packets sent to the host hostname: tcpdump-I eth0 dst host hostname # src indicates the source, that is, sending # dst indicates the destination, that is, receiving H. we can also monitor the data packets through the specified gateway: tcpdump-I eth0 gateway Gatewayname I. if you want to monitor the TCP or UDP data packets mapped to the specified port, run the following command: tcpdump-I eth0 host hostname and port 80 J. to obtain the telnet packet

How to Use tcpdump, a packet capture tool, and wireshark Tcpdump in Linux (1) the first type of keyword mainly includes host and net, port for example: host 210.27.48.2, specify 210.27.48.2 as a host. net 202.0.0.0 indicates that 202.0.0.0 is a network address, and port 23 indicates that the port number is 23. If no type is specified, the default type is host. (2) The second keyword determines the transmission direction mainly includes src, dst, dst o

1. IntroductionRefer to the Wireshark Development Guide, Chapter 2nd, "Quick Setup" for the relevant contents of this articleTo modify the Wireshark code, in addition to the following description of the LUA plug-in mode, you need to compile the Wirehshark source code (c external Parsing plug-in does not need to compile the entire wireshark, all need to download

-type:"HTTP contains "http/1.0 OK" http contains "Content-type:"Must contain the followingContent-type:Six, connector and/orSeven, expression:! (arp.src==192.168.1.1) and! (arp.dst.proto_ipv4==192.168.1.243)Wireshark matching rules are powerful.There is also a rule application that is about byte matching of the packet contents.For example:Match TCP Payload (actual data contents of TCP), first 6 bytes E3 11 00 00 00 48 (Electric Donkey Protocol)20 is

6 *tcp 17 *udp ...... There are 3 kinds of analytic tables in Wireshark, namely, String table, Integer table and heuristic parsing table. As shown in the following:The following is an example of an IP protocol that describes its registration process.The related important data structures and global variables are as follows.Proto.c/*Name hasht

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

Explore UDP socket programming and udp socket programming UDP and TCP are in the same layer network model, that is, the transport layer. There are many applications based on the two. Common TCP-based applications include HTTP and Telnet, UDP-based DNS, NFS, and SNMP are available.
