Issues with Netatalk and MACE

[David Riley <fraveydank%gmail.com@localhost>]

Hello all,

I've been trying for the last day or so to get Netatalk (specifically with 
Appletalk networking, for some older Macs) working properly and I'm a bit 
stumped.

When I launch atalkd (/etc/rc.d/atalkd start), I get the usual business about 
not being able to register the workstations because NBP registration is timing 
out.

Digging a little deeper, I see on the network that I'm sending out multicast 
AARP requests for my own address (let's call it 42.182 for now).  "tcpdump 
-nvvvXe aarp" shows that I'm asking who-has 42.182 from 42.182.  Sadly, though, 
my own machine doesn't see those requests (MACE doesn't get its outgoing 
broadcasts/multicasts looped back, it seems).  If I instrument 
sys/arch/macppc/dev/am79c950.c to print out every MAC address that comes across 
in the Rx interrupt, I never see that frame.

So I modified sys/netatalk/aarp.c such that aarpresolve recognizes when my own 
address is being requested and responds with my own MAC address.  Now I can see 
(with tcpdump) the NBP requests getting sent over the interface from my own MAC 
address to my own MAC address, but again, they never really seem to get picked 
up.

I feel like I'm probably going about this the totally wrong way.  Does anyone 
else have Netatalk with atalkd running successfully on a MACE machine?  I'm 
running 5.0.2 basically stock (with a slightly modified GENERIC kernel).
