Python port scanning simple program, python port scanning This example shares the Python Port Scan implementation code for your reference. The details are as follows: Obtain the IP address and port number of the local machine: import socket def get_my_ip(): try: csock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) csock.connect(('8.8.8.8', 80)) (addr, port) = csock.getsockname() csock

The disadvantage is that recursive algorithms are used, which not only requires a large amount of stack space to store adjacent points, and the efficiency is not high. In order to reduce recursive calls in algorithms and reduce stack space usage, many impr

FromCSKLow-cost 3D compaction. Very impressive! Before introducing the principles, we will first give you some 3D models and demonstration videos after scanning, so as to give you an intuitive understanding.

Interlaced scanningEach frame is divided into two fields, each containing a frame of all the odd scan lines or even scan lines, usually first scan odd lines to get the first field, and then scan even rows to get the second field. Whether progressive or interlaced, there are three concepts for video files, transmission, and imaging, and these three concepts are interlinked but not identical. The first appearance is interlaced scanning, and the matching

NMap, also known as NetworkMapper, is a network scanning and sniffing toolkit in Linux. It has three basic functions: one is to detect whether a group of hosts are online, and the other is to scan host ports, network Service provided by sniffing; the operating system used by the host can also be inferred. Nmap can be used to scan networks with only two nodes and more than 500 nodes. Expert skills: nmap, a tool essential for Linux hackers 　[Special Rep

Port and vulnerability discovery and scanning are also necessary for enterprise risk assessment and management. As the saying goes: "The treasure of a thousand miles is destroyed by the ant nest ." Once an attacker finds a small vulnerability, the final consequence may be the paralysis of the entire network. How can we discover security vulnerabilities in enterprise networks? What key technologies need to be mastered and used? What popular and efficie

After learning about the features of various index scanning methods, you can determine whether the scanning methods used in your execution plan are correct, you can also make improvements to the o

Burp technique for non-Webapp testing (2): scanning and Replay In the first section of this series of serialization, I talked about the burp Function Testing for non-webapps. I only wanted to write something and share it with me. Now, I will continue writing.In this section, I will talk about:Target> ScopeProxy> HTTP HistoryIntruder/MixerAt the same time, I will talk about compaction, Repeater, and Comparer here, but I will not talk too much about it.

Q: On an infinitely large chessboard, the white child surrounded by horizontal and vertical nodes will become sunspots. How many sunspots will the final sunspots be solved? Analysis: First, this board is very big, but the number of black spots has been given to 1 E5. We need to discretization. The so-called discretization is the redefinition of the lower mark of the array. The discretization function is provided here, and the number of arrays after discretization is returned. 1 int compress(int

Server Q: If I need to run virus scanning software on a machine running SQL Server, what do I do without impacting performance? A: The answer to this question depends on the type of virus scanning software you want to run. There are currently three types of virus scanning software-active virus scanning, virus cleanup,

The software name Nmap is the abbreviation of Network Mapper. Nmap was originally created by Fyodor in 1997. Then, with the participation of many volunteers in the open source community, the tool is

Apart from IP detection, the hacker also has a port scan. Through port scanning, you can know which services and ports of the computer to be scanned are opened but not used (it can be understood as a channel to the computer ).I. Port Scanning It is easy to find remote port scanning tools on the Internet, such as Superscan, IP routing, Fluxay, etc. (1 ), this is t

You cannot protect things you don't know. Although this is not a mantra in the IT security field, when you look for security vulnerabilities from the perspective of "trusted" users, or in other words, perform a vulnerability scan through identity authentication, this principle is true. By configuring a vulnerability scanner to log on to the host you are testing, you will see the rest of the story-security aspects that are often ignored to save time or money, or because of complexity. The trut

[Original] Introduction to NMAP network port scanning tools I NMAP Introduction NMAP is a port scanning tool for large networks, although it is also suitable for single-host scanning. In different situations, you may need to hide, scan across the firewall, or use different protocols for scanning, such as UDP, TCP,
