stun

I am trying to figure out how to test whether a STUN/TURN server is alive and properly responding to connections. Ideally this test would be performed from an external machine, just in case the STUN/TURN machine is down for this case should also be reported by the connectivity test. Has anyone looked into this case in the past? What solutions would be recommended? Edit: A nice implementation in github.io taken from comment to another answer( choose "relay" in IceTransports value): Test TURN Server following Benjamin Trent's advice, I wrote the below code to test TURN server's connectivity,

I have just downloaded a video chat project. It uses a STUN server and specifies the URL stun:23.21.150.121 . How can I use my own server instead of the STUN server? What do I have to enter instead of this URL? Actually there is no need to setup your own STUN or TURN servers, because there are a lot of public/semipublic servers. STUN from Google not always works very well. This is my latest verified list (don't forget stun:/turn: scheme in URL): {url:'stun:stun01.sipphone.com'}, {url:'stun:stun.ekiga.net'}, {url:'stun:stun.fwdnet.net'}, {url:'stun:stun.ideasip.com'}, {url:'stun:stun.iptel.org'

I need to establish a P2P UDP and TCP Connection between two Users. Both of them are behind a NAT. A little research leads me to STUN , TURN and ICE . Is there any Java solution (library) except jSTUN which seems to work only on UDP. And TURN, ICE is much better for the symmetric NAT Problem. Not to toot my own horn too much, but might I recommend trying IcedJava . (It's a part of the SipTools project) It's actively being developed, has a stable release 0.9 version, and supports use cases like RTP streaming out of the box. As far as TCP support, that's slated for a later release, but you're

I know about NAT traversal and about STUN, TURN and ICE and its use. I want to know whether these are implemented in peer to peer file sharing application like bittorrent. Whether trackers facilitate peers behind NATs to communicate with each other by helping in creating direct connection using STUN or relay through TURN. In the case of Distributed Hash Table(DHT) how one peer would communicate with other peer behind NAT ? BitTorrent does not need to connect to any particular member in a swarm, it's not a p2p chat protocol where two specific end points want to talk to each other. All it cares

I am working on a webrtc application and have to implement following TURN server. https://code.google.com/p/rfc5766-turn-server/ I am following this tutorial. http://www.dialogic.com/den/developer_forums/f/71/t/10238.aspx and it says to reference the TURN server as follows, in javascript code where RTCPeerConnection is created. var pc_config = {"iceServers": [{"url": "stun:stun.l.google.com:19302"}, {"url":"turn:<turn_server_ip_address>", "username":"my_username", "credential":"my_password"}]}; pc_new = new webkitRTCPeerConnection(pc_config); I am little confused, why are we referencing to
