plan is implemented, he or she won the shugun plan, Hanzhong won the plan, and Ma Chao of Guanzhong, so it is said that the western region is Sun Quan, and the eastern region of Jiangdong is also Sun Quan. Liu Bei is truly a sandwich in it. What's more, we don't know if Zhou Yu will turn to the gun to deal with Liu Bei when attacking shugun in half, because Zhou Yu of Jiangdong Group insisted on killing Liu Bei.
Sun Quan approved the plan, and Zhou Yu went back to pack the pack, and went back t

Although the corruption penalty is painful, it is especially humiliating. Sima Qian committed suicide several times, but he finally lived in a cruel fate, in order to complete his "Historical Records" Masterpiece-this more than 0.5 million-character masterpiece, not only became a treasure of Chinese history, but also the documentary cut he created was regarded as a benchmark by future generations.
Here is a question: Why isn't Li Ling killed or killed like Han yannian?

Currently, root Cracking in Android is a basic skill! There are also a lot of software for one-key cracking on the Internet, making root cracking more and more easy. But you have thought about root cracking.How does it work? What is the essence of root cracking? Is it because of the Linux kernal vulnerability? This article will analyze the root cracking principle.
There is an article on the Internet that has briefly introduced the basic principle of root cracking. You can refer to "android root
Objectivealways curious about the fundamentals of Android Root, and just recently ran into a problem with the Android default with Root, and here's how the Android system root works.
PrincipleAndroid is an Open-source operating system based on the Llinux kernel, similar to the Ubuntu system, so getting root in Android is the same thing as getting root permissions on Linux. The way to get root permissions on a Linux system is to perform sudo or su at

After webbackdoor itself is root (potentially poor) or a vulnerability overflows to obtain the highest permissions, it can bring us many benefits if we can get the root password. I checked the methods of my predecessors. One is to cheat su to record the password, and the other is to replace sshd. Let's look at the code to cheat su to record the password!
First look at the first, kpr-fakesu.c V0.9beta167Fuck
Method One: Use Oracle's own startup and shutdown scripts1. Oracle User modified/etc/oratab file:
$ vi/etc/oratab
Orcl:/oracle/app/product/10.2.0/db_1:n
SwitchOrcl:/oracle/app/product/10.2.0/db_1:yThat is, change the last n to Y, allowing the Dbstart startup database to run at system startup.2. ORACLE User modified $oracle_home/bin/dbstart file:
# su-oracle
$ cd $ORACLE _home/bin
$ VI Dbstart
Find oracle_home_li
relatively high-end, there is a visual walkie talkie before entering the door, then you first call a friend through the walkie talkie (hitting adb shell ), check if you are not at home (whether the mobile phone has the adb shell Command). If your friend is at home, he will open the door for you through the walkie talkie (successfully accessing the mobile phone ), the visual walkie talkie that provides this service is equivalent to ADBD. To put it bluntly, ADBD can provide you with a service cha
Useradd: Add a user
Adduser: Add a user
Passwd: set a password for the user
Usermod: Modify user commands. You can use usermod to modify the login name, user's home directory, and so on.
Pwcov: Synchronize users from/etc/passwd to/etc/shadow
Pwck: pwck verifies whether the content of the user configuration file/etc/passwd and/etc/shadow is legal or complete.
Pwunconv: it is the vertical reverse operation of pwcov. It creates/etc/passwd from/etc/shadow and/etc/passwd, and

When you need to perform some administrator command operation, then switch to the root user to execute.The way a normal user switches to the root user is: Su and sudo.1 , Su-(

After the Webbackdoor itself is root (a little less likely) or is successfully given the highest privilege through a vulnerability overflow, it can bring us a lot of benefits if we can get the root password. Query the method of predecessors, one is to cheat SU record password
