结果如上图, 笔者用的是VMWare, 运行的是Kali Linux, 希望用桥接模式通过路由器获取动态IP, 但是无论如何也不能正确获取IP地址.
一点点排查
1. 排查DNS
root@kali:~# cat /etc/resolv.conf
nameserver 192.168.1.1
nameserver 114.114.114.114
192.168.1.1在里面, DNS设置没有问题
2. 排查网卡
root@kali:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5). # The loopback network interface
auto lo
iface lo inet loopback # The primary network interface
#allow-hotplug eth0
auto eth0
iface eth0 inet dhcp
网卡自动激活, 并配置dhcp获取IP方式
3.排查VMWare 桥接设置
由于笔者装有Virual Box & VMWare Workstation, 所以有多个虚拟网卡, 桥接为自动模式, 心想是不是自动桥接到不能连外网的Virtual Box的虚拟网卡了?
果断选成实际外网网卡, 重启Kali Linux networking服务, 问题解决.
