network pentesting

　　Network programming refers to writing programs that communicate with other computers. Java has encapsulated the things that a network program needs into different classes. Whenever you create objects of these classes, use the appropriate method.1. LAN and InternetTo enable communication between two computers, you must connect two computers with one network line

Overlay NetworkOverlay network is a new data format that encapsulates two beginning text over an IP message without altering the existing network infrastructure, through some kind of protocol communication.This will not only take full advantage of the mature IP routing protocol process data distribution, but also in the overlay technology, the use of extended isolated identity bits, can break the VLAN 4000

One NIC can choose different IP according to the network environmentSometimes we encounter a situation where, when participating in a company project, the network environment does not have a DHCP service, the IP configuration must be specified manually, and when we go home from work, we must change the IP configuration in order to properly surf the internet. In fact, both Windows and Linux support the confi

Win8.1 system The lower right corner of the network icon shows "unrecognized network" how to resolve First, dial-up Internet access Direct dial-up access to this fault, for the machine can not obtain IP address (broadband connection is using the PPPoE protocol connection extranet, the local connection is using the TCP/IP protocol.) The physical connection to the local connection is correct when dialing,

Due to recent business needs, a function to get all the IP in the network segment is written, as well as a function to allocate the available subnet segments/** * Calculate all IP * @param string $segment network segment ' 139.217.0.1/24 ' * @return array IP list [' 139.217.0.1 ', ' 139.217.0.2 ' ...] According to the network segment. */functionGetipbysegment ($s

The clone source's Centos7_1 network address is 192.168.140.11, and I want to change the network address of the cloned centos7_2 to 192.168.140.12. Two places need to be changed: The network configuration of the virtual machine and the Centos7_2 configuration file.If you don't know how to configure a static address, you can view the previous article:1. Configure

1, Network Division Local Area network: Small coverage, closed wide area network: distance, need to rent bandwidth Internet ISP: Self-built room, provide internet access Service 2. Computer Data communication Process Include IP address: Packet contains MAC address: Data frame 3. OSI Reference Model 3.1 Layered Model Application Layer: The program presenta

I. Introduction to the ConceptNetwork programs are divided into server-side programs and client programs. The service side is the one that provides the service, and the client is the party requesting the service. But the reality is that some programs of the client, server-side role is not so obvious, that is, mutual client and service side. When we write a network program, it is generally based on TCP protocol or UDP protocol for

Author: techrepublic.com.com Mike Mullins explains why you should change the network address of the network deployment. The following are some considerations. If the network you manage has enough IP addresses to cover hosts and servers, you may not need to configure network address translation (NAT ). Nat allows a sing

1. Read attack Read attacks mainly include all attacks related to information retrieval from victims. Such attacks scan ports and vulnerabilities within the IP address range of the organizational structure, and finally obtain information from vulnerable hosts. 1. Reconnaissance recon Attacks: Reconnaissance recon attacks: these attacks are designed to enable attackers to obtain more information about victims. They can use active and passive methods, in almost all cases, successful reconnaiss

This article analyzes kernel-based Linux Kernel 1.2.13Original works, reproduced please mark http://blog.csdn.net/yming0221/article/details/7488828See column, Address http://blog.csdn.net/column/details/linux-kernel-net.htmlShumingThe next series of posts will delve into the Linux kernel's network stack implementation principle, see Dr Cao Guiping's analysis, also decided to choose the Linux kernel 1.2.13 version for analysis.The reasons are as follow

The following are the reasons and solutions for the slow speed of the network: First, the network itself problem The destination Web site you want to connect to is on a server with insufficient bandwidth or too much load. The processing method is very simple, please change the time period to go up again or change a target website. Second, network cable problem

I. WedgeNow that you've learned to write Python code, if you've written two Python files a.py and b.py and run them separately, you'll find that the two Python files work well. But what do you do if you want to pass a data between the two programs?This problem can be solved with your knowledge now, we can create a file, write the content that a.py want to pass to the file, and then b.py to read the content from this file.But what do you do when your a.py and b.py are on separate computers?Simila

Toll Data Network 4G Network You can use the communications company 4G Network, you should pay attention to the use of data network is charged. Note 4G network usage charges Please note that the use of 4G

1. We want to turn off the 4G network simply click "Apps" on the phone's desktop.2. Furthermore, we find the inside "set" entry.3. Then we find the inside "More network" click to enter.4. Furthermore, we click on "More Network"-> "mobile network" and then enter. 5. Then after opening the interface "

In the command line in the multi-network management is a special demand from me, but for a variety of reasons, do not want to change back to network that old way to manage the network. Let's talk about this particular need: Run Ubuntu (virtual machine) in your notebook, with a Web site project, because both in the office and at home can be simultaneously through

First, check the network cable We open "Control Panel" in the computer and we find "network and Internet" in the control Panel we found, check whether "Wlan" or "Ethernet" are connected, as shown in the following figure. Ii. Retrieve IP address information Let's see if it's an IP problem we can press (WIN+X) and then enter Ipconfig in the pop-up interface to view it. Let's see if

Internet cafe sniffing With the development of multiple levels and diversity of the Internet, Internet cafes have been used in simple applications such as instant messaging, Web browsing, and email, extended into technical applications that run a large number of online games, online video and audio, interactive teaching, and P2P. Application features also present diversity and complexity. Therefore, these applications impose more stringent and demanding requirements on the quality of our
