javascript - Node.JS TCP STUN server not receiving connection from RTCPeerConnection -


i've been doing localized testing on webkitrtcpeerconnection in chrome 43, , running local tcp server in node.js receive stun packets peers. client code (for local testing) follows:

// chrome    var iceservers = {      iceservers: [{        url: "stun:localhost:8080"      }]    },    optional = {      optional: [{        dtlssrtpkeyagreement: true      }, {        rtpdatachannels: true      }]    },    peer1 = new webkitrtcpeerconnection(iceservers, optional),    peer2 = new webkitrtcpeerconnection(iceservers, optional);    peer1.createoffer(function(offer) {    peer1.setlocaldescription(offer);    peer2.setremotedescription(offer);    peer2.createanswer(function(answer) {      peer1.setremotedescription(answer);    });  });

my node.js tcp socket server meant receive stun packet , log now. tcp stun server outlined in rfc 5389. here's code it:

var net = require('net'),     options = {         allowhalfopen: true     },     port = 8080,     server = net.createserver(options, connectionlistener);  server.listen(port, listening);  function connectionlistener(connection) {     var data = '';      console.log('connection opened');      connection.setencoding('utf8');      connection.on('data', function (buffer) {         console.log('data received');          data += buffer;     });      connection.on('end', function () {         console.log('data stream ended');          connection.end();          console.log('----\n%s\n----', data);     }); }  function listening() {     console.log('listening on port %d', port); }

when client code finishes running, peer1.iceconnectionstate "checking", , peer1.icegatheringstate, peer2.iceconnectionstate , peer2.icegatheringstate remain "new". nothing logs on tcp server except listening on port 8080. can tell me why no connection opened if peer1.iceconnectionstate "checking"?

powershell Start-Process exit code -1073741502 when used with Credential from a windows service environment -

i'm running strange behavior powershell start-process call. here call: $process = start-process ` "c:\somepath\mybinary.exe" ` -passthru ` -credential $defaultcredential ` -wait ` -workingdirectory "c:\somepath" ` -loaduserprofile if ($process.exitcode -ne 0) { #do } this call return exit code - 1073741502 . after quick search, exit code seems related generic error when program not load required dll (aka. status_dll_init_failed ). when run without -credential $credential program runs correctly. in order isolate problem, manually launched some.exe in prompt target credential , runs smoothly. so problem seems come way start-process cmdlet launch process. i found potential solutions problem tried apply no luck : link , link . would have idea of what's going on here ? edit 1: run proc mon monitoring program activities when launched directly or via powershell script. problem seems occur when loading kernelbase
