After setting up a chain node on AWS EC2 instance with geth, I'm wondering if there is any additional configurations needed or which IP address should I use to connect to it? Currently, I am incorporating web3.js with the following code: new Web3.providers.WebsocketProvider('wss_address', abiOptions)
I have enabled websocket support by using --ws flag. This resulted in getting the message "WebSocket enabled url=ws://127.0.0.0.1:8546".
Information extracted from the Geth documentation page regarding command-line options:
--ws (default: false) ($GETH_WS)
Activation of the WS-RPC server
--ws.addr value (default: "localhost") ($GETH_WS_ADDR)
Interface on which the WS-RPC server listens
--ws.api value ($GETH_WS_API)
APIs offered through the WS-RPC interface
--ws.origins value ($GETH_WS_ORIGINS)
Specific origins allowed for websocket requests
--ws.port value (default: 8546) ($GETH_WS_PORT)
Port on which the WS-RPC server listens
--ws.rpcprefix value ($GETH_WS_RPCPREFIX)
Prefix path for serving JSON-RPC over HTTP. Use '/' to serve on all paths.
If only using the --ws option, the default value of --ws.addr is applied and the node will only accept requests from the local machine.
You can specify the network interface that the node should listen on by providing its IP address or hostname. For example, if your server's IP is 123.123.123.123, you can use the following IP. This setup allows the node to receive WS connections specifically to this IP.
geth --ws --ws.addr "123.123.123.123"
If you wish to listen for incoming requests from all network interfaces of the server (e.g., localhost, LAN cables, VPN tunnel, wifi, etc.), you can set the value of --ws.addr to 0.0.0.0. This configuration enables the node to accept all inbound WS connections.
geth --ws --ws.addr "0.0.0.0"
Executing the following command:
nohup ./geth --config ./config.toml --datadir ./node --cache 8500 --rpc.allow-unprotected-txs --txlookuplimit 0 --ws --ws.addr "0.0.0.0" --ws.origins "*" --ws.api "web3, eth" &
And using this line for connection:
new Web3.providers.WebsocketProvider('ws://yourPublicIpAddress:8546', abiOptions)
Everything is functioning correctly, gratitude for the assistance)))
P.S. In my scenario, specifying the PORT in the connection was crucial. Additionally, connecting via ws opposed to wss made the difference. Interestingly, there was no noticeable distinction when connecting via IP with or without DNS.
