Paper and pencil is your friend.  :-)

Basically, /lib/ndb only gets used for lookups.  Getting to
the point where you can ping your gateway doesn't use ndb
at all.

You can ping yourself, so your address is set up right.

What does "netstat -i" print?

Also, you might try "cat /net/arp" after you
try pinging your gateway.  If you see an OK
line for it, then we got the arp response;
if you see a WAIT, we're still waiting.

I'm starting to get suspicious of your
ethernet card itself though -- perhaps we've
not set up the interrupts right and aren't
receiving packets at all.

try "cat /net/ether0/0/stats".  Out minus in
should be non-zero.  Also, running "snoopy"
while you do stuff should show you packets
other than the ones from your computer.
If not, then we're almost certainly botching
the card setup.

What kind of ethernet card are you using?

Russ
