Recently in the socket transmission, encountered packet loss problem, troubled for a long time, saw this article, the original address: http://suwish.com/html/java-tcp-socket-stream-packet-split.html is good, now much easier. In other words, the official "empty track" animation schedule of falcom and the broken people are displayed. I mean it is really unacceptable. Of course, we can't handle this either.

Wireshark and TcpDump packet capture Analysis and Comparison
Common packet capture analysis tools include Microsoft's Network Monitor and Message Analyzer, Sniff, WSExplorer, SpyNet, iptools, WinNetCap, WinSock Expert, Wireshark, and linux tcpdump.
Today, we conducted an experimental test to compare and analyze two of them. Other users can use Baidu Google to test yiha ^_^.

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
I. Overview
Since the 1.1 kernel, Linux has already had the packet forwarding function. In the 2.0 kernel, we use ipfwadm to operate kernel packet forwarding rules. Later, in the 2.2 kernelYou are not familiar with ipchains to control the kernel package over the rules. Currently, the latest Linux kernel version is 2.4.1. In kernel 2.4, we no longer use ipchains,Use iptables, a new kernel package overhead m
For the TCP-based development of the communication program, there is a very important problem to be solved, that is, the package and unpacking. Let's talk about my thoughts on this question. If there is any wrong, the wrong place, begged everyone to correct. Thank you first.
I. Why TCP-based communication programs require packets and unpacking.
TCP is a "flow" protocol, the so-called flow, is a string of data without bounds. You can think of the river water, is connected into a piece, in the me

1. IntroductionThe so-called "underlying packet" refers to the "run" at the data link layer of the packet, simply said "Ethernet frame", and our common socket can only send "run" in the transport layer of TCP, UDP and other packets, these transport layer packets have been able to meet most of the demand, However, there are times when you need to send the underlying pack
Packaging and unpacking (Classic Collection)For the TCP-based development of the communication program, there is a very important problem to be solved, that is, the packet and unpacking. Since I've been working on network communication programming (about three years), I've been thinking about and improving the way that packets and unpacking are addressed. Here's what I think about this question. If it's wrong, The wrong place, begged everyone to corre

Abstract
Packet capture (interception) technology is mainly used in information security-related fields, especially firewall technology. With the development of the online game industry, m
During socket communication, we often encounter packet sticking problems! Nima has a high probability of frequent data increases.
Mina has considered this problem. cumulativeprotocoldecoder is answer!
Cumulativeprotocoldecoder class, a cumulative protocol decoder, that is, as long as there is data sent, this class will read the data and then accumulate it into the internal iobuffer, however, the specific package (decoding the data accumulated into
Recently, I was working on a project. Before that, I had a verification program.It was found that the client sent 1000 1024 bytes of packets consecutively, and the server experienced packet loss.The reason is that the server has not completely processed the data, and the client has sent and disabled the data.I used sleep (10) to solve this problem temporarily, but this is not a fundamental solution. If the data volume is large and the network conditio
understand the iso8583 standard in English, there are also similar behaviors on the Internet. We have translated the Chinese version of iso8583, so my goal is to learn about iso8583 after reading this article, so that people who have never been in touch with it can comply with the iso8583 packet specification.
Now, we should turn into the subject.

The destination IP address field contains a 32-bit binary value, representing the network layer address of the destination host of the data packet.
