1. Introduction
===============

In the past, the Passport software has been distributed as part of each
individual client product which uses it, such as uniBasic, IQ, etc.  Starting
with version 3.3, the Passport software is distributed as a separate product.

Release of the Passport as a separate product serves several purposes:

o   Makes it easier to determine which version of the Passport software is
    being installed.

o   Makes it easier for the same Passport software to be used with upcoming
    DCI products.

o   Helps eliminate the possible redundant installations which can occur when
    two or more DCI products are installed on one system.  This can be
    especially troublesome if one installs a second or third DCI product and
    that product happens to contain an older release of the Passport software,
    because the older release will overwrite a newer release.

Therefore, it is DCI's intention to begin the process of removing the Passport
as an integral part of each product, and to distribute it as an independent
product.  Although it can be ordered separately, a copy of the Passport software
will still continue to be shipped together with all DCI products which require
it.


2. Installation
===============

To install the Passport software: from root, copy the distributions contents
into a suitable working directory (e.g. /tmp) and run "ppinstall".  For
example:

    # cd /tmp
    # cpio -ivcdu </dev/rct0
    # ./ppinstall

The ppinstall script will move the distribution files to their appropriate
places, and then invoke "ppconfig" to configure the Passport for your system.


3. New Features
===============

    Changes for Release 3.6.2
    ===========================

    o   Fixed software licensing failures on the Linux x86 (6D) platform,
        particularly Red Hat systems.

    Changes for Release 3.6.1
    ===========================

    o   Fixed a memory leak which caused the Passport process to grow ever
        larger as dL4 or IQ users began new sessions.

    o   Fixed software licensing failures on the Linux x86 (6D) platform 
        when used with root file systems larger than 2 gigabytes.

    o   Fixed an infinite loop in software licensing on the Linux x86 (6D) 
        platform.

    Changes for Release 3.6
    =========================

    o   New utility - makeosn.  "/usr/bin/makeosn" is a utility used to
        produce OSNs (OEM Security Numbers) for use with protected
        programs in both uniBasic and dL4.

    Changes for Release 3.5.1
    =========================

    o   Added support for SCO Open Server in platform 99


    Changes for Release 3.5
    =======================

    o   Fixed problem where an incorrect version number was supplied when
        other programs, such as uniBasic (LEVEL command), queried the passport
        daemon.

    Changes for Release 3.4
    =======================

    o   "/etc/passport".  Release 3.4 of the Passport daemon program.  3.4 adds
        support for the new platform numbers 0x07 (PowerPC 603 AIX) and 0x29
        (Power AIX).

    Changes for Release 3.3
    =======================

    o   "/etc/passport".  Release 3.3 of the Passport daemon program.  3.3 adds
        the -V option to determine version number and establishes a fixed log
        file name of "/etc/DCI/passport.log" (command-line redirection is no
        longer supported; see note on security below).

    o   "/usr/bin/ppconfig".  This is identical to uniBasic's "ubconfig", i.e.
        it configures the default startup command line for the Passport daemon.

    o   New utility - ssnmaint.  "/usr/bin/ssnmaint" is a new program which was
        designed to be the preferred method for entering or changing the license
        status on all DCI products, current or future.  In other words, ssnmaint
        can handle all maintenance of a system's SSN.

    o   New utility - ppstresstest.  "/usr/bin/ppstresstest" is a diagnostic
        program which can help identify faulty hardware Passports.

    o   New installation program - ppinstall.


4. Miscellaneous Notes
======================

o   Security:  There is a possible security risk present for existing
    installations of the Passport software, in that it is possible that
    users other than root may write to "/etc/DCI/passport.cmd", the Passport
    daemon startup command file.  To make an existing installation secure,
    perform the following from root:

        # chown root /etc/DCI /etc/DCI/passport.cmd
        # chmod 755 /etc/DCI
        # chmod 755 /etc/DCI/passport.cmd

    For new installs, "ppinstall" ensures that both of these files have the
    appropriate permissions.  As a further optional step, the system
    administrator may wish to control modification of the system SSN by:

        # chown root /etc/DCI/ssn
        # chmod 644 /etc/DCI/ssn

    This would ensure that only the superuser can delete or modify the SSN.
