在Kali Linux中启用root账户

永久使用与临时使用

启用Root帐户

首先要做的是设置 root 密码，该密码应该与当前用户的密码不同（在本例中kali）。我们可以通过执行以下操作来做到这一点：

kali@kali:~$ sudo passwd
[sudo] password for kali:
New password:
Retype new password:
passwd: password updated successfully
kali@kali:~$

• 请注意，当您输入密码时，密码提示不会显示输出，但它仍会记录击键。

为 SSH 启用 root

kali@kali:~$ grep PermitRootLogin /etc/ssh/sshd_config
#PermitRootLogin prohibit-password
# the setting of "PermitRootLogin without-password".
kali@kali:~$
kali@kali:~$ man sshd_config | grep -C 1 prohibit-password
     PermitRootLogin
             Specifies whether root can log in using ssh(1).  The argument must be yes, prohibit-password, forced-commands-only, or no.  The default
             is prohibit-password.

             If this option is set to prohibit-password (or its deprecated alias, without-password), password and keyboard-interactive authentication
             are disabled for root.
kali@kali:~$
kali@kali:~$ sudo systemctl restart ssh
kali@kali:~$

如果我们已经为 root 帐户设置了基于 SSH 密钥的登录，那么我们可以简单地取消注释相应的行并继续。否则，我们应该将PermitRootLogin更改为yes，这将允许我们输入密码。

启用 GNOME 和 KDE 登录 root

我们将首先安装kali-root-login并更改多个配置文件，这些文件将允许我们通过 GNOME GDM3 和 KDE 登录提示登录 root 帐户。使用其他桌面环境时不需要此步骤：

kali@kali:~$ sudo apt -y install kali-root-login

• 现在，我们可以注销非 root 用户帐户并使用我们之前设置的密码登录到 root。
