0. Write in frontFor the first contact with the Linux system, the installation of ns-3 seems unfriendly. But in fact, the installation process is not as complicated as it seems to be in a methodical way. In this paper, the installation process in the official Wiki is slightly combed, hoping to bring some convenience for beginners. As the description in the official Wiki is sufficiently detailed, there will

Now many friends have their own blog page, although they may not want to go to the wood to write a personal diary of the way, but to highlight the personality, publicity of the purpose of the ego, mostly similar. In fact, at this time, many of China's technology fans have looked to the wiki. After the network anti-Huang and Miko Mi, China's netizens have been familiar with the blog. As a new network concept, with the support of sophisticated technolog

Python crawler BeautifulSoup recursive fetch instance detailed Profile: The main purpose of crawlers is to crawl the content that is needed along the network. The essence of them is a recursive process. They first need to get the content of the page, then analyze the page content and find another URL, and then get the page content of the URL, repeating this process. Let's take Wikipedia as an example. We want to extract all the links from the Kevin Bacon entry in Wikipedia to other terms. #-*-C

This article mainly introduces detailed information about the Python crawler package BeautifulSoup recursive crawling instance. For more information, see The Python crawler package BeautifulSoup recursive crawling instance. Summary: Crawlers primarily aim to crawl the desired content along the network. They are essentially a recursive process. They first need to obtain the content of the webpage, analyze the content of the page, find another URL, and then obtain the page content of the URL, and

Moinmoin1.8.3 is finally installed. Write down the steps for future use. Since apache2, Python, and moinmoin are not understood, they are all rigid steps: 1. Open the terminal and switch to the administrator privilege. Sudo-I 2. Install apache2 Apt-Get install apache2 3. Download moinmoin1.8.3 Official Website 4. Decompress moinmoin 1.8.3 tar.gz to a directory where/opt/moinmoin-1.8.3 is used. See the/opt/moinmoin-1.8.3/docs/install.html document before installation. 5. Install the/opt/moinmoin-

Preface The previous two articles talk about project management tools at the code level. This article will introduce the knowledge management tools, which are also part of project management. When it comes to knowledge management, what do you think? Woven network? Find a node? Yes, this is personal knowledge management. What about a project or an enterprise? How should enterprises build networks and find nodes. You must have heard of the word wiki. Co

file Backup092210.sql, you can perform the following command: 　　 %>mysqldump-u root-p--all-databases > Backup092210.sql Enter Password: Here, in order to be able to access all databases, we need a root permission, so here we need to enter the corresponding password after the prompt. Also, if you are practicing these commands on a development server, take some time to look at the contents of the backup file. You'll see a series of SQL statements, first the statements that were recreated

Find the "Wikipedia six-degree separation theory" method. That is to say, we are going to implement from the Edgar · Edel's entry page (Https://en.wikipedia.org/wiki/Eric_Idle) starts with a minimum number of link clicks to find Kevin · Bacon's entry page (Https://en.wikipedia.org/wiki/Kevin_Bacon).You should already know how to write a Python code that gets any page from the Wikipedia site and extracts the

This article introduces some of the principles in software design, which are learned after long-term experience. Every programmer should understand them. I believe it will be of great help to everyone in the process of software design. Don't repeat yourself (dry)Dry is the simplest rule and the easiest to understand. But it may also be the most difficult to be applied (because to do so, we need to make considerable efforts in generic design, which is not an easy task ). It means that when we di

, it must be immune and provide powerful blocking measures to protect network users, all defense measures should be implemented based on hardware. However, all security measures are based on known attack methods and security vulnerabilities. If we cannot monitor the entire network, security will not be a complete feature ., Taking into account the high-speed forwarding of 10-ge switches and routes, the previous method of collecting traffic by CPU will not work, and the integrated distributed tra

Similar to top monitoring system activity, ntop is a tool used to monitor network usage in real time. Because ntop has the Web interface mode, it is easy to get started quickly in a short time, regardless of configuration or usage. Nbsp; this version partially overwrites the ntop processing engine, mainly used Similar to top monitoring system activity, ntop is a tool used to monitor network usage in real time. Because ntop has the Web interface mode, it is easy to get started quickly in a shor

Technology Software Defined monitoring (SDM ). In SDM, SDN switches act as data packet analysis devices, while controllers act as monitoring and analysis devices. Use SDN to monitor security and analyze data packets First, cheaper consumer programmable SDN switches from vendors such as IBM, Juniper, HP, and Arista Networks can be used to replace expensive data packet analysis devices. Similar to Microsoft's use cases, a large number of personal connections and data streams are aggregated and se

OpenvSwitch enables interconnection between Docker containers and hosts 1. Introduction to OpenvSwitch Open vSwitch (OVS) is a virtual switch dominated by Nicira Networks that runs on a virtualization platform (such as KVM and Xen. On the virtualization platform, OVS can provide a layer-2 switching function for dynamically changing endpoints to control access policies, network isolation, and traffic monitoring in virtual networks. The main implementation code is the portable C code. It aims to e

The only available real segment control is the local Virtual LAN (VLAN) Tag.With the Windows 8 vswitch, Microsoft has extended a set of APIs and drivers, which simplifies Virtual Devices of network security vendors and allows them to create Virtual Switch Extensions ), www.2cto.com naturally integrates Hyper-V.
