Accessing your environment : SQLNet/OCI

If your environment was set up with Host networking as described in these pages then the host and guest VMs all have IP addresses in the 192.168.88.* subnet.
Your host machine (Windows or OSX) is accessible at 192.168.88.1.
Your VMs are assigned 192.168.88.10, 192.168.88.11, etc.

Run and X Windows Server on your Host

For Windows I usually install MobaXTerm.
After install:

• Run MoxaXterm
  
• Settings -> Configuration
  
• Click the X11 tab
  
• Change the "X11 Remote Access" dropdown to "full"
  
• Answer Yes to restart X11 to enable configuration change
  

This will allow MobaXTerm to act as an XWindow server for any machines that can contact it.

Install a test program
I usually install one of the standard x utilities like xclock so I can show that XWindows is working.

vagrant ssh
sudo yum install xclock

Run the test program

export DISPLAY=192.168.88.1:0

xclock The xclock analog clock program will run on the VM but it will use the graphical console on your host PC to show GUI. Ctrl-C the process on the Guest VM or close the xclock window on the Host machine.
