Phase 1: 基本使用

# 单个目标
nerva -t 192.168.1.1:22

# 多个目标
nerva -t 192.168.1.1:22,192.168.1.1:80,192.168.1.1:3306

# 从文件读取
nerva -l targets.txt

# JSON 输出
nerva -t 192.168.1.1:22 --json

Phase 2: 扫描模式

# 快速模式（只尝试默认服务）
nerva -t 192.168.1.1:22 --fast

# UDP 探测
nerva -t 192.168.1.1:161 -U

# 设置超时和并发
nerva -t targets -w 2000 -W 50

# 限速
nerva -l targets.txt -R 100

Phase 3: 管道集成

# naabu 端口扫描 → 服务识别
naabu -host 192.168.1.0/24 -silent | nerva --json

# masscan → 服务识别
sudo masscan 10.0.0.0/24 -p 1-10000 -oL - | \
  grep "^open" | awk '{print $4":"$3}' | nerva --json -o services.json
