Hi,
We have deployed many Cisco ATAs behind NAT devices. In order to keep the NAT session
binding alive, we enabled a feature on the ATAs that basically send a small dummy packet
to SER every 90 seconds. Everything works great. The question is, how can I suppress the
WARNING/ERRORS that these dummy packets present to the SYSLOG? Is there a simple way to
do this in the ser.cfg file?
These are the SYSLOG messages:
May 1 09:20:58 maui /usr/sbin/ser[23389]: WARNING: upstream bug - 0-terminated packet
May 1 09:20:58 maui /usr/sbin/ser[23389]: ERROR: parse_first_line: message too short: 3
May 1 09:20:58 maui /usr/sbin/ser[23389]: ERROR:parse_first_line: bad message
May 1 09:20:58 maui /usr/sbin/ser[23389]: ERROR: parse_msg: message=<>
May 1 09:20:58 maui /usr/sbin/ser[23389]: ERROR: receive_msg: parse_msg failed
Thanks,
Ricardo

Out of curiosity: how did you exactly make the ATAs to send the keep-alives for you?
Did you write your own image?

Send some SIP keep-alive messages. SER drops non-SIP messages. If you are sorry
about too large messages, you could generate such which include only first line
and topmost via (elements which are always checked) and include a method check
in script, which drops them.

We have deployed ATAs that come with images 2.14 and 2.15. Those images
have a parameter called NatTimer (and NatServer). The manual describes
NatTimer as:
NatTimer
Description
This parameter allows you to specify a retransmission interval for sending a
dummy packet to NatServer.
The interval is in seconds and is specified in bits 0-11 of this parameter.
The upper 20 bits are reserved
and should be set to 0.
Value Type
Bitmap
Default
0, which means that no dummy packets will be sent to the NatServer.
-----------
An ngrep of the dummy packet shows as:
U 67.35.13.22:5060 -> 200.75.73.22:5060
00 00 00 00 ....
So it is basically an empty packet and it causes SER to generate those
ERRORS in the SYSLOG. I do not mind that those errors ocurr, but it is
causing our SYSLOG files to become full of this useless information. I
guess an alternative for me would be to simply eliminate the source code
that puts the ERRORs in the SYSLOG but I was looking for a simpler way.
Thanks,
Ricardo

Hello,
it is only possible to disable these warnings if you disable logging
almost completely (which is probably not what you want). Did you compile
the server or use some of the packages ? If you know how to compile it I
can tell you how to disable it in the sources easily.

Hi Jan,
I looked though the source code and commented out the places where I
identified those particular LOG generating entries. I then generated the
new "ser" executable using a plain "make". The problem is that the
new
"ser" does not look for the config in /etc/ser/ser.cfg. I have to give it
the path by starting it with "ser -f /etc/ser/ser.cfg". What do I need to
do for it to compile so that it defaults to look at /etc/ser/ser.cfg?
Thanks,

Hello Ricardo,
use cfg-target="/etc/ser/" when doing make all, i.e.:
make all cfg-target="/etc/ser/"
