To: ham-digital@ucsd.edu Hi, How are you? My name is Satoshi. I'm student from Japan. I'm studying English and American culture. I used to be an amateur packetter in Japan, and my call is JQ1TIV. If somebody interest, please send me an E-mail and talk about amateur radio.

I just ran across a program on Compuserve that is not-so-humbly billed as the best packet program ever. It is called "PAKET" and it is very, very good. Since it is shareware, give it a look. ************************************************************************ * Grover Cleveland WT6P@KE6LW.#NOCAL.CA * * Instructional Designer v(916) 478-3153 * * The Grass Valley Group Inc. - A Tektronix Company f(916) 478-3831 * * Grass Valley, California DoD 7388 * ************************************************************************ ------------------------------ Date: 26 Apr 94 20:18:01 GMT From: ihnp4.ucsd.edu!swrinde!gatech!udel!news2.sprintlink.net!news.sprintlink.net!connected.com!beauty!rwing!eskimo!rdonnell@network.ucsd.edu Subject: Linux and TCP/IP packet To: ham-digital@ucsd.edu Thomas Grant Edwards (tedwards@eng.umd.edu) wrote: : What is the best way for a Linux system already on the internet via : a ethernet Lan to also be on AX.25 TCP/IP via a TNC hooked into a : serial port? : Do I want Jnos or the GW4PTS AX.25 Package? : -Thomas : N3HAU I'd say it depends a lot on whether you make the service public or not. When you use the AX25 drivers in the kernel, as I understand it, you have no ability to set controls on what services or ip addresses pass from one port to the other. JNOS implements TCP and IP access controls. I've not tinkered with area yet, as my linux box is on a local ethernet with a jnos box handling the radios. However, for license preservation, look carefully at how much control you may need to exercise over non-amateurs attempting to use services or access stations on the air. The FCC is not in favor of unlicensed operations! 73 Bob, KD7NM ------------------------------ Date: 28 Apr 94 08:48:15 GMT From: dog.ee.lbl.gov!agate!howland.reston.ans.net!pipex!lyra.csx.cam.ac.uk!jhl14@ucbvax.berkeley.edu Subject: Linux and TCP/IP packet To: ham-digital@ucsd.edu In article , Bob Donnell wrote: >: What is the best way for a Linux system already on the internet via >: a ethernet Lan to also be on AX.25 TCP/IP via a TNC hooked into a >: serial port? >[...] >I'd say it depends a lot on whether you make the service public or not.

I am building a small baycom modem for AX.25 packet on 2m and would like to use my Atari Portfolio with a serial interface to create my first and portable packet station. P.S. The Atari Portfolio uses a derived version of msdos 2 or 3.XX I would require a compiled version if possible.
