Two different peer id, for single node.

[harsh-98]

I was going through the starting your own private network with https://www.substrate.io/tutorials/start-a-private-network/v2.0.0-rc2. I generated keys with subkey. Created chainspec, started node 1 and node2 . But node 2 failed with

Error: Service(Network(The same bootnode (`/ip4/127.0.0.1/tcp/30333`) is registered with two different peer ids: `QmYkKnqtB46sufgYSPUBCFUdYn8ipvZ1H8jSDzvpMjx6wp` and `QmYb6raWsGsw5rpncKW2iJUBTxP3SdFy8KzjofaEtBAiJy`))

Id QmYb6raWsGsw5rpncKW2iJUBTxP3SdFy8KzjofaEtBAiJy was printed in logs of node1. But using it as bootnode peer id for node2 failed. Using QmYkKnqtB46sufgYSPUBCFUdYn8ipvZ1H8jSDzvpMjx6wp worked and I was successfully able to complete it.

Why is node1 printing a peer id and using another peer one?

This is probably because your chain spec file contains one boot node address, but your bootnode itself advertises a different one. For this tutorial, there should not be any bootnodes in your chainspec file.

Please open your customSpecRaw.json file and look for a line like this near the top.

"bootNodes": [],

If that list contains an actual bootnode, please remove it, and try again.

If you followed the tutorial exactly you shouldn't end up in this situation because https://www.substrate.io/tutorials/start-a-private-network/v2.0.0-rc2/customspec#create-a-chain-specification says to generate your custom spec using this command.

# Export the local chainspec to json
$ ./target/release/node-template build-spec --disable-default-bootnode --chain local > customSpec.json

When you include --disable-default-bootnode as demonstrated, your spec file does not include that bootnode address.

Yup, thanks.

Hi, I do have similar issue with the following error:
error: Invalid value for '--bootnodes ...': invalid multiaddr

Can assist on this issue?

Thank you

Can you describe what are you doing when you encounter this error? Were you working with chain specs? If so, how did you generate them?
