In Linux, It is very convenient to use tcpdump to capture packets, but Wireshark is more convenient to filter and analyze the captured packets.
The following describes how to use tcpdump.
Example: TCPDUMP host 172.16.29.40 and port 4600-X-S 500
Tcpdump adopts the command line method. Its command format is:Tcpdump [-adeflnnopqstvx] [-C quantity] [-F file name][-I network interface] [-r file name] [-s snaplen][-T type] [-W file name] [expression]

The following text is just a record of a small experiment I do, no code and procedures, no interest, please retreat.
In "Using Tcpmon to verify the security of Web Applications", it is said that HTTP is basically plaintext, if the use of sniffer to obtain HTTP packets, very much private information has been intercepted, the following will record this process.
The sniffer mentioned below is Wireshark, which is an excellent freeware software that you

Wireshark is a free network protocol detection program that supports Unix and Windows. It is a well-known free packet capture and protocol analysis tool. The Installation Method in Fedora 14 is simple:
Step 1: configure the yum source of the system;
Step 2: yum install wireshark
Step 3: yum install wireshark-gnome (install its graphical interface, which is slight
Use python to implement wireshark's follow tcp stream function
In short, wireshark has a follow tcp stream function, which is very convenient. The disadvantage is that the extracted stream data does not have any timestamp or other information, and it is insufficient to analyze the data delay and packet loss problems. Here, python is used to implement a simple follow tcp stream function while retaining tcp information.
The principle is very simple. It
In front, we played HTTP, quite a bit of meaning, in this article, we continue to play FTP (File Transfer Protocol). Both HTTP and FTP are application-layer protocols built on TCP, no matter how they are packaged, how they are loaded bigger, and ultimately TCP end-to-end transmission. This paper is divided into two parts: first. Use Wireshark to capture the content of FTP client GG and FTP server mm. Two. Use C code to briefly simulate the FTP client

Wireshark is a network packet analysis software. The function of the network packet analysis software is to obtain the network packet, and display the most detailed network packet information as far as possible. Wireshark uses WinPcap as an interface to exchange data messages directly with the network card. You can go to the official website to download the latest and stable version.HTTPS://www.wireshark.or
A while ago, need Wireshark grab bag, install good wireshark, but found that the login will always be stuck in the login interface,Stuck here, looking for a lot of days, finally found the problem.reason : The author of the computer installed is the WINDOWS10 system, but on the official web site Wireshark His default WinPcap version is 4.1.3, and this is not suita
We often catch a lot of data in Wireshark, and then we need to filter the filter to select the packets we care about.The Wireshark provides two types of filters:
Capture Filter: Set the filter condition before grabbing the packet, and then crawl only the qualifying packets.
Display filters: Sets the filter condition in the captured packet collection, hides the packets that you do not want to di
The first step must be to download the Wireshark software to the top of this machine first. After downloading, we put the installation package of this software on the C drive, and set the share for the C drive, and put the installation package on the top of the virtual machine.Explain how to set up sharing on this computer:For example, we share the E-drive settings:1. Right-click on "e-Disk" and select "Share":2, then step by step setup, after setting
When starting the Wireshark software, as shown in the error, the search for a solution, the following is summed up as follows:This error is caused by not opening the NPF service. Briefly say NPF.NPF , the network packet filter (Netgroup Packet FILTER,NPF) is a core part of WinPcap, and it is the component that WinPcap does difficult work. It processes packets that are transmitted over the network and provides capture (capture), send (injection), and a
