The advantage of using native is that the scanning is particularly fast and efficient, using avfoundation to scan the QR code, and the main limitation is to limit the size of the scanned QR code.

Python pyramid exchange QQ group: 220128626. welcome to join. Because it is a casual record of the results of thinking and learning at ordinary times, it is relatively trivial and the format will not be done. If you want to write a learning record or something in the future, the format will be better. ^_^ Cause: Follow the official beginner's tutorial to learn about pyramid and use the pcreate-s starter myproject command to generate a project. To debug the project, modify myproject/_ init _. p
0x01 WMAP IntroductionWMAP itself is not a separate vulnerability scanner, but as a module of Metasploit, combined with web vulnerabilities and Web services related modules work together to complete the target Server Scan task, that is, If we want to use the WMAP module, we need to load it in Metasploit to be able to use it.0x02 Metasploit Database Preparationthe new version of the Metasploit database connection method is different than the old versio
Sqlmap can batch scan the log file containing request, and the request log file can be obtained by burpsuite.As a result, the Sqlmap combined with the Burpsuite tool allows for a more efficient, carpet-based scan of the application for SQL injection vulnerabilities.The scanning method usually has two kinds of Windows scan and Linux scan.One, under Windows
Whenever I infiltrate the Intranet to face a large number of hosts and services, I am always accustomed to using automated methods to extract information from the NMAP scan results. This facilitates automated detection of different types of services, such as path blasting of Web services, testing of keys or protocols used by the SSL/TLS service, and other targeted testing. I also often use Ipthon or *nix shells in penetration testing, which can be a
Each node in various IP-PUBLIC-VIP-Private-scan ip 1, PUBLIC, and VIPOracle RAC in RAC has a virtual IP address (VIP), which is in the same network segment as the public ip. The vip is attached to the public network interface. The main difference between VIP and public ip is that VIP is floating while public ip is fixed. When all nodes are running normally, the VIP address of each node is allocated to the public NIC. In the ifconfig command in linux,
NMap, also known as Network Mapper, is a web scan and sniffer toolkit under Linux.Nmap is a powerful scanner that is often used in network safety penetration testing. The power of function is self-evident. Here are some of its scanning commands. Specifically, we have to rely on everyone to learn, because it is too strong.1) Get the system type and open port of the remote hostNmap-ss-p0-sv-o Here the -ss TCP SYN Sc
1. Low Efficiency of fuzzy search: Cause: like itself is relatively inefficient. You should try to avoid using like in query conditions; for like '%... % '(Full fuzzy) is a condition where indexes cannot be used. Full table scanning is very inefficient. In addition, because of the matching algorithm, the length of the fuzzy query field is larger, fuzzy query efficiency is lower. Solution: Avoid fuzzy queries as much as possible. If fuzzy queries are required for services, do not use full fuzzy q

Preface: In most cases, a table scan or index scan is not an efficient way to return a small amount of data, especially from a large table. These must be found and resolved to improve performance because the scan traverses each row, finds the eligible data, and returns the results. This kind of processing is quite time-consuming and resource-consuming. In the pe

How to Use ClamAV to scan viruses? ClamAV Introduction Many viruses are not generated for Linux distributions. Because of this, most people who use such systems have never thought of using anti-virus software. However, some people do want to scan their systems or other Windows-based systems that connect to a Linux PC over a network, so they can use ClamAV. ClamAV is an open-source Anti-Virus engine designed
