Ethereum Bitcoin-CLI Getinfo Error Code: -28 on OSX Sierra

Have you encountered issues with accessing the blockchain information of Ethereum using the Bitcoin-CLI command-line interface (CLI)? Specifically, you’re experiencing an error code of -28 when trying to retrieve information using bitcoin-cli getinfo on your Mac running macOS Sierra. In this article, we’ll delve into the possible causes and solutions for resolving this issue.

What does -28 mean?

The error code -28 is a standard return code in Unix-like systems, including OSX Sierra. It typically indicates an unexpected operation or an internal system error that cannot be resolved by the CLI.

The Bitcoin-CLI getinfo command:

Before exploring possible solutions, let’s briefly review what the getinfo command does:

• Returns information about a block, such as its hash, timestamp, size, and more.

• Lists available addresses (also known as “addresses” or “keys”) on the blockchain.

The issue with Bitcoin-CLI on OSX Sierra:

The -28 error code is specific to the getinfo command. When you run bitcoin-cli getinfo, it likely tries to retrieve information from a database that stores blockchain data, including addresses and other metadata. However, due to various reasons (e.g., configuration or system issues), the CLI may encounter an internal error, resulting in a -28 return code.

Possible solutions:

• Check your Bitcoin-CLI configuration: Ensure you’re running the latest version of Bitcoin-CLI on your Mac. You can update the CLI by running git clone && cd btccli && ./configure --with-database=/path/to/database and then re-run . /set. This should help resolve any issues related to the database.

• Restart your Bitcoin-CLI session: Sometimes, simply restarting the CLI can resolve connectivity issues or other problems that may be causing the -28 error code.

• Disable IPv6: If you’re experiencing issues with DNS resolution or connectivity, consider disabling IPv6 on your system. This is because the getinfo command relies on DNS resolution to obtain address information from the blockchain. Disabling IPv6 can help resolve this issue.

Additional troubleshooting steps:

If none of the above solutions work, try:

• Checking for conflicts with other Bitcoin-CLI commands: Ensure that there are no conflicting commands running in the background that may be interfering with the getinfo command.

• Verify your system’s network connectivity: Make sure you have a stable and reliable internet connection to access the blockchain information from outside your local machine.

Bottom line:

The -28 error code returned by Bitcoin-CLI on OSX Sierra due to an internal system issue is usually not a critical problem. By checking for issues with your configuration, restarting the CLI session, or disabling IPv6 (if applicable), you should be able to resolve this issue and access Ethereum blockchain information using bitcoin-cli getinfo.
