Starting new: node doesn't start/sync

A friend asked me to help him get a stake pool setup so I’ve been investigating for a couple of weeks. Cardano stake pooling seems pretty interesting and something I’d like to work on getting up and running. I have some linux experience, but brand new to Cardano and the crypto environment.

I’m running ubuntu 20.04 and using the cardano-foundation videos/guild, coincashew, and guild operators documentation.

I’ve been able to work through getting prereqs installed and building the node. Have NOT been able to get it to start up correctly.

When I get to startup I run this:
cardano-node run
–topology testnet-topology.json
–database-path db
–socket-path db/node.socket
–host-addr 0.0.0.0
–port 3001
–config testnet-config.json

And get output like this:

If I use my public IP in the startup command it simple fails to start at all and goes back to the CL.

InvalidYaml (Just (YamlException “Yaml file not found: testnet-config.json”))

cardano-node: YAML exception:
Yaml file not found: testnet-config.jsonrelay@relay-CNODE:~/git/cardano-node/scripts$

It seems like a configuration or port issue to me. I’d like to get much more comfortable with the process on testnet and really play with it, but have hit a wall here. Any help or advice would be appreciated.

Thanks

Hi!

So far so good…
can you check that relays-new.cardano-testnet.iohkdev.io:3001 is reachable from your node?
netcat -znv relays-new.cardano-testnet.iohkdev.io 3001

I get this,

relay@relay-CNODE:~$ netcat -znv relays-new.cardano-testnet.iohkdev.io 3001
netcat: getaddrinfo for host “relays-new.cardano-testnet.iohkdev.io” port 3001: Name or service not known

So doesn’t look like I’m getting out. I disabled ufw while troubleshooting so that should not be contributing to the problem. Are there specific NAT considerations I should look at?

sorry, I thought that hostname can be used with the command, but only IP addresses.
so try to get the IP with ping relays-new.cardano-testnet.iohkdev.io then use the IP

$ netcat -znv 3.128.220.55 3001
Connection to 3.128.220.55 3001 port [tcp/*] succeeded!

relay@relay-CNODE:~$ netcat -znv 3.128.220.55 3001
netcat: connect to 3.128.220.55 port 3001 (tcp) failed: Connection timed out

I’m now getting timed out. Progress of sorts. This looks to me like a port issue. I can run the command from my local terminal and get this, netcat -znv 3.128.220.55 3001
3.128.220.55 3001 (redwood-broker) open.

Thanks for the direction, laplasz!!! I’ll work on the network and maybe rebuild locally to test and eliminate variables. I have linux experience, but it’s never been my strength. It’s been fun digging into all this.

it seems a routing issue… instead of a port issue.
yes, best way to learn these kind of things…

also you can try other addresses by visiting this site - the list contains other relays on testnet
https://explorer.cardano-testnet.iohkdev.io/relays/topology.json

Update here. The problem above did appear to be a routing issue. I changed networks and was able to startup and run. Received a lot of chain extended, new tip notifications. So I left it running, went to lunch and came back to it errored out. And now it won’t start and run correctly. I get these messages now.

Nothing changed from when I started up this morning to later in the day failing. Anything jump out to the experts to check? I’m doing this all on testnet.

try to add other relays to the topology.json from this list:
https://explorer.cardano-testnet.iohkdev.io/relays/topology.json
If not help then I would delete the database folder and start sync again.

While adding the additional relays to the topology file, I received messages that the formatting was incorrect. Deleted and re-downloaded the testnet topo file, started right up. Didn’t have to delete db folder or anything else.

Seems to be online and working now,

yes - so you just basically restarted the node… this can do the trick sometimes…:slight_smile:
