Hi folks,

I need help! I'm convinced that CAP will do exactly what I need, but my
knowledge of Apple networking leaves much to be desired, and I think
that that's why I'm not getting anywhere.

I'm running a small pool of Sparcstations (SunOS 4.1.1b) and a single
Mac IIci (System 6.0.5). I have a LaserWriter IIntx that up to now has
been attached to the Mac. After I heard of CAP, I decided to give it a
try, mainly to be able to use the LW from the Suns. I want things to
look like this when I'm done:

               Twisted-pair ethernet (TCP/IP, Appletalk)
 <=========================================================>
         |             |         |         |        |
         |             |         |         |      ... 3 more Suns
    ------------    -------   -------   -------
    | Mac IIci |    | SLC |   | IPC |   | SS2 |
    ------------    -------   -------   -------
                       |
                 ------------
                 | LW IIntx |
                 ------------

The networking software I have on the Mac is the AppleShare stuff that
came with the system and Ethernet Phase 2 that came with the Ethertalk
card we bought.

I have CAP 6.0, patch level 100, and after reading through the
documentation several times I decided that what I want is Native
Ethertalk Phase 2 (using the NIT interface). Is this correct, or should
I be using UAB?

CAP compiled correctly, and I ran "aarpd le0 CoLing". I assume that I
can define the zone name this way because I can't find any way to do
that directly on the Mac. This produced an etalk.local that looks like
this:

	#
	# EtherTalk dynamic configuration data
	#
	# Last update:	Tue Apr  7 16:48:32 1992
	#
	# Generated by Native EtherTalk (Phase 2)
	#
	interface   	"le0"
	netRangeStart	 0.00
	netRangeEnd 	255.254
	thisNet     	255.00
	thisNode    	41
	thisZone    	"UniFr-Coling"
	bridgeNet   	 0.00
	bridgeNode  	0
	bridgeIP    	127.0.0.1
	nisNet      	255.00
	nisNode     	41
	asyncNet    	 0.00
	asyncZone   	""

I then called atis, but that didn't change anything in etalk.local. In
my opinion, the file doesn't look quite right because our IP domain is
132.230.17. I would think that at least bridgeIP should start off with
this number. In any event, something seems to be wrong because a
getzones produces the following error:

	error -1096 getting zone list

Am I correct in thinking that the numbers consisting of two numbers
separated by a period, e.g. 255.254, are AppleTalk network numbers?
Should thisNode be somehow related to the IP address of my Sun
(132.230.17.5)? Should bridgeIP be the address of one of my Suns?

If anybody is interested in the output from an "aarpd -ddanpsk -D20 le0
unifr-CoLing", I can send it to him. I can't figure it out but the
numerous timeouts don't seem to be a good sign.

If I do need to use UAB, what about the problem with Phase 1 vs. Phase
2? UAB only knows Phase 1 and my Mac has Phase 2. The CAP documentation
says that Phase 2 can be set up to be restricted to Phase 1, but I
can't figure out how to do that. Can I get hold of Phase 1 somewhere,
from Apple maybe?

Does anybody know what I'm doing wrong? Do I need additional software
on the Mac (Internet Router, maybe?) or do I need - heaven forbid -
hardware? Or should I just give up hope?

Hopefully,
Matthew Wyneken
