Article Title: Configure SSH verification for the UbuntuLinux system. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open-source, and other basic categories first generate public keys on the local machine

Ssh-keygen

Generate by default. If everything is normal, two files should be generated:

Id_rsa

Id_rsa.pub

One is the private key and the other is the public key. The public key file id_rsa.pub is copied to the server and then imported to the user who needs to log on.

For example, if you use the root user to log on to the ssh server, you can import the/root/. ssh directory.

Cat id_rsa.pub> authorized_keys

In this way, you can log on to ssh without entering the password.

Ssh root @ ssh-server
