Ethereum: Bitcoin Cli fails with an authorization error
As a programmer working with Blockchain Ethereum, it is necessary to understand how to interact with the network using commands tools such as “bitcoin-cli”. Recently, however, I encountered a problem in which “Bitcoin-Cli” did not know with an error of authentication. In this article, we will examine the problem and present steps to solve it.
problem:
When starting “Bitcoin-CLI”, the following output data is generated without any arguments:
`
Use: Bitcoin-cli [Options]
Or
Bitcoin-
Bitcoin Cli version 1.2.3
Error: Authentication error for the user’s “username”: not found.
`
An error message indicates that “Bitcoin-clliis unable to find an account of a specified user name.
Solution:
To solve this problem, you need to determine the correct username and password using the "-user" and "-pass" options. Here is the corrected command:
Bash
Bitcoind -DeDir =/Users/Varunvb/Downloads -Conf =/Users/Varunvb/Downloads/Bitcoin.conf -Deemon -USER "User name" -pass "Password"
Explanation:
- “-Ser” option determines the username for authentication.
- “-Pass” option determines the password for the user.
- You should replace “” username “and” password “with my actual I certify the Ethereum accounts.
Sample use of:
Let’s assume, for example, that you want to move ETH from one wallet to another. You will start the following command:
`Bash
Bitcoind -Datadir =/Users/Varunvb/Downloads -Conf =/Users/Varunvb/Downloads/Bitcoin.conf -Deemon -Ser "Myusername" -pass "MyPassword"
This will be authenticated with the Ethereum wallet and will allow you to move ETH between wallets.
Tips and variants:
- If you use another username or password, make sure you update the “Bitcoin.conf
file accordingly.
- You can also define many users by separating them by commas in the "-user" option. For example:
Bash
Bitcoind -DeDir =/Users/Varunvb/Download -conf =/Users/Varunvb/Downloads/Bitcoin.conf -Deemon -Ser 'User name1, User name2'
By following these steps and guidelines, you should be able to solve the authentication error using “Bitcoin-Cli` when starting it as a demon.
