When a user uses the Win7 system, some applications sometimes automatically connect to the network to get ads or pop-up windows in the Software window, while users can restrict these programs by using Third-party aids, but how can we mask the specified application connection network for users who do not use third-party assistive software frequently? ? Today Hedong software to firewall this powerful system f

Qt packet abstraction based on TCP network program I have no experience before. When sending data packets, the packet header and other information are all implemented by redefining a struct. Different protocol packages have different structs. The result is as follows: how many upper-layer business protocol packages are there? I will re-define a new structure corresponding to the ending of the packet header,

This article mainly introduces the example of a network program that implements ftp-like file transfer in python. if you need this code, you can refer to it and write it on linux. it is applicable to linux and windows, and several commands need to be changed. 1. enter the IP address and port of the client to connect to the server. the user name and password are required for verification. 2. use an independe

Some time ago, the virtual network card installation was required.ProgramSo in the website to collect some, find to find, did not see a separate installation, most of the said to install openvpn, and then only install the virtual network card of the tap-win32. In this case, the program of openvpnis used to run tapinstall.exe install oemwin2k. run the command line

These two years have been repeatedly to learn more about the TCP/IP protocol stack, but has always been on the surface, stop at the level of reading the textbook. Every time someone asks the TCP in-depth mechanism, there are many concepts in the brain that can not be clearly said. It's very stifling.This time hope can force themselves, the system to organize the network protocol, plans include several aspects:1 TCP/IP protocol collation, mainly TCP2 I

The specific methods are as follows: The example described in this article is a C/s applet written according to Wingide's prompts, the specific code is as follows: The client-side myclient.py code is as follows: #!/bin/env python #-*-coding:gb18030-*- # Import socket import time i=1
