Linux HAM-HOWTO, Amateur Radio. Terry Dawson, VK2KTJ, terry@perf.no.itg.telecom.com.au v2.0, 30 April 1996 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. 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. 1.1. Changes from the previous version Additions: ObjectProDSP LBBS - maybe. Mike Westfall's ttylinkd Craig Small's ttylinkd predict, uo11, dove, kepgen - thanks John!

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 <ftp://ftp.jvnc.net/priv/kupiec/sattrack/sattrack-3.1.1.tar.gz> or the SatTrack WWW Home Page <http://ssl.berkeley.edu/isi_www/sattrack-3.1.1.tar.gz> Licensing/Copyright The software is Copyright of Manfred Bester.

Predict Author John A. Magliacane, KD2BD, <kd2bd@amsat.org> Description A satellite orbital prediction program that also tracks the sun's position to predict visible satellite passes. Status Complete and working. System requirements predict is a screen-oriented program that utilizes the ncurses-1.8.5 (or later) library. A color terminal is a plus, but not a necessity. Detail Features of predict include azimuth and elevation headings of satellite passes, orbital phase, sub-satellite point locations, slant ranges, orbit numbers, and sunlight visibility as a function of date and time. The program is simple, fast, and easy to use. Predict maintains an orbital database for 21 satellites that can be updated by the user through the keyboard or by using files containing NASA 2-line orbital element data. Since this program operates under a multiuser environment, each user on the system owns and maintains his or her own unique orbital data base. This program has been compiled using the highest level of compiler optimization for high speed execution, and uses an a.out binary format for greatest compatibility. To install the package use the following: # cd / # tar xvfz predict.tgz Where and How to obtain it.

Magliacane, KD2BD, <kd2bd@amsat.org> Description A simple, yet useful utility that generates Keplerian data files in the NASA 2-line format from data entered through the keyboard. Status Complete. System requirements kepgen is a screen-oriented program that utilizes the ncurses-1.8.5 (or later) library. A color terminal is a plus, but not a necessity. Detail kepgen allows the user to create checksummed Keplerian data files in the NASA 2-line format using orbital data entered via the keyboard. kepgen was created out of the need for generating 2-line orbital files from orbital data copied from WA3NAN audio transmissions during Space Shuttle missions. The files created can be read by virtually any satellite tracking or orbital prediction program. kepgen comes pre-compiled (a.out format) with a man page entry for ease of use. To install kepgen you should use the following commands: # cd / # tar xvfz kepgen.tgz Where and How to obtain it.

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. Contributed by: Brandon Allbery, KF8NH 5.2. TNOS Author Brian A. Lantz, brian@lantz.com 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 The current version of TNOS is always available from: ftp.lantz.com <ftp://ftp.lantz.com/tnos/current/linux/>, sunsite.unc.edu <ftp://sunsite.unc.edu/pub/Linux/apps/ham/>, or ftp.ucsd.edu <ftp://ftp.ucsd.edu/hamradio/packet/tcpip/tnos/>.

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. Contributed by: Bob Proulx, kf0uw, rwp@fc.hp.com 5.4. LBBS - Linux BBS message gateway Author Daryl L Miles, G7LED, dlm@frink.demon.co.uk Description A BBS package designed to operate with either the native AX.25 kernel code or with the Wampes package. Status In development, working. System requirements Kernel AX.25 support or the Wampes package. sendmail, CNEWS. Detail Daryl's aim was to build a platform on which amateurs could build a Packet BBS to smtp gateway for Linux. I'm not sure what the current status is as the last version I could find was dated 30 Jun 1995. The latest binary version supports: ╖ MBL, FBB batching, FBB compressed, FBB type 1 compressed forwarding with restart facility implemented, deferring, and rejection. ╖ various Linux transport mechanisms including TCP kernel, AX.25 kernel, Wampes NetROM, AX25 or TCP. ╖ Simple dialer, to allow connections through AX.25 or NetROM nodes. ╖ White Pages ╖ Transient handling of type A (ACK messages). ╖ SMTP/NNTP<>BBS gatewaying implemented heavily to the extent that the user front end will be accessing the NetNews spool to retrieve articles. ╖ Message filter mechanism ╖ Field swapping (like SWAPP.SYS in FBB). ╖ Multiuser/connect. To install, I did the following: # cd /usr/src # mkdir LBBS # tar xvfz LBBS-0.1.6A.tar.gz # cd LBBS # ./Install.sh This created a /usr/lbbs directory. The README.Setup file suggest an order in which to configure the BBS. Where and How to obtain it.

Author SM0OHI, pme@it.kth.se Description Software that will convert incoming MBL/RLI messages into either NNTP or RFC-822 formatted mail messages. Status Development, not yet released. System requirements Unknown. Detail This software would be ideally suited to those who want to establish a mail and news gateway between conventional tcp/ip networks and the amateur radio mail network. Where and How to obtain it. Not yet availale. Licensing/Copyright Unknown. Contributed by: SM0OHI 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: ╖ 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. ╖ 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. ╖ An interface to call your external programs (even dialog programs). ╖ 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. ╖ 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). usc_mng manages external user commands and command extensions. iu_com inter user communication (talk, conference). send_ctl transmit spooling, handling priorities. icl_com inter node communication (processing and generating PCxx messages). clx_ctl system administration, installing shared memory pages. int_com manages internal program communications. ╖ The following is the only application program which can be run on the console: loc_usr allows console operator(s) to log in like a normal user. Future enhance planned are: ╖ A console monitor to watch ongoing activities ╖ Speed optimization ╖ An internal clx protocol ╖ An additional command shell for experienced users Where and How to obtain it: ftp.funet.fi <ftp://ftp.funet.fi/pub/ham/unix/Linux/cluster> There are five files that make up the package: ╖ 00Index ╖ clx_200.tgz ╖ install.clx ╖ README Licensing/Copyright clx (c) by Franta Bendl (DJ0ZY) and is available for non- commercial use, but the authors want to keep track of who is using their product, so before you can actually use the software you have to ask for an encrypted callsign string to be placed in the configuration file. You must send mail to <clx_us@dl6rai.muc.de> to organise this. Contributed by: Bernhard ("Ben") Buettner, DL6RAI 5.7. Single floppy disk AX.25 router. Author Alan Cox, GW4PTS, iialan@iifeak.swan.ac.uk Description A single floppy disk version of linux with enough software to allow a PC to act as an AX.25/IP router. Status Development, not yet released. System requirements. As for any Linux system a 386SX class PC or better. Detail No detail yet. Where and How to obtain it. Not yet available. Licensing/Copyright Unknown/Undecided. 5.8. DPTNT Terminal and BBS package. Author Mark Wahl, DL4YBG, DL4YBG@DB0BLO.#.DEU.EU, wahlm@zelator.de Description A suite of programs that provide BBS and Terminal programs for Linux. Status Stable and working. System requirements TNC supporting WA8DED hostmode or KISS protocols. 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. DPBOX is a full featured BBS supporting the following features: ╖ F6FBB, W0RLI, TheBox style forwarding protocols. ╖ 8-bit transparent handling of messages using AutoBIN protocol. ╖ BBS data compressed to save space on disk, forwarding and downloading. ╖ "Live message capture" off BBS frequency, saves network traffic. ╖ PACSAT style bulletin broadcast transmitter and receiver. ╖ up to 200 simultaneous users. Where and How to obtain it. TNT by itself is available by anonymous ftp from: ftp.funet.fi <ftp://ftp.funet.fi/pub/ham/unix/packet/tntsrc09.tgz>.

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. Contributed by: Ron Atkinson, N8FOW, and Bdale Garbee, N3EUA 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. Freely distributable so long as the original copyright notice is not removed. Contributed by: Ron Atkinson, N8FOW 5.11.

RSPF Daemon Name RSPF - Radio Shortest Path First routing daemon for Linux Author Craig Small vk2xlz <csmall@triode.apana.org.au> Description An implementation of the Radio Shortest path First routing protocol for linux. The daemon supports version 2.2 of the protocol which corrects a lot of bugs and problems that were present in version 2.1. Status Alpha - running, needs testing and bug reports. Current version is 0.05 System requirements. Requires Alan Cox's kernel based AX.25 code. Detail This program will allow Linux to become an RSPF router. It addresses some of the quirks of RSPF v2.1, the version in NOS which means that it is incompatible with the NOS version. It will also allows remote/local queries via a tcp session for debugging and diagnostic purposes. Where and How to obtain it. Current versions are always available from sunsite.unc.edu <ftp://sunsite.unc.edu/pub/Linux/apps/ham/> or ftp.ucsd.edu <ftp://ftp.ucsd.edu/hamradio/packet/tcpip/incoming> or from the author.

Author Michael Westfall, N6KUY, <mwestfal@.csci.csusb.edu> Description A split screen terminal program that listens on the ttylink port and accepts incoming connection requests. Status Seems to work fine. System requirements none special. Detail This is a standalone program that does require you to change the configuration of your system at all. If you have root access on your machine then you run the program in a VT or in an XTerm and it will clear the screen and wait for an incoming connection on port 87 (ttylink). When a connection is received it will provide you with a split screen display with which to communicate with the calling person. Where and How to obtain it. You can obtain ttylinkd from: sunsite.unc.edu <ftp://sunsite.unc.edu/pub/Linux/apps/ham/ttylinkd.tgz> or ftp.ucsd.edu <ftp://ftp.ucsd.edu/hamradio/packet/tcpip/incoming/ttylinkd.tgz>. Licensing/Copyright Unknown, presumed freely distributable. 5.14. Craig Small's TTYLINK Daemon Name ttylinkd - a ttylink daemon for Linux. Author Craig Small, VK2XLZ, <csmall@triode.apana.org.au> Description A daemon to accept a ttylink (port 87) tcp/ip connection and convert it into a talk request for a user on the host machine. This may also be configured for use with the ax25d program so that AX.25 users may also make use of it to connect to you. Status Alpha, but working. System requirements. Kernel networking support with AX.25 support if desired. Detail Because the talk protocol is a non-standard, that is it isn't actually defined anywhere (except the source), the ttylink protocol from NOS has become the defacto standard, at least for amateurs, to provide keyboard to keyboard communication over tcp/ip. This daemon fills the need for something to answer ttylink requests to linux machines. To build and install the software, I did: # cd /usr/src # tar xvfz ttylinkd-0.02.tar.gz # cd ttylinkd-0.02 <edited the Makefile to change the SYSOP_USER> # make # cp ttylink /usr/sbin <edited /etc/service, /etc/inetd.conf as instructed in README> # killall -1 inetd Where and How to obtain it. You can obtain the latest version of ttylinkd from: sunsite.unc.edu <ftp://sunsite.unc.edu/pub/Linux/apps/ham/> or ftp.ucsd.edu <ftp://ftp.ucsd.edu/hamradio/packet/tcpip/incoming>.

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 <ftp://sunsite.unc.edu/pub/Linux/apps/ham/GW4PTS.morse.tar.gz>.

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. Licensing/Copyright Public Domain and may be freely copied as long as the notices at the top of sunclock.c remain intact. 13.3.

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 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: <terry@perf.no.itg.telecom.com.au> I'd list a packet radio address too but I'm still not properly operational again yet after moving house. 15. 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 vger.rutgers.edu. Other places where they are held include the tcp-group mailing list at ucsd.edu (the home of amateur radio tcp/ip discussions), and you might also try the #linpeople channel on the undernet irc network. To join the Linux linux-hams channel on the mail list server, send mail to: Majordomo@vger.rutgers.edu with the line: subscribe linux-hams in the message body. The subject line is ignored. To join the tcp-group send mail to: listserver@ucsd.edu with the line: subscribe tcp-group in the body of the text. Note: Please remember that the tcp-group is primarily for discussion of the use of advanced protocols, of which tcp/ip is one, in Amateur Radio. Linux specific questions should not ordinarily go there. 16. Copyright. The HAM-HOWTO, an introduction to Amateur Radio software available for Linux and information on how to configure some of it.
