New subject: Kamailio 3.0 cann't access the RTPProxy

18 Aug 2010

      Hello,
apart of the email with logs, or private data that was required, please
continue the discussion on public mailing list.
I need some time to check the logs, the first inconvenience is the rar
archive, a zip or tgz is much better -- not a fan of installing binaries
from unknown companies on mac os x, going to get unrar from macports.
Then solaris is not an OS i have at hand nor use frequently, so need to
read about. It is also why using mailing list keeps you in touch with
others that can help.
Cheers,
Daniel

Hi Daniel,
Does the logs have any hint for what's cause of the issue? I didn't
include the user list in the previous email since logs have the actual
IP info.
Thanks in advance!
Best Regard
Kevin

Hi Daniel,
Attached are the two kamailio logs,
unix_socket_log --- run rtp proxy wth -s unix:/tmp/rtpproxy.sock
udp_rtpproxy_log --- run rtp proxy with -s udp:*:7722
Please help to check what's wrong with it.
Thanks,
Kevin

Hello,
please send full log at startup, your snippets include just few lines
per process, being mixed from different processes.
Cheers,
Daniel

        Hi Daniel,

        What does the log below means? Does it mean nathelper has
        issue to send the request to RTP proxy first or nathelper
        doesn't receive a response after sending a request to the
        rtp proxy?
        0(27429) ERROR: nathelper [nathelper.c:2457]: can't send
        command to a RTP proxy

    this error is printed when write to socket fails. Do you have
    any firewall running on the system? Is the user under which
    kamailio runs allowed to write to sockets?

        There's no firewall on the system, and I run the kamailio
        as root,
        root 26310 1 0 02:24:19 ? 0:00
        /usr/local/kamailio-3.0.2/sbin/kamailio -f
        /usr/local/kamailio-3.0.2/etc/kamail

        You can edit module_k/nathelper/nathelper.c and replace
        the line 2457 with:

        LM_ERR("can't send command to a RTP proxy (%s/%d)\n",
        strerror(errno), errno);

        Recompile and reinstall. Hopefully will get more hints
        about what happens.

    Here is the error message after the change:
    2(26312) ERROR: nathelper [nathelper.c:2457]: can't send
    command to a RTP proxy(Invalid argument/22)
    2(26312) ERROR: nathelper [nathelper.c:2492]: proxy
    <udp:210.13.124.15:7722> does not respond, disable it
    2(26312) ERROR: nathelper [nathelper.c:3144]: no available proxies
    what could be the cause?

hmm, invalid argurment ... try with this line:

LM_ERR("can't send command to a RTP proxy (%s/%d) [sock %d (%d),
vcnt %d]\n",
strerror(errno), errno, rtpp_socks[node->idx], node->idx, vcnt);

maybe will give some hints about which value is invalid.

Here's the log after the change:
4(14415) ERROR: nathelper [nathelper.c:2457]: can't send command
to a RTP proxy (Invalid argument/22) [sock 7 (0), vcnt 18]
4(14415) ERROR: nathelper [nathelper.c:2492]: proxy
<udp:210.13.x.y:7722> does not respond, disable it
4(14415) ERROR: nathelper [nathelper.c:3144]: no available proxies

Can you try as well with an unix file socket:

modparam("nathelper", "rtpproxy_sock", "unix:/tmp/rtpproxy.sock")

then start rtpproxy with -s unix:/tmp/rtpproxy.sock

4(17530) INFO: nathelper [nathelper.c:2369]: rtp proxy
<unix:/tmp/rtpproxy.sock> found, support for it re-enabled
3(17529) ERROR: nathelper [nathelper.c:2429]: can't send command
to a RTP proxy
3(17529) ERROR: nathelper [nathelper.c:2492]: proxy
<unix:/tmp/rtpproxy.sock> does not respond, disable it
3(17529) ERROR: nathelper [nathelper.c:3144]: no available proxies

Thanks,
Kevin

I have no solaris (sparc) to try myself...

Cheers,
Daniel

    Test env:
    UA1 (Behind NAT) --------> Kamailio & RTPproxy (Public IP)
    --------->UA2 (Public IP)

        There's no problem for the resource(CPU, mem etc.) on the
        server, the load is very low.

        Thanks in advance!
