    <p>I have a Selenium Grid running on AmazonEC2</p> <p>It consists of a hub running on port 7055 and a node running on port 7056.</p> <p>I have the following test:</p> <pre><code>var webdriver = require('selenium-webdriver'), driver = new webdriver.Builder(). usingServer('http://ec2-50-18-75-182.us-west-1.compute.amazonaws.com:7055/wd/hub'). withCapabilities({'browserName': 'firefox'}). build(); var postTitle = "Post "+(+new Date); driver.get('http://si-demo.herokuapp.com/posts/new'); driver.findElement(webdriver.By.id('post_name')).sendKeys("Selenium"); driver.findElement(webdriver.By.id('post_title')).sendKeys(postTitle); driver.findElement(webdriver.By.id('post_content')).sendKeys("This is auto generated by a test"); driver.findElement(webdriver.By.name('commit')).click(); driver.quit(); </code></pre> <p>That fails when I try to connect to the hub port. The test does run when I connect directly to the node port.</p> <p>The error I get when connecting to the grid hub is:</p> <pre><code>timers.js:103 if (!process.listeners('uncaughtException').length) throw e; ^ Error: ETIMEDOUT connect ETIMEDOUT at ClientRequest.sendRequest (/Users/jason/Development/cirrus/spanish-inquisition-runner/node_modules/selenium-webdriver/http/index.js:127:16) at ClientRequest.EventEmitter.emit (events.js:96:17) at Socket.socketErrorListener (http.js:1436:9) at Socket.EventEmitter.emit (events.js:96:17) at Socket._destroy.self.errorEmitted (net.js:329:14) at process.startup.processNextTick.process._tickCallback (node.js:244:9) ==== async task ==== WebDriver.createSession() at Function.webdriver.WebDriver.acquireSession_ (/Users/jason/Development/cirrus/spanish-inquisition-runner/node_modules/selenium-webdriver/lib/webdriver/webdriver.js:130:49) at Function.webdriver.WebDriver.createSession (/Users/jason/Development/cirrus/spanish-inquisition-runner/node_modules/selenium-webdriver/lib/webdriver/webdriver.js:109:30) at Builder.build (/Users/jason/Development/cirrus/spanish-inquisition-runner/node_modules/selenium-webdriver/builder.js:70:22) at Object.&lt;anonymous&gt; (/Users/jason/Development/cirrus/spanish-inquisition-runner/open_canvas.js:5:8) at Module._compile (module.js:449:26) at Object.Module._extensions..js (module.js:467:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Module.runMain (module.js:492:10) </code></pre> <p><strong>My question is:</strong> Does Selenium WebdriverJS support connecting to the hub? If so what am I doing wrong?</p> <p>Notes:</p> <ul> <li>I have connected to the hub and successfully run the same steps as an rspec test.</li> <li>I was also able to connect to the hub locally on the EC2 instance and run the test, only happens when trying to connect remotely to the grid.</li> <li>When looking at the Selenium2 grid console at :7055/grid/console it does appear to be using a session on the node.</li> </ul> <p>Commands I used on EC2 to start the grid:</p> <pre><code>Xvfb :0 -screen 0 1024x768x24 2&gt;&amp;1 &gt;/dev/null &amp; export DISPLAY=:0 java -jar selenium-server-standalone-2.32.0.jar -port 7055 -role hub xvfb-run java -jar selenium-server-standalone-2.32.0.jar -role node -hub http://localhost:7055/grid/register </code></pre>

    1. COPerhaps, when using WebDriver JS, you may need to run a particular version of the Grid Hub? From their site, it looks like 2.32.0 will work but maybe you should try 2.29 or another version and see if the error changes?

    2. COHow sure are you that you opened the ports from your selenium Hub to your EC2 instance? If it was me, I would run only the Grid Node on the EC2 instance and then I would run the hub on my own computer.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
