Pre-compiled samplicator UDP replicator (https://github.com/sleinen/samplicator) on alpine linux.
Full Description

UDP Samplicator

This small program receives UDP datagrams on a given port, and resends
those datagrams to a specified set of receivers. In addition, a
sampling divisor N may be specified individually for each receiver,
which will then only receive one in N of the received packets.

USAGE

The usage convention for the program is

$ samplicate [<option>...] [<destination>...]

Where each <option> can be one of

-d <level>    to set the debugging level
-s <address>    to set interface address on which to listen
        for incoming packets (default any)
-p <port>    to set the UDP port on which to listen for
        incoming packets (default 2000)
-b <buflen>    size of receive buffer (default 65536)
-c <configfile>    specify a config file to read
-x <delay>    to specify a transmission delay after each packet,
        in units of    microseconds
-S        maintain (spoof) source addresses
-n        don't compute UDP checksum (only relevant with -S)
-f        fork program into background
-m <pidfile>    write the process ID to a file
-4        IPv4 only
-6        IPv6 only
-h        to print a usage message and exit

and each <destination> should be specified as
<addr>[/<port>[/<interval>[,ttl]]], where

<addr>        IP address of the receiver
<port>        port UDP number of the receiver (default 2000)
<freq>        number of received datagrams between successive
        copied datagrams for this receiver.
<ttl>        The TTL (IPv4) or hop-limit (IPv6) for
        outgoing datagrams.

Config file format:

a.b.c.d[/e.f.g.h]: receiver ...

where:

a.b.c.d     is the sender's IP address
e.f.g.h     is a mask to apply to the sender (default 255.255.255.255)
receiver    see above.

Receivers specified on the command line will get all packets, those
specified in the config-file will get only packets with a matching
source.
