I went through the newest Docs to install the Alpha 4 stack, and was just trying to populate it with some data.
ES 5.0-4 works
Kibana 5.0-4 works
Filebeat 5.0-4 works
But when I tried to install Packetbeat, everything seems normal, until I do the validation step (where you hit a web page and then check ES for new data in packetbeat-* indices).
I have XPACK installed and Shield enabled with the default username/password.
I am using all default configs - no changes (except for a couple of extra paths in the filebeat config for log files)
So.. ES is on 9200, Kibana is on 5601... it's all bound to localhost.
I took a trace for Packetbeats, but none of it made much sense to me, and i'm not completely sure what to check for. I did doublecheck the packetbeat config, and port 80 and 8080 were both enabled.
I am running this on a Virtual Machine through VMWare Workstation running on a Windows 10 PC.
