Hello,
please try the attached patch (is for devel but should apply on 1.3.2,
if no, let me know and I send you another). Similar issue was reported
to me some time ago, started to investigate but at some point I forgot
about. I think you face the same case: somewhere in the script you do an
IP comparison (by src_ip or so) and you have the IP address in between
quotes. The patch fixed the reverse dns in this case if rev_dns=no. I
will look more into it to find a better solution -- detecting if the
value is an IP address and avoid DNS lookup, a.s.o, for IP comparisons.
Let me know the results.
Cheers,
Daniel

Here is why I ask:
[root@proxy2 openser]# netstat -su
Udp:
159293 packets received
2016 packets to unknown port received.
153899 packet receive errors
185342 packets sent
On my proxies, as traffic levels increase, I start getting udp errors, which
I think is pretty much a udp buffer overflow. Once it overflows, that proxy
is toast until traffic levels die down. I have a pretty basic config, but I
can't seem to handle more than 4 or 5 new calls per second. I would expect
to be able to do a lot more than that. So I was trying to make sure that no
unnecessary udp traffic was going in or out.
The server has two Dual Core Opteron processors, 4 Gb of RAM, running CentOS
5 x86_64.
Any suggestions are appreciated... and I'll happily pay for consulting if
someone wants to look into it.
Michael

Subject: [OpenSER-Users] Openser 1.3.2 rev_dns=no
In my openser.cfg (running 1.3.2), I have:
dns=no
rev_dns=no
but a packet capture shows OpenSER doing a reverse DNS lookup on my
provider's proxy IP address with every invite. Are those lines no longer
supported? I tried starting OpenSER with -R, but same behavior.
