NO.A.0017.kali-linux2020.4配置固定IP地址/开启root权限/开启ssh服务/配置国内源地址

//1、在普通用户下设置root密码;开启root用户权限
┌──(yanqi㉿kali)-[~]      
└─$ sudo passwd root                                                      130 ⨯
[sudo] password for yanqi:  
New password:        
Retype new password:    
passwd: password updated successfully


//2、在非root账户下，输入当前用户的密码即可开启临时root权限

└─$ sudo -i
[sudo] yanqi 的密码：

//添加静态IP地址（oracle vm virtualBox设置为桥接模式）：
┌──(root💀kali)-[~]        
└─#  vim /etc/network/interfaces
allow-hotplug eth0
auto eth0
iface eth0 inet static
address 192.168.1.96
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameserver 114.114.114.114,8.8.8.8
┌──(root💀kali)-[~]
└─# systemctl restart networking.service

//1、修改ssh服务配置文件，并启动ssh服务
┌──(root💀kali)-[~]      
└─# apt-get install openssh-server openssh-client
┌──(root💀kali)-[~]      
└─# vim /etc/ssh/sshd_config
PermitRootLogin yes
PasswordAuthentication yes
//OR
LoginGraceTime 120
PermitRootLogin yes
StrictModes yes
┌──(root💀kali)-[~]
└─# /etc/init.d/ssh start
┌──(root💀kali)-[~]      
└─# /etc/init.d/ssh status  


//2、若是ssh服务连接不上，生成一下两个秘钥文件,执行命令时需要输入密码，直接回车设置为空即可         
┌──(root💀kali)-[~]

┌──(root💀kali)-[~]
└─# ssh-keygen -t dsa -f /etc/ssh/ssh_host_rsa_key


//3、设置系统自动启动ssh服务
方案一：
┌──(root💀kali)-[~]      
└─# sysv-rc-conf                     
┌──(root💀kali)-[~]
└─# sysv-rc-conf --list | grep ssh
┌──(root💀kali)-[~]        //开启系统自动启动SSH服务
└─# sysv-rc-conf ssh on    
┌──(root💀kali)-[~]        //关闭系统自动启动SSH服务
└─# sysv-rc-conf ssh off
方案二：
┌──(root💀kali)-[~]        //系统自动启动SSH服务  
└─# update-rc.d ssh enable 
┌──(root💀kali)-[~]         // 关闭系统自动启动SSH服务
└─# update-rc.d ssh disabled

┌──(root💀kali)-[~]

└─# apt-get update      
┌──(root💀kali)-[~]

┌──(root💀kali)-[~]          //该命令也是更新所有软件包。
└─# apt-get dist-upgrade      //upgrade更新时；如果依赖关系无法解决可能会报错或者停止，                           
//dist-upgrade命令可以自动解决依赖关系。因此dist-upgrade可能会更新不希望更新的软件，导致一些需要依赖旧包的软件无法运行
//apt-get dist-upgrade慎用。一般使用 apt-get update && apt-get upgrade 可以保证系统的完整性。


//一般我们更新源后对软件进行一次整体更新：分下面三步执行：
┌──(root💀kali)-[~]
└─# apt-get update && apt-get upgrade   //可以保证系统的完整性（upgrade更新，若依赖关系无法解决可能会报错或停止）。
┌──(root💀kali)-[~]            //该命令也是更新所有软件包（慎用：自动解决依赖关系，可能更新一些不需要更新的包，导致一些需要依赖就报的程序无法运行）。
