I. TCP Scanning TechnologyThere are many common port scanning technologies, such as TCP connect () scanning, tcp syn scanning, tcp fin scanning, and many other articles on the network, for example, on the http://www.antai-genecon.com/suml/zhishiyy/jingong/duankougj.htm, I in

Custom QR code scanning open-source library ZXing and open-source zxing (Sorry, the article is still being modified but accidentally published =) I recently used the ZXing open-source library for QR code scanning. I would like to share with you some experience in code modification and cropping during the development process. My code library: Https://github.com/SickWorm/ZXingDialog The code is not maintained

Implementation Code of SignalR-based message pushing and QR code scanning logon, and signalr message pushing code 1. Summary I believe you will not be unfamiliar with the use of scan login. The combination of QR code and mobile phone has produced different application scenarios, and the application based on QR code is more extensive. To meet the needs of the combination of ios and android clients and web messaging platforms, A scan login Based on Sing

When we design a page or a banner, we tend to think about creativity, or make the results very dazzling, but ignore some user habits. What I'm talking about here is something that everyone knows, but is often easy to ignore-designed for scanning. Users are good at scanning and are diligent in scanning. WHY? 1. Busy-most users spend very little time reading a lot

When learning Oracle, you may encounter Oracle index scanning problems. Here we will introduce the solutions to Oracle index scanning problems. Here we will share with you. 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 retu

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

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.

Tags: style color ar os using for SP file dataThis article will introduce the methods of accessing the scanned data in Oracle.1) Full table scan (fully table Scans, FTS)For a full table scan, Oracle reads all rows in the table and checks to see if each row satisfies the where limit of the statement a multi-block read operation enables one I/O to read multiple blocks of data (db_block_multiblock_read_count parameter setting). Instead of just reading a block of data, this greatly reduces the total

Five steps for improving Authentication Vulnerability Scanning You cannot protect things you don't know. Although this is not an ITSecurityDomain mantra, but when you look for it from the perspective of "trusted" UsersSecurityVulnerabilitiesOr, in other words, perform authenticationVulnerabilitiesThis principle is true during scanning. By configuring a vulnerability scanner to log on to the host you are te

Introduction to advanced scanning technology and principles Release date:2002-01-29Abstract: Refdom (refdom@263.net) 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
