Several people have requested more detailed information about how to
run Envoy in a complex networking environment.  While supported, this
environment is not the intended target of Envoy.  When the concepts of
'routers', 'subnets', or 'netmask' enter into the picture, the
situation becomes terribly complicated.

Producing a tutorial on routing, subnetting, or any of the more
complex networking topics is far too formidable a task to enter into
here.  Entire books have been written that only scratch the surface of
explaining these subjects.  One we might suggest that covers IP, the
Network protocol in use in Envoy is 'Internetworking with TCP/IP', by
Douglas Comer.  Volume I.  ISBN 0-13-468505-9.

COMPLEX SETUP
=============

When installing Envoy, you're asked if you're in a simple or a complex
networking situation.  If this is confusing, the following points
might be helpful:

    - If you have an existing network that you (or someone) runs
      TCP/IP, Novell, or some other protocol on, you're in a complex
      situation.

    - If you want the ability to talk to another Envoy machine that
      isn't on the same physical network as yours, you're in a complex
      situation.

    - Universities, Businesses, and large organizations are all
      usually in some sort of complex situation.

    - If you've a handful of Amigas that you want to connect together,
      you are in a simple situation.


SIMPLE SITUATION
----------------

In a simple network, you should have to provide the following
information:

    (a) A name for each machine.
    (b) A unique number for each machine.
    (c) You're asked which networking device you intend to use.

The concept of Realms is -not- necessary for a simple networking
situation.


COMPLEX, 'internet' SITUATION
-----------------------------

If ANY of your Amigas are on different physical networks, you are
required to set up and maintain an Envoy Realm Server.  Please
reference the document 'Realms'.

At installation time, if you decide that your networking situation is
complex, (an 'internet' situation) the installer will ask you several
questions:

    (a) You are asked to provide a name for your Amiga.
        This is fairly self-explanatory.

    (b) You are asked to provide an IP address for your Amiga.
        If you are in an already-existing network, these are very
        likely allocated by a central authority.  An IP address is a
        32-bit number that uniquely identifies your machine.  If
        you're in a complex network situation, ask your network
        administrator for an IP address.

    (c) You are asked if your network is using the default subnet
        mask. A subnet mask is used to identify which portions of an
        IP address describe which mean "network number" rather than
        "machine number". Ask your network administrator for this
        information.

    (d) You are asked if you would like to select a network address
        for a default router. When several physical networks exist,
        the problem of figuring out what path should be taken to get
        from a machine on one physical network to a machine on a
        different physical network.  A router is either a computer or
        special piece of hardware acting as both a roadmap and traffic
        cop; directing packets to their destinations. Ask your network
        administrator for this information.

    (e) You are asked for the name of the Realm that your Amiga is in.
        A Realm is a logical grouping of machines into categories.
        For instance, 'Marketing', 'Design', 'Production', are all
        examples of what different realms might be.  For those
        confused, this is -not- DNS.  Read the document 'Realms' for
        more information.

    (f) You are asked for the name of your Realm Server.  A Realm
        server is an Amiga that agrees to act as a 'telephone book' --
        helping to convert the names of specific machines into IP
        addresses. Read the document 'Realms' for more information.

    (g) You're asked which networking device you'd like to use.
        Provided are Commodore's A2065 ethernet board, Commodore's
        A2060 ARCNET board, and an option to click 'Other'.
