RedHat v7.2 (2.4 Kernel) and Echolink!

RedHat v7.2 (2.4 Kernel) and Echolink!

[-- Attachment #1: Type: text/plain, Size: 769 bytes --]

Hello Everyone -

I finally got Echolink working on my LAN system (Windoze98).  I had to 
convert from
"ipchains" to "iptables".  After reviewing numerous "firewall scripts" 
and some help info
from Echolink I was able to piece it all together.  So using what I 
found along with some
additions of my own I have been successful.  Just in case there are 
others who might
contact the list regarding Echolink configuration issues, I am attaching 
my firewall
script to this message.  I am sure that allot of you could have 
accomplished the task
easier and better than I did.  However, mine works and that is good 
enough for me!

I have received some valuable help here on the list and this is just my 
way of trying
to contribute something in return.

Wx stations and aprs

[mvw]

Hello all,

Xmas was good in terms of spare time. I am still working on my active
home. I now have x10 installed and fbb running (basically: though it's
local; unless you log in via ax25 it still does not get/send mail or
bulletins from the outside world).

Anyway - two different questions this time.

a) APRS! Any recommendations for both Linux software and maps?

b) Weather stations - I would love broadcast my local Wx status on APRS,
but before I spend money unwisely, what weather stations (and associated
software) has worked for any of you?

Best,
Michael VA3MVW

You might be interested in what I am currently working on. It is in the beta
stages of development, but I believe you can get a good idea of what is to
come:

Hello Michael

Have a look on Erick F5EXO page at http://f5exo.free.fr
I convert his axmeteo software to a RPM at
http://f6fgz.free.fr/Fichiers/axmeteo-2.3.3-1.i386.rpm

It can broadcast weather infos as APRS beacon. Plus other nice features !

Xastir:


    www.xastir.org
or  xastir.sourceforge.net


Here's a description of the types of maps, tnc, and weather stations
that it supports:


    http://www.eskimo.com/~archer/xastir.html


Run the Jan 1, 2003, development version of Xastir, not the aged
"stable" version.

Xastir supports several different types, including network
connections from Xastir to weather daemon software.
