![]() ![]() One more method is to use this command: sudo kill -HUP $(cat /var/run/sshd.pid) To implement the change we just made, we’ll need to restart the ssh service: $ sudo systemctl restart sshĪlternatively, we can use this command: sudo kill -HUP `cat /var/run/sshd.pid` Once in the file, let’s search for a line that reads “PasswordAuthentication”. It may be uncommented depending on our system, but we can enable it by removing the “#” sign at the beginning, then set its value to “no”: PasswordAuthentication noįinally, let’s save and close the file. This is important to ensure that we’ll still be able to gain administrative access.įirst, let’s log in to our remote server through SSH and then open the SSH configuration file through nano: $ sudo nano /etc/ssh/sshd_config We need to make sure that we have an SSH key authentication setup with the root user or any other available user with sudo privileges. It’s critical for us to disable password-based authentication that’s still active to protect our remote server against brute-force attacks. The key is copied to the ~/.ssh directory on the remote server, in a file name authorized_keys. When we enter the correct password, the utility will connect to the remote server and copy over our public key. Once it locates the key, it’ll prompt us to enter the password on the remote server. The utility will proceed to scan for the public key we generated earlier. Let’s type in yes, then hit ENTER to continue. Getting this message is normal because our local computer doesn’t yet recognize the remote server. The authenticity of host 'xxx.x.xxx.x (xxx.x.xxx.x)' can't be established.ĮCDSA key fingerprint is fd:fd:d4:f9:77:fe:73:84:e1:55:00:ad:d6:6d:22:fe.Īre you sure you want to continue connecting (yes/no)? It requires us to specify an IP address for the remote host, and the user account with password-based authentication enabled: $ ssh-copy-id _host_ip_address We must have password-based authentication enabled to use this method. It’s included in the OpenSSH packages in most Linux distributions, so we don’t need to install it. ![]() It’s the easiest and most recommended method for copying a public key. Ssh-copy-idis a utility to copy the public key to a remote SSH server. ![]() The next step is copying the public key to a remote server. We now have a public key and a private key we can use for authentication. SHA256:f6sdCUZLKUm61/Mbv7DZh+NNR4Dn7oA+vnb4JB82qyc Your public key has been saved in /home/user/.ssh/id_rsa.pub We get this output on successful key pair creation: Your identification has been saved in /home/user/.ssh/id_rsa We need to enter it every time we use the private key.Įntering a passphrase is optional, but recommended for a secure system. If you sign in through Google and haven't defined a password, you can set one on the Reset Password page.Next, we’ll be prompted to enter a passphrase to encrypt the private key on our local computer: Created directory '/home/user/.ssh'.Įnter passphrase (empty for no passphrase):Ī passphrase serves as an extra layer of security to secure the private key generated. Make site changes via SFTP or Git using your account password to authenticate. You can still access the sites if you have active sites and no keys remaining.

You can use your Dev environment to clone your site code to your workstation: Paste the copied public key into the Add Key box. Open the Account tab in your User Dashboard. You can view a list of available keys on the same page.Ĭlick your username in the top right, then select My Dashboard. Your computer is now set up to securely connect to the Pantheon Git server.
