How to connect Linux VPS using Putty?

A VPS, short for virtual private server’, is a virtual machine with hardware resources dedicated to you. One of the key advantages of this solution is its cost, as it is has a much more affordable price tag than a standard dedicated server.

Linux VPS can be connected using SSH, Command line or terminal or you can also use SSH applications like Putty or mRemote application. Currently in this blog, we are discussing how you can connect your Linux vps using putty. Here’s a step-by-step guide on how to connect to your Linux VPS using PuTTY:

Before you begin:

Make sure you have your VPS’s IP address, username, and password readily available. You should have received these details on your email id.

Download and install PuTTY from the official website: https://www.putty.org/

Step 1: Open PuTTY: Launch the PuTTY application on your computer.

Step 2. Enter connection details: In the “Host Name (or IP address)” field, enter the IP address of your VPS.

Step 3: Select “SSH” under “Connection type”.

Step 4: Leave the remaining settings on their default values unless specified or guided by your System Administrator.

Step 5: Establish connection: Click the “Open” button.

Step 6: Security key confirmation: The first time you connect to a server, PuTTY might display a security key confirmation message. This is normal. Click “Yes” to accept and save the key.

Step 7: User login: You will be prompted to enter your username. Type your VPS username and press Enter.

Step 8: Password and authentication: Enter your VPS password. Note: You won’t see the password characters as you type for security reasons. Press Enter again.

Successful connection: If the credentials are correct, you’ll be logged in to your VPS and see a terminal window displaying the VPS command prompt.

Additional notes:

Alternative authentication: Consider using SSH key pair authentication for increased security. This method eliminates the need to type your password every time you connect.

Troubleshooting: If you encounter any issues connecting, double-check your credentials and firewall settings. Ensure SSH is enabled on your VPS. Consider referring to your VPS provider’s documentation for further assistance.

For your safety:

Never share your VPS credentials with anyone.

What is a Web Server ? How Web Servers Work ?

Understanding Web Servers: A Comprehensive Guide

Introduction:

A web server is a critical component of the internet infrastructure, serving as the backbone for the delivery of web content. It acts as an intermediary between clients, typically web browsers, and the resources they request, such as web pages, images, or files. The functioning of a web server involves a series of steps, from receiving a client request to delivering the requested content. This guide will explore the intricacies of web servers, delving into their definition, how they work, key components, protocols, security considerations, and examples.

I. Definition and Purpose:

A. What is a Web Server?

A web server is a specialized software or hardware designed to handle incoming requests over the HTTP (Hypertext Transfer Protocol) or HTTPS (HTTP Secure) protocols. Its primary function is to process these requests and deliver the requested web content to clients. Web servers are an integral part of the client-server model in network communication, where clients initiate requests, and servers respond to those requests.

B. Purpose of Web Servers:

The fundamental purpose of a web server is to facilitate the exchange of information between clients and servers on the World Wide Web. When a user enters a URL in a web browser or clicks on a link, a series of interactions occur between the client and the server. The web server processes these requests, retrieves the requested resources, and sends them back to the client for rendering.

II. How Web Servers Work:

The operation of a web server involves several stages, each contributing to the seamless delivery of web content.

A. Client Request:

The process begins with a user initiating a request by entering a Uniform Resource Locator (URL) into a web browser or clicking on a hyperlink. This action triggers a request for a specific resource hosted on a web server.

B. DNS Resolution:

The entered URL is a human-readable domain name. The browser uses the Domain Name System (DNS) to translate this domain name into an IP address, allowing the browser to locate the server on the internet.

C. Connection Establishment:

Armed with the IP address obtained from DNS, the browser establishes a connection to the web server. This connection is typically established over the Transmission Control Protocol (TCP).

D. HTTP Request:

Once the connection is established, the browser sends an HTTP request to the web server. This request specifies the resource (e.g., a web page or an image) the client is seeking.

E. Web Server Processing:

Upon receiving the request, the web server processes it. This may involve retrieving a static resource directly from the server’s file system or dynamically generating content based on the request, often using server-side scripting languages like PHP or Python.

F. HTTP Response:

Having processed the request, the web server sends back an HTTP response to the client. This response contains the requested content or an error message if the resource is unavailable.

G. Rendering:

The browser receives the HTTP response and renders the web page or displays the resource, providing the user with the intended content.

III. Key Components of Web Servers:

Web servers consist of several components, each playing a crucial role in their functionality.

A. Software Components:

  1. HTTP Server Software:
    • The core of a web server is the HTTP server software. Examples include Apache HTTP Server, Nginx, Microsoft Internet Information Services (IIS), and LiteSpeed.
  2. Server-Side Scripting Engines:
    • For dynamic content generation, web servers often incorporate server-side scripting engines like PHP, Python, or Ruby.
  3. Configuration Files:
    • Web servers use configuration files to define settings such as server port, document root, security configurations, and more. For instance, Apache uses the httpd.conf file.
  4. Modules:
    • Many web servers support modular architecture, allowing users to extend functionality. Modules can add features like authentication, URL rewriting, or support for specific programming languages.

B. Hardware Components:

  1. Processor (CPU):
    • The processor handles the execution of instructions and plays a crucial role in a server’s overall performance.
  2. Memory (RAM):
    • Random Access Memory is essential for storing and quickly accessing data that the server needs to process requests.
  3. Storage:
    • Web servers store web content, configuration files, and other data on storage devices such as hard drives or solid-state drives.
  4. Network Interface Card (NIC):
