Using tcpdump to capture mysql packets Using tcpdump to capture mysql packets is as follows: The command is as follows: Copy codeThe Code is as follows:Tcpdump-s 0-l-w-dst 192.168.244.10 and port 3306-I eno16777736 | strings -I indicates the network interface of the listener. in RHEL 7, the network interface name is no longer the previous eth0, but eno16777736. In RHEL 5 6, the-I parameter can be dire

The data and control information in each layer of the OSI Reference Model is transmitted in many formats, including frames, packets, datagrams, segments, messages, elements, and data units. The information exchange occurs between the peer OSI layers, where the control information is attached to the data at each layer of the source machine, and each layer of the destination machine is analyzed with the information received, and the control information

How does phpsocket receive multiple tcp packets in a row? you can read 16 bytes at a time, 4 times for 64 bytes. This is only the content of a tcp packet. where are the four packages? Tcp waits for the subsequent data before transmission until the buffer is slow or the data ends, and then sends the php socket to receive multiple tcp packets consecutively. How does php socket receive multiple tcp

Network data packets can be sent in three ways:Unicast, multicast, and broadcast. Generally speaking, broadcast enables the packets sent by your machine to be received by all hosts in the same network. Before explaining how to send broadcast packets, let's take a look at broadcast-related knowledge: We all know that IP addresses are used to locate a network int

Program. Ii. Initial settings of Sniffer Pro Sniffer Pro needs to capture packets, but too much information is captured. How can we start to filter when capturing? Set the following parameters: "capture"-"define filter"-"Address"-"Address type", and "location 1" to "10.66.1.188 ", enter "10.66.0.1" in "Location 2" and click "OK. 1. 　　 Figure 1 This is much simpler. We will define the filter so that we can freely use the Sniffer Pro software. Iii.

In XP, sendto is used to send more than 1500 data packets (the return value of sendto is normal), but recvfrom is not accepted. sniffer is used to find that the data packet has been successfully sent. So_rcvbuf, so_sndbuf, and so_max_msg_size of the monitoring program are default normal values. If you send packets smaller than 1500 on XP, everything works! The same program (data

With the rapid growth of HTML5, more and more people are involved in the Web development field of mobile terminals, but there are never so many debugging tools on mobile phones. Even if the PC browser simulates user-agent for development, rendering inconsistency may occur between the mobile terminal and PC browser. Therefore, it is best to develop and Debug on a real mobile phone, but how to capture packets? Today, we will introduce how Fiddler captur

The pitfalls for sending broadcast packets through Android SocketThe Socket broadcast package is often used for mutual discovery and message transmission between two devices in the LAN. During Android Application Development, such requirements are often met. For example: between Two Android devices, smart hardware such as Android and wristband, and between Android and Windows. This article mainly introduces the programming precautions when using Socke

In the past, when using Winpcap to capture packets from the NIC, only one Nic was captured. Now you have to capture multiple NICs as needed, because our previous device is a computer that connects to a device through a network card, there are now two user requirements, one is to attach two network cards on the computer, each network card is connected to a device, another requirement is to connect multiple devices through a network adapter on the PC th

How to Use Wireshark to capture data frames and IP data packets About WiresharkWireshark is one of the world's foremost network protocol analyzers, and is the standard in our parts of the industry.It is the continuation of a project that started in 1998. Hundreds of developers around the world have contributed to it, and it still under active development.Wireshark's powerful features make it the tool of choice for network troubleshooting, pro
