Re: [SR-Users] Kamailio when acting as client doesnt send SNI in client hello handshake message

Hi , I further went thru the logs of kamailio, and i see the below happening. tls [tls_server.c:169]: tls_get_connect_server_name[]: xavp with outbound server name not found tls [tls_server.c:152]: tls_get_connect_server_id[]: found xavp with outbound server id: btip.176.com Its strange its able to find the client profile based on server_id , but not able to find using the server_name In tls_complete_init( ) if (c->flags & F_CONN_PASSIVE) { state=S_TLS_ACCEPTING; dom = tls_lookup_cfg(cfg, TLS_DOMAIN_SRV, &c->rcv.dst_ip, c->rcv.dst_port, 0, 0); } else { state=S_TLS_CONNECTING; sname = tls_get_connect_server_name(); srvid = tls_get_connect_server_id(); dom = tls_lookup_cfg(cfg, TLS_DOMAIN_CLI, &c->rcv.dst_ip, c->rcv.dst_port, sname, srvid); } Am acting as client, so it will hit the else part the call to sname = tls_get_connect_server_name(); //failed with below logs tls [tls_server.c:169]: tls_get_connect_server_name[]: xavp with outbound server name not found the call to srvid = tls_get_connect_server_id(); // success with below logs tls [tls_server.c:152]: tls_get_connect_server_id[]: found xavp with outbound server id: btip.176.com And futher down in the function : as sname is NULL, it is not setting the server name extension in client hello message. #ifndef OPENSSL_NO_TLSEXT if (sname!=NULL) { if(!SSL_set_tlsext_host_name(data->ssl, sname->s)) { if (data->ssl) SSL_free(data->ssl); if (data->rwbio) BIO_free(data->rwbio); goto error; } LM_DBG("outbound TLS server name set to: %s\n", sname->s); } #endif Am i missing anything here w.r.t configuration ? or is it a bug ? which has been fixed in later versions ? Please help !! Regards, Mahesh.B On Thu, Dec 19, 2019 at 5:53 PM mahesh b <mahesh.b.2487(a)gmail.com> wrote:
