Hi All I need to implement Stateless Proxy to translate transport from TLS to TCP.
I have simple routing script: route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if(dst_ip == 10.0.10.11) { log("message received on external interface\n"); force_send_socket(tcp:10.0.20.11:5060); forward("tcp:10.0.20.101:5060"); }; if(dst_ip == 10.0.20.11) { log("message received on internal interface\n"); force_send_socket(tls:10.0.10.11:5061); forward("tls:10.0.10.101:5061"); }; } I'm generating traffic shown on picture below: ---------- ------------------ ----------- | UAC | <-------------> | SL Proxy | <-------------> | UAS | ---------- TLS ------------------ TCP ----------- 10.0.10.101 10.0.10.11 10.0.20.11 10.0.20.101 UAC (10.0.10.101) via TLS to external Proxy interface (10.0.10.11) FORWARD via internal Proxy interface (10.0.20.11) TCP to UAS (10.0.20.101) Everything works fine until destination port is unreachable. When I shutdown UAS (destination port becomes unreachable) Opensips crashes and produces log: Apr 28 08:26:47 hmsa /usr/sbin/opensips[2799]: INFO:core:tls_accept:client did not present a certificate Apr 28 08:26:47 hmsa /usr/sbin/opensips[2799]: ERROR:core:tcp_blocking_connect: poll error: flags 18 Apr 28 08:26:47 hmsa /usr/sbin/opensips[2799]: ERROR:core:tcp_blocking_connect: failed to retrieve SO_ERROR (111) Connection refused Apr 28 08:26:47 hmsa /usr/sbin/opensips[2799]: ERROR:core:tcpconn_connect: tcp_blocking_connect failed Apr 28 08:26:47 hmsa /usr/sbin/opensips[2799]: ERROR:core:tcp_send: connect failed Apr 28 08:26:47 hmsa /usr/sbin/opensips[2799]: ERROR:core:msg_send: tcp_send failed Apr 28 08:26:48 hmsa /usr/sbin/opensips[2803]: CRITICAL:core:receive_fd: EOF on 11 Apr 28 08:26:48 hmsa /usr/sbin/opensips[2794]: INFO:core:handle_sigs: child process 2799 exited by a signal 11 Apr 28 08:26:48 hmsa /usr/sbin/opensips[2794]: INFO:core:handle_sigs: core was generated Apr 28 08:26:48 hmsa /usr/sbin/opensips[2794]: INFO:core:handle_sigs: terminating due to SIGCHLD Apr 28 08:26:48 hmsa /usr/sbin/opensips[2803]: INFO:core:sig_usr: signal 15 received Apr 28 08:26:48 hmsa /usr/sbin/opensips[2796]: INFO:core:sig_usr: signal 15 received Apr 28 08:26:48 hmsa /usr/sbin/opensips[2802]: INFO:core:sig_usr: signal 15 received Apr 28 08:26:48 hmsa /usr/sbin/opensips[2801]: INFO:core:sig_usr: signal 15 received Apr 28 08:26:48 hmsa /usr/sbin/opensips[2800]: INFO:core:sig_usr: signal 15 received Apr 28 08:26:48 hmsa /usr/sbin/opensips[2798]: INFO:core:sig_usr: signal 15 received Apr 28 08:26:48 hmsa /usr/sbin/opensips[2797]: INFO:core:sig_usr: signal 15 received I'm using Opensips version 1.6.3 maintained in EPEL repository [root@hmsa ~]# opensips -V version: opensips 1.6.3-tls (i386/linux) flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, DISABLE_NAGLE, USE_MCAST, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. svnrevision: unknown @(#) $Id: main.c 6169 2009-09-22 12:48:37Z bogdan_iancu $ main.c compiled on 22:39:11 Dec 22 2010 with gcc 4.1.2 I compiled the latest 1.6.4 release and have the same problem. Is it bug ? Please help Regards Adam _______________________________________________ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
