如何对 IPoIB 网络使用 nmap？

  • 772

我正在尝试使用它nmap来检查给定网络上正在运行哪些服务，但它无法启动只是因为nmap在 IPv4 网络和 Infiniband 网络上发出 ARP Ping 扫描，据我所知，没有 ARP，因为广播不是支持，但如果您使用的是 IPoIB（IP over Infiniband），则您有 IP 寻址。

我可以确认 IP 网络正常工作，因为我可以正常工作ping，ssh以及其他一切，但nmap失败了。

这是输出：

# nmap 172.27.0.1-21 -v

确认网络正常：

ping 172.27.0.10

还有TCP：

如何nmap在 IPoIB 网络上使用？

arp

    我想通了。-sTflag 成功了，但由于我仍然不明白它只适用于-P0or 的原因-Pn。

    因为我只关心 TCP 服务，所以在这种情况下-sT就足够了。

    同样重要的是要观察-P0or -Pnalone 也表示主机已关闭。

    所以最后的命令是这样的 nmap -e ib0 <IP_ADDRESS> -v -sT -P0：
