Then restart ssh service to apply changes.
#Plesk keygen password#
To do so, you just need to edit the file /etc/ssh/sshd_config and to make sure the following settings are set : # disable root password authentication If you managed to login successfully on your server using ssh-keys, disabling password authentication is a good way to harden security on your server. You should now be able to login on your server with the command : ssh password authentication You can add it using echo like in the following example : echo 'ssh-ed25519 AAAAC3FzaC1lZDI1NTE5GGGAIEwb9hr5bNmB/+3oLJgixkj29l5rzKsfs5C+BlqTnPes > $HOME/.ssh/authorized_keys The public key is now located in /root/.ssh/idrsa.pub The private key (identification) is now located in /root/.ssh/idrsa file. Create the RSA Key Pair: ssh-keygen -t rsa -b 2048 Use default location /root/.ssh/idrsa and setup passphrase if required.

ssh in your user home directory if it doesn’t exist yet with mkdir $HOME/.ssh before adding your public key. How to set up SSH keys for Plesk server Answer Connect to the server via SSH. It should display something like that : ssh-ed25519 AAAAC3FzaC1lZDI1NTE5GGGAIEwb9hr5bNmB/+3oLJgixkj29l5rzKsfs5C+BlqTnPes new-vps, create the folder. To display the public key, you can use the command : cat. Otherwise, you just have to copy the first server public key and to add it in the file.
#Plesk keygen install#
If password authentification is allowed on your second server, you can use the command ssh-copy-id to automatically install your ssh public key from the first server : ssh-copy-id your ssh public key manually Install your public key on a remote server You can keep the default path for keys storage but it’s recommended to set a password to secure your private key because without password, anybody with your private key will be able to login on your server without password. You will be prompt for the path to store the keys and for a password. To generate ED25519 ssh keys, you can use the command : ssh-keygen -t ed25519 By default the command ssh-keygen will generate an RSA 2048 bits private-key, but you can also generate ECDSA or ED25519 ssh keys which provide a better encryption, with shorter public keys using the Elliptic curves algorithm.
To generate ssh keys, we will use the openssh built-in tool ssh-keygen. The public key need to be added on the remote server, and when you will launch your ssh connection, it will check if the public and the private key match, if not, you will be prompt for a password or disconnected if password authentification isn’t allowed. We talk about “SSH Keys” because it’s a matching pair of cryptographic keys (public and private). It’s also a way to make SSH connections easier, and it provide the ability to give an SSH access to somebody without having to share a password. Plesk Key Administrator 22.58.7 Operations Support System. With SSH Keys, SSH (Secure Shell) provide a more secured solution to login on your server than password authentification, because SSH keys are almost impossible to crack with brute-force attacks (consists to try each possible password). Partner Central is a new user interface for buying, tracking and managing Plesk licenses.
