javascript - Node.js Selenium IPv6 Issue (SocketException Protocol family unavailable) - Stack Overflow

This error only happens when I spawn the ios-driver jar as a Node.js child.

The error is java.SocketException: Protocol family unavailable

selenium-test.js:

var spawn = require('child_process').spawn;

var selenium = spawn('java', ['-jar', './ios-server-standalone-0.6.6-SNAPSHOT.jar', '-port', '4444']);
selenium.stderr.setEncoding('utf8');
selenium.stderr.on('data', function (data){
  console.log(data);
});

webdriverjs-test.js (webdriverjs)

var webdriverjs = require('webdriverjs');
var options = {
    desiredCapabilities: {
        browserName: 'safari',
        platform: 'OS X 10.9',
        version: '7.1',
        device: 'iphone'
    }
};

webdriverjs
  .remote(options)
  .init()
  .end();

Reproduce this error by creating the above files, running selenium-test.js in one window and webdriverjs-test.js in another window. You will first need to npm install webdriverjs and curl -O .6.6-SNAPSHOT.jar

Version info:

$ java version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

$ node -v
v0.10.26

Why does this error happen and how do I fix it?

• Host about var selenium = spawn('java', ['-jar', './ios-server-standalone-0.6.6-SNAPSHOT.jar', '-port', '4444', '-host', '127.0.0.1']);? – Joachim Isaksson Commented Apr 3, 2014 at 4:23
• Just tried. Same issue happens. – Maros Commented Apr 3, 2014 at 4:25
• Do you have JAVA_OPTS that has -Djava.preferIPv4Stack=true in your environment. That could be a reason. Also try passing them to your child process. See this question – user568109 Commented Apr 3, 2014 at 4:54
• I don't think so. I can inspect the output of env in my shell and in the child shell and they are almost the same. – Maros Commented Apr 4, 2014 at 0:25

I managed to solve this by making the spawned child ignore stdin:

var selenium = spawn('java', ['-jar', './ios-server-standalone-0.6.6-SNAPSHOT.jar', '-port', '4444'], {stdio: ['ignore', null, null]});

I'm not sure why this workaround works.

I don't have much idea about it, what so far I've found is that this can be binding issue with java. More details is on following link:(It is not the updated information, it may lead to answer)

If that is not the case, as this post suggests to change it to higher port should work. "Protocol family unavailable" error while using VisualVM
