AprsProxy

I was thinking how to monitor APRS statistic from my iGates (from me or friends), one proper way is to run a APRS proxy server between iGates and APRS-IS server. But I just could not find a software to do this so I decided to write my own.

This APRS proxy server would received packets from devices, logged it into files, generate statistic or send/forward specific aprs packets to other application, replace the text to meet my requirement and resend packets to native APRS-IS server.

Features

Text replacing with multiple keywords
Build-in forwarder
Simple, no config file with only one command
Handle multi client connections with highly efficiency
You can use aprs-is via domain name
Daily log to files
Work with docker

Command

``` bash $ ./aprsproxy -h _
/ _ | __ / _ _ _ _ _ / _ |/ _ \/ _(-/ / _ \ \ / // / // |/ .// /// // _/_\, / // /_/
A simply APRS-IS proxy tool.

OPTIONS: --to Forward the matched APRS packets to Send-only APRS-IS service with http protocol [default: china.aprs2.net:8080] --forward ... Forward APRS packets start with the line prefix -l, --local The local address and port to listen on [default: 0.0.0.0:14580] -r, --remote The remote address and port to connect to [default: china.aprs2.net:14580] --replace ... The text to be replaced, can be multiple values --with ... The text to replace with, must be the same length of replace-from ```
