HOSTAPD Introduction: Simply put, HOSTAPD can make the wireless card switch to master mode, analog AP (usually can be considered as a router) function, that is, we say the soft AP (Soft AP). The function of HOSTAPD is to be the AP's authentication server, which is responsible for the access and authentication of the management stations (which can usually be considered as a PC with a wireless network card). By HOSTAPD, the wireless network card can be switched to Ap/master mode, and an open (unen

pyramid matching (spatial Pyramid Matching) [6], the basic idea is to divide the image into a number of different sizes of windows, and then calculate the feature histogram of each window and pooled (Pooling) combination, At last, the weighted combination of different granularity is the final feature description, which is shown in 6.According to the experiment of [9], combining L2-norm, power-norm and pyramid matching, the results are shown in comparison with 7.References [1] Whitening tran

group members, thus implementing layer-2 multicast in the vlan. The switch periodically sends GMRP queries. If the host wants to stay in the multicast group, it will respond to GMRP queries. In this case, the switch does not perform any operations; if the host does not want to stay in the multicast group, it can send a leave message or not respond to periodic GMRP queries. Once the switch receives the host leave information or does not receive the response information during the time specified

The problem with this issue is that the tl-wr841n V8 version of the wired Nic down, then up, does not know what the specific reason is. But it will definitely cause problems during PPPoE dialing, dial failure, program hang.Here are some of the things I've modified about the order of wired ports, which may be problematic, but we need to address them carefully.?

Today, nothing is boring, write two blog to kill time ... This blog first introduces the basic principles of the UART, and then post my code. The UART is a serial data transmission format that sends and receives only one signal line for each use. It is often used in low-rate signal transmission, but it is necessary to change the transmission mode at high-speed data transmission, such as using Mac ETHERNET. To get to the point, first I UART the format of the data sent/received is: A starting bit

Hostapd introduction: To put it simply, hostapd can switch the wireless network adapter to the master mode and simulate the AP (which can be considered as a router) function, that is, the soft AP we call it ). As an AP authentication server, hostapd is responsible for controlling and managing the access and authentication of stations (usually a PC with a wireless network card. You can use hostapd to switch the wireless network adapter to the AP/master mode. By modifying the configuration file, y

This article was first published by IEEE software and is now presented to you by infoq and IEEE Computer Society. In software engineering, there is a close relationship between nonfunctional requirements and software architecture (SAS. As early as 1994, Rick kazman and Len bass affirmed that there was a close relationship between software architecture and non-functional requirements. 1. This idea has been p

At present, the application of WLAN has become an important means of high speed wireless data access in indoor community, especially in hot area. Many readers still have a smattering of wireless routing settings. This time we specially take a wireless router as an example, detailed introduction how to set up the router. Wireless routers in the market a wide variety of, but million change in which, as long as the reader extrapolate, no line by the setting nature can be easily. For broadband wi

The dynamic Wired Equivalent Security (WEP) model of IEEE 802.11 was designed in the late 1990s s, when the powerful wireless network encryption technology as an effective weapon was strictly restricted by the United States. Wireless Network products are banned from being exported due to fear of cracking powerful encryption algorithms. However, two

difficult to properly understand some basic knowledge. When you encounter difficulties or faults in use, you can solve them by yourself, not only saving time, but also learning a little knowledge. However, many people think that wireless routers can be used for plug-in! No need to set anything? Isn't it good? This is certainly the case for general applications, but if you encounter problems such as: Why is the overall suspension speed slow, and so on, will you be unable to start as a common con
