feat: v2.1.0 核心重构与功能增强
## 架构重构
- 全局变量消除,迁移至 Config/State 对象
- SMB 插件融合(smb/smb2/smbghost/smbinfo)
- 服务探测重构,实现 Nmap 风格 fallback 机制
- 输出系统重构,TXT 实时刷盘 + 双写机制
- i18n 框架升级至 go-i18n
## 性能优化
- 正则表达式预编译
- 内存优化 map[string]struct{}
- 并发指纹匹配
- SOCKS5 连接复用
- 滑动窗口调度 + 自适应线程池
## 新功能
- Web 管理界面
- 多格式 POC 适配(xray/afrog)
- 增强指纹库(3139条)
- Favicon hash 指纹识别
- 插件选择性编译(Build Tags)
- fscan-lab 靶场环境
- 默认端口扩展(62→133)
## 构建系统
- 添加 no_local tag 支持排除本地插件
- 多版本构建:fscan/fscan-nolocal/fscan-web
- CI 添加 snapshot 模式支持仅测试构建
## Bug 修复
- 修复 120+ 个问题,包括 RDP panic、批量扫描漏报、
JSON 输出格式、Redis 检测、Context 超时等
## 测试增强
- 单元测试覆盖率 74-100%
- 并发安全测试
- 集成测试(Web/端口/服务/SSH/ICMP)

# fscan-lite
|
||||
|
||||
极简但极致兼容的TCP内网端口扫描器
|
||||
|
||||
## 设计理念
|
||||
|
||||
**兼容性第一,简洁至上**
|
||||
|
||||
- 支持从 Windows 98 到 Windows 11
|
||||
- 支持从 Ubuntu 8.04 到最新版本
|
||||
- 使用 C89 标准,最大兼容性
|
||||
- 静态编译,零依赖运行
|
||||
- 单个可执行文件 < 1MB
|
||||
|
||||
## 功能特性
|
||||
|
||||
- ✅ TCP端口连接扫描
|
||||
- ✅ 支持端口范围 (1-65535, 80,443)
|
||||
- ✅ 可配置超时时间
|
||||
- ✅ 静态编译,零依赖
|
||||
- ✅ 跨平台兼容
|
||||
|
||||
## 编译
|
||||
|
||||
### Linux/Unix
|
||||
|
||||
```bash
|
||||
# 动态编译
|
||||
make
|
||||
|
||||
# 静态编译(推荐)
|
||||
make static
|
||||
|
||||
# 最小化编译
|
||||
make small
|
||||
```
|
||||
|
||||
### Windows
|
||||
|
||||
```bash
|
||||
# MinGW 编译
|
||||
mingw32-make -f Makefile
|
||||
|
||||
# 或使用MSVC
|
||||
cl /TC src/*.c /Febin/fscan-lite.exe ws2_32.lib
|
||||
```
|
||||
|
||||
## 使用方法
|
||||
|
||||
```bash
|
||||
# 基本用法
|
||||
./bin/fscan-lite -h 192.168.1.1 -p 22,80,443
|
||||
|
||||
# 扫描端口范围
|
||||
./bin/fscan-lite -h 10.0.0.1 -p 1-1000
|
||||
|
||||
# 自定义超时
|
||||
./bin/fscan-lite -h 192.168.1.100 -p 80,443 -t 2
|
||||
```
|
||||
|
||||
## 参数说明
|
||||
|
||||
| 参数 | 说明 | 示例 |
|
||||
|------|------|------|
|
||||
| -h HOST | 目标主机IP | -h 192.168.1.1 |
|
||||
| -p PORTS | 端口列表 | -p 80,443,8000-8080 |
|
||||
| -t TIMEOUT | 超时时间(秒) | -t 3 |
|
||||
| --help | 显示帮助 | --help |
|
||||
| --version | 显示版本 | --version |
|
||||
|
||||
## 二进制大小对比
|
||||
|
||||
| 版本 | 大小 | 说明 |
|
||||
|------|------|------|
|
||||
| fscan (Go) | ~30MB | 包含运行时 |
|
||||
| fscan-lite | ~900KB | 静态编译 |
|
||||
| fscan-lite (strip) | ~700KB | 去除调试信息 |
|
||||
|
||||
## 兼容性测试
|
||||
|
||||
### Linux 发行版
|
||||
- ✅ Ubuntu 8.04 - 24.04
|
||||
- ✅ CentOS 5 - 9
|
||||
- ✅ Debian 5 - 12
|
||||
- ✅ RHEL 5 - 9
|
||||
|
||||

|
||||
- ✅ Windows XP
|
||||
- ✅ Windows 7/8/10/11
|
||||
- ✅ Windows Server 2003-2022
|
||||
|
||||
## 技术实现
|
||||
|
||||
- **语言**: C89 (最大兼容性)
|
||||
- **网络**: 原生socket API
|
||||
- **编译**: GCC/MSVC/Clang
|
||||
- **链接**: 静态链接,零依赖
|
||||
- **大小**: < 1MB 单文件
|
||||
|
||||
## 性能对比
|
||||
|
||||
| 指标 | fscan | fscan-lite |
|
||||
|------|-------|------------|
|
||||
| 启动时间 | ~50ms | ~5ms |
|
||||
| 内存占用 | ~20MB | ~2MB |
|
||||
| 扫描速度 | 1000 ports/s | 1000 ports/s |
|
||||
| 兼容性 | 现代系统 | 25年跨度 |
|
||||
|
||||
## 构建配置
|
||||
|
||||
```bash
|
||||
# 查看构建信息
|
||||
make info
|
||||
|
||||
# 所有构建选项
|
||||
make help
|
||||
```
|
||||
|
||||
## 许可证
|
||||
|
||||
与 fscan 主项目保持一致
|
||||
|
||||
---
|
||||
|
||||
**理念**: 一个工具应该在它设计的任何系统上都能运行,而不需要用户去寻找依赖项。
