[comp.protocols.appletalk] KIP, K-STAR incompatibility

CUSTEAD@sask.usask.ca (01/19/89)

We have a net full of fastpath 3's and fastpath 4's, with an Appletalk
Bridge (Shiva) connected as shown:


      ==================== Ethernet ===================================
            |                               |                     |
            |                               |                     |
       FastPath X                       Fastpath 3           Fastpath 4
            |
            | (localtalk)
            |
         SHIVA
        NetBridge
            |
            |  ZONEC


The Shiva Bridge publishes its own zone. (call it ZONEC)  This zone
is not known to the atalkad daemon that manages all of the fastpaths.

If Fastpath X is a fastpath 3, then all of the other 3's acquire ZONEC,
but none of the 4's know about it.
If Fastpath X is a fastpath 4, then all of the other 4's acquire ZONEC,
but none of the 3's know about it.

Each Fastpath seems to share ZONEC with only its own kind!
Fastpath X was made a core gateway for each test.

(The 3's run KIP and the 4's run K-STAR.)

Is there a explanation for this incompatibility??

One promblem may be the "ddprangestart"-parameter in the atalkatab-file.
If you use the "new & official" ddprange starting from 200, you will have
problems because the current K-STAR version uses the old ddprange starting
from 768. So, check your atalkatab-file and check if you have configured
the KIP boxes to use the new ddprange:
	L0 L0 L0 L0	S0 S200		# ipother atnetet ddprangestart
			    ^^^ this should be 0 or 768
If this is the case, change the "200" to "0" or "768".
This may solve the problem, but then again, it may not...

Hopefully Kinetics will come up with a new version of K-STAR, which will
  - use the new ddprange
  - provide filtering of AppleTalk objects (filtering of LaserWriters etc)
  - have "snmp" built in, as in the 0189 release of KIP from CMU
    (available from host lancaster.andrew.cmu.edu (128.2.13.21), in /pub)
