First of all, I want to explain why I want to write this blog. I suddenly received an alert email from Nagios yesterday afternoon, saying that the number of processes on the mail server has exceeded the threshold. Therefore, log on to the system to view the information.The analysis process is as follows:1. Since the number of processes exceeds the threshold, you must first check the process: ps-ef;2. If the problem cannot be seen in real time, it will be displayed dynamically: top, to see which

Query set: merges connected cities into a set.
Sort: sort by traffic speed limit from small to large
Brute-force search: If a set has both the starting and ending positions, and the sorting is sorted from small to large, therefore, you can simply use the last put speed minus the first put speed. The Br
String matching is the key to database development and word processing software. Fortunately all modern programming languages and string library functions help us in our daily work. But it's important to understand their principles.String algorithms can be divided into several categories. String matching is one of them. When we refer to the string matching algorithm, the most basic method is the so-called brute force solution, which means that we need
If exists (select * From DBO. sysobjects where id = object_id (n' [DBO]. [p_getpassword] ') and objectproperty (ID, n' isprocedure') = 1)

Attackers can crack passwords with Chinese characters, special characters, characters, and trailing spaces.
For the convenience of displaying passwords with special characters, the displayed results show the ASCII

Finish writing the first string match article. Find out what is not actually introduced is the string matching algorithm. What is KMP, directly on the KMP next array is a bit abrupt. And when I'm going to write the second one, I find out why we have the KMP algorithm, where is it better than the normal algorithm? Look back and think about the common law of violence that should be written, so that the ability to clear their good. At the same time. Do not think it is a violent law to feel it is ba
excerpt from: http://linzhibin824.blog.163.com/blog/static/735577102013144223127/This brute force password cracking tool is quite powerful, supporting the online password cracking of almost all protocols, the key to whether the password can be cracked is whether the dictionary is strong enough. For social engineering infiltration, sometimes you can get a multiplier effect. This article only discusses the test from the security angle, uses the content

Nowadays, the Internet is very insecure. Many people use some scanners to scan the ssh port and try to connect to the ssh port for brute-force cracking (brute-force scanning). Therefore, we recommend that you use the vps host space, set a complex ssh logon password as much as possible, although I have introduced some time ago that Linux VPS prohibits an IP address from accessing the hosts. deny prohibits ac

No verification code is displayed on the logon interface; 3. No Logon error is found at the moment. There are two logon methods on the logon interface: Administrator and user (the difference is whether to select "Administrator Logon" when logging on "). Open burp and log on to th
The intruder module of burp suite is used to automatically detect Web applications. We can use it to brute force guess the user name and password. First, prepare the username and password dictionary. You can use the leaked username and password on the Internet, such as csdn, Tianya, and Renren. You can also use the dictionary tool to generate the dictionary. The super wood tool is still very useful.First, we caught the post package for logging on to t
