Block Producing/Relay Node Issues

Staking & Delegation Operate a Stake Pool
1

Hey guys,

I’m following the guide on setting up a stake pool and I’m at the part where you create your BP node and connect it to your relay node. This part has me a bit confused and I have a few questions/having some problems.

Do I need 2 different machines to run the BP node and the relay node? Everywhere that I read makes it seem like you only need 1 machine. So do you need 2 machines, 1 running the BP node and the other running the relay?

If you CAN run both on 1 machine, I’m having a problem. My BP node won’t connect to my relay. Here are my topology files:

Relay Node:

{
“Producers”: [
{
“addr”: “MY PUBLIC IP”,
“port”: 3002,
“valency”: 1
},
{
“addr”: “relays-new.cardano-testnet.iohkdev.io”,
“port”: 3001,
“valency”: 1
},
{
“addr”: “135.181.40.207”,
“port”: 3001,
“valency”: 1
},
{
“addr”: “95.179.151.144”,
“port”: 3001,
“valency”: 1
},
{
“addr”: “209.126.12.60”,
“port”: 3010,
“valency”: 1
},
{
“addr”: “3.21.223.154”,
“port”: 3001,
“valency”: 1
},
{
“addr”: “195.154.69.26”,
“port”: 3003,
“valency”: 1
},
{
“addr”: “104.131.99.185”,
“port”: 3000,
“valency”: 1
},
{
“addr”: “80.240.21.155”,
“port”: 3000,
“valency”: 1
},
{
“addr”: “35.203.149.28”,
“port”: 6000,
“valency”: 1
},
{
“addr”: “relays.cardano-testnet.uniquestaking.com”,
“port”: 3001,
“valency”: 1
},
{
“addr”: “76.169.10.127”,
“port”: 21983,
“valency”: 1
}
]
}

BP Node:

{
“Producers”: [
{
“addr”: “MY PUBLIC IP (Same as relay node IP)”,
“port”: 3000,
“valency”: 1
}
]
}

commands I’m using to start up each node:

Relay Node:

cardano-node run
–topology testnet-topology.json
–database-path db
–socket-path db/node.socket
–port 3000
–config testnet-config.json

BP Node:

cardano-node run
–topology testnet-topology.json
–database-path db
–socket-path db/node.socket
–port 3002
–config testnet-config.json

PS: I’m attempting to do this on a Raspberry Pi. If I do need two systems should I do 1 AWS instance as well as my Raspberry Pi? Also, I’ve already port forwarded ports 3000-3002. Does anyone have any ideas? Thanks!

You CAN run both on one machine, but you SHOULDN’T. Idea is to isolate BP node and not allow traffic to a BP machine so it can’t be DDOSed or easily attacked. This is also why you should have multiple relays so if one goes down you can still make blocks.

Got it, so what am I doing wrong? Why won’t my BP node find the relay? I want to walk through the tutorial on the testnet before setting up AWS instances when I’m ready to do it on the mainnet.

I would check your ports are actually open to the world using a port checker tool like https://www.portcheckers.com/ or ‘telnet ip port’ on the command line.

(Will only be open when the software is running)

hi,

if you have both nodes on 1 server, then put your local ip address in topology file, as well start the nodes with --host-address 0.0.0.0
