To log in, you'll need your User and IP Address of the instance.
Using Mac & Linux
First, create a key pair. You can create these within the DreamCompute dashboard, or on your local computer:
If you created the Key pair in the DreamCompute dashboard
If you created the Key pair in the dashboard, a .pem file was automatically downloaded to your computer. Move that file into your ~/.ssh/ directory.
For example, let's say you named the Key pair dashboardkey when creating it in the panel. A file named dashboardkey.pem was downloaded.
- Move that from your /Downloads directory into your ~/.ssh directory:
[macbook]$ mv ~/Downloads/dashboardkey.pem ~/.ssh
- Change the permissions to 600
[macbook]$ chmod 600 ~/.ssh/dashboardkey.pem
- You can now log in while specifying that file name:
[macbook]$ ssh -i ~/.ssh/dashboardkey.pem USER@IP_ADDRESS
If you created the Key pair on your local computer
If you created the Key pair on your local computer you now have a private and public key file in the ~/.ssh directory. For example:
[macbook]$ ls -la ~/.ssh id_rsa id_rsa.pub
You can now log in by running the following (make sure to change it to your IP address as shown above):
[macbook]$ ssh USER@IP_ADDRESS
What if I didn't name the Key pair id_rsa?
When you created the Key pair, you could name it anything you like. For example, let's say you named it dhc_key in step#1 by running the following:
[user@instance]$ ssh-keygen -t rsa
- This creates a public/private keypair of the type (-t) rsa.
Generating a public/private rsa key pair. Enter the file in which you wish to save they key (i.e., /home/username/.ssh/id_rsa):/home/username/.ssh/dhc_key/
You now must specify the name of the key while logging in. For example:
[user@instance]$ ssh -i ~/.ssh/dhc_key USER@IP_ADDRESS
Using a ~.ssh/config file to simplify logging in
You can also create a 'config' file to simplify the ssh login process. For example, you can simplify your login to something like
- Create a config file in your ~/.ssh directory.
- Edit the file to add the following:
- Host: This is the shortcut name of your connection
- HostName: This is the IP Address of your DreamCompute instance
- User: This is the username of your DreamCompute instance
- IdentityFile: This is necessary if your private key is named something other than id_rsa
- Here is a full example of what a ~/.ssh/config file would look like. This example assumes the private key was downloaded from the panel as a .pem file and the username is 'ubuntu'.
Host dhc HostName 18.104.22.168 User ubuntu IdentityFile ~/.ssh/dashboardkey.pem
- You can now log into your instance with the following command
[user@instance]$ ssh dhc
