[Serusers] ser+nathelper+rtpproxy / can't read reply from a RTP proxy

Hi, I have just installed ser this week. It's very cool and happy to find FreeBSD port of it. Anyway, I have rtp proxy connection problem of ser+nathelper+rtpproxy system. To refer console log, it seems no communication between ser and rtpproxy. Does anyone know how to fix it? ------ gw# /usr/local/sbin/ser -D -E -Listening on : : stateless - initializing Maxfwd module- initializing 0(47772) mod_init(): Database connection opened successfuly textops - initializing 0(0) INFO: udp_init: SO_RCVBUF is initially 41600 0(0) INFO: udp_init: SO_RCVBUF is finally 231936 0(0) WARNING: using only the first listen address (no fork) 2(47774) INFO: fifo process starting: 47774 1(47773) ERROR: send_rtpp_command: can't read reply from a RTP proxy 1(47773) 2(47774) WARNING: rtpp_test: can't get version of the RTP proxy ERROR: send_rtpp_command: can't read reply from a RTP proxy 1(47773) 2(47774) WARNING: rtpp_test: support for RTP proxyhas been disabled temporarily ------ Here is my environmnet: OS : FreeBSD 4.10-RELEASE-p2 ser version: ser 0.8.14-2 (i386/freebsd) get stable version from CVS, since port version is still 0.8.12... nathelper : get from CVS 14-Oct-2004 I run ser and rtpporoxy as root user to avoid permission issue. and /var/run looks no problem. srwxr-xr-x 1 root wheel 0 Oct 15 14:53 rtpproxy.sock ---- # ----------- global configuration parameters ------------------------ debug=3 # debug level (cmd line: -dddddddddd) #fork=yes #log_stderror=no # (cmd line: -E) ----- /* Uncomment these lines to enter debugging mode */ fork=no log_stderror=yes check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) port=5060 children=4 fifo="/tmp/ser_fifo" #fifo_mode=0666 ### temporary for ser to write/read /var/run/rtpproxy.sock #uid="nobody" #gid="nobody" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/local/lib/ser/modules/mysql.so" loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" loadmodule "/usr/local/lib/ser/modules/textops.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" # !!
