To listen for UDP multicast packets, the standard nc (netcat) utility is usually insufficient on its own because it lacks native IGMP join support. You must use socat or an updated netcat variant like ncat (from Nmap) to successfully join the multicast group and see the traffic.Here are the exact commands to accomplish this, ordered by reliability.

socat

This is the most reliable tool for multicast because it explicitly handles the IGMP group join request and can display the source IP address.

socat -v UDP4-RECVFROM:9131,ip-add-membership=239.255.250.250:0.0.0.0,fork -

You can use this by importing the function into the console (or your app)

> x = rateLimit(a, {rps: 1, grace: 2}); a = x[1]; x
[ true, 1635358774575 ]
> x = rateLimit(a, {rps: 1, grace: 2}); a = x[1]; x
[ false, 1635358774575 ]
> x = rateLimit(a, {rps: 1, grace: 2}); a = x[1]; x
[ false, 1635358774575 ]
> x = rateLimit(a, {rps: 1, grace: 2}); a = x[1]; x

let reqCount = 0;
// sample script
addEventListener("fetch", event => {
  event.respondWith(handleRequest(event.request));
});

async function handleRequest(request) {
  reqCount += 1;
  const headers = new Headers();
  //Set the proper content-type so the browser understands what we're sending back

First, run a new isolated container:

docker run --rm -it ubuntu bash

Now, setup npm and try to install package:

apt-get update && apt-get install -y npm
npm install grunt

You might see some funky garbage in your terminal window. Sometimes, it will hang, so expect to kill your session out of band.

## I’m thinking of a ten-digit integer whose digits are all distinct. It happens that the
## number formed by the first n of them is divisible by n for each n from 1 to 10.
## What is my number?
