导致xshell等其他连接工具无法连接

操作如下

2020版本的kali默认创建的时候没有root账户

sudo -i
密码：你自己创建账号的密码
切换到root账户 获取权限

vim /etc/ssh/sshd_config编辑sshd配置文件

找到#PermitRootLogin prohibit-password，把前面的#去掉，并且将“prohibit-password”修改为YES

找到PasswordAuthentication这一行，将前面的#号注释去掉，如果后面写的是no，需要修改成yes

Esc 退出编辑 ，输入:wq 回车，完成编辑

/etc/init.d/ssh restart

重启成功，进行连接

查看IP

root@kali:~# ip a

shell连接

[E:\Xshell\Sessions]$ ssh 192.168.1.129

设置ssh开机自启
