infamous rootkit, due to its ability to hide and run programs efficiently. for more detail about the inner-workings of rootkits, please refer to my article"10 + things you shoshould know about rootkits." To become part of a botnet, you need to install remote access commands and control applications on the attacked computer. The application selected for this operation is the notorious rootkit because it can hide and effectively run programs. For more details about the internal work of rootkits,

spider class. I originally planned to write a batch download spider, but later I found that the implementation can be modified based on the original downloader class, so I directly changed the downloader class. This is the current example. BaseThe idea is that the scheduler generator will wait for the next parsing result after all URLs are generated, and then generate and return the parsing result. AddCall

Scrapy mainly has the following components:1, Engine (scrapy)Used to process the entire system's data flow, triggering transactions (framework core)2, Scheduler (Scheduler)Used to receive a request from the engine, pressed into the queue, and returned when the engine requests again, can be imagined as a URL (crawl web site URL or link) Priority queue, it determines the next crawl URL is what, while removing duplicate URLs3, Downloader (

So, the next goal of this open source project is to put the URL management in a centralized dispatch repository.The Engine asks the Scheduler for the next URLs to crawl.It's hard to understand what it's like to see a few other documents to understand. After the 1th, the engine from the spider to take the Web site after the package into a request, to the event loop, will be scheduler received to do scheduling management, for a moment to understand

information is to provide the downloaded file virtual into the equal size of the block , the block size must be 2k of the whole number of square (because it is a virtual block, the hard disk does not produce individual block files), and the index information of each block and hash verification code into the seed file; The seed file is the "index" of the downloaded file. To download the contents of the file, the download needs to get the appropriate seed file first.When downloading, the BT clien

Introduction Previously, I used scrapy to write some simple crawler programs. However, my demand is too simple. It is a little tricky to use scrapy, and the disadvantage is that it is too complicated to use, in addition, I do not like twisted very much. It is not natural to use Asynchronous frameworks implemented by various callbacks. A while ago, I came into contact with gevent.(I don't know why such a pure technical website will be in progress), not to mention that it is said to be of good per

1. The engine opens a domain, locates the spider that handles that domain, and asks the spider for the first URLsTo Crawl.2. The engine gets the first URLs to crawl from the spider and schedules them in the schedider, as requests.3. The engine asks the scheduler for the next URLs to crawl.4. The scheduler returns the next URLs to crawl to the engine and the engine sends them to the downloader,Passing through the d
