I really can't stand a CCIE teacher clicking the Wireshark packet capture item one by one to see the LS Type. You can skip this step when you see it. It is better to see my packet capture items. The teacher is a second knife. Build a topology at will. In order to obtain most of the LS types, re-distribute an OSPF to OSPF. The route table on R3 after full convergence R3 # sh ip ro1.0.0.0/32 is subnetted, 1 subnetsO E2 1.1.1.1 [110/20] via 172.16.1.1,

We use Wireshark to capture packets, but we do not know how to analyze these packets. We cannot extract the data we need from a large number of packages. The following describes the wireshark filtering rules. Filter source IP addresses and destination IP addresses. In the filter rule box of Wireshark, enter the filter conditions. For example, find the package w

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] 1. I

After Wireshark is installed in Ubuntu, the NIC information cannot be found during running. The reason is that my account is a common user and does not have the root permission. In this way, Wireshark does not have the permission to obtain the NIC parameters in a normal user's environment. The solution is to use sudo Wireshark in the terminal. For example:

, I thought I could find the download link of the video directly in the package that Youku returned.Pondering for a second, the heart felt that this method should be feasible, and then open the grab bag artifact Wireshark.At the same time, click on the Youku homepage to open a video and let it start playing. Wireshark soon appeared a lot of packages, I added the filter condition "http", let it crawl only the HTTP protocol related packets.The focus is

1. General analysisWhen Wireshark is started, all parsers are initialized and registered. The information to be registered includes the protocol name, the information for each field, the keyword to filter, the underlying protocol and port to associate with (handoff), and so on. In the parsing process, each parser is responsible for parsing its own protocol part, and then passing the upper package data to the subsequent protocol parser, thus constituti

E-mail is a service that we often use in our life and work to contact friends and customers all over the world. Below we will use Wireshark to grab the email packet.Preparatory work:Mail client section (Outlook,foxmail,koomail,...)Wiresharke-mail Test account twoMessage-Related Protocol knowledge (SMTP protocol, POP protocol, IMAP protocol)1.

It is very convenient to use tcpdump to grab the bag under Linux, but it is convenient to pick up the packet to extract it for analysis, or to use Wireshark to filter the analysis.Let's introduce the use of TCPDUMPExample: Tcpdump host 172.16.29.40 and Port 4600-x-S 500The tcpdump takes the command line, and its command format is:tcpdump [-ADEFLNNOPQSTVX] [-C Quantity] [-f filename][-I Network interface] [-R FileName] [-S Snaplen][-T type] [-w file na

To resolve the live video protocol on Android phones, you can capture packets to view existing live video applications, such as Phoenix TV and mobile TV. The main methods are as follows: 1. Install the live video application on the android simulation and capture packets using Wireshark to view what protocols are based on, such as RTSP/HTTP Advantage: in Windows, it is easier to use the wireshark packet ca

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
