DStar Repeater Controller UDP Sniffer (latest release v1.1)

This project tries to send every position received in a dstar repeater to aprs-is.

ICOM rpt sends all the traffic to the gateway using UDP port 20000. We try to capture that traffic sniffing the network while we unserialize the udp packets to get the slow speed data and routing information found in every DV transmission.

At the moment only kenwood /D74 received positions are sent to APRS-IS.

Install

In order to install Dstar sniffer you could:

wget https://github.com/elielsardanons/dstar_sniffer/files/1081265/DStarSniffer-1.1.tar.gz
tar xvzf DStarSniffer-1.1.tar.gz
cd DStarSniffer-1.1/
python setup.py install

Configuration

All the application configuration is in one file (/etc/dstar_sniffer/dstar_sniffer.conf):

[controller]
port= <where the icom rpt controller sends all the DV traffic>
iface= <name of the interface where the icom rpt controller is connected to the gateway>
ip= <ip of the icom rpt controller>

Dstar Sniffer will log all its output to /var/log/dstar_sniffer.log If you want to modify this you need to edit the file /etc/dstar_sniffer/logging.conf.
