I believe the problem is that you do not have a network interface, perhaps your ethernet card is not known to plan9? Alternatively it may need some options in plan9.ini (set the plan9.ini manpage).
You can check that plan9 knows about your ethernet card by typing cat /net/ether0/addr (to see its MAC address), and basic ip activity can be proved by looking at arp activity (cat /net/arp). If these are both ok then try ip/ping www.google.com. -Steve
