FTP stands for File Transfer Protocol, a way to move files between computers on a network. You can use it to send files from one computer to another, like swapping photos or documents. It's kind of like mailing packages but for digital stuff. In this article, we will discuss what is an FTP server, and how to secure an FTP server. We’ll also discuss the requirements for installing an FTP server, and the procedures for installing, configuring, and setting up an FTP server.

What is an FTP Server?

FTP (File Transfer Protocol) server is like a digital warehouse where you can store and exchange files over the internet. Just like how you might send files through email, an FTP server lets you upload and download files, but it's typically faster and more efficient for large files or lots of files at once. It's commonly used by businesses, organizations, and even individuals to share files securely and easily between computers or servers over the internet. Think of it as a virtual storage space where you can move files back and forth between different computers or devices.

Requirements for Setting Up an FTP Server

Server: You will need a server to host the Git server. This can be a physical server or a virtual private server (VPS).
Operating System: CentOS/RHEL is the recommended operating system for hosting vsftpd due to its stability and reliability.
vsftpd Installation: Install vsftpd on your server using the package manager, ensuring that you have access to the latest version of the software.
SSH Access: Secure Shell (SSH) access to your server is necessary for configuring and managing the vsftpd server remotely.
Web Server: While not mandatory, installing a web server like Apache or Nginx can enhance the FTP server's functionality, especially for serving files over HTTP(S)

How to Install a vsftpd on Linux

To Install vsftpd on CentOS/RHEL, simply follow these steps:
1. You can easily install VSFTPD on your CentOS/Red Hat servers via the command line interface using the following commands:
sudo dnf install vsftpd
sudo yum install vsftpd

Setting Up FTP Server Configuration

To configure vsftpd on CentOS/RHEL, do the following steps:
1. Locate vsftpd configuration file: The vsftpd configuration file is typically found at /etc/vsftpd.conf.
man vsftpd.conf
2. Modify vsftpd Configuration: Simply use any text editor to edit the vsftpd configuration file located at /etc/vsftpd.conf.
nano /etc/vsftpd/vsftpd.conf
3. Enable Uploading: To allow uploading files just set the "write_enable" option to YES in the vsftpd configuration file. If it's already there but has a "#" in front, just remove the "#" to activate it.
write_enable=YES
4. Allow Local Users to Log In: To let local users log in, simply set the "local____enable" option to YES in the vsftpd configuration file. This enables users listed in /etc/passwd to access the FTP server.
local_enable=YES

How to Start the Service

To start vsftpd service on CentOS/RHEL, do the following steps:
1. Start the Service: Activate the vsftpd service by executing sudo systemctl start vsftpd.
2. Enable Autostart: Ensure that vsftpd starts automatically upon system boot with
sudo systemctl enable vsftpd

Securing the FTP Server

Firewall Configuration: Open ports 20 and 21 in the firewall to enable FTP connections.
User Authentication: Use strong authentication methods to ensure only authorized users access the FTP server.
Monitoring and Logging: Keep an eye on vsftpd logs for any unusual activities and set up logging for security checks.

Importance of Utilizing an FTP Server

In conclusion, establishing a secure FTP server with vsftpd on CentOS/RHEL enables efficient and secure file transfers over the internet.

C++ was created by Danish computer scientist Bjarne Stroustrup, and first released in 1985 as an extension of the C programming language. In this article, we'll explain what C++ is, and how to download, install, and use C++ 20 (the latest version of C++) on Windows and Linux operating systems. We'll also discuss the steps on how beginners can learn C++.

What is C++

C++ is a general-purpose programming that is mostly implemented as a compiled language, which means users would need a separate compiler to translate its code. C++ offers a balance between high-level abstraction and low-level control, making it a popular choice for developers who need performance and productivity. It is used for developing a wide range of applications, including finance, systems programming, game development, and high-performance applications.

Downloading a C++ Compiler

You need a compiler that can translate your code into machine language. The C++ official site provides free compilers at https://isocpp.org/get-started.

In the Get Started page is a list of compilers. Select and click to download the compiler that is appropriate for your operating system.

The Visual C++ 2017 Community link leads to the Visual Studio Integrated Development Environment (IDE) page which is updated for 2022, and has the necessary components to install and run C++ on your Windows system. The GNU Compiler Collection (GCC) is one of the most popular compilers for Linux system users. Once you download the installer file on your computer, make sure to follow the on-screen instructions.

Downloading, Installing and Using C++20 on Windows

Do the following steps:
1. Go to the Visual Studio IDE for C++ page. Click on the Download Visual Studio with C++ dropdown list.

2. Scroll down on the dropdown list. Click to download the Community 2022 edition.
3. Once the VisualStudioSetup file is downloaded on your computer, double-click or right-click on it. Select Open to install the Visual Studio IDE. Follow all the on-screen instructions.
4. After the installation is complete, launch the Visual Studio application.
5. Select “Create a new project”. Choose “Console App” under “C++” and select a project name and location.
6. Click “Create” to create your C++ project. Select from any of the project templates based on your requirements.
7. In the project settings, make sure the language standard is set to C++20. Navigate to the “Project Properties” or “Project Settings”. Then select the updated version.
8. You can now write C++ code in Visual Studio, and use the IDE to code, debug and run your programs.

Downloading, Installing and Using C++20 on Linux

Do the following steps:
1. To check if the GCC compiler is successfully installed, run the following command:
g++ --version
2. The GCC does not include its own text editor tool. Some of the free code editors that you can download and use are Visual Studio Code, Code::Blocks, Sublime Text, and Geany.
3. Open your preferred code editor. Select “File” > “New Folder”. Choose a project name and location. Save your file with a .cpp extension.
4. To compile your code, press Ctrl+Alt+T on the keyboard to open the Terminal. Go to the directory page where your C++ is saved. Use the following "g++" command to compile the code:
g++ your_program.cpp -o your_program
5. After compiling your code, run the program by using the following command:
./your_program
