Linux-ARP Router Project

Overview

This project is a Linux-based router experiment system written in C. It features ARP cache management, IP filtering, network interface information retrieval, and multi-threaded packet processing. The code is modular, with separate files for ARP/IP list management, thread handling, and interface operations.

Features

• ARP cache linked list management (add, delete, search, print)
• IP filter linked list management
• Multi-threaded packet processing using pthreads
• Network interface information retrieval
• Configurable via CMake or Makefile

Build & Run

# Using CMake
mkdir build && cd build
cmake ..
make
./router

# Or using Makefile
make
./router

File Structure

• main.c - Program entry, thread creation, system initialization
• arp_link.* - ARP cache linked list logic
• ip_link.* - IP filter linked list logic
• get_interface.* - Network interface info
• arp_pthread.c, ip_pthread.c, key_thread.c - Thread logic

Requirements

• Linux OS
• GCC
• pthread library

Linux-ARP 路由器项目

项目简介

本项目为基于C语言的Linux路由器实验系统，实现了ARP缓存管理、IP过滤、网络接口信息获取及多线程数据包处理。代码结构清晰，功能模块独立，便于学习和扩展。

主要功能

• ARP缓存链表管理（增删查打印）
• IP过滤链表管理
• 基于pthread的多线程数据包处理
• 网络接口信息获取
• 支持CMake和Makefile构建

编译与运行

# 使用CMake
mkdir build && cd build
cmake ..
make
./router

# 或直接使用Makefile
make
./router

目录结构

• main.c - 主程序入口，线程创建与系统初始化
• arp_link.* - ARP链表管理
• ip_link.* - IP过滤链表管理
• get_interface.* - 网络接口信息
• arp_pthread.c、ip_pthread.c、key_thread.c - 线程处理逻辑

依赖环境

• Linux操作系统
• GCC编译器
• pthread库
