Well, you could get your DHCP server to make your linux box the
default router. Then set you're linux box's default route to be the
router by hand, and tell it to forward packets:
echo 1 >/proc/sys/net/ipv4/ip_forward
Then next time the Mac (or whatever) connects to your LAN you should
be able to watch the traffic. Of course, you'll also be burdened
with forwarding all the LAN traffic across your linux box, but for
purposes of debugging.
I could use another F-18 box ...
And of course, Macs are BSD UNIX. Run trafshow there! You might
have to install MacPorts (or Fink or HomeBrew etc) to get trafshow
installed, but any Mac _wants_ that anyway!
I try to avoid messing with her Mac. I'm not familiar enough with it and
I can't get close enough to the screen due to the physical arrangement,
vision problems, 'ah the golden years!'
And of course you could hand set the default route on the Mac for
debugging purposes just as with any UNIX box, and avoid mucking
with the router DHCP advertisements until you want to frib with
iPhones etc.
