Try with the latest cvs, it should fix most of the warnings.
BTW: this warnings are gcc 3.4 specific, I haven't got them with other
versions (2.95, 3.0, 3.2, 3.3, 3.5).
The core dump is somewhere in the radius library, not in ser (ser
crashes because the radius lib crashes). Try updating your
radiusclient-ng library.

Hello Everybody,
I am using ser with mysql to authenticate my users, well, i'm trying to use, i'm having an erro message when I start it. What I exactly did was: start up ser (without mysql.so modulo at ser.cfg), and started mysql database with just one table ... obviously when I try to execute "# ser_mysql.sh create", this returns me the following error because I don't have the mysql.so configured in the ser.cfg
"ERROR 1064 (42000) at line 7: You have an error inyour SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'BY '47serro11'' at line 1"
The problem is that when I configure the mysql.so at ser.cfg with the line '"lodmodule "/usr/local/lib/ser/modules/mysql.so"' and start again the ser server, the following error appears:
"ERROR: bad config file (1 errors)"
Even if you could create the mysql tables with the ser_mysql.sh I wouldn't be able to run ser with the mysql support. What am i doing wrong ?

Hi
I have set up SER
all the clients to the server are NATed
i can call out to users on other SIP providers fine... but i can not
call beween my own users!
firewalls doing the NAT on both clients are SIP capable (sonicwalls).
is there any way to fix this?

Chris,
I'm using a pre compiled version 0.8.14 ... there's is no make point to make all & make install the software, maybe because I downloaded the wrong version, or a very old version... I've tried to download it again from the above links listed in the site:
ftp://ftp.berlios.de/pub/ser/latest/
ftp://ftp.berlios.de/pub/ser/
But it doesn't download, maybe the link is down ...
My Mysql is working fine (version 4.0.22) but I'm a little bit confused about the version to make all & make install ser. Could you send me you ser version or the program itself if it's a different one ?
Thanks in Advance

I had the same symptoms which may be the same cause.
The makefile excludes mysql so mysql.so does not get built/installed.
I removed the exclusion, made all + made install and it was cured.
(Though curiously I had to reboot the linux first to clear mysql which seem
to be hung up.)

Hi,
I am thinking about having more NAT test on a sip packet. Just want to find
out if it is useful.
I run into some situations that some 'smart' UAs try to detect its external
IP and put the external IP address into the sip packet. Depending on the
network and NAT firewall setup, it may or may not set the right external IP
and port in the packet. If it is not, but pretends to be on the public
internet, then there is most likely a one-way voice or no voice issue. I'd
like to be able to detect and force it to use a nat proxy. By checking these
packets, I found that the only trace is the private IP address in the
call-id header field. It will be useful to check if a RFC1918 address is
used in the call-id. I understand that it is not a thorough test for NAT,
well, just like any other NAT test.
Can someone please comment if it is a good test?
Thanks,
Richard
Hi
Well first all, I now seem to have a ser 0.8.14 installed and running and
showing all the “superficial” signs of working!
So I give my thanks to all of you who have worked so hard and so well on ser
to get this server to its current status.
I now seek to checking out the ser more fully and in particular all of its
features.
I have seen the individual examples function by function in CVS.
However I seek to find an integrated single example containing of all the
ser features.
In particular I seek an example that is known to work stably and properly
with 0.8.14.
In other words I seek to avoid having to rediscover the pitfalls that I see
others have fallen into from time to time when I trawl back through the
seruser archives…
Is there such a “known to work with .14” integrated example of all the
stable .14 working features?
Would it be a good idea to keep such a master example in CVS?
Thanks for your help.
Chris

Hi,
I would like to know do I need to install another redirect server
besides ser? You know, from the ser doc, it says that it provides proxy
and registrar functions only.
If yes, where could I get a redirect server software?
Thank you.
