What's the default route? TCP/IP requires (amongst other things)
an address and a default route. Here's one of mine:
% netstat -rn
Routing tables
Internet:
Destination Gateway Flags Refs Use
Netif Expire
default 66.76.96.1 UGS 0
17570 xl0
Probably your second action, after pinging localhost and your
local IP but before pinging Yahoo, should be a ping off the
"next-hop" gateway. Your ISP should have told you this, and
it should probably be in /etc/rc.conf as "defaultrouter"...
Or, try traceroute(1) with some address (66.218.71.112
will get you Yahoo!) and see what happens.
If you get a "no route to host" or similar, it's your IP
configuration; if it's "unknown host yahoo.com", it's
your name resolution, as Remko was pointing out.
If you have an IP addy but no gw, then you need to
run, as root:
#route add default ip.of.isp.gw
