Kali2020 ifconfig命令找不到解决方案

来源：微信公众号「编程学习基地」

Kali2020 缺少ifconfig命令

这个是因为kali安装是时候没有安装net-tools工具包

sudo apt-get install net-tools

安装完成之后发现还是有问题

还是输入没有命令

因为2020版的默认登录不是root用户所以加上sudo

sudo ifconfig

这样很麻烦，每次ifconfig都要输入密码

解决方案

找到ifconfig这个程序，通过绝对路径运行ifconfig程序

deroy@kali:~/桌面$ sudo which ifconfig
/usr/sbin/ifconfig
deroy@kali:~/桌面$ /usr/sbin/ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
...

添加环境变量

• 编辑~/.bashec文件

vim ~/.bashrc

• 末尾加入下面内容

export PATH=/usr/sbin/:$PATH

• 更新~/.bashec文件

	source ~/.bashrc

• 再次执行ifconfig命令

eroy@kali:~/桌面$ ifconfig
