How to Allocate a Private IP address and Port with Ghostdriver - ip

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

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

Answer 1

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();
}

Answer 2

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

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);
