NOSintro-to-Demon Conversion Guide
==================================
by Ian Wade <ian@dowrmain.demon.co.uk>
May 1995
Intended Readership
-------------------
This Guide is intended for readers of "NOSintro" who want to use
KA9Q "NET" to access the Internet via the "Demon" Internet
Service Provider.
============
Introduction
============
"NOSintro" is a fully illustrated 356-page book for beginners to
the KA9Q Network Operating System, describing in detail how to
configure the software and get it running on a DOS PC.
"NOSintro" specifically covers the workings of KA9Q in a packet
radio environment. However, most of the book is also directly
applicable to the Demon Internet dial-up environment as well.
This short "NOSintro-to-Demon Conversion Guide" outlines the main
differences between the two environments, and explains how to
read "NOSintro" with Demon dial-up in mind.
Details of where to get a copy of "NOSintro" are included at the
end of this Guide.
---------
"DISview"
---------
You will find it useful to have a copy of the "DISview" Reference
Documentation Package to hand when reading "NOSintro". "DISview"
is a complete reference work containing details of every command
in Demon's version of KA9Q "NET", with full command syntax and
parameter information and hundreds of examples.
"DISview" also contains documentation on setting up the mail
alias files, ftpusers, etc (a source of much confusion to
beginners), and how to set up some of the less well-known
facilities (such as the built-in DNS name server, dial-up scripts
and IP address filtering for firewalls).
You can download "DISview" via FTP from ftp.demon.co.uk. Look in
the directory /pub/disview for the files 'disview.txt' and
'disvw518.zip'.
===============
"NET" and "NOS"
===============
The KA9Q system comes in many guises, and there are now many
different implementations in use throughout the world. KA9Q is
the radio callsign of Phil Karn in the United States, and it was
Phil's pioneering work in the mid 1980s that resulted in the
development of the "NET" TCP/IP package for packet radio
networks. Other developers subsequently produced new versions of
"NET" called "NOS" ("Network Operating System"), again mostly for
packet radio.
Demon Internet Ltd then came on the scene in 1992, with a
modified version of "NET" suitable for use on dial-up telephone
networks. Demon's "NET" is essentially the same as the packet
radio versions, with most of the radio-specific components
stripped out and with additional features to make it easier to
configure and use.
For all practical purposes, the terms "NET" and "NOS" mean the
same thing -- in fact, some of the documentation that is
generally available uses both "NET" and "NOS" interchangeably in
the same document.
======================
What "NOSintro" Covers
======================
The book "NOSintro" describes how to set up and use the KA9Q
Network Operating System in a packet radio environment.
"NOSintro" is a practical, "hands-on" book, liberally illustrated
with over 80 line drawings showing how everything fits together,
together with countless examples of keyboard commands and file
layouts.
The book covers the following topics:
## Installing the software
## Descriptions of all the software control files (ftpusers etc)
## A summary of the principal protocols.
## The meaning of network domains, names and addresses in a
packet radio environment, and the organisation of the DNS
cache file domain.txt.
## The concepts of client/server.
## How to configure and use FTP, Telnet, SMTP Mail, POP Mail,
Ping, Hop, Chat, TIP and IP routing.
## How to configure and use the built-in KA9Q Bulletin Board
System (BBS), both for standard operation and for remote
control operation.
## How to configure and use a Terminal Node Controller (TNC) --
a TNC is the packet radio equivalent of a modem.
## How to configure and use the SLIP interface.
## How to configure and use external Clarkson/Crynwr packet
drivers for LAN support.
## How to configure and use packet radio protocols (AX.25,
NET/ROM, PBBS, KISS).
The Appendices contain example listings of all the "NOS" control
files, a Command Set Reference Guide, plus other useful reference
information, and the book closes with a very comprehensive 14-
page index.
==============================
What "NOSintro" does NOT Cover
==============================
"NOSintro" was written before Demon became established, and
contains only limited coverage of packages external to KA9Q
"NET". For example, PCElm and similar mailers are only briefly
mentioned (although information on how they fit into KA9Q is
included). Also, there is no mention of USEnet news readers such
as SNEWS, and modem setup details concentrate on packet radio
modems rather than telephone dial-up modems.
Other features added by Demon to "NET" but which are not
described in "NOSintro" include the following commands: at,
ftpopt, inline, ppp, rlogin, rsh and time.
That said, all of these capabilities do receive extensive
coverage in Demon's own documentation, and also in the "DISview"
Reference Documentation Package and the various FAQ help files in
the "demon.answers" newsgroup.
====================================
What to skip when reading "NOSintro"
====================================
When reading "NOSintro" from a Demon dial-up point of view, you
can safely skip these topics:
## The "NOSview" documentation package (the "DISview" package
described earlier replaces it).
## The KISS, AX.25, AXIP, NET/ROM, NRS, RSPF and PBBS protocols.
## Terminal Node Controllers (TNCs).
## The ELM and BM mailers.
## The following KA9Q files: net.rc, netrom.sav, popusers, seqf,
kisson.dia, tncreset.dia, tncreset.scr and forward.bbs.
## The following KA9Q commands: attended, autoroute, ax25,
bootp, bootpd, cls, comm, connect, drsistat, dump, eaglestat,
etherstat, ftype, hapnstat, hs, info, lock, lzw, mail, mode,
motd, netrom, nrstat, pop, popmail, rarp, rspf, sccstat,
status, tail, third-party, ttylink and watchdog.
## CTRL-B for command recall.
## Password control for accessing the built-in BBS using the
remote sysop command ("@").
=========================================
What to translate when reading "NOSintro"
=========================================
It will help your understanding if you mentally translate the
following when reading "NOSintro":
## For "Terminal Node Controller (TNC)" read "modem".
## For "radio" read "telephone line".
## For "radio callsign" read "network address"; e.g. an Ethernet
address like 02:00:24:a6:5b:50.
## For the packet radio network "AMPRnet" read "Internet". Also,
most of the examples of KA9Q commands containing Internet
addresses (e.g. 'ftp ns9ken') imply the default domain suffix
'ampr.org'. This is because almost all packet radio
communication takes place entirely within this domain. In the
Internet world accessed via Demon, you will normally need to
specify the full nodename (hostname + domain name) in KA9Q
commands.
## For "autoexec.nos" read "autoexec.net".
## For the interface name "tnc0" read "sl0".
## In "NOSintro", the ~/scripts subdirectory contains a number
of useful scripts for setting up the console function keys
and for controlling the TNC. In Demon's release of "NET",
~/scripts is a file that points to scripts in ~/spool/scripts
which run when making or breaking a PPP network connection.
## At the bottom left-hand corner of the diagram on page 144,
local mail is shown as being subject to processing by alias
but not by rewrite. In Demon's "NET", local mail is processed
by both (i.e. as just as the same as mail from a remote SMTP
client).
## "NOSintro" describes in detail how to use the POP protocols
(POP2 and POP3) for mail forwarding. Note however that
Demon's current release of "NET" does not support POP (a
special version is required if you subscribe to Demon's POP
option).
## Demon have added/modified/removed many KA9Q command
parameters. See "DISview" for the details.
========================
Amendments to "NOSintro"
========================
The following minor amendments apply:
## In the box "How to contact the author" on the publisher's
information page (facing the Contents page), remove the
AMPRnet and AX.25 Packet Radio addresses, and change the
Electronic Mail address to ian@dowrmain.demon.co.uk.
## Page 72, Fig 10-1 (bottom left): The ground pin on the 9-pin
connector should be pin 5 (not pin 9).
## Pages 130-140: The heading at the top of each page should
read "Hands On -- FTP".
## Pages 338-339: (for packet radio users only) The UK AMPRnet
IP Address Coordinator list is now well out-of-date. Contact
Paul Taylor, Brionys Patch, 13 Altona Road, Loudwater, High
Wycombe, Bucks HP10 9RW to get an up-to-date list.
