What is the difference between WebSocket and SSH?
In the context of a content delivery network, there are several key differences between WebSocket and SSH that should be considered when deciding which protocol to use for communication.
WebSocket is a communication protocol that provides full-duplex, bidirectional communication channels over a single, long-lived TCP connection. It is designed for modern web applications to facilitate real-time data exchange between clients and servers, typically running on browsers and web servers. WebSocket is particularly useful in scenarios where low latency communication is important, such as gaming, instant messaging, or live updates in web applications.
On the other hand, SSH (Secure Shell) is a cryptographic network protocol used primarily for secure remote access to systems and network devices. It establishes an encrypted communication channel between the client and the server, allowing users to administer and operate remote systems securely over a potentially unsecured network.
Here are some of the main differences between WebSocket and SSH in the context of a content delivery network:
1. Purpose: WebSocket is designed for real-time, low latency web applications, while SSH is intended for secure remote access to systems and devices.
2. Encryption: SSH uses strong encryption to protect transmitted data, ensuring confidentiality and integrity of the communication. WebSocket, by itself, doesn’t provide encryption; however, it can be secured using TLS (Transport Layer Security) when using the WebSocket Secure (wss://) protocol.
3. Use Cases: WebSocket is typically employed in web applications requiring real-time interaction, collaboration, or live updates. SSH is more commonly utilized in remote system administration, secure file transfer, and remote command execution.
4. Browser Support: WebSocket is supported natively by all modern browsers. SSH requires additional software, such as an SSH client, to establish a connection from a browser.
In conclusion, while both WebSocket and SSH have their own unique functions and use cases, they serve different purposes in the context of a content delivery network. WebSocket is more suited for real-time data communication in web applications, while SSH is meant for secure remote system access and management.

How to create a SSH account?
In the context of a Content Delivery Network (CDN), creating an SSH account allows you to access your server remotely and securely. This is particularly useful when managing large amounts of data or when deploying applications across multiple geographies. Here are the steps to create an SSH account:
1. Create a new user: First, log in to your server using your root account or an account with root privileges. Then, run the following command to create a new user:
“`
sudo adduser
“`
Replace “ with your preferred username. You will be prompted to enter a password and additional user information.
2. Assign proper permissions: To grant the new user appropriate permissions, add them to the appropriate group. If you want the new user to have root privileges, add them to the sudo group by running:
“`
sudo usermod -aG sudo
“`
3. Set up SSH key-based authentication: To enhance security, it is recommended to use SSH key pairs instead of passwords for authentication. On your local machine, generate an SSH key pair using the following command:
“`
ssh-keygen
“`
This will generate a public and private key pair. The default location for these keys is `~/.ssh/id_rsa` (private key) and `~/.ssh/id_rsa.pub` (public key).
4. Transfer the public key to the server: Use the `ssh-copy-id` command to transfer your public key to the new user’s home directory on the server:
“`
ssh-copy-id @
“`
Replace “ with the new user’s username and “ with your server’s IP address.
5. Configure SSH settings: To ensure secure connections, modify the SSH configuration file on your server. Open `/etc/ssh/sshd_config` using a text editor, and make the following changes:
– Change `PermitRootLogin` to `no` to disable root login via SSH.
– Set `PasswordAuthentication` to `no` to disable password-based authentication.
– Set `AllowUsers` to specify which users are allowed to access the server via SSH.
6. Restart the SSH service: Apply the configuration changes by restarting the SSH service with the following command:
“`
sudo systemctl restart ssh
“`
7. Verify your SSH connection: To test your new SSH account, log in to your server from your local machine using the new user and your server’s IP address:
“`
ssh @
“`
You should now have a secure SSH account that you can use to manage your content delivery network.
