# This scripts should be sourced by the /etc/services.d/xxx/run modules for
|
|
# readsb, mlat-client, and mlathub. It interprets the ULTRAFEEDER_CONFIG / ULTRAFEEDER_NET_CONNECTOR parameter
|
|
# and makes individual net-connector strings available for these three modules.

|
|
# Note:
|
|
# ULTRAFEEDER_CONFIG and ULTRAFEEDER_NET_CONNECTOR can be used interchangeably
|
|
# If both are defined, they will be considered jointly.
|
|
#
|
|
# Format:
|
|
# ULTRAFEEDER_CONFIG=adsb,host,port,protocol[,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,extra-arguments]
|
|
# ULTRAFEEDER_CONFIG=mlat,host,port[,return_port][,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,extra-arguments]
|
|
# ULTRAFEEDER_CONFIG=mlathub,host,port,protocol[,uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX][,extra-arguments]
|
|
#
|
|
# The ULTRAFEEDER_CONFIG parameter can have multiple config strings, separated by a `;`
|
|
# Please note that the config strings cannot contain `;` or `,` -- undefined things may happen if these characters are present.
|
|
#
|
|
# In the above configuration strings:
|
|
# `host` is an IP address. Specify an IP/hostname/containername for incoming or outgoing connections.
|
|
# `port` is a TCP port number
|
|
# `protocol` can be one of the following:
|
|
# `beast_reduce_out`: Beast-format output with lower data throughput (saves bandwidth and CPU)
|
|
# `beast_reduce_plus_out`: Beast-format output with extra data (UUID). This is the preferred format when feeding the "new" aggregator services
|
|
# `beast_out`: Beast-format output
|
|
# `beast_in`: Beast-format input
|
|
# `raw_out`: Raw output
|
|
# `raw_in`: Raw input
|
|
# `sbs_out`: SBS-format output
|
|
# `vrs_out`: SBS-format output
|
|
# `uuid=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX` is an optional parameter that sets the UUID for this specific instance.
|
|
# It will override the global `UUID` parameter. This is only needed when you want to send different UUIDs to different aggregators.
|
|
# `input_connect=host:port is an optional parameter that sets the input_connect values for this instance`
|
|
# `lat=xxxx` is an optional parameter that sets the latitude for this specific instance
|
|
# `lon=xxxx` is an optional parameter that sets the longitude for this specific instance
|
|
# `alt=xxxx` is an optional parameter that sets the altitude for this specific instance
|
|
# `extra-arguments` can be any additional command line argument you want to pass to readsb, mlathub, or mlat-client
|
|
# Example: `--net-only`. Please make sure to only once pass in an extra argument for each of the adsb|mlat|mlathub service.
