The process in which IIS receives browser request packets and transfers the request packets to the asp.net framework (Basic edition ). Website pages are roughly divided into two types: I. Static pages Ii. Dynamic Pages The so-called Static Page and dynamic page are not differentiated based on the dynamic and static page content, but determined by the server's webpage processing method. Access an html

If you want to use the red packet you have received, go to the "pay" page of the water, electricity, and coal ", and divide the red packet and click" my Prize ";7. Click "use now" next to the red envelope. To reduce unnecessary troubles, read the rules before

between the protocol stack and the NIC, and if you are familiar with the IO process of the UNIX block device file, you can interpret the dispatch layer as a block device buffer. Block device According to Buffer's metadata solves the random IO and the first served problem that the data actually enters the medium, and the network card device relies on this packet dispatch layer to solve the traffic control problem.It is this middle layer that makes the NIC device more like a block device rather t

the simplest, but not much use, because basically can only see the information of the packet brush screen, can not see clearly, the use of CTRL + C interrupt exit, if there is a need, you can redirect the output to a file, so it is more convenient to view.Listens for data from a specified protocol$ tcpdump-i eth0-nn ' ICMP 'This is the data used to listen for the ICMP protocol, which is the protocol used by the ping command. Similarly, if you want to listen to TCP or UDP protocol, you just need

Colleagues directly open the Wireshark but captured take the WiFi interface, but found a bunch of Ethernet message box and heard the WiFi message box. Why? To see what Wireshark's official network says: If You ' re trying to capture network traffic, that's not being sent to or from the machine running wire Shark or tshark, i.e. traffic between, or more other

Conceptual Differences ET: Notifications are only available when there is a change in status. For example, data buffering goes from scratch (unreadable-readable), assuming that the buffer contains data, it will not be kept informed.

Currently, TCP/IP communication protocol and its standard socket application programming interface (API) are widely used in network transmission applications ). The TCP/IP transport layer has two parallel protocols: TCP and UDP. TCP (Transport Control Protocol) is connection-oriented and provides high-reliability services. User Data Protocol (UDP) is connectionless and provides efficient services. In practical engineering applications, the selection of reliability and efficiency depends on the a

What's the difference between the two?The conceptual differenceET: Only when the state changes, will be notified, such as the data buffer from scratch (unreadable-readable), if there is data in the buffer, it will not be kept informed;LT: As long as there is data in the buffer, it will be notified.Looked at a lot of information, the answer is nothing more like the above, but if you lo

Print all communication packets between the local host and the host on the Berkeley Network (Nt:ucb-ether, which is understood as the network address of the ' Berkeley Network '), the most original meaning of which is to print all packets with a network address of Ucb-ether Copy Code code as follows: tcpdump Net Ucb-ether Print all FTP packets thr

In the previous article, the Send-tcpmessage and receive-tcpmessage two functions were created in the Psnet toolset to implement the function of sending and receiving TCP message packets through PowerShell, with the TCP packet sent and received, Naturally without the sending and receiving of UDP message packets, this article will introduce the method of sending and receiving UDP message

The functions used to filter packets are pcap_compile () and Pcap_setfilter (). Pcap_complie () It compiles a high-level boolean filter expression into a low-level byte code that can be interpreted by the filtering engine. Pcap_setfilter () associates a filter with a kernel capture session. When Pcap_setfilter () is invoked, the filter is applied to all packets from the network, and all
