Re: [reSIProcate-users] reTurn TestAsyncClient TLS mode fail

Scott, 

Thank you for your help! 
I'm wondering why these two TURN servers behave differently? is there any specification to follow?

Hi Tom,

Last time I checked TLS works fine in reTurn server and client APIs.  Your wireshark trace shows a SSL/TLS Hello being sent to your server, then there is no response from the server.  We do not support the turnserver (http://turnserver.sourceforge.net/) project here.  You could try using the reTurn TURN server instead.

Hello,

 

I have successfully tested TURN client reTurn/client/test/TestAsyncClient.cxx in UDP mode, however, somehow, the TLS mode always fails. From the shell screen of turnserver, I can see that the TCP/TLS connection has been established successfully, so the cert file (the ca.perm in the same directory) seems to be confirmed ok:

 

0: IPv4. TCP listener opened on : 10.113.54.60:3478

0: IPv4. TCP listener opened on : 10.113.54.60:3479

18: IPv4. tcp or tls connected to: 10.113.54.61:51575

 

But then nothing happens, the onConnectSuccess or Failure events of the TestAsyncClient.cxx are not observed. I am wondering why? I am not sure if my TURN server was started correctly? Or TestAsyncClient.cxx needs some extra work? Can someone help me to figure out?

 

My setup is like this:

TestAsyncClient is running at 10.113.54.61

turnserver at 10.113.54.60

UDP echo server at 10.113.54.57 (should I use a TCP echo server as test peer instead?)

 

Turn Server Start script:

turnserver -v --log-file /tmp/turn.log -f --min-port=32355 --max-port=65535 --no-stun=1 -r ip:port -c /etc/turnserver/turnserver.conf --cert /home/tom/workspace/resiprocate-1.9.10/reTurn/client/test/ca.pem

 

Turn Client Start script:

#TestAsyncClient 10.113.54.60 3479 10.113.54.61

INFO | 20000705-060733.809 |  | RESIP:DNS | 1075036160 | DnsUtil.cxx:233 | Local IP address for  is 169.254.6.91

INFO | 20000705-060733.813 |  | RESIP:TEST | 1075036160 | TestAsyncClient.cxx:279 | Using 10.113.54.61 as local IP address.

 

Attached is the trace captured on the TURN server, TCP packet #546 ~ 552 are for communication establishment between TURN server (10.113.54.60) and client (10.113.54.61). I used “ip.addr==10.113.54.61” as packet filter for Wireshark.
