浅谈僵尸网络利器：Fast-flux技术 一、背景 在早期的僵尸网络中，控制者通常会把C&C服务器的域名或者IP地址硬编码到恶意程序中，僵尸主机通过这些信息定时访问C&C主机获取命令。但同时安全人员也能够通过逆向恶意程序，得到C&C服务器的域名或者IP，利用这些信息定位C&C主机，安全人员就可以隔断C&C主机从而破坏僵尸网络。不少控制者为了保护C&C主机，使用Fast-flux技术来提高C&C服务器的健壮性。 二、基本概念 在正常的DNS服务器中，用户对同一个域名做DNS查询，在较长的一段时间内，无论查询多少次返回的结果基本上是不会改变的。Fast-flux技术是指不断改变域名和IP地址映射关系的一种技术，也就是说在短时间内查询使用Fast-flux技术部署的域名，会得到不同的结果。图2-1为Fast-flux技术工作方式。 图2-1 客户端访问Fast-flux网络流程 客户端两次访问 www.example.com 的过程如下： 1) 为了得到网站 www.example.com 的IP地址，客户端发起DNS查询。 2) 随后DNS服务器返回了一个IP地址1.2.3.4，同时TTL为一个很小的数值。 3) 客户端访问IP为1.2.3.4的服务器获取内容。 4) IP为1.2.3.4的服务器响应请求，返回相应内容。 5) 客户端再次访问 www.example.com

How can I update redux's state from a text input? I'm trying to do a very simple "Hello World" with a text input. When someone types into the text input, it should update my store's "searchTerm" value. I can't figure out these things: 1. How can I get and pass the input's value into it's "onChange" handler? 2. The "search" action seems to be called correctly, but my reducer function is never used (no console.log). SearchForm.js (component) import React, {Component, PropTypes} from 'react'; import {bindActionCreators} from 'redux'; import {connect} from 'react-redux'; import {search} from

I've got a web service that I'm trying to consume with the new Spring 5 WebClient. Working example # GET /orders/ [ { orderId: 1, ... }, { orderId: 1, ... } ] And the java code for the call // Java Flux<Order> ordersStream = webClient.get() .uri("/orders/") .exchange() .flatMap(response -> response.bodyToFlux(Order.class)); Problem The response from the web service is paginated and therefore doesn't contain the list of items directly as in the example above. It looks like this # GET /orders/ { "error": null, "metadata": { "total": 998, "limit": 1000, "offset": 0 }, "data": [ { orderId: 1, ...

I build an app with pure React. Its primary page shows multiple movies (user added). Users can vote and comment on every movie listed. I have a MovieCard component, which is responsible for a single movie. Then in Home I render an array of MovieCard components. Next I decided to implement a call to foreign movie database API, to get relevant movie information. It worked fine. Then I decided to refactor it in Flux pattern, using Alt and following the guidelines of this tutorial. Everything worked well, until I got the the MovieCard . In there, inside componentDidMount I call the action, which

前言 一直在思考部署应用到k8s的姿势，之前介绍过helm，个人感觉helm把记 录数据放到k8s中不是特别好。最近发现了weave的 flux 项目(A tool for deploying container images to Kubernetes services)。 flux简介和注意事项 flux简介 先上图，大致看一下flux的理念。 1：flux可以和任意你喜欢的CI工具搭配比如：Drone,CircleCI,gitlabCI等。实际上flux做了CD的环节。 2：flux可以帮助你安全地更新应用。一般会遇到更新过程出错的问题，在flux实现中， 每个部署的应用的yaml文件存储在git仓库里 ，所以每次更改都可以追踪，所以也能精确回滚到任何一个历史版本。这点我是觉得非常好的。当应用需要更新镜像的时候，有以下几个步骤： Clone the repository Find the deployment files that use the image in question (there may be more than one, since we have e.g., sidecar containers that use the same image) Update a few fields in each file, in slightly different

I know this question has been asked more times in different flavours, but I didn’t find the "right" answer yet (maybe there just isn't one), so I’m looking for the "most Flux" one. Simple example: two components - LoginForm and Information user has to provide his/hers login information, submit the form and only after that he/she has right to "ask" for the information (this should be done automatically after login) Project structure along these lines: + actions |-- LoginAction |-- InfoAction + api |-- API + components |-- LoginForm |-- Information + stores |-- LoginStore |-- InfoStore Options:
