The menu bar at the top of the Ethereal window should have a "Capture" 
menu.  Select "Start" from that menu.

If you are doing this on some UNIX-compatible system (Linux, BSD, 
Solaris, HP-UX, etc.), you might either have to run Ethereal as root, or 
configure the system to allow non-root users to capture network traffic. 
 See

	http://wiki.ethereal.com/CaptureSetup_2fCapturePrivileges

for details on this.

Selecting the "Start" menu will open a new window; there will be a 
"Capture" section, with a field labeled "Interface:".  That should have 
the name of a network adapter in it, and there should be a "drop-down 
list" that you can select with the usual "combo box" widget (it'll 
probably have a triangle pointing down) which should give you a list of 
network adapters.  Select from that list the adapter on which you want 
to capture.  (If no interfaces are listed, see
