4. UNINSTALLING PREVIOUS VERSIONS OF TCP/IP

It is not required to uninstall previous versions of TCP/IP but if
you choose to, the following steps are recommended.

NOTE: Be sure to get all the required ZIP (tcpip43.zip) files
      for installing TCPIP 4.3 prior to start this UNINSTALLATION
      process.

  Go to TCP/IP Shadows ICON and click on Uninstall TCP/IP 4.21
  Icon. Go through the uninstallation screen(s) select all the
  components in the component selection page and proceed to
  complete the uninstallation of all the components (TCPIP APPS,
  DHCP/DDNS, NFS, VPN).

NOTE: On OS/2 Warp 4.0 machine you might not find the TCP/IP
      Shadow icon. In such case install TCP/IP 4.3 over
      the present TCPIP.

  1. Go to CONFIG.SYS and remove all the statements which
     refer to TCPIP directory.

  2. Reboot the system.

  3. You may have to manually remove some files in the
     TCPIP subdirectory.

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

5. INSTALLING TCP/IP 4.3

NOTE: Before you install TCP/IP V4.3, make sure all of the prerequisite
      software are installed on your system.

To install TCP/IP V4.3:

  1. Make a subdirectory for:

     o  TCP/IP V4.3(includes MPTS 6.0)

     To make a subdirectory, from an OS/2 window:

     a. Make a root-level temporary directory; type:
        'md temp'

     b. Go to temp; type: 'cd temp'

     c. Make a temp\tcpip43 subdirectory for
        TCP/IP V4.3; type: 'md tcpip43'

  2. Download and install TCP/IP V4.3 (with MPTS 6.00):

     Note: This procedure will install the new MPTS
           and TCP/IP programs in the directories that
           contain your existing MPTS and TCP/IP.

     a. With your Web browser, navigate to the
        IBM TCP/IP V4.3 for OS/2 download page.

     b. Click on the Download push button and
        download the TCP/IP V4.3 for OS/2 package
        to the temp directory you created in step 1.

     c. Make temp\tcpip43 your current directory.

     d. Using an unzip program that can create
        subdirectories, unzip the tcp43.zip
        file.  (For example, enter
        'unzip tcp43.zip' or an equivalent
        command like 'pkunzip2 -d tcp41.zip'.)

     e. Type 'cd tcpip' (that is, make
        temp\tcpip43\tcpip your current directory)

     f. If you are upgrading over a previous
        version of TCP/IP and you do not wish
        to install the function in Secure
        Remote IP Client, you can type
        'install /a-' from a command prompt
        and skip to step z.  If you want to install
        Secure Remote IP Client, type 'install'
        and continue with step g.

        For more information on CID installation,
        see the TCP/IP Guide.

     g. When asked whether to install a more recent
        version of MPTS, Click Yes.

     h. Click OK on the Multi-Protocol Transport
        Services logo window, if necessary.

     i. Click Install on the Multi-Protocol
        Transport Services window.

     j. Click OK on the MPTS Target Drive window.
        Do not change the Target Drive letter.
        It should point to the drive where MPTS
        is currently installed.

     k. If a Reinstall MPTS window appears,
        click OK.

     l. When the Installation Complete window
        appears, click OK.

        Note: If the system is configured for "IBM
              OS/2 NetBIOS over TCP/IP" then the
              following configuration change must
              be made, otherwise proceed to step m to
              keep the current MPTS configuration.

         l-1. Click Configure on the Multi-Protocol
              Transport Services window.

         l-2. In the Configure window, the LAN Adapters
              and protocols radio button should be
              selected and click on Configure.

         l-3. In the LAN Adapter and Protocol Support
              window, under "Current Configuration",
              double click on the first instance of
              "IBM OS/2 NetBIOS over TCP/IP".

         l-4. In the NetBIOS over TCP/IP window, the
              driver parameters radio button should be
              highlighted and click on Configure.

         l-5. Look for "TCP-Frame descriptors" parameter
              and decrease the current value by 20. For
              example, if it's currently configured for
              132, change it to 112.

         l-6. Click OK to save.

         l-7. Click Close at the NetBIOS over TCP/IP window.

         l-8. Click OK to complete the configuration change
              in the Adapter and Protocol Configuration window.

         l-9. Click Close at the Configure window to save the
              configuration change.

        Note: Failure to make this configuration change to
              "IBM OS/2 NetBIOS over TCP/IP" protocol, may
              result in the following error during re-ipl:

              sys1201: The device driver
              C:\IBMCOM\PROTOCOL\TCPBEUI.OS2 specified in the
              DEVICE statement on line xx of the CONFIG.SYS was
              not installed.  Line xx is ignored.  This error
              will cause other errors to follow during ipl.

     m. When the Multi-Protocol Transport Services
        window appears, click Exit.

     n. When the Update CONFIG.SYS window appears,
        verify that "Update CONFIG.SYS" is selected.
        If there is more than one boot drive on your
        system, verify that the only the current boot
        drive is highlighted. Click Exit.

     o. When the CONFIG.SYS Updated window appears,
        click OK.  This completes the MPTS install.

     p. Wait for the TCP/IP installation program to
        continue.

        Note: Netscape is used by the TCP/IP install
        program.  If Netscape has never been started
        on this system, the Netscape "New Profile
        Setup" panels will display.  If this happens,
        click on "Next" on all panels, then click on
        "Finish" to complete the Netscape profile setup.

     q. When the TCP/IP V4.3 for OS/2 Installation
        window displays, click the Forward (right arrow)
        button at the bottom of the window.

     r. On the Welcome to TCP/IP V4.3 for OS/2
        Installation window, click Guided Path.

     s. In the next TCP/IP V4.3 for OS/2 window, select
        any new components you wish to install.
        TCP/IP components that have been previously installed
        will be preselected.  Leave them selected.

     t. The NFS checkbox will be preselected whether or not
        NFS is installed. If NFS is already installed on the
        system and you try to unselect NFS an information
        window is displayed that says NFS 2.0 is no longer
        supported and will be upgraded to NFS 3.0.

     u. Click Forward.

     v. Type your Administrator Password in the
        Drive Selection for TCP/IP 4.3 for OS/2
        window, if you plan to do any remote TCP/IP
        configuration or administration.  (A utility
        shipped with TCP/IP V4.3, ADMIN_PW, may be
        used from the OS/2 command line to set or
        reset this password at a later time.)

        Your current TCP/IP path will also be displayed
        on this page.  Do NOT change this path.

     w. Click Forward.

     x. Click the Install (diagonal arrow) button at the
        bottom of the Ready to Install TCP/IP 4.3 for
        OS/2 window.

     y. Click the Exit (X) button at the bottom of
        the Installation Complete for TCP/IP V4.3
        for OS/2 window.

     z. Shut down and restart your computer.

Messages for errors that occur during installation
are recorded in these files:

    TCP/IP install log:
      <boot_drive_letter>:\os2\install\tcpinst.log

    Feature-Install install logs:
      <boot_drive_letter>:\os2\install\current.log
      <boot_drive_letter>:\os2\install\fisetup.log
      <boot_drive_letter>:\os2\install\wpinstal.log

    MPTS install log:
      <boot_drive_letter>:\os2\install\lapshist.log

    Locked-file log:
      <boot_drive_letter>:\os2\install\ibmlshst.log

After installing TCP/IP V4.3 and verifying that the
installation(s) completed successfully, you can delete
the entire \temp directory tree.

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

6. UNINSTALLING TCP/IP 4.3 INSTRUCTIONS

  Once you have installed TCP/IP V4.3, it can be
  uninstalled by using the Uninstall TCP/IP V4.3
  icon in the TCP/IP Shadows folder.  After running
  the uninstall program and rebooting the system, you
  may need to clean up any files still remaining in
  the TCPIP subdirectory.

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

7. Dynamic IP Changes

o DHCP Server and BINL Server :

  The DHCP Server has modifications supporting the
  Wired for Management Specification 2.0. This caters
  to the clients using Preboot eXecution Environment (PXE)
  2.1 specifications of INTEL. This specification also
  requires another server called the Boot Image Negotiation
  Layer (BINL) Server. The BINL Server works in conjunction
  with the DHCP Server and provides certain parameters to
  the Network Computer enabling them to Bootup.

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

8. Known Problems, Restrictions, and Considerations

  Known problems, restrictions, and considerations
  with TCP/IP V4.3 include:

Java Considerations:

o The TCP/IP V4.3 Java programs may run slowly,
  particularly on low-end computers.

o Occasional traps have been observed in various
  Java components.  If a trap occurs, reboot your
  machine.  Usually the traps cannot be recreated.

o One of the traps observed was when Lotus Domino 4.6.3
  Server was also installed. The trap occurred on
  running tcpcfg2 from the icon. (This is the TCIP/IP
  Configuration icon found in TCP/IP Configuration
  folder in the TCP/IP Shadows folder). The following
  error was encountered:

  SYS2070
  Segment Load Error: JAVA->JAVAR._strtodiee

  The error can be corrected as follows.
  In the LIBPATH in CONFIG.SYS move all strings related to
  JAVA (Eg: X:\JAVA11\DLL, X:\JAVA11\ICATJAVA )
  before the occurrence of "X:\NOTES"

  An example is given below.

  Change the following LIBPATH
  LIBPATH=x:\netscape\program;x:\notes;x:\java11\dll;x:\java11\icatjava\dll;x:\java11\icatjava\daemon;

  to the one given below
  LIBPATH=x:\netscape\program;x:\java11\dll;x:\java11\icatjava\dll;x:\java11\icatjava\daemon;x:\notes

  Note: Here X: is a generic reference to indicate a drive.
  It might not be the same on your machine.

o Scrolling with the mouse may result in a hung
  application.  If this happens, press the Ctrl
  and Esc keys simultaneously to get a window
  that may let you end the application.

  You can avoid the problem by scrolling with the
  Page Up and Page Down keys or with the up arrow
  and down arrow keys.  Using the slider bar always
  results in a hung application whenever the mouse
  pointer moves off the slider bar.  Using the up
  and down arrows on the scroll bar sometimes results
  in a hung application.  This problem is fixed in
  Java 1.1.3 and subsequent releases.

o 16-color display may appear less than optimal.
  Select 256-colors or higher (if possible).

  Note: Higher screen resolution may use more storage.

o To save on storage you may want to set the Java heap
  size to 2 MB (the default is 8 MB).
  To do this, change the command files in \tcpip\bin
  that run the JAVA programs :
  ex: admin_pw.cmd,
      dadmgui.cmd,
      binlscpc.cmd,
      binlscps.cmd,
      ddnsapc.cmd,
      ddnsaps.cmd,
      dhcpscpc.cmd,
      dhcpscps.cmd,
      tcpcfg2.cmd,
      tcpcfg2d.cmd and
      tcpcfg2r.cmd.

     Add the -ms option after the Java keyword.  For example:

     Java -ms2 <additional parameters as appropriate>

o If you use HPFS386, setting the HPFS cache size
  smaller (for example, 2048) than the default in
  <boot_drive_letter>:\IBM386FS\HPFS386.INI can improve
  performance of the configuration notebook when a large
  amount of data is involved.

o When running the TCP/IP Java configuration programs
  (for DDNS, DHCP and TCP/IP) remotely, if you are
  running on Windows 95, you may encounter an "Out of
  Environment Space" error while trying to start the
  program. If this happens, edit the properties for
  your MS-DOS prompt.  On the Memory tab, increase
  the value for Initial environment.

o If you try to run the Java configuration programs
  through the applet viewer on a machine that is
  low on memory, you may get this exception:

     JAVAI.DLL 0002:0001ECAD
     P1=00000001  P2=011A2800
     EAX=011A2800  EBX=001B0004 ECX=0  EDX=FFFFCA00
     ESI=8  EDI=0168CA68

  Try freeing up more memory before restarting the program.

Installation status:

o If you are reinstalling TCP/IP V4.3, make sure
  that the configuration notebook is not running
  during the reinstall.

o When using the TCP/IP V4.3 Install graphical user
  interface (GUI), wait for each page to completely
  display before doing any mouse or keyboard actions.
  Manipulating the GUI too soon may hang your computer;
  if so, you will have to restart it.

o When installing TCP/IP V4.3 from a LAN directory,
  if a message asks you to insert a CDROM, your LAN
  may have gone down.  Cancel that message and reinstall
  after your LAN comes back up.

o If you are using Netscape Navigator 4.61, you may notice
  some anomalies or errors in the Display of Installation
  GUI. You will have to refresh your screen to clear
  these errors. Refresh can be done by pressing the
  Ctrl-R key together. The following anomalies and errors
  were seen during installation of TCP/IP 4.3.

  The following anomalies/errors were noted during
  Installation.

  -  In the "Selected Components" screen the DHCP/DDNS
     SERVER checkbox might come up checked even though
     you do not have the DHCP/DDNS Server installed.
     In this case, if you do not wish to install the
     DHCP/DDNS Server feature, uncheck the box and
     continue.
  -  In the "Select and Configure Components" screen
     the Drive combo box and the Configure button are
     not clear. Refresh the screen and the correct
     icons will appear.

  The following anomalies/errors were noted during
  Uninstallation.

  -  In the "Select Components" screen the DHCP/DDNS
     Server checkbox comes up abled and unchecked.
     This should not be present. Refresh the screen
     and you will see the correct screen.

Configuration status:

o If you experience a hang while scrolling, see the
  scrolling with a mouse description in the Java
  considerations section, above.

o PMX and NFS users who want to Autostart their programs must
  do so using the TCP/IP V4.3 Configuration Notebook
  and not the PMX Configuration Notebook.
  There is no Autostart tab in the new PMX notebook(tcpcfg.exe).

o PMX and NFS will not appear in the selection list
  on the Autostart tab unless these programs are
  installed on your computer.

o It is possible to edit the trusers file manually
  and migrate that file to tcpnbk.lst rather than
  make changes using the configuration notebook.

o To mount the file systems exported by NFS2.0 Servers, using NFS3.0 Client,
  -soff option needs to be specified in the mount command.

        Example:   mount  -soff  k:  9.184.209.22:c:\temp

  In the above example, mount command is run on NFS3.0 client and "c:\temp"
  is a file system exported by NFS2.0 Server.

o FSATB.INI is used in conjunction with NFSSTART.EXE. Each entry in FSTAB.INI
  is a valid "MOUNT" command entry. NFSSTART picks up each line of this file
  and mounts the drives as specified.
  Example:
                mount k: 9.184.209.22:c:\temp
                mount -soff p: 9.184.209.44:c:\docs
                 .
                 .
                 .
                etc.,

  ***************** Attention **********************
   If you change tcpnbk.lst using the Configuration
   notebook, and subsequently edit and migrate the
   trusers file, the files will not be synchronised.
   Making changes through the configuration notebook
   is the recommended solution.
  **************** End of Attention*****************

  Before the initial install, edit the trusers file
  in the etc directory (find it by typing set etc at
  a command prompt).  Changes made before the initial
  install will be properly reflected in tcpnbk.lst.

  After the initial install, to add a new user:
      1. Edit trusers and add the new user
      2. Run "install /a- /c"      (config-no-install)

  After the initial install, to change or delete a user:
      1. Edit trusers and change or delete the user
      2. Delete tcpnbk.lst
      3. run "install /a- /c"      (config-no-install)

o When using the instructions in the TCP/IP Guide
  for Installing the TCP/IP Java Configuration Applications
  on a Remote Workstation, step 4b is not necessary.
  You can supply the IP address on the command line when
  you start the program. For example, DDNSAPC 1.2.3.4
  would start the DDNS Server configuration program
  connecting to the machine with the IP address 1.2.3.4.

o Multicast Configuration - By default, TCP/IP V4.3 uses
  the functional addressing mode for multicast
  transmissions.  Some industry standard routers by
  default listen for multicast frames in broadcast mode.

  To configure an interface for broadcast mode multicast,
  add the MULTIBC parameter to the ifconfig statement in
  \mptn\bin\setup.cmd for that interface.  For example:

      ifconfig lan0 multibc

  For Cisco 4700 series routers and IOS version 11.2(7),
  changing the router multicast mode to use functional
  addressing may cause the router to have boot problems.


PMX status:

  PMX is not supported in TCP/IP V4.3, but those users
  who already had PMX on their machines before TCP/IP V4.3
  was installed shall continue to use PMX with the
  new PMX CONFIGURATION NOTEBOOK (tcpcfg.exe).

  Those who install PMX separately after having installed
  TCP/IP V4.3 need to manually bring in the file TCPCFG.EXE
  from the TCPIP\SAMPLES\BIN directory into the TCPIP\BIN
  directory and use it.

NFS status:

 If you have NFS 2.0 installed on your system, installation of
 this package automatically upgrades NFS 2.0 to NFS 3.0
