Re: [SR-Users] please help to configure tls in kamailio for webrtc client like simpl5

Hi Henning and all, I can restart kamailio without error so i think kamailio can access the certs file, am i right? Next, i can check the tls configuration via some command and result like: openssl s_client -connect mydomain.com:4443 result is: CONNECTED(00000003) depth=1 C = US, ST = US, L = HCM, O = mydomain.com, OU = mydomain.com, CN = mydomain.com, emailAddress = thanhtruong217(a)gmail.com verify error:num=19:self signed certificate in certificate chain verify return:0 --- Certificate chain 0 s:/ C=US/ST=US/O=mydomain.com/OU=mydomain.com/CN=mydomain.com/emailAddress=than… i:/ C=US/ST=US/L=HCM/O=mydomain.com/OU=mydomain.com/CN=mydomain.com/emailAddres… 1 s:/ C=US/ST=US/L=HCM/O=mydomain.com/OU=mydomain.com/CN=mydomain.com/emailAddres… i:/ C=US/ST=US/L=HCM/O=mydomain.com/OU=mydomain.com/CN=mydomain.com/emailAddres… --- Server certificate -----BEGIN CERTIFICATE----- xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx IKqnZKfVhfs= -----END CERTIFICATE----- subject=/C=US/ST=US/O=mydomain.com/OU=mydomain.com/CN=mydomain.com/emailAdd… issuer=/C=US/ST=US/L=HCM/O=mydomain.com/OU=mydomain.com/CN=mydomain.com/ema… --- No client certificate CA names sent --- SSL handshake has read 2890 bytes and written 391 bytes --- New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-GCM-SHA384 Server public key is 2048 bit Secure Renegotiation IS supported Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1.2 Cipher : ECDHE-RSA-AES256-GCM-SHA384 Session-ID: 047913A6C905B007C53EB31C51CBED00FDF8BBBBC8ACDA79238314C3AF899776 Session-ID-ctx: Master-Key: 98D20DD5C85389F6BA32F0CADC76789D03BA3534D45F446418120E8358ACE5142FC21C02E0E3E22090A9E5920F8AB835 Key-Arg : None PSK identity: None PSK identity hint: None SRP username: None TLS session ticket lifetime hint: 7200 (seconds) TLS session ticket: 0000 - fa 90 a9 99 5e 02 04 26-ae bf ce f4 05 06 87 e0 ....^..&........ 0010 - d5 a7 f2 74 ac 4a 7d 0b-ae ba 53 a4 89 14 95 52 ...t.J}...S....R 0020 - 68 53 ea 9b e2 1d 23 ae-77 86 6b 74 21 5e 1e 88 hS....#.w.kt!^.. 0030 - 50 75 3f e4 2a 7a 95 63-5a 87 58 b8 ac c1 ae 85 Pu?.*z.cZ.X..... 0040 - d9 73 3d 4d 5f 27 df 37-37 98 02 15 0c 3c 62 96 .s=M_'.77....<b. 0050 - 50 22 cd 2c e9 b0 aa ba-3e e0 9e a5 65 17 35 3f P".,....>...e.5? 0060 - d5 2d 37 4a 99 1a 19 42-aa 63 6a 74 8b fe 70 72 .-7J...B.cjt..pr 0070 - b6 cc 3d e1 b1 f8 da ee-9c 31 db 25 eb 2a 22 f5 ..=......1.%.*". 0080 - 38 87 13 aa 13 c1 4c c4-f9 1a 83 1c 38 a8 a9 15 8.....L.....8... 0090 - c4 70 cd 3f e5 0a 5e 5e-13 a3 13 a7 6d 29 0e 70 .p.?..^^....m).p 00a0 - fc 09 ee df e0 89 f6 48-29 04 1e 69 65 92 f0 e7 .......H)..ie...
