Hello,

 

May I have any comments on the issue? 

It blocks the application for monthes.

 

Thanks,

Kevin

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

Thanks,

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

Cheers,
Daniel



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

0(27429) ERROR: nathelper [nathelper.c:2492]: proxy <udp:210.13.124.15:7722> does not respond, disable it

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