During iOS development, various network access problems often occur. In the past, packet capture tools were not used, and many network problems were solved. Now, we have finished. This article provides two methods for packet capture: 1.Network Sharing +Visual packet capture tool Basic Principles The principle is relatively simple. iOS devices share the wirele

Application layer packet capture solution and implementation Author: Fang Introduction Packet Capture needs generally come from filtering, conversion protocol, and packet capture analysis.Filters have many applications, typically packet filter firewall.The application of the conversion protocol is limited to some specific environments. For example, if a thi

Thoughts on Exception Handling Java has two types of exceptions. I. Check exceptions. Ii. Non-checkable exceptions (runtime exceptions) The difference between the two: Check exceptions must be explicitly try-catch or throw. You do not need to capture runtime exceptions. There is no need for much discussion about checked exceptions because they must be captured (during design exceptions ). This article mainly discusses how to throw and

Internet Explorer 5.5: div-> body-> document Internet Explorer 6.0: div-> body-> HTML-> document Mozilla 1.0: div-> body-> HTML-> document-> window (2) event capturing: events are triggered starting from the most inaccurate object (Document Object), and then to the most precise (events can also be captur

Objective DirectShow is a Microsoft-provided development package for streaming media processing on Windows platforms, published with the DirectX development package. DirectShow provides a powerful support for capturing and playback of multimedia streaming. Using DirectShow to develop the application, we can easily capture data from the acquisition card that supports the WDM drive model, and do the corresponding post-processing and even store it in th

The event flow describes the order in which events are received from the page. It is IE and Netscape that bring up the concept of the event flow, but the former is a common event bubbling stream, and the latter is the event capture stream. The first part: event bubbling That is, the event begins to be received by the most specific element, and then propagates up to the less specific node (document). Here's a simple example: At this point,

Fscapture is a screen capture tool that comes with two other small features: a color filter and a screen magnifier. Allows you to scale, rotate, subtract, and adjust the color of captured images. With just a few clicks, you can capture anything on the screen. Drag and Drop support can directly Import images from the system, browser or other programs.Color FilterNow there should be a lot of color collectors

Oh, look also carefully, yes, we can not worry about it, and someone asked, you did not write about the delegation of the detailed introduction, oh, it seems that my fans know a lot, but this introduction focus on different, nonsense less, into the theme is the truth.The delegate of c#1.0We know it today. A list can be implemented by lamda such as where or predicate, whereas in c#1.0 we have to write a method to implement the predicate logi

In centos, when we need to capture network packet analysis, we usually use tcpdump to capture the network raw packet and save it to a file, and then download it to the local machine to use the wireshark interface network analysis tool for network packet analysis. Recently, wireshark also provided the Linux command line tool tshark. Tshark not only supports packet captur
