3个过程全部完成叫全开扫描，最后一步不做，叫半开扫描。在实际过程中，半开扫描应用的最多，半开扫描不容易被目标电脑日志记录。半开扫描需要加参数-sS，全开扫描需要加参数-sT。
半开扫描：nmap -sS 192.168.152.130
全开扫描：nmap -sT 192.168.152.130

仅使用Ping协议进行主机发现
nmap -sP nmap -PN 10.106.19.75/24
跳过Ping扫描阶段（无ping扫描）
nmap -PN 10.106.19.75/24
ARP协议扫描只适用于局域网内，使用ARP，不仅速度快，而且结果也会更加准确。
nmap -PR 10.106.19.75/24
