To use the key pair for SSH authentication, you’ll need to copy the public key to a server. To use default settings, hit Enter on the prompts for file location and passphrase. On the host machine’s terminal, use this command to create a key pair: ssh-keygen -t rsa When you create an SSH key pair, there is no longer a need to enter a password to access a server. SSH key pairs are used to authenticate clients to servers automatically. The public key can be shared, while the private key needs to stay secure. The pair consists of a public and private key. To improve the security of SSH connections, generate a key pair with the keygen utility. For example: ssh -p 3322 Generate SSH Keys Using SSH Keygen If you are able to connect and the Jelastic Shell shows you a list of the environments in your account, you have successfully added your public key to your account! You can find out more about the SSH Gate in our Using the SSH Gate guide.To connect to a remote host with a custom SSH port number, use the -pflag. Paste that command into your terminal and hit enter to connect to the SSH Gate! The first time you use the SSH Gate, you will need to type “yes” to confirm the connection. Go to the SSH Connection tab, then copy the command under the SSH Gate section. Once the key has been added, we can test it out by connecting to the SSH Gate. You can give the key a name, then paste your public key in the Key field. Next, log in to your Reclaim Cloud Dashboard at app.my.reclaim.cloud and click the Settings button at the top right. To use this feature, you must add your public key to your Reclaim Cloud account.įirst, follow the directions in the Viewing and copying your public key section, so you have the key copied to your clipboard. Reclaim Cloud has an SSH/SFTP Gate which is a huge time saver because it allows you to access every node in your account even if they do not have a public IP or SSH and user accounts configured. This will output the key to your terminal, you can then select the text starting with “ssh-ed25519” and ending with your computer’s name, and copy that text to your clipboard.Īdding your public key to your Reclaim Cloud account To do this, from a terminal run the following command: cat ~/.ssh/id_ed25519.pub If you happen to be installing a public key on a server manually, need to use it with Reclaim Cloud’s SSH Gate, or need to share it with us at Reclaim, you may have to copy the key to your clipboard. Once that process is complete, try logging in via ssh: ssh you log in to the server and are not prompted for a password, the key has been installed! Then, you will be asked to enter your password for the server. The ssh-copy-id command works similarly to the ssh command: ssh-copy-id will be prompted if you would like to continue connecting, so type "yes" and hit enter. If you are looking for more info on connecting to a cPanel account via SSH, check out our Connecting via SSH article. In this example, we’ll use it to add a key to a cPanel account, so you'll need to know your cPanel username and password. Installing your public key on a server with ssh-copy-idĪ quick way to install a public key on a server is to use the ssh-copy-id command. The id_ed25519 file is your private key and should never be copied to a server or shared with anyone, and id_ed25519.pub is your public key that can be installed on a server. You should be able to see an id_ed25519 and id_ed25519.pub file. ssh directory to see both the public and private keys. This key type is now deprecated, and in some cases is no longer supported by default in some recent OS releases (MacOS Ventura in particular).Īfter the key pair has been generated, we can use ls in the. It is worth mentioning that specifying the type of key with the -t flag is important, as by default, ssh-keygen will generate keys of the RSA type. It will also ask for a password, which you can also leave empty. The command will ask for a filename, which you can leave empty if this is your first ssh key pair you're generating on your computer. In a terminal, enter: ssh-keygen -t ed25519 There are other ways to generate public and private keys using programs like PuTTY on Windows, but that is out of scope for this guide. On Windows, you can follow these directions if you first set up OpenSSH for Windows or install Linux via WSL. On macOS and Linux, we can use the ssh-keygen command to get started. SSH keys allow you to log in to a server without having to type a password and are generally preferred over passwords for security reasons (they are not guessable, and it's more difficult to unintentionally share them). This key pair can be used as an alternative to passwords when connecting via SSH or SFTP. An SSH key pair consists of a private key, which is a text file that stays on your computer, and a public key, which is an accompanying text file that can be installed on a server.
