Aprx is a software package designed to run on any POSIX platform (Linux/BSD/Unix/etc.) and act as an APRS Digipeater and/or Internet Gateway. Aprx is able to support most APRS infrastructure deployments, including single stand-alone digipeaters, receive-only Internet gateways, full RF-gateways for bi-directional routing of traffic, and multi-port digipeaters operating on multiple channels or with multiple directional transceivers.
Aprx was originally written by Matti Aarnio, who has not been able to continue being actively involved in its development and support. This site is the source of any future work built upon Matti's by Kenneth Finnegan.
The minimum configuration for a receive-only Internet gateway is as follows in /etc/aprx.conf:
mycall EXAMPL-1
<aprsis>
passcode 12345
server rotate.aprs.net 14580
</aprsis>
<interface>
serial-device /dev/ttyS0 9600 8n1 KISS
</interface>
To configure aprx as a stand-alone RF digipeater, add a digipeater block with the RF interface as the transmitter and the source.
mycall EXAMPL-2
<interface>
serial-device /dev/ttyS0 9600 8n1 KISS
tx-ok true
</interface>
<digipeater>
transmitter $mycall
<source>
source $mycall
</source>
</digipeater>
To configure a site as both an RF digipeater and an Internet gateway, add the APRSIS block from EXAMPL-1 to the beginning of the EXAMPL-2 config. See the aprx manual for instructions on how to create more sophisticated configurations.
