Configuring an SSH Connection Using a Key
Configuring an SSH connection using a key is a secure way to connect to a remote system. It allows you to connect to the remote system without having to enter a password, making it more convenient and secure.
Here's how to configure an SSH connection using a key:
- Generate a key pair on the client system:
ssh-keygen -t rsa
This will generate a public key and a private key. The public key will be stored in a file named id_rsa.pub, and the private key will be stored in a file named id_rsa. Keep the private key secure, as it is used to authenticate the client system.
- Copy the public key to the remote system:
ssh-copy-id user@remote-system
This will copy the public key to the remote system and add it to the authorized_keys file in the .ssh directory of the user's home directory on the remote system.
- Test the connection:
ssh user@remote-system
If the connection is successful, you should be logged in to the remote system without having to enter a password.
That's all there is to it! You should now be able to connect to the remote system using an SSH key for authentication.
