Selenium grid ubuntu host can't create node in Windows guest

Question

I want to create a Selenium grid hosted in my ubuntu linux 12.04. My goal is to make this selenium grid communication with a Windows VM with a node role. My problem is that when i create the selenium grid in the Windows VM i have this error

14:35:00.200 INFO - Registering the node to the hub: http://xxxxx:4444/grid/register 16:35:01.232 INFO - Couldn't register this node: Error sending the registration request: Connect to xxxxx:4444 [IP] failed: Connection refused: connect

My VM is a Windows XP. I try to disable the Firewall. I'm sure that is a Ubuntu problem, because with an other Windows VM, the problem is the same. I can ping Host to Guest and Guest to Host In ubuntu, i disable the firewall too, but nothing change.

In ubuntu i declare the hub like this

java -jar selenium-server-standalone-2.52.0.jar -role hub

In the Windows VM i declare the node like this

java -jar selenium-server-standalone-2.52.0.jar -role node

Any ideas about what is blocking the communication ? Thanks for help _

Answer 1

make sure during the virtualization process, the ports 4444 for the grid and 5555 for the nodes are being opened.

Then in your node role, make sure to specify the -hub parameter. when not specifying the hub parameter, it defaults to localhost .
