  Linux HAM-HOWTO, Amateur Radio.
  Terry Dawson, VK2KTJ, 94004531@postoffice.csu.edu.au
  v1.9, 21 November 1995

  It is hoped that this document 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 consequence
  of this information being available that more amateur radio operators
  will choose Linux as the platform of choice for their experimentation,
  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.  This document also
  provides some detailed information on how to configure and install
  some of the more important pieces of software.

  1.  Introduction.

  This list was prompted by comments that had been expressed in the
  various Linux newsgroups about the number of amateur radio operators
  that were involved with Linux. It is now clear that Linux is becoming
  a popular platform for Amateur Radio development work.

  This list was originally called the RADIOLINUX list, but has been
  moved into the Linux Documentation Project HOWTO collection, so it has
  been renamed the HAM-HOWTO. I make no apologies for the name.

  3.2.  SatTrack - Satellite tracking program


     Name
        SatTrack

     Author
        Manfred Bester, DL5KR, manfred@ssl.berkeley.edu, (510) 849-9922

     Description
        Satellite realtime tracking and orbit prediction program with
        X11 color graphics.

     Status
        Version 3.1 has been released.

     System requirements
        A vt100 terminal and or X11 server. A Maths Coprocessor is
        useful, but not essential, for good performance.

     Detail
        SatTrack is a satellite tracking program that has been written
        in 'C' language on a UNIX workstation. It provides two different
        live displays, for single or multiple satellites, and two
        different orbit prediction facilities. Cursor controls used in
        both live displays are compatible with the VT100 standard, which
        allows the program to be run basically from any terminal. An
        optional X Window graphics display shows the typical world map
        tracking chart. The orbit prediction can be run either
        interactively or in a batch mode. In the latter case all
        necessary parameters are specified on the command line. The
        program uses the NORAD/NASA two-line Keplerian element (TLE)
        sets directly.

        The current version of SatTrack can track a single satellite
        and/or display multiple satellites for a single ground station.
        It also can control suitable ground station hardware, like
        antennas and radio equipment, and has an autotrack mode in which
        it switches automatically between a number of specified
        satellites. For calibration purposes tracking of the Sun and the
        Moon are also provided. Future releases will provide more
        options. SatTrack requires about 5 MB of disk space in the full
        distribution with eight different world maps (2 styles, with 4
        different sizes each, to fit everyone's screen and taste) and
        less than 1.5 MB of memory at run time. More information can be
        obtained from the SatTrack WWW Home Page
        <http://www.primenet.com/~bester/sattrack.html>

        Compiling the software under Linux is quite straightforward.
        Manfred has designed the Makefile to compile the software
        directly under your home directory, this is easy to change.

        The steps I took were:


          # cd /usr/src
          # export HOME=/usr/src
          # gzip -dc sattrack-3.1.1.tar.gz | tar xvf -
          # cd SatTrack/src
          # vi Makefile
            {Comment SUN4 compile options}
            {Uncomment the linux options}
            {Select the options you want}
          # make





     Where and How to obtain it.
        SatTrack can be found at: ftp.amsat.org
        <ftp://ftp.amsat.org/amsat/software/Linux/sattrack-3.1.1.tar.gz>
        or ftp.jvnc.net

        iialan@iifeak.swan.ac.uk

     Description
        Software that provides native AX.25 support in the Linux Kernel.

     Status
        ALPHA. Still under development. In a working state.

     System requirements
        Linux kernel 1.3.*, or kernel 1.2.* plus patches.

     Detail
        Jonathon'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.
        Jonathon has recently added NetRom support and provided fixes
        and other enhancements to the code.  The software comes in two
        parts, a kernel patch, and the configuration tools and user
        programs. The user programs included in the most recent
        distribution are:

        axassociate
           to associate a particular AX.25 callsign with a userid on
           your system.

        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
           generated beacon messages every 30 minutes.

        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 packet trace tool for radio links.

        mheard
           a program to display callsign heard on radio ports.

        netromd
           a daemon program to generate netrom routing broadcasts.

        noderest
           a program to restore netrom routing information from a file.

        nodesave

        California Berkeley.





  5.2.  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
        Brandons code was rolled back into the main jnos distribution,
        so development on the two runs in parallel.

     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 slip).

     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.

     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/jnos/jnos110i.zip>
        ncurses is available on most Linux ftp sites.

     Licensing/Copyright
        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.

     Description
        TNOS is a NOS derivative that is being actively supported and
        which is available for both DOS and Linux. It features
        enhancements not found in other NOS versions.

     Status
        The current version is 2.0 and is stable.

     System Requirements
        Kernel networking slip support if you want to link the normal
        Linux network facilities with TNOS. A kiss tnc.

     Detail
        Brian maintains a World Wide Web server which contains up to
        date information on TNOS, you can find it at www.lantz.com
        <http://www.lantz.com/tnos/tnos.html>.

     Where and how to obtain it

  5.4.  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.

     Licensing/Copyright
        Copyright by Bob Arasmith, N0ARY, but freely redistributable.

  5.6.  Packet Cluster Node software


     Author
        Franta Bendl, DJ0ZY, and Bernhard ("Ben") Buettner, DL6RAI,
        root@dl6rai.muc.de

     Description
        A PacketCluster like system running on Linux.

     Status
        Released in October 1995.

     System Requirements
        Linux Kernel version 1.2.0 or greater with Alan Cox's AX.25
        version 025 driver, TCP/IP networking, SysV IPC. Also needs Perl
        and KISS TNC hardware on serial device.

     Detail
        PacketCluster nodes have been available for about six years. The
        original software was written by Dick Newell, AK1A, and is
        running under DOS.  clx is a system which clones a PacketCluster
        node. To the outside user commands and features are mostly
        identical, remote PacketCluster nodes, which can be networked,
        don't see the difference between a generic PacketCluster node
        and clx. So it fits well into an established network of
        PacketCluster nodes.

        clx is not a user application, it is network node software. As
        such it is not of much use for the individual amateur. SysOPs of
        PacketCluster nodes with some experience on both PacketCluster
        and Linux will find this application interesting.

        Here are some of the features of CLX:


     o  It is fully compatible with the internal PCxx protocol and from
        a users' point of view. It allows multitasking and different
        priorities for different things.


     o  The software detects looping DX spots without generating endless
        messages. clx filters out such duplicate information. We have
        implemented a concept which allows us to connect the network at
        multiple points, which would formerly have been called a
        "Cluster Loop". clx knows of so-called "active" and "passive"
        links. The outcome is that more DX information is seen by clx.

     o  An interface to call your external programs (even dialog
        programs).

     o  clx uses modern programming concepts like shared memory for
        common data, lex & yacc to implement command language, shared
        libraries to keep binaries small (this is still on our wish
        list), remote procedure calls for inter process communication.
        It is strictly modularized with its own dedicated process for
        every major task.

     o  Comprises the following modules:

        con_ctl
           interfaces AX.25 kernel code and provides a socket for local
           users.

        rcv_ctl
           manages receive spooling.

        snd_ctl
           manages transmit spooling.

        rm_disp
           receive message dispatcher, forwards messages to other
           processes.

        usr_req
           user database requests, forks a process for every database
           task to make it run in the background. The background process
           later sends the results directly to send_ctl.

        mb_ctl
           mailbox control. The mailbox keeps messages in a file system,
           header information is stored in the database.

        usr_ctl
           user administration (logins, logouts, logbook).

  5.8.  TNT.


     Author
        Mark Wahl, DL4YBG, DL4YBG @ DB0BLO.#.DEU.EU, wahlm@zelator.de

     Description
        A Hostmode terminal program for TNC's that support the WA8DED
        hostmode protocol.

     Status
        Version 0.8 is reportedly stable.

     System requirements
        TNC supporting WA8DED hostmode protocol, serial line.

     Detail
        TNT is a full featured hostmode terminal program. Compiling it
        on Linux is as difficult as untarring the source and typing
        `make'. It provides both a `dumb' terminal and X11 version. It
        comes with some comprehensive documentation which describes its
        features in some detail. Its main features are:

        Multiple sessions:
           TNT supports multiple packet radio connections on virtual
           screens that you can switch between. Each session window
           provides split screen (seperate transmit and receive text)
           operation with a status line. Commands can be entered in
           either a command session, or in any terminal session using a
           command key. Each of the virtual screens can be larger than
           the physical screen and can be scrolled around.

        Data capture, file transfer and logging:
           A number of options are available for logging received text
           to files. You can log transmit, receive or both to a log
           file. You can overwrite or append received data to existing
           files. You can use the `autobin' protocol to transmit or
           receive binary files.

        Remote Shell operation:
           You can provide a shell to remote users so that they can
           access other programs on your computer. You can also run a
           program and direct its input/output to a channel so that
           users can use it.

        Redirection of devices to a channel:
           TNT allows you to redirect input/output from a channel to a
           device, a modem for example.

        Umlaut conversion:
           TNT provides umlaut conversion if necessary.

        Remote mode:
           Remote users can issue command themselves if allowed to do
           so.

        Socket mode:
           You can configure tnt so that it opens a socket for users to
           telnet to that allows them operation just as you have from
           the console. This is useful where your linux machine is on an
           ethernet and you want other terminal on the net to have use
           of your radio.


     Where and How to obtain it.
        The software is available by anonymous ftp from: ftp.funet.fi
        <ftp://ftp.funet.fi/pub/ham/unix/packet/tntsrc09.tgz>. This site
        is mirrored at a number of places so you will probably find it
        at other places as well.

  5.9.  IPIP encapsulation daemon.


     Name
        Mike Westerhof's IPIP encapsulation daemon.

     Author
        Mike Westerhof KA9WSB (original code), then Bdale Garbee N3EUA
        (port to BSD), then Ron Atkinson N8FOW and John Paul Morrison
        (port to Linux), then Bdale rolled it all back together again.

     Description
        A daemon that will allow you to use your linux machine as an
        IPIP encapsulating gateway.

     Status
        Ron is running this code himself, and the other version have
        been run quite successfully.

     System requirements
        KISS TNC, any version of Linux supporting RAW sockets.

     Detail
        If you've ever used an internet gateway from your amateur packet
        radio you have probably been connected by an encapsulation
        gateway of some descpription. Most run KA9Q's NOS and DOS, but
        others run Unix and this daemon. It allows you to encapsulate IP
        within IP, so that you can 'tunnel' IP connections over the
        Internet. The software allows you to connect a KISS TNC to your
        linux machine and to have all datagrams received on it carried
        across the Internet to a similar gateway. Bdale has installation
        instructions in the package.

     Where and How to obtain it.
        This software is available from the col.hp.com
        <ftp:///col.hp.com/hamradio/packet/etc/ipip/ipip.tar.gz> ftp
        site.

     Licensing/Copyright etc.
        Freely distributable, though Bdale asks that if you use the code
        and like it you might send him a QSL card or a postcard.

  5.10.  AXIP encapsulation daemon.


     Name
        Mike Westerhof's AXIP encapsulation daemon.

     Author
        Mike Westerhof KA9WSB, ported to Linux by Ron Atkinson N8FOW.
     Description
        A daemon that will allow you to use your linux machine as an
        AXIP encapsul ating gateway.

     Status
        Not properly tested, but assumed to work ok.

     System requirements
        KISS TNC, any version of Linux supporting RAW sockets.

     Detail
        This daemon is the partner to the IPIP encapsulation daemon. It
        allows you to encapsulate AX.25 frames in IP to carry them
        across the Internet. This is useful for linking AX.25 networks
        in remote areas. Ron has supplied a Makefile for linux, and with
        it the software compiled without errors on my system running a
        recent version kernel. Ron has also written some README files
        which give you the detail necessary to compile the system and
        the original documentation describes how to configure it.

     Where and How to obtain it.
        This software is available in the sunsite.unc.edu ham apps
        directory
        <ftp://sunsite.unc.edu/pub/Linux/apps/ham/ax25ip.tar.gz>.

     Licensing/Copyright etc.

     Name
        mkiss

     Author

     Description
        a program that will allow you to make use of the feature of
        multidrop kiss mode tncs.

     Status
        stable, released.

     System requirements.
        A modern linux kernel and AX.25 kernel support.

     Detail
        The existing KISS support in the linux kernel is designed for
        simple single channel KISS TNC's. A number of TNC's support what
        is called multidrop mode where a single TNC may support a number
        of modems, each being controllable via an individual KISS port
        across the same serial interface. Kevin has overcome the lack of
        multidrop support by writing a program that takes two seperate
        kiss feeds from the kernel and combining them into a single
        multidrop feed which it passes to the tnc. The reverse process
        also takes place where it splits the single multidrop feed into
        the appropriate individuals feeds.

        Instructions on how to compile, install and use the software
        come in the package.

     Where and How to obtain it:

  6.1.  GW4PTS Morse trainer.


     Author
        Alan Cox, GW4PTS, iialan@iifeak.swan.ac.uk

     Description
        A Morse Code trainer that uses the PC internal speaker

     Status
        stable, works quite well, unfinished.

     System requirements
        Linux, any version

     Detail
        Alan wrote this small program in only an hour. It is quite neat,
        and allows you to play morse at a range of speeds and
        frequencies through the PC internal speaker. You can specify the
        text to be played either from the command line, from a file, or
        the program is capable of generating random character groups. As
        it stands you must invoke the program from a Linux Virtual
        Console, as it relies on certain kernel calls to produce the
        sound, and these don't work as easily from an XTerm. As it
        sounds each character it lists the character in verbal form (Di,
        Dit, Dah etc.) to the screen. Alan is hoping that someone will
        take the code and enhance it with the features he has listed in
        the comments at the head of the source file.

     Where and How to obtain it.
        I've had a large number of responses from people seeking this
        code, so I've obtained Alan's permission to make it available.
        You can obtain it from sunsite.unc.edu

        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
        <ftp://sunsite.unc.edu/pub/Linux/apps/circuits/irsim-9.2.linux.1.tar.gz>.
