C # Raw Socket for network packet monitoring, Compared with Winsock1, Winsock2 supports the Raw Socket type most obviously. Using Raw Socket, you can set the NIC to the hybrid mode. In this mode, we can receive the IP packet on the network, of course, for the purpose of not the local IP

When talking about socket programming, you may think of QQ and IE. That's right. Many other network tools, such as P2P and NetMeeting, are implemented at the application layer using socket. Socket is a network programming interface that is implemented on the network application layer. Windows Socket includes a set of system components that fully utilize the featu

select the Include column, select Add an item, and then fill in the protocol, host address, port number you want to monitor. This allows you to intercept only the packets of the target Web site. As shown in the following: Typically, we use Method 1 to do some temporary packet filtering, using method 2 to do some frequent packet filtering.Intercept network p

Packet Tracer Introductory One, hub overview The received signal is amplified by reproducing and shaping to enlarge the transmission distance of the network, and all nodes are concentrated on the node which is centered on it. Work at the bottom (physical layer) of the OSI (open System Interconnect Reference Model).II, Hub classification Passive hubs: No processing of signals, no expan

1 Introduction to Analog delay transmission Netem and Tc:netem are a network emulation module provided by the Linux kernel version 2.6 and above. This function module can be used to simulate complex Internet transmission performance in a well performing LAN, such as low bandwidth, transmission delay, packet loss, and so on. Many distributions Linux that use the Linux 2.6 (or above) version of the kernel fea

Filtering Network RequestsTypically, we need to filter the network requests and only monitor requests sent to the specified directory server. We have 2 ways to do this. Fill in the filter bar in the middle of the main interface with keywords that need to be filtered out. For example, our server's address is: http://yu

Recently on the million Gigabit network card test, there has been a phenomenon that the Gigabit network card did not appear, Tasklet version of the netback, the VM to carry out the package test, found that vif interrupt default binding on CPU0, but the VM packet run found on the host CPU1, The ksoftirqd of CPU2 is very high.From the previous understanding, the pa

. Listener principles Ethernet, a popular LAN technology invented by Xerox, contains a cable from which all computers are connected, each computer needs a hardware called an interface board to connect to Ethernet. The protocol works by sending packets to all connected hosts. The packet header contains the correct address of the host that should receive data packets, because only the host with the same destination address in the data

Previously, we talked about libpcap packet capture, especially in the case of a gigabit network, which results in a large number of packet loss and a long time of searching on the Internet. This is probably a method like PF_PACKET + MMAP, NAPI, and PF_RING, I tested PF_RING + libpcap and found that the packet capture p

One day, an internet cafe user called our telecom operator to report a fault and asked us to solve the problem. The reason was that the technical staff of the Internet cafe Network Administrator analyzed that the fault was definitely caused by the telecom terminal. After receiving an obstacle message, I checked the information of this Internet cafe and found that the Internet cafe had just been opened for less than a month. So I asked him first: What
