Quickstart: replay a slot range

In about five minutes you will replay a recent slot range into a UDP receiver and watch its packet counter move.

Before you start

You need:

An access with ShredReplay enabled
A UDP receiver at a globally routable public IPv4 address, listening on a port from 1024 through 65535

The Raw Shred Stream receiver works unchanged; both products send raw shred datagrams.

Start the receiver

SHREDSTREAM_PORT='<udp-port>' node receiver.mjs

Leave it running. Open the port through the host firewall, security group, and any NAT forwarding rule.

Create the key and job

Generate a replay key

Open Endpoints → ShredReplay, select the access, and generate a ShredReplay key. Store it as a secret; it is separate from location tokens.

Choose a slot range

Enter start and end slots inside the minimum and maximum the panel shows. Refresh the range right before you submit; the window keeps moving.

Enter the receiver

Enter the receiver’s public IPv4 address and UDP port.

Choose pacing and start

Select Original pacing for a first run, keep Speed multiplier at 1, and start the job.

Watch the receiver:

Listening for ShredStream on UDP 20000
packets=0 bytes=0
packets=961 bytes=1184331

The job worked when the panel shows it completed and the receiver printed nonzero counts while it ran. Completion means the sender finished the range; UDP delivery is not acknowledged.
