The security of your device becomes your responsibility. If you have a jailbroken iPhone, or are thinking about jailbreaking your device, there are some safety guidelines you should keep in mind.
Nagios Remote Plug-in Executor (NRPE), a product of Nagios monitoring software, is used for monitoring network services and resources in remote Linux and Unix host systems, such as CPU load, disk space usage, memory usage and number of logged-in users. This event handler is managed remotely once the NRPE daemon is installed in the remote machine. The low CPU load NRPE imposes makes it an often-preferred method for monitoring a large quantity of remote systems. "Connection Refused" errors often occur when the NRPE daemon runs a command that takes longer than the established timeout limit. You can change the NRPE…
Jailbroken Apple iPhones have two administrator accounts, using the username's root and mobile, with both accounts having the default password “alpine.” This creates a security risk, as it allows anyone to connect to the phone through SSH as the admin user. Because of this risk, it is advisable to change your root password to something unique if you have not already done so. Accomplish this using the free Putty SSH client.
The GNU Grub bootloader is used on most modern Linux operating systems as the software program that the computer's hardware uses to boot Linux when you power on the machine. If you want to edit Grub to change the boot options, you can do so by using the Linux system's built-in text editor.

The file consists of text that delineates options for how to configure the Linux installation on each of the target machines.
UNIX operating systems such as Oracle Solaris, IBM AIX, and HP-UX all have a root user. The root user is equivalent to the Windows Administrator user and has access to the entire machine. If your password aging is configured, passwords expire after a certain period of time and users are prompted to select a new password when they log in. You can log in as root directly at the login prompt or use the "su" command to become the root user when logged in as another user. The "su" command can't be used to become the root user when its…

However, if you do enable the root user, you can always change the password.

The assumption for Linux and Unix systems, including Fedora Core 3, is that if you have control of the computer you own the machine. In other words, if you are sitting at the actual machine, you can change the root password. Historically, Unix machines were used as servers and users logged in from remote locations. Only the system administrators could access the root account. This still holds true. If you are sitting at the actual machine, you can boot into single-user mode and change a forgotten root password.
The root user on your SUSE Linux system has the ability to modify anything they desire. They can reset passwords, change settings and even erase the entire hard drive in a single command.

A "root" user is a special user account on UNIX-based systems that has read and write access to all parts of the system, including all user accounts. An "admin" account, by contrast, can use the Server Admin and Macintosh Manager applications--"root" cannot--but does not have systemwide read/write access. Any user with admin access can also change the root password, so be very careful to whom you grant this privileged access. The "root" user is disabled by default on most MacBooks, although if you use Mac OS X Server, the root account will be enabled.
The MySQL database application has an administrator account called "root." This user has complete administrative control over all aspects of the database. This user also should have a very secure password and the password should be changed regularly. There are two ways to change the root password. The "Mysqladmin" command is used to change the password from outside the MySQL database. The "Update" statement is a SQL command and is issued after you are logged into the database.
If you've bought a used Mac you may not know the root password. The root user and password is also called the system administrator user and password. The root password is typically required when installing software to a Mac or making changes to the computer's system preferences.
