Hi, I have enabled tls parameters as follows: in kamailio.cfg listen = tls:<IP>:<PORT> in tls.cfg [server:<IP>:<PORT>] method = TLSv1 verify_certificate = no require_certificate = no private_key = /usr/local/etc/kamailio/kamailio-selfsigned.key certificate = /usr/local/etc/kamailio/kamailio-selfsigned.pem Now if i try to connect to this interface using openssl s_client, it does connects, but now server certificate is sent from kamailio. kamailio log shows this : <core> [ip_addr.c:247]: tcpconn_new: new tcp connection: <CLIENT IP> <core> [tcp_main.c:1089]: tcpconn_new: on port 40727, type 3 <core> [tcp_main.c:1400]: tcpconn_add: hashes: 2614:2652:2494, 2 <core> [io_wait.h:390]: DBG: io_watch_add(0x82535e0, 23, 2, 0xb5701580), fd_no=11 <core> [io_wait.h:617]: DBG: io_watch_del (0x82535e0, 23, -1, 0x0) fd_no=12 called <core> [tcp_main.c:4296]: tcp: DBG: sending to child, events 1 <core> [tcp_main.c:3963]: WARNING: send2child: no free tcp receiver, connection passed to the least busy one (3289651) <core> [tcp_main.c:3967]: selected tcp worker 0 0(8) for activity on [tls:<IP>:<PORT>], 0xb5701580 <core> [tcp_main.c:3576]: BUG: handle_ser_child: fd -1 for 0 (pid 2491) I'm using kamailio from git. its updated to the latest. Thanks in advance.

Use wireshark to analyze the TLS handshake regards klaus On 09.07.2012 13:27, Aft nix wrote: _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

No. both are 4. (udp and tls ) I have downgraded the lab machine to do some testing. so i can't give kamctl ps of the faulty installation at this moment. kamailio-3.2.x is deployed in our production servers, and it worked flawlessly. this is the output of kamctl ps from a 3.2.x. it uses the same config file as i was using with git master branch.

On the side note similar issue was reported by a guy earlier this year in this list which went unnoticed. here is the link to that mail : http://lists.sip-router.org/pipermail/sr-users/2012-April/072683.html His issue seems similar to me. Cheers
