Turns out the problem was the chair->keyboard interface, sort of.

I was *filtering* the tcpdump output, looking for 10.66.0.3.  Naturally, 
this won't work, because 10.66.0.3 is the *gateway*.  It is neither a 
source nor destination, and therefore won't show up.

Someone mentioned using snoop -V port 80, which showed the traffic leaving 
the interface.

In further diagnosing, I used snoop -v to get lots of detail, and saw 
the destination mac was the mac of the gateway, so it *was* going to the 
right place.

It turns out that this is a problem further down the network, and probably 
due to several hacks and kludges that we've been forced to put into place 
because the infrastructure is not entirely finished.

So, while I still can't connect where I need to, we now know there's no 
problem with Sun machine itself.

Thanks very much for the help!
