问题场景
之前有热心网友提问，自己的kali为什么连不上网？ping自己的主机也ping不通？
方案一
联网使用的是NAT模式
我们可以通过下面方式进行修改
网卡配置
修改/etc/network/interfaces
mousepad /etc/network/interfaces配置文件如下
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
DNS配置
修改/etc/resolv.conf
mousepad /etc/resolv.conf配置文件如下
# Generated by NetworkManager
search localdomain
nameserver 114.114.114.114
nameserver 8.8.8.8
部分热心网友看了网上的一些教程，就无脑的去设置了静态地址，从而导致无法联网、也无法ping通主机……
方案二
部分网友发现可以联的上网，但是ping不通内网的机器，这时，你可能需要使用下面的命令
route -n找到错误的链路，然后把它删掉
route delete -net X.X.X.X netmask X.X.X.X举个例子
[root@kali ~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default gateway 0.0.0.0 UG 100 0 0 eth0
10.0.2.0 0.0.0.0 255.255.255.0 U 100 0 0 eth0
10.244.0.0 0.0.0.0 255.255.255.0 U 0 0 0 cni0
10.244.1.0 10.244.1.0 255.255.255.0 UG 0 0 0 flannel.1
10.244.2.0 10.244.2.0 255.255.255.0 UG 0 0 0 flannel.1
link-local 0.0.0.0 255.255.0.0 U 1003 0 0 eth1
172.17.0.0 0.0.0.0 255.255.0.0 U 0 0 0 docker0
172.18.0.0 0.0.0.0 255.255.0.0 U 0 0 0 br-fc0843e5ca0a
192.168.8.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
需要删除这里的docker0链路
[root@kali ~]# route del -net 172.17.0.0 netmask 255.255.0.0 方案三
很多学生配置实验需要在IP中携带自己的学号，导致kali被整的很乱，这时，你可以找到一种暴力的手段
那就是虚拟网络编辑器一键还原，这样就没有烦恼了
