packet tracer network

Compared with WINSOCK1, Winsock2 most obvious is to support the raw socket socket type, using raw socket, can set the network card into promiscuous mode, in this mode, we can receive IP packets on the network, of course, including the destination is not the local IP packet,Through the original socket, we can also more freely control the various protocols under Wi

What is NetBee?NetBee is a new library intended for several types of packet processing, such as packet sniffing and filtering, packet Dec Oding, and traffic classification (not ready yet).NetBee provides a set of modules that can is used by applications the need to process network packets. Instead of creating some cust

Chengdu Neusoft Information Technology Vocational College (Level 04) Apply layer network packet capture using Hook Technology Class: Class 2 of Visual ProgrammingINSTRUCTOR: Li DanStudent ID: 04311110210 Name: Liu Haiping Abstract Packet capture (interception) technology is mainly used in information security-related fields, especially firewall technology.

Article title: Network System Management-application layer packet capture solution and implementation. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 　　 Introduction Packet capture needs generally come from filtering, convers

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

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

According to the WOL protocol, when the computer is turned off and the NIC is powered, the WOL Magic Packet received from the network will be automatically powered on. This approach can be easily used in environments where remote administration is required. This program realizes the network wake-up Magic packet sending

Packaging and unpacking (Classic Collection)For the TCP-based development of the communication program, there is a very important problem to be solved, that is, the packet and unpacking. Since I've been working on network communication programming (about three years), I've been thinking about and improving the way that packets and unpacking are addressed. Here's what I think about this question. If it's wro

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

vswitch, connect one by one, and check whether the connection is normal until the connection is interrupted. Then we can determine which network cable is faulty, find the problematic host through the network cable. . Virus detection and removal can generally solve the problem. However, we can see that this workload is very large. If there are enough switches and there are more than one faulty computer, it

Programming | network Talking about socket programming, we may think of QQ and IE, yes. There are many network tools such as Peer-to-peer, NetMeeting and other applications implemented in the application layer, but also with the socket to achieve. The socket is a network programming interface that is implemented at the networ
