Ethereum: unable to read macaroon path (check the network setting!): admin.macaroon: no such file or directory on lncli getinfo

Ethereum LND connection problem: unable to read MACAROON path

As a user of the Ledger Network (LND) for Ethereum, you’re probably new to the intricacies of running your own Ethereum node. However, when connecting to a Bitcoin node in the network, problems arise due to unique requirements and nuances. In this article, we will look at the error message provided by LND in Testnet, in particular, regarding the macaroon path.

Explanation of the error message

The error message displayed by the LND CLI is as follows:

Ethereum: impossible to read macaroon path (check network settings!)
admin.macaroon: No such file or directory
lncli GetInfo

At first glance, this may appear to be a problem specific to Bitcoin node connections. However, upon closer inspection, it becomes clear that LND has a problem with reading the macaroon' path.

LND Configuration

Ethereum: unable to read macaroon path (check the network setting!): admin.macaroon: no such file or directory on lncli getinfo

Before we dive into the possible solutions, let's take a look at how LND is configured:

  • In the LND configuration file (~/.lnd/Lnd.toml) the following setting applies:

[networks]
testnet = true
[lnd.log.level] = info

Possible Solutions

Given this information, here are some possible solutions to fix the problem:

  • Check network settings: The network settings in LND or configuration file (~/.lnd/Lnd.toml) may be incorrect.
  • Update~/.lnd/Lnd.tomlto reflect the correct network settings for Testnet, including thetestnetparameter set totrue.

[networks]
testnet = true
[lnd.log.level] = info

  • Check the MACAROON path: the error message specifically mentions that there is no file named admin.macaroon. This means that the path may be incorrect or absent.
  • Create a new directory namedadminin your preferred location (~/lnd/admin/) and place the Ethereum wallet files (usually found in$LND_DATA/lnd/admin/mnemonic.jsonand/home/user/.ethereum/keys/) in this newly created directory.

mkdir ~/lnd/admin/
cd ~/lnd/admin/

  • Use lnd-cli with a different wallet path

    : Try using the LND CLI with an alternate wallet path.

  • Replace $LND_DATA/lnd/admin/ with /home/user/.ethereum/keys/ (assuming you have a key file named mnemonic.json).

lnd --wallet-path=/home/user/.ethereum/keys/mnemonic.json getinfo

  • Check wallet file access: Make sure the wallet files are readable by the LND process.
  • If you use a specific directory for your wallet files, make sure it is accessible to the LND process.

Conclusion

The Ethereum: unable to read macaroon path (check the network setting!)' error message often occurs due to incorrect or missing paths in the LND configuration file (~/.lnd/Lnd.toml) or a non-existentadmin.macaroondirectory. By checking these potential solutions, you will be able to solve the problem and successfully connect your Ethereum node to the Testnet.

Additional Tips

  • Keep your wallet files up to date by updating them regularly.
  • Make sure your LND process has write access to all directories containing your wallet files.
  • Consider creating a configuration file~/.lnd/Lnd.toml` with the correct settings for Testnet.
