root user root的意思|示意

The quickest way to check whether at could be made to run by a non-root user without being setuid root is to remove the setuid bit and then grant it all capabilities.

要想查明非根用户是否可以运行不带 setuid 位的 at，最快的方法是删除 setuid 位，然后授予所有能力

Enter root as the user name and the root password as the password.

请输入root作为用户名，并使用root密码作为密码。

One way to avoid this problem is to never log in to the system as the root user (see the Logging in as root section).

避免这个问题的方法之一是，不要以root用户登录到系统中(请参见以root用户登录部分)。

For example, a program that needs a single root privilege may get started as root (say, by being setuid root) and then switch to running as a less-privileged user.

例如，需要个别的root特权的程序可能以root身份启动(比如说，通过成为setuid root)然后切换到以较少特权用户身份运行。

This approach allows administrators to keep control of where user root can SSH to, thus keeping control on root remote connections.

这种方式让管理员可以控制root用户能够从哪里通过SSH连接，由此控制远程root连接。

When dealing with direct root SSH access from remote hosts, I suggest it is best to limit which hosts can SSH in as user root.

在处理来自远程主机的直接root SSH访问时，我建议最好限制能够作为root用户通过SSH连接的主机。
