06/88 REVISION OF KIP (KFPS IP)

The June 1988 revision of KIP is primarily a maintenance release
providing improved capabilities for UDP port assigments and better
functionality with non-KIP bridges.  In addition, KIP now prints out a
version number when starting up.

UDP PORT ASSIGNMENTS

Previous revisions of KIP used a range of UDP ports started at 768 to
map the "well known" DDP sockets from 0 to 127.  This was done to
allow a fixed mapping from the DDP socket well known space to the well
known UDP port space.

In April, 1988, the NIC assigned a number of ports:
  201 - AT-RMTP  -  AppleTalk Routing Maintenance
  202 - AT-NBP   -  AppleTalk Name Binding
  203 - AT-3     -  AppleTalk Unused
  204 - AT-ECHO  -  AppleTalk Echo
  205 - AT-5     -  AppleTalk Unused
  206 - AT-ZIS   -  AppleTalk Zone Information
  207 - AT-7     -  AppleTalk Unused
  208 - AT-8     -  AppleTalk Unused
for this purpose.

Note that there are 126 (0 is invalid) ddp well known sockets to map
to space of 8 udp ports.  DDP Ports 1 through 63 are reservered for
use by Apple and new assignments for these will be applied for as they
are put into use by Apple.  DDP ports 64 through 127 are designated
for experimental use only.

KIP now allows the specification of a different start range of UDP
ports to accomodate these new assignments.  It does not check to see
if the ports have been assigned.  You should be warned that it can
conceivably use the UDP ports rangestart+1 through rangestart+127.
However, in practice, only the "named" ports (e.g. at-nbp, etc) will
be used unless you use the experimental ports which probably isn't
recommended in any event.

To do this, an unused field on the Kinetics box configuration is used
(right after the ethertalk specification).  A value of 0 implies the
mappings starting at 768.  A value of 200 specifies the NIC assigned
values.  WARNING: use of any other start values is NOT recommended.

atalkad will warn of conflicting port usages between different
Kinetics boxes in the same atalkatab.

CAP 5.0 is configured to use the new port mappings by added specified
names to /etc/services.  In particular, it looks for the following
"official service names":
	at-nbp, at-rtmp, at-echo, at-zip
by using getservbyname.  (man getservent for more information).


NON-KIP BRIDGE FUNCTIONALITY

Revisions of KIP prior to 6/88 had a tough time with non-KIP bridges.
This was especially true of KIP 9/87.  The problem was in the fact
that KIP did not do Zone acquistions on routes.  As of KIP 6/88 zone
acquisitions are done.

VERSION

KIP now prints out a version number along with the number of buffers,
etc. when it starts up.  This is viewable from Prompt's (2.0 or later)
"Show Diagnostics".


OTHER CHANGES

EtherTalk length was getting reset in the wrong way.

Allzones was on for "unknown" zones.
