       kit, the following remedial kits should also be installed:



An ECO kit exists for DSNlink for Tru64 UNIX V2.3E on Tru64 UNIX 
4.0b through 5.0.  The DSNlink Release Notes contain a complete 
explanation of this release.  Below is a brief description of problems 
addressed in this kit:


o  X.25 Fixes

      - DSNlink can now communicate through X.25 router nodes. The
        local DTE address is now sent across as the first message.
        This should bypass any network problems where routers remove
        the address and/or subaddress.

o Modem Fixes

      - The dsnmmgr show line command did not include information about
        the HDLC layer.

      - The dsnmmgr zero line command has been added to reset the counter
        fields to zero in the HDLC statistics display for a modem line.

      - Messages from using the modem with DSNlink have been improved.

      - The dsnmmgr test wire command generated a device error message.

      - Several of the modem scripts went into a loop between the script's
        last two sections when the value 0 was not returned by the modem
        after receiving the modem-specific commands.

      - Modem script errors caused modem connections to fail because not
        all result codes were trapped and interpreted.

      - Links sometimes stuck on a modem line in the DONE or ABORT state.
        This happened when the line was in the ONLINE or LISTENING states.

o File Copy Fixes

      - When customers attempted to delete their copy of a file after
        copying it to Compaq, the -d option was not recognized.

      - The dsncopy command did not use the Support Center specified
        in the -S option.

      - File Copy server log files, /usr/lib/dsn/logs/dsn_file_server.log,
        contained debugging information in addition to the file copy records.

      - The Monitoring and Performance History (MPH) analysis tool did not
        submit files for processing on the host.

      - The Analysis Tool option did not work unless you supplied a service
        request number.

      - File Copy ignored the local authorizations file and allowed all
        DSNlink users to use File Copy.

o Interactive Text Search Fixes

      - The host software caused JACKETMSGCORRUPT errors.

      - When customers with access to many databases entered the show
        database command and then quit the listing, the quitting process
        took a long time because the server continued to send the entire
        database list.

      - When exiting ITS, there was a long pause before the system prompt

      - ITS ignored the settings for pagination, view, and highlight.

o Network Exerciser

      - The Network Exerciser measured the message transfer rate in
        bytes per second (Bps).

o Service Request Application Fixes

      - The Support Center option was ignored by dsnaug, dsncreate,
        dsnfetch, dsnreview

      - After successfully submitting a service request to the host, a
        prompt appeared asking you to Click Mail for a confirmation
        message. However, in the command line interface, there is nothing
        to click on.

      - If you attempted to fetch a list of closed service requests from
        a host that does not provide such lists, an error message window
        appeared and the process hung. The process had to be stopped from
        the command line.

      - In the local authorizations file, entries that allow access to
        the Service Request application, dsn_sra, incorrectly produced
        "You are not authorized to use this application" messages.

      - In the DECwindows Motif interface, when errors occurred connecting
        to the host followed by the user clicking on something in the window,
        the application stopped and generated random application termination

o Multiple Application Fix:

      - DSNlink could not start applications if there was a missing closing
        quotation mark in the final entry of any of the following files:

              o  dsn_config.dat, the configuration file
              o  dsn_remote_auth.dat, the remote authorizations file
              o  dsn_local_auth.dat, the local authorizations file

The following are enhancements to DSNlink Version 2.3E:

o A new command displays the DSNlink Version Number.

o The modem scripts supplied in DSNlink Version 2.3 for Compaq's DIGITAL
  UNIX have been updated to support additional Hayes and Hayes-compatible
  modems, Multi-Tech modem script changes, and scripts have been added

o New mail parameters for cross-platform consistency now allow customers
  who have DSNlink running on various operating systems to use the same
  parameters on each system to specify who gets communique mail from

o You can now adjust the pipeline depth in the Network Exerciser using the
  command dsnnetex -depth.

o Options have been added to the dsnmmgr test command. The dsnmmgr test
  command allows you to test your modem line.

o Customers can mail themselves a copy of the confirmation message that
  appears when they augment a service request.

o The ITS inactivity timer is suspended while customers are extracting
  an article to a file.

o The DSNlink Version Number has been added to log files.

o When a modem line is initialized, the modem script is now recorded in
  the logs or included in messages.


If you have a previous version of DSNlink on your system, you must
deinstall it before installing DSNlink Version 2.3E. If the previous
subsets remain in place, the installation fails.  For more details,
see the DSNlink Version 2.3E Installation Guide.

The deinstallation procedure removes the modem scripts in
/usr/lib/dsn/modem. If you modified DSNlink Version 2.3 scripts and
want to keep them, rename or move them before reinstalling DSNlink.
DSNlink Version 2.0 scripts are obsolete.

     1.  Become root and create a kit area on your disk by making a
         kit directory and extracting the kit archive.  For example:

           # mkdir kit
           # cd kit
           # tar xvf ../dsna235.tar

     2.  Uncompress and print or display the DSNlink Version 2.3E
         Installation Guide.  This command uncompresses the PostScript
         version of the guide:

           # uncompress dsna235_iguide.ps.Z

           The text version of the guide is dsna235_iguide.txt.Z.

     3.  Install the Version 2.3E kit using setld.  Refer to the
         instructions in the DSNlink Version 2.3E Installation

         During the installation, you will create an MD5 authentication
         key.  This is the key assigned by the Electronic Access Support
         Team for your access number.  Protect this key as you would a

     4.  Complete the appropriate postinstallation tasks as
         described in the DSNlink Version 2.3E Installation Guide.

The disk space requirements for loading DSNlink software subsets are as
follows.  To determine if your system has enough disk space, use the df

      Kit Size        Installation          /usr           /var

      7.3 MB             16.0 MB           14.0 MB        2.0 MB

The DSNlink installation procedure does the following:

     1. Presents an Electronic Service Tools agreement. If you agree
        to the terms, the installation procedure continues.

     2. Checks for the supported versions of Tru64 UNIX, Versions
        4.0b, 4.0d, or 5.0.

     3. Verifies that you have sufficient disk space for DSNlink.

     4. Checks for previously installed versions of DSNlink

     5. Prompts you for a unique group for the DSNlink executables
        and files

     6. Sets the group ownership of the files or directories to the
        group you created

     7. Prompts you for your access number or numbers, the node's
        name, your Customer Support Center, which transports you
        want to use with DSNlink, the name of a person to contact
        if Compaq must reach you by telephone, and your authentication

     8. Adds entries to /etc/services and /etc/inetd.conf for
        communications with the DSNlink host system, if you agree to
        the additions

     9. Prompts you for information necessary to configure each of the

     10. Runs the DSNlink Network Exerciser to test the connection to
         the host system

DSNlink modem processes must be stopped during the DSNlink Version 2.3E
installation.  DSNlink connections using DECnet, X2.5, or TCP/IP are not

DECnet/OSI for Tru64 UNIX may hang the installation.  We recommend shutting
down DECnet during the installation using the /usr/sbin/decnetshutdown
command.  You can restart DECnet using the /usr/sbin/decnetstartup command.

The change to support X.25 router nodes requires that all customers who use
X.25 and the host run DSNlink Version 2.2E. If you use X.25, contact your
