I am running the golang implementation of bitcoin and trying to query the JSON-RPC API remotely. I am trying with the example demonstrated here but I get an error saying the connection was refused.

I have configured rpcuser and rpcpass in both btcd.conf and btcctl.conf, I have also tried generating new key and cert with the gencerts command

Code:

gencerts -d /home/user/.certsforhosts/ -H 192.168.0.104

but I still get the same error.

What might be wrong with my configuration?

btcd.conf

Code:

datadir=/home/user/blockchain/

rpcuser=user1
rpcpass=pass1
rpclimituser=user2
rpclimitpass=pass2

txindex=1
addrindex=1

rpccert=/home/user/.certsforhosts/rpc.cert
rpckey=/home/user/.certsforhosts/rpc.key

btcctl.conf

Code:

rpcuser=user1
rpcpass=pass1
rpccert=/home/user/.certsforhosts/rpc.cert

my code

Code:

var fs = require('fs');
var WebSocket = require('ws');

var cert = fs.readFileSync('path/to/my/rpc.cert');
var user = "user1";
var password = "pass1";

var ws = new WebSocket('wss://192.168.0.102:8334/ws', {
  headers: {
    'Authorization': 'Basic '+Buffer.from(user+':'+password).toString('base64')
  },
  cert: cert,
  ca: [cert]
});

ws.on('open', function() {
    console.log('CONNECTED');

    ws.send('{"jsonrpc":"1.0","id":"0","method":"notifyblocks","params":[]}');
});
ws.on('message', function(data, flags) {
    console.log(data);
});
ws.on('error', function(derp) {
  console.log('ERROR:' + derp);
})
ws.on('close', function(data) {
  console.log('DISCONNECTED');
})

Code:

bitcoin-cli getconnectioncount

Gives me an amount of 86 connections, my node has been running for a couple of months with 100% uptime. educational purposes

Is this a high number of connections? How many does your node have?
I would also like to know if your node is visible on https://bitnodes.earn.com/ or not, mine shows up there around 9/10 times I check.

The same site also says:

The crawler maintained by Bitnodes connects from these IP addresses: 136.243.139.96, 136.243.139.120, 2a01:4f8:212:3b1f::2

Are these IP addresses usable with the

Code:

-addnode=<ip>

configuration?

Greetings!

I just started running a full node on raspberry pi 3 in order to help the network.
Everything seems to be working just fine but the problem is that my node version is 0.13.x

When I installed my node I followed this guide https://bitcoin.org/en/full-node#linux-instructions

Code:

sudo apt-get install bitcoin-qt

This command installed the dated version. Is it possible to get the latest version 0.15.1 with GUI for raspberry pi? If so, how?

Is it useless to run a node with dated version?

I have downloaded the ARM Linux 32-bit and it did not come with a bitcoin-qt.

Thank you.
