How to upload an SSH key via the Cloud Control Panel

DreamCompute utilizes ssh keys for accessing your servers for increased security and simplified user management. On first boot, your public key is injected into the server for the default user. This enables passwordless logins and prevents unnecessary file modifications on startup.

SSH key pairs contain a private key and a public key. Hang on to your private key and keep it secret. The public key ends with a ”.pub” extension and will be injected into your server.

Existing SSH key

If you’re using Mac or Linux, you may already have SSH keys. If so, they are typically stored in the hidden .ssh directory.

[user@localhost]$ ls ~/.ssh/
/home/myuser/.ssh/id_rsa  /home/myuser/.ssh/id_rsa.pub

If you’re using Windows, there’s a good chance you’re using PuTTY. SSH keys generated on Windows systems using the generator (puttygen.exe) are not stored in a uniform location, but instead where the user chooses to save them.

Create a new SSH key

Windows via PuTTYgen

PuTTYgen is an SSH key generator program for Windows. It is included in the PuTTY MSI installer package that can be downloaded from the PuTTY website.

PuTTY

Start the program, click on the “generate” button, and follow the instructions displayed. When complete, click the “save private key” button to save the .ppk (PuTTY Private Key File) file for use with PuTTY later.

The text at the top labeled “Public key for pasting into OpenSSH authorized_keys file” can be copy/pasted into a text file for importing into the Cloud Control Panel and other future uses.

Note

The “save public key” button saves a modified version of the public key that won’t directly import into the Cloud Control Panel.

Mac and Linux via ssh-keygen

ssh-keygen is a command line key generator tool included on Mac, Linux and other unix-based operating systems. Run it in your terminal app.

[user@localhost]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/myuser/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/myuser/.ssh/id_rsa.
Your public key has been saved in /home/myuser/.ssh/id_rsa.pub.
The key fingerprint is:
66:d9:a4:f0:8d:0b:72:93:b8:67:2e:af:f6:91:ce:e3 myuser@mycomputer
The key's randomart image is:
+--[ RSA 2048]----+
|                 |
|                 |
|      .   .      |
|     . + B       |
|    o = S o      |
|     + * .       |
|    . = .        |
|    o*..         |
|   ..*E.         |

Note

Defaults are in parentheses. A password is recommended but not required.

Upload SSH public key

Click the LAUNCH A SERVER button in the Cloud Control Panel.

Click the IMPORT SSH PUBLIC KEY button

../../_images/import-ssh-sunrise.png

Give your SSH key a name and paste the contents of your SSH public key into the field. Click the IMPORT SSH PUBLIC KEY button when done to save it.

Note

Ensure you paste the public key into the field. It has an extension of ”.pub”

Now that you’ve uploaded your key, you can launch a server and connect to it using an SSH client like PuTTY or Terminal.
