[comp.protocols.appletalk] uab question

mday@pollack.mmwb.ucsf.edu (Mark Day) (03/17/90)

I have retrieved the uab package from Columbia, and I have a question
on exactly what it is doing. (I can't seem to find simplistic enough
explanation in the included documentation).

My interpretation is that uab allows your UNIX host to communicate
with an Ethernet connected Mac directly using Ethertalk as the 
protocol, no UDP encapsulation, no muss, no fuss.
Is my interpretation correct?  
If so this doesn't solve our problem of how to provide network services
to an Ethernet equipped Mac that is hiding behind a Proteon gateway.
(which won't pass EtherTalk packets)

The relevant section of our configuration map:

                       __________
		       |         |
		       |         |
  _____________________| Proteon |______________________________
	    |          |	 |            |               |
        ---------      |________ |        ---------       ---------
	|       |                         |       |       |       |
	|  Mac  |                         | K-Box |       | AUFS  |
	|       |                         |       |       | server|
	---------                         ---------       ---------



Since there is only one Mac on the far side, we don't want to spring
for yet another K-box, if we can get away with a cheaper solution.
Is there any way to get the AppleTalk through that is more cost effective
that buying a K-box?

Thanks,

Yes, that's right. It uses the facilities available on a few
UNIX boxes to get at raw Ethernet frames.

You could buy an EThernet interface for your Mac - that's
cheaper than a KBox in the short term, but works out expensive
if you buy some more Macs. Can't you trade-in your Proteon box
if it isn't actually doing what you want it to do?
