Selen Grid Node kann keine Verbindung zum Hub herstellen

Question

Ich versuche, einen Selenium Grid Hub auf meinem Mac zu initiieren und dann einen Knoten auf einer Windows 7 VM auch auf meinem Mac (in VirtualBox ausgeführt, wenn das wichtig ist) einzurichten. Ich verwende diesen Befehl auf dem Mac:

java -jar selenium-server-standalone-3.0.1.jar -role hub 

Und dann bekomme ich

Nodes should register to http://10.10.3.1:4444/grid/register/ 
Selenium Grid hub is up and running 

fantastisch, groß. Ich gehe dann in meine Windows VM und führe den folgenden Befehl aus:

java -jar selenium-server-standalone-3.0.1.jar -role webdriver -hub http://10.10.3.1:4444/grid/register -port 7777 -debug 

Es wird schließlich Timeout, keine Verbindung herstellen. Ich habe die Debug-Informationen unten eingefügt.

* edit: Ich habe versucht, den Hub und Knoten sowohl an den Fenstern VM, und es funktionierte ohne Probleme laufen. Ich habe auch versucht, den Hub und den Knoten nur auf dem Mac auszuführen, und ich habe das gleiche Problem. Das sagt mir, dass das Problem irgendwie mit meinem Mac zusammenhängt. Keine Ahnung, was zu tun ist ....

Answer 1

Es stellt sich heraus, der Server, bei dem Versuch, dem Hub automatisch eine IP-Adresse zuzuweisen, wählte die falsche. Aus irgendeinem Grund wählte er die IP-Adresse des VPN-Gateways. Hinzufügen von -host 10.11.xx.xx behoben mein Problem.
