Principles of network sniffing tools sniffer wireshark
Today, I suddenly think of this question: the reason why wireshark can catch packets from other hosts is shared Ethernet. How can I use wireshark for switched Ethernet?
I read some documents online and sorted out the following article.
Sniffer is a common method for collecting useful data. The data can be user accounts and passwords, or commercial conf
Sniffing can only occur on a local area network where communication is addressed through a MAC address, which occurs over the LAN through IP addressing.ARP protocol, in computer A will send an ARP broadcast to find the communication object Computer B's MAC address, if there is a computer C, impersonate both sides of the IP, and send their own Mac to A and C, you can implement packet forwarding, and then imp

Now I have sokit and I basically don't use it anymore. This stuff is characterized by small size. 4. TCP/UDP socket debugging tool 2.3 In contrast, this tool has no features. Well, it does not even have an official homepage (a small advertisement is also included on the tool interface). I also recommend it, if you

1. IntroductionThe so-called "underlying packet" refers to the "run" at the data link layer of the packet, simply said "Ethernet frame", and our common socket can only send "run" in the transport layer of TCP, UDP and other packets, these transport layer packets have been able to meet most of the demand, However, there are times when you need to send the underlying pack
Protocol tables in the system. However, to successfully mount the dispatch function, you also need to mount the dispatch function in the ndis_open_block structure corresponding to the Protocol, because NDIS does not directly call the dispatch function address registered by the protocol driver in ndis_protocol_characteristics, rather it calls the dispatch function in ndis_open_block. It is worth noting that in DDK of Windows9x/ME/NT, the definition of ndis_protocol_block is clear, while in DDK o
We may encounter such a problem when preparing the computer's network connection. Using some network diagnostic tools provided by the Windows operating system, we can often find the crux of the problem to solve the problem. This article describes several practical network test commands in detail:

Iperf is a network performance testing tool. Iperf can test TCP and UDP bandwidth quality. The Iperf can measure the maximum TCP bandwidth with multiple parameters and UDP characteristics. Iperf can report bandwidth, delay jitter, and packet loss. Using Iperf, this feature can be used to test the performance of some network devices such as routers, firewalls, switches, and so on.There are two versions of Iperf, Wi

The tool even contains some simple debugging features that you can modify by setting
