This screenshot was captured with Emacs running on Mac OS X, but connected to a BBB
with the hostname slartibartfast . Everything on this screen is running on the BBB.
In the top-left corner, the frame shows a live debugging session with the GNU debugger
( GDB ) on a simple C program. In the bottom-left corner, the frame shows the compilation
result obtained from running gcc on the BBB. In the top-right corner, the frame shows
the interactive gdb session. Lastly, in the bottom-right corner, the frames show the current

and then you'll have to make the same change in /etc/hosts . If you struggle to choose
a proper name, you will find some comfort in the following XKCD comic:
