Hi,

I've several questions concerning KIP/CAP and the Dayna EtherPrint box. First
I'll summarize our network topology and explain the problem.

The important part of our network looks like:

	  -------
	  |     | SUN SPAR
	  ------- station [131.211.145.26]
	     |
<--------------------------------------------------------------> thin ethernet
     |                   |                            |
   -----               -----                     -----------
   |   | UNIX hosts    |   | EtherPrint          |         | Apple IIfx
   -----               ----- box                 ----------- [131.211.145.34]
			 |
		     ---------
		     |       | Apple LaserWriter II/ntx
		     ---------

I've installed the LaserWriter (LW) as a local printer for the Apple IIfx, and
as a remote printer for the UNIX hosts. All this works fine. The UNIX hosts
are:
* 1 HP 9000 series 835 running HP-UX 7.0	[131.211.145.16]
* 1 HP 9000 series 400T running HP-UX 7.0	[131.211.80.2]
* 1 HP 9000 series 340 running HP-UX 7.0	[131.211.145.28]
* 1 SUN SPARC station running SunOs 4.1.1	[131.211.145.26]

The ethernet carries TCP packets and EtherTalk (== AppleTalk over ethernet)
packets, the latter sent by the IIfx. The EtherPrint box translates the
EtherTalk packets into LocalTalk packets. This is necessary because that's the
only prototcol the LW understands.

My goal is that I want to access the LW directly from all machines connected
to the network, that is *without* burdening the IIfx. From dyer@spdcc.COM
(Steve Dyer) I understood that CAP can be used for this because he wrote:

   "The EtherPrint box works fine with RU-CAP using the "papif" utility plus
   TransScript. I'm running CAP on a SUN SLC and share a TI Microlaser PS with
   a Mac IIfx"

I ftp'd CAP, and from the docs I understood that I also need KIP so I ftp'd
that too. I installed KIP on the SUN SPARC station and tried to understand how
to configure it. From what I understand, KIP provides routing information
towards Kinetics Boxes (and EtherPrint boxes???) by mapping aplletalk net
numbers to IP-addresses.

My questions are:
1. Did I correctly understand the functionality of KIP?
2. The EtherPrint box has no internet address, nor can it be assigned one,
   because it doesn't understand the TCP/IP protocol. Is this a problem?
3. What do I have to put in the /etc/atalkatab and /etc/atalk.local files?
4. Is it enough to only edit the atalk.local file? In other words: do I really
   need the atalkatab file?
5. If 2. *is* a problem, what alternatives do I have?

Any help will be appreciated! Please send e-mail to:

or just post in this newsgroup.
