ssh without password

1. Install SSH:$ sudo apt-get install SSH2. See if the catalog is generated. SSH:$ ls-al/home/ubuntu/3. If not, create the directory manually. SSH:$ mkdir/home/ubuntu/.ssh4. Generate public and private keys:$ ssh-keygen-t dsa-p '-f ~/.SSH/ID_DSA or $

In the following example, ssky-keygen and ssh-copy-id can be used to log on to a remote Linux host without a password. Ssh-keygen creates the public key and key. Ssh-copy-id copies the public key of the local host to the authorized_keys file of the remote host. The ssh-copy-

principle: Use the required user to log in to the client, use Ssh-keygen to generate the user host private key and key, and upload the client public key to the server-side fixed file. When the client accesses the server side via SSH, the server generates a random number and encrypts the random number with the client's public key and sends it to the client. After the client receives the encryption number in

Use ssh authentication in linux without entering a password to access another machine In work, ssh authentication is usually performed on each machine that logs on to another machine through ssh, so you do not need to enter a complicated password every time. The key to this
