海外TECH	DEV Community	Coding a Port Scanner with Python	https://dev.to/jsquared/coding-a-port-scanner-with-python-5he7	Coding a Port Scanner with PythonPort scanning is a way for determining which ports on a network device are open whether it s a server a router or a regular machine To simply put it a port scanner is just a script or a program that is designed to probe a host for open ports In this blog I will show you step by step how to code a simple port scanner using the pre installed socket library The idea of making the port scanner is to connect to a host it could be a website server or any device which is connected to a network internet through a list of ports If the scanner establishes a connection then that means the port is open DISCLAIMER THIS IS ONLY FOR EDUCATIONAL PURPOSES ONLY DO NOT USE THIS ON A HOST THAT YOU DO NOT HAVE PERMISSION TO TEST PORT SCANNING IS NOT ILLEGAL UNLESS IT IS USED TO GAIN UNAUTHORIZED ACCESS OR BREACH PRIVACY First things first if you want to print in colors you will need to install colorama this is completely optional pip install coloramaWith that out of the way now we can actually start coding the scanner First let s import the socket module import socket for connecting to the host from colorama import init Fore adding some colors optional init GREEN Fore GREENRESET Fore RESETGRAY Fore LIGHTBLACK EXThe socket module is a module already built in the Python standard library so you don t need to install it colorama is used later when the program prints the ports that are open or closed again this is optional Next let s create a function that will be used to decide whether a port is open or not def is port open host port determines whether the host has the port open creates a new socket s socket socket try tries to connect to host using that port s connect host port make a timeout if you want it a little faster means less accuracy s settimeout lt if you want to add a timeout except cannot connect port is closed and returns false return False else the connection is established port is open return Truethe s connect host port function attempts to connect the socket to a remote address using the host port tuple Tuples are used to store multiple items in a single variable it will bring up an exception when it fails to connect to the host so that is why we put that code into a try expcept block so when the exception is brought up it tells us that the port is closed otherwise it is open Lastly we can use the function we just made above and repeat it over a number of ports asks user to enter a port host input Enter the host repeat over ports from to for port in range if is port open host port print f GREEN host port is open RESET prints green text for open ports else print f GRAY host port is closed RESET end r prints gray text for closed ports This part of the code will scan all ports from to You can freely change the range if you so choose but keep in mind that if you increase the range it will take longer to complete scanning Potential IssuesUpon running the code you will notice that the script isn t the fastest You can change this by adding a timeout of milliseconds using settimeout Keep in mind that this will reduce the accuracy of the scanning especially if you have high latency If you want the full source code is on Github	2023-04-04 05:34:51
海外TECH	DEV Community	How to use .NET's built-in caching mechanism to improve the performance of your web applications	https://dev.to/bhavin9920/how-to-use-nets-built-in-caching-mechanism-to-improve-the-performance-of-your-web-applications-55o	How to use NET x s built in caching mechanism to improve the performance of your web applicationsCaching is a crucial technique for improving the performance of web applications By caching frequently accessed data in memory you can reduce the number of database queries and other expensive operations your application needs to perform leading to faster response times and better scalability In NET the caching mechanism is built into the framework making it easy to implement and customize Here are some tips for using NET s caching features to improve your application s performance Use the MemoryCache class NET s built in caching mechanism is based on the MemoryCache class which allows you to store data in memory for quick access To use the MemoryCache class you can create a new instance of it in your application and use the Add and Get methods to add and retrieve data from the cache respectively var cache MemoryCache Default var key myCachedData var data cache Get key as List lt MyData gt if data null If the data isn t in the cache query the database and store the results in the cache data db Query lt MyData gt SELECT FROM MyData ToList cache Add key data DateTimeOffset Now AddMinutes In this example we re using the MemoryCache class to cache the results of a database query for minutes If the data is already in the cache we retrieve it using the Get method If not we query the database and store the results in the cache using the Add method Use caching for expensive operations Caching is most effective when used for expensive operations that are performed frequently For example if you have a page that displays a list of products and the list rarely changes you could cache the product data to improve the page s performance Set a reasonable expiration time When you add data to the cache you can specify an expiration time to ensure that the data is automatically removed from the cache after a certain period It s important to set a reasonable expiration time based on how frequently the data changes and how important it is to have the most up to date information Monitor cache performance Like any performance optimization it s important to monitor the performance of your caching strategy to ensure that it s actually improving your application s performance You can use tools like PerfView to measure the impact of caching on your application s CPU and memory usage Caching is a powerful technique for improving the performance of web applications and NET s built in caching mechanism makes it easy to implement and customize By using caching for expensive operations and setting reasonable expiration times you can reduce the load on your database and other resources leading to faster response times and better scalability	2023-04-04 05:28:48
