In front-end development often encounter a series of compatibility issues, how to accurately identify the version of each browser is a headache, especially navigator may be forged by the manufacturer. While the great gods recommend that you work with browser features rather than through browser versions, there are considerable difficulties in the actual operation.Here are the various browser sniffing methods that the great gods have summed up.IE article:ie=!!

PHP Port Sniffer--you can specify Web sites and Ports and return to the sniff results function Http_request ($server, $port) { $data = ""; $query = "head/http/1.0"; $fp = Fsockopen ($server, $port); if ($fp) { Fputs ($FP, $query.

ColorSoft (formerly Anti ARP Sniffer ). The biggest feature of the software is that the system kernel layer intercepts false ARP packets and proactively notifies the gateway of the correct MAC address of the Local Machine. This ensures that the computer where the software is installed can access the Internet normally, it also intercepts external ARP attacks on the local machine. If an internal ARP attack is detected, the attacker can directly process

Nmap Concept NMap, also known as Network Mapper, is the first web scan and sniffer toolkit under Linux. Nmap is a network-side scanning software used to scan Internet computers open Network connections. Determine which services are running on which connections, and infer which operating system the computer is running (this is also known as fingerprinting). It is one of the required software for network administrators and is used to evaluate network sy

20-53-52-43-00-02. Now machine A has updated its ARP cache, I believe that the MAC address of the machine whose IP address is 10.0.0.3 is 20-53-52-43-00-02. When machine A sends an FTP command -- ftp10.0.0.3, the data packet is sent to the Switch. The Switch checks the destination address in the data packet and finds that the MAC address is 20-53-52-43-00-02, so he sent the

Wireshark is a very useful packet capture tool. When we encounter network-related problems, we can use this tool for analysis. However, it should be noted that this is just a tool, the usage is very flexible, so the content described today may not help you solve the problem directly, but as long as you have the idea of solving the problem, learning to use this software is very useful.Wireshark http://www.wireshark.org/download.html officialIf you cann

Grouping starts from a single host (source), transmits through a series of routers, and ends its journey in another host (destination). When grouping from a node (host or router) along this path to a successor node (host or router), the packet undergoes several different types of latency at each node along the way. The most important of these delays are node processing delay (nodal processing delay), queue delay (queuing delay), transmission delay (tr
