Unsupported transport tcp! running echotest alongside apache2

[Pete Andrews]

Hello all!

i'm a bit confused as to what i'm seeing here with a janus server running alongside  apache2 on ubuntu 14.04, and i'm wondering if anyone can help. I have followed and performed the build/installation guide for Janus without problems, and after starting the server, i'm attempting to load the echotest.html page hosted on the same machine with Chrome. I'm wondering what the "Unsupported transport tcp!" message is all about. What is that an indication of? Here's the NAT related section of my config file:

[nat]
public_ip = 10.0.0.43
;stun_server = stun.voip.eutelia.it
;stun_port = 3478
nice_debug = false

and here's the output of the server:

msuv@msuv-HP-ProBook-450-G1:/opt/janus/bin$ ./janus

I'm assuming i've missed something in the configuration of the server ....
i can load the echotest.html demo on this machine from the official meetecho website.. so i know the test will work with the browser.

That's just a warning. We don't handle TCP ICE candidates and we ignore them, but that's ok as they're not needed.

ok - good to know.
i'll open the trace up more and see if i can't get some indication as to why i get no video/audio - just a black box for the remote stream.

thanks for the info!

only thing I see out of the ordinary is the STUN errors around line 1452.
Again... any indication in this log as to why echotest would fail to show the remote stream?

The server seems to be installed behind a NAT (it has a private 10.x.x.x) address, but you didn't configure a STUN server for Janus to use. As a result, Janus is sending candidates that the browsers can't communicate with (private address), ICE fails, and nothing works. Check the configuration file on how to add a STUN server there.

OK - got it sorted.
the solution was in a post a little while back... this is what i did:

---------------------------------------------------------------------------------------

Open dtls.c and just after line 135, add : SSL_CTX_set_read_ahead(ssl_ctx,1) ;

make, make install and try. It works very well for me. 
related to https://github.com/meetecho/janus-gateway/issues/132 and maybe https://github.com/meetecho/janus-gateway/issues/134

------------------------------------------------------------------------------------------

once i made that change in dtls.c and rebuilt, it worked.

thanks!

You should actually not need to do that manually, if you have the latest code. That line has already been added to the version we have on github. Is your version of the code not up-to-date?
