation or some other means to control rate of call flow.</DIV> <DIV><BR>&nbsp;</DIV> <DIV> <TABLE width="100%" border=0> <TBODY> <TR> <TD noWrap bgColor=#dddddd>From: Muhammad Asif Ali &lt;m@xxxxx&gt; <BR><A href="http://sourceforge.net/mailarchive/message.php?msg_id=14202588";><B><IMG height=12 alt="" src="http://images.sourceforge.net/images/msg.gif"; width=10><FONT color=#0033cc> Re: Call slamming</FONT></B></A> &nbsp; <BR>2005-12-15 23:20 </TD></TR> <TR> <TD><PRE> Hi Bluce I had the same problem and I was advised two options by a friend of mine : 1) Quick and dirty method is to block the IP in IPChains of your system, but that wont relieve the system fully as request would still be coming but now your system would be dropping the request from that IP. 2) Other method is to get that IP blocked @ gateway, that wud completely relieve ur system from that IP Hope it helps </PRE></TD></TR></TBODY></TABLE><BR><B><I>bluce ree &lt;bluceree@xxxxxxxxx&gt;</I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <DIV>&nbsp;</DIV> <DIV>Anyone have any thoughts or suggestions on how to limit the rate of incoming calls per second? </DIV> <DIV>&nbsp;</DIV> <DIV>I tried reducing the value of "ListenQueueLength" as far down as 1 with no positive effect.
