CScanner

CScanner is a simple yet efficient port scanner written in C. This tool allows users to check if specific ports are open on a target IP address, which is useful for network security audits and troubleshooting.

Features

• Fast scanning for open ports
• Lightweight and minimal dependencies
• Easy-to-use command-line interface

Installation

Prerequisites

• C compiler: You’ll need a C compiler (e.g., GCC or Clang) installed on your system.
• Make (optional but recommended): To streamline the build process, especially for larger projects.

Compiling CScanner

1. Clone the Repository:

git clone https://github.com/yourusername/CScanner.git
cd CScanner

Compile: Use the following commands to compile the program.

With GCC:

gcc -o main main.c

With Clang (optional):

clang -o main main.c

Run the Program

After compilation, you should have an executable named main.exe (or simply main on Unix-based systems).

Usage

To run the CScanner, use the following syntax:

./main <ip> <port>

• : The IP address of the target you want to scan.
• : The specific port number you want to check. If the port is open, CScanner will output a success message; otherwise, it will indicate the port is closed or unreachable.

Examples

To scan port 80 on 192.168.1.1:

./main 192.168.1.1 80

To scan a different port, simply replace the port number:

./main 192.168.1.1 443

Notes

Ensure you have the necessary permissions to scan ports on the network you are analyzing. Running this tool on public networks may require authorization to avoid breaching security policies.
