            GETTING UUCP UP AND RUNNING FOR REAL


    This UUCP distribution in general is not for the uninitiated.  That is,
    it is not user friendly.  This particular document outlines a general
    installation procedure.  Be warned that there are a LOT of things you
    will have to do to bring up UUCP on your machine.

    This document shows a TYPICAL setup.  You will most likely want to
    modify the example to fit your own needs.  I cover all the points
    though.

    (1) You made backups of the distribution floppies, right?  DO NOT
    MODIFY THE DISTRIBUTION FLOPPIES.  The instructions below are
    long and some are complex and you may wish to refer to the
    original distribution diskettes if you accidently mess something
    up.


    (2A) Installing UUCP on a single floppy system.

    Well, it *is* possible, but difficult.    you need to make as much
    space as possible available on the main floppy.

    The second distribution disk contains only the source and manual
    pages.    I suggest you shuffle things around a bit.  You already
    have a copy of the first distribution diskette. I suggest you
    format a new disk and put the MAN directory of the second
    distribution disk on it.  Note that there is a MAN directory
    on the boot disk as well but this one contains only dmail.help
    which you need to gain online help from dmail.

    The following executables are required on the boot floppy and
    should not be moved off.  You should move as many of the remaining
    executables somewhere else as you can.

        Required Executables in C

        c/dmail
        c/getty
        c/rmail
        c/uucico
        c/rnews
        c/uucp
        c/unbatcher
        c/dme        (unless you configure your own editor)
        c/sendmail
        c/uux
        c/uuxqt

    You will want to change the ASSIGNments in s/startup-sequence
    as follows:

        Assign UUSPOOL:    UUCP:SPOOL
        Assign UUMAIL:    UUCP:MAIL
        Assign UUNEWS:    UUCP:NEWS

    These directories MUST be in nonvoltile storage or your USENET
    node will be unreliable.

    (2B) Installing UUCP on a duel floppy system.

    In this case very little shuffling is required.  I suggest
    the second floppy be used for UUSPOOL:, UULIB:, UUMAIL:, UUNEWS:,
    GETTY:, and UUPUB:.

    Format a new floppy (this will be your second floppy) and create
    directories as follows:

        MakeDir df1:spool
        MakeDir df1:mail
        MakeDir df1:mail
        MakeDir df1:news
        MakeDir df1:pub
        MakeDir df1:lib

    Modify the Assignments in s/startup-sequence of the boot floppy
    as follows:

        Assign UUSPOOL:    df1:spool
        Assign UULIB:    df1:lib
        Assign UUMAIL:    df1:mail
        Assign UUNEWS:    df1:news
        Assign GETTY:    UULIB:
        Assign UUPUB:    df1:pub

    Copy df0:lib to df1:lib and either delete or rename df0:lib to
    prevent confusion.  What we have done is move all dynamic storage
    to df1: .. files that will change a lot or require a lot of disk
    space.    Specifically, UULIB: was moved to DF1: because the
    sequence number file is kept in UULIB: and this is updated for
    each mail message sent.

    (2B) Installing UUCP on a Hard Drive

    Make a directory called UUCP on your hard drive somewhere.  And
    Assign UUCP: to it.   Copy the contents of both distribution
    floppies to your harddrive:

        (put first disk in DF0:)
        1> Copy df0: UUCP: ALL CLONE
        (put second disk in DF0:)
        1> Copy df0: UUCP: ALL CLONE

    It is easiest to keep all the directories in one place.  Note
    that a MAN directory exists on both distribution floppies, simply
    merge them together.

    Merge the startup-sequence on the boot floppy into your master
    startup-sequence.  Make sure you get all the Assigns and that
    they are properly reassigned to the appropriate directory on
    the harddisk.  Most people normally make a master UUCP: assign
    as a reference point to other assigns.


    Be sure that UUSPOOL:, UUMAIL:, UUNEWS: and UUPUB: are assigned
    to your hard disk instead of ram.

    You will most likely want to run DCron and Getty from your
    startup-sequence.  Be sure that UUCP:C is assigned *before*
    these programs are run so they pick up the appropriate path.

    If Getty interferes with any terminal program you might use
    you may be forced to BREAK it.    Remember to restart it to
    enable incomming UUCP calls again.

    DCron is an extremely useful utility to run, especially in
    systems with hard disks.  The only thing you have to watch out
    for is to be sure to BREAK it (kill it) before shutting off your
    machine.  DCron writes to its log file and runs other programs
    based on the date and you don't want to accidently turn off your
    machine when DCron has just started up some other program that
    may write to your hard disk.

    In the context of UUCP, DCron is normally used to automatically
    poll systems in the wee hours while you are asleep, to trim
    log files automagically, and maybe disable the modem's speaker
    while you are asleep (at least, that is what I use it for).

    Most people with HDs running UUCP leave their Amiga's on 24 hours
    a day.

                Other System Directories

    Merge the mountlist into your master mountlist and copy any
    devices from l that you do not already have into your
    master l directory.

    merge or copy uucp:s/crontab to s:crontab and uucp:s/.edrc to
    s:.edrc .

    You can ignore files in uucp:system, they are standard system
    files.

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

    (3)     Other startup-sequence efficiency considerations

    UUCP relies heavily on the Amiga's multitasking capabilities.
    Most programs execute other programs.  Many programs in UUCP:C
    may be made resident as shown by the pure bit being set.  You
    will probably at least want to make C:RUN resident if you haven't
    already.

    Depending on available RAM you may want to make certain other
    progams resident.  Here are some suggestions:

        uucp:c/dme        ; run by dmail to edit mail
        uucp:c/uuxqt        ; run by uucico to handle received files
        uucp:c/rmail        ; run by uuxqt to handle received mail
        uucp:c/sendmail     ; run by dmail to handle outgoing mail

        (note that uucp:c/sendmail and uucp:c/rmail are the same
         executable just renamed)

    STACK:    All programs should run with a stack of 8192.  This
    has been tested for all programs except RNews and ANews which
    may require more.

    RNEWS:    RNews currently takes a huge amount of memory and
    will run only on machines with at least 1.5MB of ram.  Even
    with 1.5MB you may need to run rnews manually instead of having
    it automatically run by uuxqt.    In this case rename the rnews
    executable to something else and create a dummy script file
    in its place (named as 'rnews') with the script bit set.

    (4)     System requirements

    Be sure you are running at least version 1.3 of the operating
    system.  The main consideration is that you are using at least
    the 1.3 serial device.

    The NULL: device is required, this is in the l directory of
    the boot floppy as already discussed.

    The UUSER: device is not required unless you want to start
    getting fancy with the Getty.  This is mainly a programmer's
    tool.

    (5)     Getty

    Normally one runs a Getty in his startup-sequence on the internal
    serial port (from which you wish to receive calls).  Currently
    only one Getty may be run PER SERIAL DEVICE NAME, and using other
    units of a given serial device will interfere with Getty's operation.
    This is due to the difficulty of implementation in Getty and will
    eventually be fixed (to fix the problem I have to patch into
    the OpenDevice and CloseDevice vectors).

    So for now you can really only run Getty on the internal serial
    device.

    Getty does its best to not interfere with comm programs and
    the like, but if a comm program refuses to run because it
    can't get exclusive access to the serial port you may have
    to kill the Getty by BREAKing it from a CLI.

    Refer to the manual page MAN:Getty for more information (for
    floppy based systems all manual pages are on the second
    distribution diskette).

    (6)     SHELL-STARTUP

    Assuming you are using the 1.3 Shell, the S:Shell-Startup file
    normally contains at least a Path command and Stack command to
    properly setup a newshell's path and stack.  Be sure the stack is
    at least 8192 for this distribution of UUCP and add the UUCP:C (or
    wherever you have placed the distribution executables) to your path
    list.  Older UUCP distributions required a huge stack, this has
    been fixed.

    (7)                   SITE-SETUP CONTROL FILES

    The following is a description of control and log files required
    for UUCP and how you must modify them to install your system.

    (GETTY: is normally Assign'd to UULIB:)

    GETTY:Getty-Header

        This file contains the header line that is printed before a
        login: prompt and is typically only two or three lines long.
        The header usually contains your node name and the version of
        the OS you are running under so people calling from term
        programs know who you are.

        (Getty can be used to run things other than uucico)

        Modify accordingly.

    GETTY:Passwd

        The password file is used by Getty to authenticate login
        requests.  In the context of UUCP, remote UUCICOs that call
        your machine up will provide a login and password.    Getty
        handles this and if the login is valid and the password matches
        will run the appropriate program found in the password file.

        Getty also deals with such features as automatic disconnect on
        timeout and logs times for all incomming and outgoing calls.

        In a serious system you should first remove all the junk
        entries that come with the distribution.   You need an entry
        for each remote machine you want to be able to call you.  You
        do not necessarily need to give them logins that corrospond to
        their machine names though this is how it is usually done.

        Other programs in the future will be able to be run from
        a Getty.

        Later versions of UUCP will implement MAILER-DAEMON type
        stuff like 'unknown user', in which case the password file
        will be used to define which user names are valid on the
        system.

    GETTY:LOGFILE

        The logfile is appended to by Getty whenever an incomming
        call occurs or somebody takes over the serial port.  It
        logs connect and disconnect times for incomming calls and
        usage for external programs.

    UULIB:Domain

        In nearly every case you will not need this file.

        Those of you who wish to do domain routing through
        their machine or have more than one default for
        unknown destinations should refer to the manual
        page MAN:Domains.

    UULIB:.Signature

        .Signature is used by the Mail program and normally appended
        to outgoing mail.

        Modify accordingly.

    UULIB:Seq

        The Seq file should exist but otherwise not be modified by
        the user (except for setting it to a "1" once a year).  This
        file is atomically updated and used to provide unique filenames
        and mail IDs for outgoing mail.

    UULIB:Security

        This file contains a list of allowed directories remote UUCP
        transfers may read and write to.  Refer to the Security manual
        page.  This file never contains the UUSPOOL: directory which
        is implicitly read-write.

        You need not modify this file now but should keep it in mind.
        It protects your system in as much as I have been able to
        close the loopholes.  Loopholes might still exist.

    UULIB:news.distribution

        This file contains a list of news distribution idents for
        various areas and must normally be modified according to
        where you are.. you need to be a UUCP guru to do this.  Most
        people can just leave it alone.

    UULIB:Config

        This file contains configuration information for many
        executables in UUCP:C and should be modified accordingly.

        Be sure you modify at least the following entries.    REFER TO
        THE 'Assigns' MANUAL PAGE.

        NodeName
        UserName
        RealName
        NewsFeed    (not required if you don't care about news)
        Organization
        TimeZone
        DefaultNode
        Editor

        **** Take some time to pick a node name for yourself.  It
         should be no more than 8 characters long.  Some UUCP sites
         barf at node names longer than 6 chars so if you are not
         sure of your neighbors pick one no more than 6 characters
         long.    Your site name should be in lower case.

    UULIB:L.Sys

        This file contains site information for sites that may call
        you up or you may call up.

        You must modify this file appropriately before you can run UUCP,
        refer to the 'L.Sys' manual page.

    UULIB:Aliases

        This is a mail aliases file with aproximately the same
        power as /usr/lib/aliases on UNIX systems.    You should
        refer to the 'Aliases' manual page and modify this file as
        appropriate for various defaults like 'postmaster'... to
        whatever user name you pick for yourself.

    UUCP:S/Crontab

        This is a functional Crontab file for use with the DCron program.
        This file is normally moved to S: (it is useless in UUCP:S).

    UUSPOOL:LOGFILE

        UUCICO and other programs log errors and other things to
        this file.    Normally you use DCron to clean up this and
        other log files once daily to keep them from getting to large.


    (8)     TESTING / DMAIL

    You will next want to test your UUCP configuration.  If testing
    with a friend's Amiga running the same distribution simply
    email to him, then one of you run uucico -s<remotesystem>
    just like in QuickSetup.DOC, except this time you are using
    the system name he picked instead of 'test1' or 'test2'.

    If the initial tests in QuickSetup.DOC worked and the system
    is not working now check the following (common problems):

        (a) the login and password in your L.Sys file (that uucico uses
        to login to the remote machine) matches the login and
        password in the remote machine's Getty:Passwd file.

        (b) There is an entry for your node in the remote machine's
        L.Sys file and vise versa

        (c) The telephone number is correct

        (d) the node names are all in lower case

        (e) you constructed the email address correctly (nodename!user)

    I suggest you get UUCP running with a friend before getting it
    running with a UNIX system as it is easier to test it with a
    friend.

    Assuming you email to the user name he picked for his UULIB:Config
    'UserName' entry and he did the same thing to you, entering
    'dmail' without any arguments will bring up the mail shell
    and allow you to read the message after transfer via UUCico
    is complete.  You can check that the email actually arrived
    into the right mail box in UUMAIL: by simply getting a directory
    of UUMAIL:

    READ the manual page for DMail for information on the
    construction of mail paths to other systems and users.
