ssh your_username@server_addressBut you can remove the annoying by being asked typing password many times, using RSA keypairs, it is also more secured than using password.
1. Creating a key pairs on Workstation
ssh-keygen -t rsa - b 4096
Add passphrase is recommended
To read your public key
cat ~/.ssh/id_rsa.pub
2. Uploading public keys to the Server
SSH to the Server
ssh your_username@server_address
Create a file in .ssh/authorized_keys and paste the public key into
you can do it from Workstation with one command using
cat ~/.ssh/id_rsa.pub | ssh your_username@server_address 'cat >> .ssh/authorized_keys'
And change the permission
ssh your_username@server_address ‘chmod 700 .ssh; chmod 640 .ssh/authorized_keys’
From now we can ssh with being asked for password
ssh your_username@server_address
3. Turn off password authentication
On Server Machine
sudo vim /etc/ssh/sshd_config
Uncomment Passwordauthentication , change the value to No
And restart ssh
sudo systemctl restart ssh
