README.1ST for \latest\stack\


Description:
------------

This directory contains self-extracting zip files containg replacement
modules for the tcp/ip stack and stack utilities for "OS/2 Warp V4,
TCP/IP V4.0", component id 5639B1700, R510.

Also, customers who have installed Comm Server MPTS or MPTS WR08415 on
their Warp Connect or Warp Server system should update their tcp/ip
stack using the files in this directory.

IC18562.EXE has the most recent service to the tcp/ip stack.  It contains
a complete set of the latest tcp/ip stack .sys and .dll files.  All these
files are packaged together, whether or not they were changed by this apar,
because a compatible set of stack files is required for the correct operation
of tcp/ip on your workstation.


Prerequisites:
--------------

You must have either the fix for APAR IC16063 or MPTS FixPak WR08415 installed
before installing IC18562.EXE.

IC16063.EXE, which is also contained in this directory for your convenience,
contains an earlier version of the stack files, superceded by IC18562,
and additional serviced tcp/ip stack utilities which are not considered part of the
stack but are part of of tcp/ip on your system.

MPTS FixPak WR08415 is a "controlled release" FixPak. It also contains an
earlier version of the stack files, with more recent APAR fixes than IC16063,
but still superceded by IC18562, and the serviced stack utilities. The FixPak
also contains replacements for many other modules that are part of MPTS.
This FixPak may be obtained either electronically or on 3.5" diskette by
contacting Software Solutions Services at 1-800-992-4777.

All tcp/ip stack service is cumulative. The READ.ME file in IC18562.EXE
contains a complete list of tcp/ip stack apars that have been fixed in IC18562
since OS/2 Warp V4 GA.


Directions:
-----------

Have you already installed IC16063.EXE or MPTS FixPak WR08415 on your system?

   If you don't know, you can issue the following command:

      INETVER

   If the output is:

      Inet Version: 4.00e

   you haven't applied any service to the tcp/ip stack yet.

   If you decide to install MPTS FixPak WR08415, call Software Solutions
   Services and follow their directions to install the FixPak. Then install
   IC18562 as described below under "If you HAVE already installed IC16063
   or MPTS FixPak WR08415 on your Warp system........"

   If you decide to install IC16063, go to the section below beginning with
   "If you HAVE NOT yet installed IC16063.EXE ..."

                  ------------------------------------

If you get to this point, you HAVE installed tcp/ip stack service before since
the output of INETVER is not "4.00e". You can proceed to "If you HAVE already
installed IC16063 or MPTS FixPak WR08415 on your Warp system........" to
install IC18562.EXE.

If you want, you can determine if you have installed MPTS FixPak WR08415
by issuing the following command:

   SYSLEVEL

Does your output look like this?

   C:\MPTN\SYSLEVEL.MPT
   IBM OS/2 TCP/IP Stack
   Version 5.11.1     Component ID 5639B1700
   Current CSD level: WR08415
   Prior   CSD level: WR08400

If the "Current CSD level" is WR08415, then you HAVE installed the FixPak.

                  ------------------------------------

If you HAVE already installed IC16063 or MPTS FixPak WR08415 on your Warp
system, then you only need to install the files in IC18562.EXE to get the
latest service level of the tcp/ip stack. Do the following:

   You should create a temporary directory, copy IC18562.EXE into the
   directory, and unzip the stack files by entering:

      IC18562 .

   Note that the '.' is important because it will unzip all the files into the
   current path.  No subdirectories are created.

   Once this is done, see READ.ME (unzipped from IC18562) for complete
   installation directions.

                  ------------------------------------

If you HAVE NOT yet installed IC16063.EXE on your Warp V4 system, then
do the following:

   You should create a temporary directory, copy IC18562.EXE and IC16063.EXE
   into the directory, and unzip the files by entering the following, in
   sequence:

      IC16063 .
      IC18562 .

   Note that the order of issuing the IC16063 and IC18562 commands is
   important!  By issuing IC18562 after IC16063, the more recent stack files
   in IC18562 will replace the older files in IC16063.

   Note that the '.' is important because it will unzip all the files into the
   current path.  No subdirectories are created.

   Once this is done, see INSTALL.DOC for installation directions.  READ.ME
   (unzipped from IC18562) contains updated stack information for IC18562.
