How to Connect to Linux VPS Using SSH Keys in iOS with xTerminal

While iOS does not provide a built-in SSH client for connecting to Linux servers, you can use third-party applications like the xTerminal SSH client. By following these steps, you can enhance your server's security and efficiently manage your VPS, all from the convenience of your iOS device.

Generating SSH Keys

Before utilizing xTerminal to connect to your Linux VPS securely, you should generate SSH keys on your Windows, macOS, or Linux computer. Follow these step-by-step instructions to generate SSH keys:

1. Launch Your Computer's Terminal Application

On Windows, you can use applications like, PowerShell, or CMD. On macOS and Linux, open the terminal application.

2. Execute the SSH Key Generation Command

In the terminal, enter the following command to generate your SSH keys:


ssh-keygen -t rsa

3. Set the Key Storage Location

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.

4. The Key Pair is Generated

After confirming the passphrase, the system generates the key pair.

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!

5. 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, return 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 id_rsa.pub contents into the Public Key area.

With your SSH key successfully imported, you're well-prepared for streamlined VPS creation and heightened server security.

Installing xTerminal

To connect to your Linux VPS with SSH keys on your iOS device, install xTerminal from the App Store by following these steps:

Download xTerminal from the App Store: xTerminal on App Store

Importing Private SSH Keys to xTerminal

Now that xTerminal is installed on your iOS device, you can import the SSH private keys generated earlier. Here's how:

Launch xTerminal on your iOS device.
From the app's home page, choose Add a server.

Fill in the required fields like Name, Host IP, and Username (e.g., root).
Instead of entering a password, choose the Key button.
You will be redirected to the Keys page. Choose Add a Key.
Select a name for your key and copy and paste the contents of your private key file (id_rsa).

If you secured your private key with a passphrase, enter it in the designated field.
Finally, choose Save twice to complete the process

Connecting to Your Linux VPS

With your SSH keys imported, you're ready to connect to your Linux VPS using xTerminal. Follow these steps:

Launch xTerminal on your iOS device.
From the app's home page, select the server you added earlier.
xTerminal will automatically use your imported SSH keys for authentication.
Enter your SSH key passphrase (if applicable) and tap on Connect.
