Linux Amateur Radio Software List
|
||||
Terry Dawson, VK2KTJ, terryd@extro.ucc.su.oz.au
|
||||
v1.2 04/09/94
|
||||
|
||||
It is hoped that this list will assist Amateur Radio operators in
|
||||
finding and trying the various amateur radio software that has been
|
||||
written for, or ported to Linux. It is also hoped that as a conse-
|
||||
quence of this information being available that more amateur radio
|
||||
operators will choose Linux as the platform of choice for their exper-
|
||||
imentation, and that software developers will choose Linux as the
|
||||
platform for their software development, further expanding the role of
|
||||
operating systems like Linux in the Amateur Radio field.
|
||||
|
||||
1. Introduction.
|
||||
|
||||
This is the second release of this list. The list was prompted by
|
||||
comments that had been expressed in the various Linus newsgroup about
|
||||
the number of amateur radio operators that were involved with Linux.
|
||||
It seemed to me that I was catching snippets of information here and
|
||||
there relating to development efforts taking place, but I never really
|
||||
knew where to locate either the person responsible for a particular
|
||||
piece of software, or the software itself. The list is quite small
|
||||
with only a few entries, but I'm hoping that people will contribute to
|
||||
the list as new software becomes available. I feel though that the
|
||||
items listed are an excellent base to build on, as they represent the
|
||||
various ways in which software can be developed for Linux for use in
|
||||
Amateur Radio.
|
||||
|
||||
I'd originally considered limiting the scope of this list to non-
|
||||
commercial software only, but have subsequently changed my mind.
|
||||
Taking a serious look at most amateur radio fields shows that most
|
||||
good developments are those that are designed by individuals and that
|
||||
commercial entities have taken up and disseminated to the mass market.
|
||||
I'd like to see the same happen for Linux support for Amateur Radio
|
||||
software too.
|
||||
|
||||
|
||||
2. Contributions/Updates etc.
|
||||
|
||||
I'd like for this list to be as complete and up-to-date as possible.
|
||||
So I'm keen to hear about any developments or products that I don't
|
||||
already know about, or that the entry is obselete or outdated for.
|
||||
|
||||
What I'd like as a minimum set of requirement would be something like
|
||||
the following:
|
||||
|
||||
|
||||
Name
|
||||
The name of the software in question.
|
||||
|
||||
Author
|
||||
Who wrote, or ported the software. An email address, or some
|
||||
other means of contacting them is also essential.
|
||||
|
||||
Description
|
||||
A single line description of what the software does.
|
||||
|
||||
Status
|
||||
An indication of the software's status. Is it still in testing?
|
||||
Is it a production release? Is it still in the design stage?
|
||||
|
||||
System requirements
|
||||
What does the software require to run? Does it require X-
|
||||
Windows? Does it need a soundcard? Does it need a certain
|
||||
version of kernel? Does it need other software to support it?
|
||||
|
||||
Detail
|
||||
I'm not keen on including a large amount of detail on each piece
|
||||
of software as this would consume a lot of time reading and
|
||||
trying to keep up to date. So instead what I'd like to list is
|
||||
what makes this software unique, anything special about it.
|
||||
Perhaps its most outstanding features, that sort of thing.
|
||||
|
||||
Where and How to obtain it.
|
||||
If the software is freely distributable then ftp details would
|
||||
be great. If it is commercial software then the name of the
|
||||
company distributing the software, and an address or telephone
|
||||
number. If it is available only by some other means, say mail
|
||||
order, then details on where and how to obtain it.
|
||||
|
||||
Licensing/Copyright etc.
|
||||
Is the software Copyleft? Copyright? Shareware? Public Domain?
|
||||
Restricted in use in any way?
|
||||
|
||||
Don't worry if you don't know all of these details, just send me what
|
||||
you do know and I'll list what I can. I'd rather have an incomplete
|
||||
listing than no listing at all.
|
||||
|
||||
Please mail any contributions to:
|
||||
|
||||
terryd@extro.ucc.su.oz.au or terry@orac.dn.itg.telecom.com.au
|
||||
|
||||
I'd list a packet radio address too but I'm not properly operational
|
||||
again yet after moving house.
|
||||
|
||||
|
||||
3. Discussion relating to Amateur Radio and Linux.
|
||||
|
||||
There are various places that discussion relating to Amateur Radio and
|
||||
Linux take place. They take place in the comp.os.linux.* newsgroups,
|
||||
they also take place on the HAMS list on niksula.hut.fi. Other places
|
||||
where they are held include the tcpgroup mailing list at ucsd.edu (the
|
||||
home of amateur radio tcp/ip discussions), at Club meetings and on-air
|
||||
of course.
|
||||
|
||||
To join the Linux HAMS channel on the mail list server, send mail to:
|
||||
|
||||
|
||||
linux-activists@niksula.hut.fi
|
||||
|
||||
|
||||
|
||||
|
||||
with the line:
|
||||
|
||||
|
||||
X-Mn-Admin: join HAMS
|
||||
|
||||
|
||||
|
||||
|
||||
at the top of the message body (not the subject line).
|
||||
|
||||
To join the tcpgroup send mail to:
|
||||
|
||||
|
||||
listserver@ucsd.edu
|
||||
|
||||
|
||||
|
||||
|
||||
with the line:
|
||||
subscribe tcpgroup
|
||||
|
||||
|
||||
|
||||
|
||||
in the body of the text.
|
||||
|
||||
Please remember that the tcpgroup is primarily for discussion of the
|
||||
use of advanced protocols, of which tcp/ip is one, in Amateur Radio.
|
||||
Linux specific questions should not go there.
|
||||
|
||||
|
||||
4. Where to obtain new versions of this list.
|
||||
|
||||
This list will be periodically posted to the comp.os.linux.announce

|
||||
Description
|
||||
Software that allows the Linux Kernel to perform AX.25
|
||||
networking.
|
||||
|
||||
Status
|
||||
ALPHA. Quite stable though.
|
||||
|
||||
System requirements
|
||||
Linux kernel 1.0 or later.
|
||||
|
||||
Detail
|
||||
Alan's software provides the programmer with a berkeley socket
|
||||
based interface to the AX.25 protocol. AX.25 sockets can opened
|
||||
for either connected, or connectionless modes of operation.
|
||||
Support to allow tcp/ip over AX.25 is provided. The user
|
||||
applications has been Jonathon G4KLX. The software comes in two
|
||||
parts, a kernel patch, and the user programs. The user programs
|
||||
included are:
|
||||
|
||||
axadd
|
||||
to manipulate the AX.25 ARP table.
|
||||
|
||||
axattach
|
||||
to convert a serial device into a KISS device.
|
||||
|
||||
axl
|
||||
an AX.25 listener designed to start a PMS when it receives an
|
||||
incoming connection. The PMS is still very new.
|
||||
|
||||
axsetcall
|
||||
to change the callsign of a port.
|
||||
|
||||
beacon
|
||||

|
||||
|
||||
call
|
||||
A linemode AX.25 connection program. Call allows you to make
|
||||
connections to other AX.25 nodes. It provides file transmit
|
||||
and receive capabilities, and newer versions allow YAPP
|
||||
binary file transfers.
|
||||
|
||||
listen
|
||||
a demonstration of how to use intercept AX.25 frames at the
|
||||
raw packet level. Useful as a building block for packet
|
||||
tracing for example.
|
||||
|
||||
Where and How to obtain it.
|
||||
There are a number of different versions of the software. You
|
||||
must choose the one that suits your version of Linux kernel. The
|
||||
software is available from: sunacm.swan.ac.uk
|
||||
(ftp://sunacm.swan.ac.uk/pub/misc/Linux/Radio/)
|
||||
|
||||

7.2. JNOS
|
||||
|
||||
|
||||
Author
|
||||
Brandon Allbery, KF8NH, bsa@kf8nh.wariat.org
|
||||
|
||||
Description
|
||||
Brandon ported JNOS to Linux. His port is currently of the 1.09
|
||||
(aka 1.08df) release of JNOS. Future versions will probably be
|
||||
based on Doug Crompton's evolution of 1.08df. Brandon suggests
|
||||
that JNOS for Linux is primarily of interest to people with
|
||||
existing DOS-based NOS configurations (especially server/switch
|
||||
configurations) who wish to switch to Linux or to escape the
|
||||
640K barrier.
|
||||
|
||||
Status
|
||||
The current version is ALPHA.4. Brandon is still tracking down
|
||||
bugs, as well as evolving new features.
|
||||
|
||||
System Requirements.
|
||||
Any version of Linux along with ncurses 1.8.1 or 1.8.5 (the
|
||||
latter is preferred). Optionally you will require Linux
|
||||
networking (at least loopback) and slattach (kernels pre-1.1.13
|
||||
or post-1.1.20 required for this).
|
||||
|
||||
Detail
|
||||
If you include the Linux networking code in addition to JNOS,
|
||||
you can link the two by a slip link running over a pty, so that
|
||||
Linux can provide services to your radio users. In this way you
|
||||
can easily add servers without having to build them into JNOS
|
||||
itself. Brandon has supplied the following list of known bugs:
|
||||
|
||||
o some servers seem to be causing unexplained exits.
|
||||
|
||||
o PPP is reported not to work in ALPHA.4, although it worked in
|
||||
ALPHA.3.
|
||||
|
||||
o BBS forwarding when convers is compiled in but not configured
|
||||
causes core dumps.
|
||||
|
||||
o the finger server is getting bad filenames.
|
||||
|
||||
o the bbs W command is case-munging filenames.
|
||||
|
||||
Where and How to obtain it.
|
||||
You can obtain JNOS for Linux ALPHA.4 at: ftp.ucsd.edu
|
||||
(ftp://ftp.ucsd.edu/hamradio/packet/tcpip/linux/j109lxA4.tgz)
|
||||
ncurses is available on most Linux ftp sites.
|
||||
|
||||
Licensing/Copyright etc.
|
||||
Brandon's modifications to JNOS are public domain. Most of the
|
||||
pre-existing NOS code is copyrighted and restricted to non-
|
||||
commercial use by the various contributors from Phil Karn on.

7.3. N0ARY Packet BBS for UN*X
|
||||
|
||||
|
||||
Author
|
||||
Bob Arasmith, N0ARY, ported to Linux (and others) by Bob Proulx,
|
||||
KF0UW, rwp@fc.hp.com
|
||||
|
||||
Description
|
||||
A packet bbs implemented under UN*X.
|
||||
|
||||
Status
|
||||
ALPHA. Bob is running version ARY-0.9 on both Linux and HP-UX.
|
||||
The next version from N0ARY which is called 4.0 is in alpha
|
||||
test/development release. Bob has not been able to bring this
|
||||
online yet and is still running 0.9+kf0uw mods. Bob has about
|
||||
half it working with Alan Cox's AX.25 kernel which would be the
|
||||
desirable combination.
|
||||
|
||||
System Requirements.
|
||||
Linux installation, C Compiler, plus HAM radio TNC hardware.
|
||||
|
||||
Detail
|
||||
This bbs has an excellent packet user interface. It has a
|
||||
compatible set of commands with the RLI bbs so users will be
|
||||
familiar with it immediately. It then extends the command set
|
||||
to be a very nice natural language style interface (e.g "list at
|
||||
allus about KPC-3"). Many csh style bang commands are supported.
|
||||
Also included is a mail interface to provide a packet to
|
||||
internet gateway.
|
||||
|
||||
Currently you need to customize the source code for your
|
||||
installation so you need some C programming proficiency.
|
||||
|
||||
Where and How to obtain it.
|
||||
For a Linux version or for Linux information send mail to
|
||||
rwp@fc.hp.com. For a SunOS version contact bob@arasmith.com.
|
||||
This code is not packaged for distribution yet since it is not
|
||||
past the alpha stage of development.

|
||||
|
||||
Description
|
||||
Scope is a simple software emulation of an oscilloscope. It
|
||||
graphically displays voltage as a function of time.
|
||||
|
||||
Status
|
||||
ALPHA. First release.
|
||||
|
||||
System requirements
|
||||
Sound card with input capability supported by the kernel sound
|
||||
driver. SVGALIB is used to do the display work.
|
||||
|
||||
Detail
|
||||
Scope uses the /dev/dsp device to take audio in from the
|
||||
soundcard and displays it on the screen in a manner similar to
|
||||
an oscilloscope. Jeff claims Scope was written more for
|
||||
amusement value than for any serious purpose.
|
||||
|
||||
Where and How to obtain it.
|
||||
You can obtain source, makefile and man page for Scope from:

An event-driven logic-level simulator for MOS circuits
|
||||
|
||||
Status
|
||||
Version 8.6, production.
|
||||
|
||||
System Requirements
|
||||
X-Windows.
|
||||
|
||||
Detail
|
||||
irsim is an X11 based simulator for MOS circuits. It has two
|
||||
simulation modes, either switch where each transistor is
|
||||
modelled as a voltage controlled switch, or linear where each
|
||||
transistor is modelled as a resistor in series with a voltage
|
||||
controlled switch, and each node has a capacitance.
|
||||
|
||||
Where and How to obtain it.
|
||||
You can obtain irsim from: sunsite.unc.edu

15.1. SunClock

Author

John Mackin, john@cs.su.oz.AU
|
||||
|
||||
Description
|
||||
A clock that will show you instantly what parts of the globe are
|
||||
exposed by sunlight and what parts aren't.
|
||||
|
||||
Status
|
||||
Released.
|
||||
System requirements.
|
||||
X-Windows.
|
||||
|
||||
Detail
|
||||
sunclock is another of those desktop gadgets that most people
|
||||
think look nice but really don't have a lot of use for. I use
|
||||
sunclock to obtain an at-a-glance indication of the time
|
||||
anywhere in the world. In its iconic form it sits in a small
|
||||
Mercator projection. When maximised it produces the same image
|
||||
but obviously larger with slightly more detail. It also
|
||||
displays the date, local time and UTC. sunclock actually
|
||||
calculates mathematically what parts of globe are sunlit and
|
||||
which aren't, it seems quite accurate, so long as you assume the
|
||||
earth has no atmosphere.
|
||||
|
||||
Where and How to obtain it.
|
||||
I haven't seen any precompiled sunclock binaries for Linux
|
||||
about, so check your nearest archie server. sunclock compiled
|
||||
straight out of the box for me.

||||

||||

15.2. Xearth

Author

Kirk Lauritz Johnson, tuna@cag.lcs.mit.edu, modified by Dimitris
|
||||
Evmorfopoulos, devmorfo@cs.mtu.edu.
|
||||
|
||||
Description
|
||||
A rotating earth for X-windows root window. It has real life
|
||||
shading, and options for geostatic view, and non geostatic view.
|
||||
A prettier and more modern version of sunclock but requires a
|
||||
bit more processing power.
|
||||
|
||||
Status
|
||||
released, stable.
|
||||
|
||||
System requirements.
|
||||
X-Windows.
|
||||
|
||||
Detail
|
||||
xearth is much like sunclock except that it draws a view of the
|
||||
earth onto your root map in blue and green, as the earth would
|
||||
be viewed from space. You have a number of options in
|
||||
determining the behaviour of the view. You can either have it so
|
||||
that the same part of the earth is displayed, and the sun
|
||||
rotates, so you'll have varying light and shadow on the display,
|
||||
or you can have it shown as if you were travelling with the sun,
|
||||
so the whole of the globe is visible, and the earth rotates.
|
||||
You can specify the latitude/longtitude that will be the centre
|
||||
of the display. xearth is also capable of producing gif and ppm
|
||||
graphics output, so you can generate custom graphics of the
|
||||
globe. When run as your root map, you can adjust the interval
|
||||
of time between updates. On my 486SX25 you notice a small
|
||||
degradation in performance when it is recalculating, but it's
|
||||
not annoying.
|
||||
|
||||
Where and How to obtain it.
|
||||
A precompiled xearth binary is available from: sunsite.unc.edu,
|
||||
or the source can be obtained from just about any X11/contrib
|
||||
directory. Try export.lcs.mit.edu if you can't find it
|
||||
elsewhere.
