You can try:
1. visit the https://www.myetherwallet.com/#view-wallet-info
enter image description here 2. select the "Keystore / JSON File"
3. click the "SELECT WALLET FILE" and select the UTC--2018-09-08T03-31-16xxx-xxx file whic is located in your keystore folder.
4. If there is a "password" in your file, you will see a message "Your wallet is encrypted. Good! Please enter the password."
5. then, click the "Unlock" button
6. You may need to wait more than 10-30 seconds to be redirected to the next page and at the next page, you can get your private key
7. Open your metamask chrome extension
8. Change to the network
9. select "Import Account"
10. You can see a dropdown menu with "Private Key" or "JSON file"
enter image description here 11. Select "Private key"
12. Input your private key and it will create the same account address in metamask

Copying the private key only (field ciphertext of the UTC file) will give two different public addresses (one in geth and another in metamask). To solve this problem import de UTC file (present in the node keystore folder) directly in metamask.

When importing a file in metamask, make sure that you have the extension (metamask) running in it's own tab, otherwise it will not import anything.

Opening the extension in a tab (select Expand View in the ... menu): enter image description here

  • This worked for me. The key point was "make sure that you have the extension (metamask) running in it's own tab, otherwise it will not import anything."

  1. Create your account $geth account new
  2. Remember the password you used.
  3. Your private key will be in ~/.ethereum/keystore or ~/.ethereum/keystore/rinkeby
  4. Open metamask, select the network and then select "Import Account"
  5. Select Type "JSON File" (not "Private Key")
  6. Go to ~/.ethereum/keystore and select the private key (UTC-...)
  7. Enter your password from where you created the account.
  8. Voila! There's your new account.
