[comp.protocols.appletalk] Using KIP or KSTAR

paul@aucs.UUCP (Paul Steele) (09/10/88)

I have a small Appletalk net set up which has 2 KPFS 4's bridged to
our Ethernet backbone.  I am attempting to install atalkad on our Sun-4
and would like to know if the KStar package that comes with the gateway
is adequate or should I use the KIP stuff that comes with CAP.  I was
told that KIP only runs on KFPS 2 and 3, but there is no mention of
KStar in the KIP/CAP documentation.  Any info would be appreciate.

Well, as I understand it, the current implementation of KIP will not
run on a Fastpath-4.  But I expect that Bill Croft will have a new
version out sometime soon.  KStar, however, will use atalkad if you
want it to, so you can make entries for your KFPS-4's in your existing
atalkatab (or, in your case, you can just start running KIP and have
the kboxes boot from your Sun).

Be careful, though -- we have been unable to get two KFPS-4's in the
same zone to work.  When the second box is booted, both boxes refuse
to give out IP addresss (we are running KIP).  We're expecting new
PROMs from Kinetics today (and a new version of KStar too) so I hope
that solves our problem.  If you have problems with two boxes and not
one (and you've sure you've configured correctly) you might give
Kinetics a call.

You can make entries in the current atalkatab and atalkad will boot up
upon KFPS-4 startup, no problem here.

As I said in an earlier letter to the net, I have been unable to get ONE
KFPS-4 to work for longer than a minute or two before it pukes its guts out.

  ^^^^^^^^^^^^^^^

Be patient...I called last week no less than 7 times(tuesday-wednesday-thursday
leaving a message each time) before I got through to somebody on friday (and 
somebody even returned one of my previous calls an hour later!).  I have sent 
them diagnostic and set-up data but still am starting from square one (still 
waiting for them to get back to me, heavy sigh...only four calls and messages 
this week).  I did notice and alerted them to the fact that if you "print 
configuration" in the FastPath Manager.  On the LaserWriter output, the listed 
address for the "IP address of Administrater host" will be the same as the "IP 
Subnetwork Mask" (try it), I REALLY hope that it's just a print routine problem.

There is one bad "real" bug in K-STAR and one bad "theoretical" bug
in K-STAR (K-STAR being the download module supplied with Kinetics'
FastPath 4).

The bad "real" bug is the one Dave Finkelstein mentions above:  it is impossible
to have more than one K-STAR (or one K-STAR and one KIP) box "in the same
zone" (which is to say: connected to LocalTalk networks which are in
the same zone).

The workaround for this bug is, clearly, to keep the LocalTalk zones unique.
We recognize that this workaround is not possible in all environments, and
*I* (having produced the bug) sincerely apologize for the inconvenience
(and confusion) this bug has caused.

The bad "theoretical" bug is that K-STAR may, in certain environments, reply
to the wrong DDP address when responding to "=:IPADDRESS@*" or
"=:IPGATEWAY@*" NBP Lookups.  What happens is that K-STAR responds to the
source address in the incoming DDP packet; what it should do is respond to
the address in the NBP-tuple in the incoming DDP packet.  The reason this is
a "theoretical" bug is that, in most cases, the two addresses are the same
(for an obscure reason having to do with how AppleTalk bridges have 
traditionally dealt with NBP Broadcast Requests).  However, it has come up
with one customer testing K-STAR with their own, in-house developed,
AppleTalk bridge (which deals with NBP Broadcast Requests in a slightly
different, and likely more conformant, manner than many current AppleTalk
bridges).

Anyone adversely affected by either of the two bugs mentioned above
should contact Kinetics technical support at (415) 947-0998 to get
in the queue for a fix.

Again, apologies for the bugs.
