In the process of using the Sybase database, we often encounter locks in the Sybase Database System. In most cases, users must log on to the system as Super Users to process the process. To ensure the security of the Sybase Database System, the superuser password is usually in the hands of the database administrator. When the above situation occurs, if the database administrator is absent from the site or cannot handle the problem in other ways, the u

Ubuntu is a Debian-based Linux operating system. By default, there is no superuser (Root), but some system operations must be performed only with the permissions of a Super User, for example, manually release the memory. In other Linux operating systems (such as fedora), you can use Su to switch to a Super User. After the su command is entered, the system requires the root password. However, in Ubuntu, we do not know what the root password is. In this

First unlock root, set password for root user open terminal input: sudo passwd Password: You can then switch to root There are two ways for Su to switch to Superuser: 1.su root: Get the user's temporary permissions, the environment does not change 2.su-root: completely switch to root user

Assuming that we are logged on to a broiler with Terminal Services as Superuser Administrator, first set up an account at the command line or in the Account Manager: hacker$, here I set up this account at the command line. NET user hacker$ 1234/add 2, in the start/Run input: Regedt32.exe and enter to run Regedt32.exe. 3, the point "

I think everyone is familiar with the Regedit.exe, but you can't set permissions on the key keys to the registry, and Regedt32.exe the biggest advantage is the ability to set permissions on key keys in the registry. NT/2000/XP's account information is under the Registry's Hkey_local_machinesamsam key, but other users are not authorized to see the information except system users, so I first set the SAM key to "Regedt32.exe" for me.

Root user, also known as Superuser, is one of the most powerful UNIX accounts, and root accounts can perform any "operations" on any part of the system, including copying files, moving/removing files, executing programs, and so on. As a result, usually Root accounts are assigned only to advanced professional users. As a result, Apple hides root user in Mac OS X. But sometimes we have to enable the root user to do some action, you can use the followin

In the Linux operating system, root is the highest, and is also known as the owner of the Super privilege. The actions that ordinary users cannot perform, which root users can accomplish, are also called Super Admin users. In a system, each file, directory, and process is owned by one user, and no user is permitted to operate on other ordinary users, except for root. Root privileges also show that root can exceed any user and user group to Read, mod

How the permissions system works MySQL privilege system ensures that all users can strictly do what they assume are allowed to do. When you connect to a MySQL server, your identity is determined by the host you connect to and the user name you specify, and the system grants permissions based on your identity and what you want to do. MySQL considers your hostname and user name in its identity because there is a small reason to assume that a given user

When we want to perform permission rating management on a Cisco router or switch, it is often necessary to assign different levels of users a command that exceeds the default settings, such as show run, which is the most basic troubleshooting command.However, the command cannot be executed when your user level is at 0-14. You can assign permissions to these users using the following command:Privilege EXEC level show Running-configWhen the configuration is complete, login level 14Router>enable 14
