all recent branches.
Cheers,

Daniel, thanks.
I applied the patch and recompiled, and the reverse DNS lookup no longer
occurs. I will load test and let you know how this affects performance.

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.
