Recently I am working on a scanning login function, so I also searched the internet for the implementation of scanning login. After this function is completed, I decided to sort out the entire implementation idea so that I can view it later and make it easier for other programs with similar requirements. We need to solve two problems to achieve scanning login: 1.

Instead of just reading a block of data, this greatly reduces the total
Currently, the main port scanning technologies include the following:1. TCP connect scan (TCP connection scan)This method is also called "TCP full connection scan ". It is the simplest scanning technology, and uses three handshakes of the TCP protocol. It connects directly to the target port and completes a complete three-way handshake (syn, SYN/ack, and ACK ). The CONNECT () function provided by the operat
Oracle index scanning is a common problem. The following section describes the types of Oracle index scanning for your reference.
There are four types of Oracle index scans, depending on the index type and where restriction conditions:
◆ Unique index scan)
◆ Index range scan)
◆ Full index scan)
◆ Index fast full scan)
(1) unique index scan)
A single ROWID is often returned for finding a value through a uniq

Scan is the basis for all intrusions. There are many host detection tools, such as the well-known NMAP. I don't have any new technologies here. They are old things and old things. Even if I have been referring to the phrack document or even a 96-year old document, I just picked people up.
The most basic test is Ping, but now even the

In this way, you can collect various information about the target host (for example, whether you can log on anonymously, if there is a writable FTP directory, w

Search method
This method primarily scans for specific strings that each virus contains, and if a particular byte string is found inside a detected object, it indicates that the virus represented by that byte string is found. The virus scanning software that works according to the search method is called "Scanner" abroad. This virus scanning software consists of two parts: part of this is the virus code ba

Efficient building algorithm based on the binary tree and Graham Scanning Technology
Abstract: In order to improve the construction speed of the irregular Triangle network, an efficient algorithm for building the Triangle network is proposed. First, the discrete point set on the plane is segmented according to a certain threshold value, and a sub-block index binary tree is established. Then, the Graham scan technology is used to construct a gridded
