First time starting a node, DiffusionErrored

Developers Misc Dev Talk

Hi and sorry to bother you but I have got a bit stuck and hope you can give me some pointers.

I have been following along the documents to start a node and everything has gone well so far but starting the node I get an error I can not overcome.

As you can see I get the error
DiffusionErrored Network.Socket.bind: unsupported operation (Cannot assign requested address)

For the topology file, I just went to https://explorer.mainnet.cardano.org/relays/topology.json to find some active producer nodes

{
  "Producers": [
    {
      "addr": "relay1-pub.ahlnet.nu",
      "port": 2111,
      "valency": 2
    }
  ]
}

For the start command i have:

cardano-node run
–topology testnet-topology.json
–database-path db
–socket-path db/node.socket
–host-addr 34.248.22.26
–port 3001
–config testnet-config.json

All ports are open.

I have not updated the testnet-config.json, testnet-shelley-genesis.json or testnet-byron-genesis.json from the ones provided.

This is the full stack trace.

Thanks

Shutting down..

Start the node with host-addr 0.0.0.0

Thank you, that did the trick.

FYI
I had the error in the same context.

[XXXXX:cardano.node.DiffusionInitializationTracer:Info:61] [2021-12-31 16:55:59.80 UTC] ConfiguringLocalSocket (LocalAddress “YYYYYY/cardano/db/node.socket”) (FileDescriptor 24)
[XXXXX:cardano.node.DiffusionInitializationTracer:Info:5] [2021-12-31 16:55:59.81 UTC] DiffusionErrored Network.Socket.bind: permission denied (Operation not permitted)

The reason was that the …/db directory was in a smb ressource. I find no solution to create a socket file on a smb (cifs) file system.

do not share the server’s user :beers:

You’re right

A bit ignorant here, but can you elaborate on what you mean by “do not share the server’s user”?
Sorry for the elementary question

8

For testnet is not an issue but for mainnet don’t share informations on public media such as servers username, BP IP, etc (infos which can be used by some one to hack ur nodes)

Cheers,

Oh that comment was as simple as that, sorry I was mistaking it for a solution rather than a best practice. Understood! I was having an issue with my node.socket file also being on the external HD and that obviously didn’t work until I put it back on my local drive. So I thought your comment was related. Thanks!
