How to Allocate a Private IP address and Port with Ghostdriver

Question

I wrote a Ghostdriver Maven Java project where I call many instances of the jar file using a shell script in Ubuntu 14.04 64bit.

Each line in my shell script calls a new instance of my jar file.

The format of each line:

screen -dmS name java -jar /path/name.jar arg1 arg2 arg3

Currently I have 1 network interface (eth0) split up into multiple network aliases (eth0:1, eth0:2, etc), each alias points to a private IP which in turns points to a public IP.

I am trying to find the best way to allocate a private IP and possibly port number to each instance of my java program. Currently I call Ghostdriver inside my program.

The way I call ghost driver within my program:

public class className {

    PhantomJSDriver driver;
    public static final File PHANTOMJS_EXE = new     File("//home/username/phantomjs/bin/phantomjs");


    public className() {
        callGhostdriver();
        driver.quit();
    }

 private void callGhostdriver() {
        {
            DesiredCapabilities caps = new DesiredCapabilities();
            caps.setJavascriptEnabled(true);
            caps.setCapability("phantomjs.binary.path",
                    PHANTOMJS_EXE.getAbsolutePath());

            driver = new PhantomJSDriver(caps);
            driver.manage().window().maximize();
            actions = new Actions(driver);
        }
    }
}

Any help would be greatly appreciated.

***Update****

I tried changing the callGhostdriver method but had no success.

private void callGhostdriver() {
DesiredCapabilities dcaps = new DesiredCapabilities();
dcaps.setCapability(
        PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
        PHANTOMJS_EXE.getAbsolutePath());
String[] phantomJsArgs = {"--webdriver=172.16.190.131:6781"};
dcaps.setCapability(
        PhantomJSDriverService.PHANTOMJS_CLI_ARGS,
        phantomJsArgs);
driver = new PhantomJSDriver(dcaps);
driver.manage().window().maximize();
actions = new Actions(driver);
}

Argument --webdriver=IP:PORT seems to be overridden by a default --webdriver call.

Output from running jar:

*Apr 12, 2015 5:26:25 PM org.openqa.selenium.phantomjs.PhantomJSDriverService INFO: port: 8651 Apr 12, 2015 5:26:25 PM org.openqa.selenium.phantomjs.PhantomJSDriverService INFO: arguments: [--webdriver=172.16.190.131:6781, --webdriver=8651, --webdriver-logfile=/home/RemovedPath/phantomjsdriver.log] Apr 12, 2015 5:26:25 PM org.openqa.selenium.phantomjs.PhantomJSDriverService INFO: environment: {} [INFO - 2015-04-12T21:26:26.584Z] GhostDriver - Main - running on port 8651

Port 6781 with the different private IP should be what it is using but it uses 8651 instead.

I can set every capability but --webdriver=port, seems like you cannot change it, or it's a bug? — Hydtek, Apr 15 '15 at 00:50
Can I at least change the port that it uses? This way I can use iptables to manage traffic. Currently it just picks a port at random. — Hydtek, Apr 15 '15 at 22:51

I was able to find a hackish way to set the port but still haven't figured out how to set the private ip, I may have to use iptables to route the traffic.

private void loadLightWeightDriverCustom() {
    ArrayList<String> cliArgsCap = new ArrayList();
    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, PHANTOMJS_EXE.getAbsolutePath());
    cliArgsCap.add("--web-security=false");
    cliArgsCap.add("--ssl-protocol=any");
    cliArgsCap.add("--ignore-ssl-errors=true");
    capabilities.setCapability(
            PhantomJSDriverService.PHANTOMJS_CLI_ARGS, cliArgsCap);
    driver = new PhantomJSDriver(Configure(cliArgsCap), capabilities);
}

private PhantomJSDriverService Configure(ArrayList<String> cap) {
    return new PhantomJSDriverService.Builder().usingPhantomJSExecutable(PHANTOMJS_EXE)
            .usingPort(5555)
            .usingCommandLineArguments(
                    (cap.toArray(new String[cap.size()])))
            .build();
}

HALP, there gotta be a better way to do this. – Hydtek Apr 21 '15 at 19:27 — Hydtek, Apr 21 '15 at 19:27

Try this --> List<String> cliArgsCap = Arrays.asList( "--webdriver=172.16.190.131:6781"); dcaps.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, cliArgsCap);

Unfortunately this did not work, it gave me the same output that I previously posted "INFO: arguments: [--webdriver=172.16.190.131:6781, --webdriver=3205, --webdriver-logfile=/home/RemovedPath/phantomjsdriver.log] Apr 12, 2015 5:26:25 PM " [INFO - 2015-04-13T22:05:13.944Z] GhostDriver - Main - running on port 3205 so it seems like its overriding what I put in for webdriver with another webdriver argument. – Hydtek Apr 13 '15 at 22:37

I was able to find a fix to the --webdriver command, https://github.com/detro/ghostdriver/pull/438, I compiled that jar and loaded it in. Now I am getting

My method invoking phantomjs is:

  ArrayList<String> cliArgsCap = new ArrayList<String>();
    DesiredCapabilities capabilities = DesiredCapabilities.phantomjs();
    cliArgsCap.add("--webdriver=6666");
    capabilities.setCapability(
    PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,PHANTOMJS_EXE.getAbsolutePath());
    capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, cliArgsCap);
    driver = new PhantomJSDriver(capabilities);
