[SR-Users] Kamailio 3.0 cann't access the RTPProxy

Tue Jul 27 16:21:21 CEST 2010

Hi Daniel,

I use the rtpproxy 1.2.1. And seems loopback interface cann't be caputred on Solaris. I have tried the rtpproxy on other interface and tried the caputre, however didn't see anything on port 7722. 

One more thing like to mention is that I got some error like below:

if gcc -DHAVE_CONFIG_H -I. -I. -I.    -std=gnu99 -Wall -Wno-uninitialized -g -O2 -MT rtpp_notify.o -MD -MP -MF ".deps/rtpp_notify.Tpo" -c -o rtpp_notify.o rtpp_notify.c; \
        then mv -f ".deps/rtpp_notify.Tpo" ".deps/rtpp_notify.Po"; else rm -f ".deps/rtpp_notify.Tpo"; exit 1; fi
rtpp_notify.c: In function `reconnect_timeout_handler':
rtpp_notify.c:240: error: `AF_LOCAL' undeclared (first use in this function)
rtpp_notify.c:240: error: (Each undeclared identifier is reported only once
rtpp_notify.c:240: error: for each function it appears in.)
gmake[1]: *** [rtpp_notify.o] Error 1
gmake[1]: Leaving directory `/opt/csw/src/rtpproxy'
gmake: *** [all] Error 2

I search on internet and added the following in the beginnng of the rtpp_notify.c, and the make gets through. Not sure if this change has any issue.

#ifndef AF_LOCAL
#define AF_LOCAL AF_UNIX
#endif

Thanks,

Kevin

Hello,

can you sniff the loopback interface for communication on port 7722 (i.e., using ngrep/wireshark, etc...)?

What is the version of rtppproxy do you have?

Cheers,
Daniel

Hi All,

 I have the kamailio configed as below on Solaris 10 (Sparc):

# ----- nathelper -----
#!ifdef WITH_NAT
modparam("nathelper", "rtpproxy_sock", "udp:127.0.0.1:7722")
modparam("nathelper", "natping_interval", 30)
modparam("nathelper", "ping_nated_only", 1)
modparam("nathelper", "sipping_bflag", 7)
modparam("nathelper", "sipping_from", "sip:pinger at kamailio.org")
modparam("registrar|nathelper", "received_avp", "$avp(i:80)")
modparam("usrloc", "nat_bflag", 6)
#!endif

and rtpproxy is started as 
AppSer01:ipunity@/opt/ipunity$ ps -ef |grep rtp
 ipunity  4687     1   0 12:58:20 ?           0:00 /usr/local/bin/rtpproxy -l 210.xx.xx.xx -s udp:localhost:7722

AppSer01:ipunity@/opt/ipunity$ netstat -an |grep 7722

127.0.0.1.41519      127.0.0.1.7722       Connected

However, kamailio is not able to connect the rtpporxy,

Any helps are appreciated.
