7.8 How can I tell if I need more than a 2-user license?

    There are several fundamental things to remember about HP-UX licensing:

        o Series 700 and Series 800 users are now counted the same way
        o Display console counts as one user
        o Each ASCII terminal counts as a user, regardless of how it is
          connected
        o The LAN connection counts as one user

    ASCII Terminals

    The simple rule to remember is any ASCII terminal that is logged in
    counts as a user.

    ASCII terminal connections can come in several different forms:

        o Direct-connected via a serial terminal multiplexer
        o Connected via Data Terminal Concentrators (DTCs) or via
          terminal servers
        o Personal Computers (PCs) acting in terminal emulation mode,
          whether connected via serial line or via Local Area Network (LAN)

    X-terminals and workstations

    When a customer buys an X-terminal or workstation from HP or from
    another vendor, HP acknowledges that the customer has also bought a
    single Unix license-to-use.

    Therefore, the customer has the right to an unlimited number of logins and
    terminal windows _over_the_LAN_ to a Series 700 or Series 800 from either
    X-terminals or workstations. These logins can be via X terminal windows
    (_hpterm_ and _xterm_), _telnet_, _rlogin_, or other means.

    PC's that use X-terminal emulation software such as XView each count the
    same as an X terminal. This is because the PC essentially becomes an
    X-terminal when it is running the X server software. Therefore, when a PC
    is running an X-terminal emulator, the PC has the right to an unlimited
    number of logins to an HP-UX system.

    Exceptions

    The policy of counting DTC users is new for the Series 700. Customers who
    purchased Series 700 systems prior to HP-UX 9.0 shipments (late calendar
    1992) and use them as host systems for multiple DTC- connected terminals,
    may continue to use those configurations without buying a license upgrade.
    An update to HP-UX 9.0 will not lock out these configurations.
