This article will guide you through the process of generating SSH
keys in Chrome OS Terminal, importing them to the Cloudzy Portal, and
establishing a secure connection to your Linux VPS. By embracing SSH
keys, you can bolster your server’s security, simplify remote access,
and efficiently manage your VPS through the Chrome OS command-line
interface. Let’s embark on a journey into the world of SSH keys,
harnessing their potential for secure and streamlined server
management.
Install ChromeOS
Terminal
To enable the Terminal on Chrome OS, begin by navigating to the
ChromeOS settings. In the “Linux” section, turn on the Linux feature.
This action will prompt a window with a series of installation prompts.
Choose your preferred username and disk size, then click “Install” to
initiate the process. Once the installation is complete, a Terminal
window will open, ready for use.
When you launch the Terminal for the first time, you’ll notice that
the window opens immediately and displays the progress of starting up
the Linux container. With the Terminal installed and operational, you
can now proceed with generating SSH keys, importing them to the Cloudzy
Portal, and establishing secure connections to your Linux VPS instances.
Let’s continue our journey towards secure and efficient server
management using SSH keys in Chrome OS Terminal.
Understanding
Terminal in Chrome OS
Chrome OS provides a powerful terminal application, allowing users to
access a text-based command-line interface to the underlying Linux
shell. Chrome OS Terminal empowers users to interact directly with the
operating system, enabling a wide range of tasks and system
operations.
To open the Chrome OS Terminal, Press Ctrl + Alt + T
to launch the Terminal application.
With Chrome OS Terminal at your disposal, you gain the power to
execute various commands efficiently, making it an indispensable tool
for SSH key generation and VPS management.
Generating SSH Keys on
Chrome OS
SSH keys comprise a pair of cryptographic keys—a private key (kept
confidential) and a public key (used for authentication). Generating SSH
keys on Chrome OS Terminal is a straightforward process:
-
Launch the Chrome OS Terminal by pressing Ctrl + Alt +
T. -
Execute the following command in the Terminal window:
ssh-keygen -t rsa- The key generation process will prompt you to specify the storage
location for the keys. Accept the default location by pressing the ENTER
key, and set a passphrase for enhanced security (not recommended to skip
this step).
⚠️Warning! You will need to enter the passphrase twice to
continue.
- After confirming the passphrase, the system generates the key
pair.
After confirming the passphrase, the system generates the key pair.
Your identification has been saved in /home/your_username/.ssh/id_rsa.
Your public key has been saved in /home/your_username/.ssh/id_rsa.pub.
The key fingerprint is:
ae:89:72:0b:85:da:ta:b4:8c:1f:c2:43:fd:c6:47:87 [email protected]
The key's random art image is:
+--[ RSA 2048]----+

| . |
| E . |
| . . o |
| o . . S . |
| + + o . + |
|. + o = o + |
| o...o * o |
|. oo.o . |
+-----------------+- Your private key is saved to the id_rsa file in the .ssh directory,
while the public key is stored in id_rsa.pub.
⚠️Important: Never share your private key with
anyone!
- Save the public key to your clipboard by running this command:
cat ~/.ssh/id_rsa.pub-
The extensive key will manifest, replete with letters, numbers,
and intermittent + symbols. The commencement of this
prolonged key is indicated by: ssh-rsa. The [email protected]
address will be at the tail end of the key, constituting a component of
it. -
From the ssh-rsa prefix onward, select and encompass the complete
key using your cursor. Upon releasing the cursor, an ephemeral
notification reading Copied will briefly materialize on
the screen.
Importing
Your SSH Key to the Cloudzy Portal
Now, import the copied SSH key to the Cloudzy Portal for secure
server management:
-
After copying the SSH key to the clipboard, log in to your
Cloudzy account page. -
In the left sidebar, choose SSH Keys and click
on NEW SSH KEY in the top right corner. -
Name your key descriptively and paste the contents of the public
key into the Public Key area.
With your SSH key successfully imported, you’re well-prepared for
streamlined VPS creation and heightened server security.
Connecting
to Your VPS Server via Chrome OS Terminal
Now, let’s delve into the process of establishing a secure connection
to your VPS server using the Chrome OS Terminal, with a deeper look at
the -i option for added security:
-
Launch the Chrome OS Terminal by pressing Ctrl + Alt +
T. -
Compose the following command in the terminal, ensuring you
replace username with your VPS server’s username and
your_server_ip with your VPS’s IP address or domain
name:
ssh username@your_server_ip- If this is your first connection, confirm the host authenticity and
enter the passphrase you set for your SSH key during generation.
Introducing the -i Option: To enhance the security
of your connection, you can utilize the -i option followed by the path
to your private SSH key. This key-based authentication adds an extra
layer of protection by ensuring that only those with the private key can
access the server.
ssh -i /home/your_username/.ssh/id_rsa username@your_server_ipBy implementing the -i option and specifying the full path to your
private SSH key, you’re bolstering the security of your connection.
By harnessing the power of SSH keys and Chrome OS Terminal, you have
unlocked a secure and efficient approach to connecting and managing your
Linux VPS. Through the process of generating SSH keys, importing them to
the Cloudzy Portal, and establishing connections via Terminal, you have
fortified your server’s security and simplified remote management.
