1. To configure an SSH connection based on public key authentication instead of password authentication, just send your public key to the other party. If the public key is ~/.ssh/id_rsa.pub and the other party is [email protected], the command is ____________________________________;
2. If the public key is ~/.ssh/id_ed25519.pub and the other party is [email protected], the command is ____________________________________;
3. If the public key is ~/.ssh/id_ecdsa.pub and the other party is [email protected], the command is _____________________________________;
4. If the public and private keys are encrypted, do I need to enter the password when sending the public key to the other party? __________________. If the other party is [email protected], can I log in directly without entering a password by directly ssh [email protected] after sending the public key to the other party? ______________________________
5. If the public and private keys are encrypted, do I need to enter the password when sending the public key to the other party? __________________. If the other party is [email protected], can I log in directly without entering a password by directly ssh [email protected] after sending the public key to the other party? ______________________________
6. If the public and private keys are encrypted, do I need to enter the password when sending the public key to the other party? __________________. If the other party is [email protected], can I log in directly without entering a password by directly ssh [email protected] after sending the public key to the other party? ______________________________
7. For the encrypted public and private key pair, if you want to log in directly without entering the public and private key passwords the next time you ssh [email protected], what should you do? ___________________________________________
8. For the encrypted public and private key pair, if you want to log in directly without entering the public and private key passwords the next time you ssh [email protected], what should you do? ___________________________________________
9. For the encrypted public and private key pair, if you want to log in directly without entering the public and private key passwords the next time you ssh [email protected], what should you do? ___________________________________________
10. If there is an error with SSH, the next step is to check at which step the error occurred. If you want to check the process of ssh [email protected], what three options can help you? _________________________________________________________________________________________________________
11. If there is an error with SSH, the next step is to check at which step the error occurred. If you want to check the process of ssh [email protected], what three options can help you? _________________________________________________________________________________________________________
12. If an error occurs in SSH, the next step is to check at which step the error occurs. If you want to check the process of ssh [email protected], what three options can help you? _________________________________________________________________________________________________________

1. ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
2. ssh-copy-id -i ~/.ssh/id_ed25519.pub [email protected]
3. ssh-copy-id -i ~/.ssh/id_ecdsa.pub [email protected]
4. When using the ssh-copy-id command to send the public key to the other party, the password for the public and private keys is not required. No, although you do not need to enter the password for [email protected], you still need to enter the password for the encrypted public and private keys.

7. First, eval `ssh-agent` starts a ssh-agent process that keeps the private key. Then ssh-add ~/.ssh/id_rsa, enter the password of the public and private key pair, and let ssh-agent keep the private key. In this way, the next time you ssh [email protected], you can log in directly without entering the password of the public and private keys.
