Common Issues

  • Permission denied errors when starting the client: Ensure that the client.conf file has the correct file permissions and is owned by the user running the client.
  • RPC connection refused errors: Check that the rpcuser and rpcpassword settings are correct and that the RPC port is open for connections.
  • Client not syncing: Verify that the connect and addnode settings are correct, and that the client has a stable internet connection.

Integration

The client.conf file can be used in conjunction with other commands and tools to manage Bitcoin and Litecoin nodes:

  • bitcoind -conf=client.conf: Start Bitcoin Core with the specified configuration file.
  • litecoind -conf=client.conf: Start Litecoin Core with the specified configuration file.
  • bitcoin-cli -conf=client.conf: Interact with the Bitcoin Core client using the command line interface.
  • litecoin-cli -conf=client.conf: Interact with the Litecoin Core client using the command line interface.
