How do you connect remotely using Python + Webdriver

Question

Hello,

I am trying to figure out how to connect to my remote webdriver instance.

This is the code I am currently using:

from selenium.remote.webdriver import WebDriver

driver = WebDriver("http://172.16.205.129:4444", "firefox", "ANY")
driver.get('http://google.com')
driver.quit()

I find that I can't connect and will get a connection refused, or if i play around with the code, occasionally a time out.

Any help is appreciated.
