p2p-probe

Probe a libp2p-compatible node and report the Identify protocol information.

Example usage for a Polkadot node:

p2p-probe /ip4/127.0.0.1/tcp/30333/ws  # for a full node
p2p-probe /ip4/127.0.0.1/tcp/30333     # for a validator

Docker

Example usage:

docker build . -t p2p-probe 
docker run p2p-probe /dns/polkadot-bootnode-0.polkadot.io/tcp/30333

Example output

$ p2p-probe /dns/polkadot-bootnode-0.polkadot.io/tcp/30333
