APPLETLK.NLM v3.06 RELEASE NOTES
(c) Copyright 1992, Novell, Inc. All rights reserved.


This file describes the updated APPLETLK.NLM software (v3.06), including
new fixes and enhancements. This NLM is compatible with the AppleTalk
Support Package v3.0 or later and NetWare for Macintosh v3.0 or later.

GENERAL NOTE

Periodically, Novell provides patches and software updates to correct
problems in its software products. Before you apply a Novell patch or
update, take a moment to read the accompanying release notes and verify
that the software you plan to update is the correct version.


IMPORTANT NOTE: THE APPLETLK.NLM v3.06 SHOULD NOT BE USED WITH THE NETWARE
MULTIPROTOCOL ROUTER

The APPLETLK.NLM v3.06, or any previous versions of this NLM that are
included in NetWare for Macintosh or the Appletalk Support Package,
*cannot* be used to replace the APPLETLK NLM in the MultiProtocol Router.
This is because the APPLETLK.NLM v3.1 in the MultiProtocol Router has WAN
capabilities that are not supported by the APPLETLK NLM v3.06.

For questions regarding the NetWare MultiProtocol Router, please refer to
that product's documentation.


INSTALLATION INSTRUCTIONS

Follow these instructions to install APPLETLK.NLM for NetWare for Macintosh
or the AppleTalk Support Package:

1. Rename the old APPLETLK.NLM in the SYS:SYSTEM directory so that it will
not be overwritten when you install the new NLM. For example, you can call
it "APPLETLK.OLD."

2. Copy the new APPLETLK.NLM to the server's SYS:SYSTEM directory.

3. Down the server by issuing the DOWN command at the server console and
then reboot the server. (Or reload APPLETLK.NLM using the command-line
options described in your documentation.)



NEW FEATURES AND FIXES IN APPLETLK.NLM v3.06

This section describes updates and fixes to both the AppleTalk router and
to the AppleTalk protocol stack.

UPDATES TO THE APPLETALK ROUTER:

Problem 1: In the previous release of APPLETLK.NLM, the sender's network
number in the first two bytes of the RTMP data portion was byte-swapped in
all but the first packet of responses that required more than one packet.

Symptom: On a Phase 1 network, it was possible for a node that learns its
network number by broadcasting RTMP requests to be dynamically configured
with the wrong network number.

Resolution: The sender's network number is now set correctly when multiple
RTMP data packets are sent in response to an RTMP route data request.


Problem 2: In earlier releases of APPLETLK.NLM, the last zone name of one
reply packet and the first zone name of a subsequent reply packet for a
multi-packet reply could be duplicated if routes without zones appeared in
the routing table.

Symptom: Duplicate zones names sometimes appeared in the Chooser.

Resolution: This problem is fixed.


Problem 3: BIND or LOAD commands could fail.

Symptoms: BIND and LOAD commands could fail when zone names included
leading, trailing, and embedded spaces, or when certain keywords were used
in the BIND or LOAD line command

Resolution: BIND and LOAD commands that use zone names with leading,
trailing, and embedded spaces are now allowed. LOAD and BIND commands with
LOAD or BIND command line keywords are allowed. However, zone names that
include leading and trailing spaces are *not* supported on the LOAD command
line.


Problem 4: The router sometimes responded to Echo protocol requests by
setting the source net number field in the response packet to the
requesting node's net number instead of its own net number.

Symptom: The destination router sometimes responded with the requesting
node's network number.

Resolution: The AppleTalk router now responds correctly to Echo requests.


UPDATES TO THE APPLETALK PROTOCOL STACK:

Problem 1: Some users reported difficulties maintaining idle ADSP
connections.

Symptom: In the previous release of the APPLETLK.NLM, applications such as
NetWare for SAA, NetWare SQL, and some third-party applications could lose
their ADSP connections if the application did not receive transmitted data
after a couple of minutes. For example, a backup application lost its ADSP
connection to the Macintosh during the time it took to change a tape
cartridge on the backup device.

Resolution: This problem is resolved.


Problem 2: AFP sessions hanging under certain limited conditions.

Symptom: In the previous release of APPLETLK.NLM, an ASP ATP request was
checked to determine that it came from the correct remote endpoint. If this
check failed for any reason, AppleTalk disregarded subsequent requests,
causing the AFP session to hang.

Resolution: Now AFP will not hang under the above conditions.
