Can't connect to the internet with the StarHPC Standalone Image

If you're having issues connecting to the internet from within the StarHPC Virtual Machine image on a machine connected to the internet, please read the steps below carefully.

1. Start up the StarHPC standalone virtual machine image and login. (see docs)
2. Open a terminal by right-clicking the desktop and selecting “Xterm” out of the drop down menu
3. Run:
   /sbin/ifconfig -a
4. Look for an entry named ethX where X is an integer (usually 0, 1, or 2) and jot down the number X. In the image below, X is 1.
   
5. Open a terminal and edit the file /etc/network/interfaces by running
   
   sudo nano -w /etc/network/interfaces
   Enter starhpc08 for the password if prompted
6. Replace all instances of “eth0” in this file with “ethX” where X is the number from step 4 above. (in the image below, X was 1)
   
7. Press Ctrl-O, and then press Enter to save the file (NOTE: Ctrl-O means hold down the Control key and press the letter “O” at the same time). Next press Ctrl-X within nano to exit nano.
8. Now run in a terminal:
   
   sudo /etc/init.d/networking restart
   (Type in starhpc08 for the password if prompted.)
9. The network should now be working. You can test by right-clicking the desktop and selecting firefox. Navigate to StarHPC's homepage to test for internet connectivity.
