The gateway is a kind of AC, manages the terminal equipment, the terminal equipment connects to the gateway through the wireless protocol such as Loura WiFi, the gateway device allocates the memory space to store the related device letter, then
would violate the law and be an immoral act. To build a wireless network platform in an experimental environment, Wireless AP is indispensable. In addition, three laptops with wireless NICs can also be used on desktops with wireless NICs) A simple network can meet the requirements. Figure 4 shows the network topology.

In the network shown in figure 4, we use a NETGEAR product named wgt624v2 for the selection
Access Point internal protocol and its implementation on the Access Point (1)
The IEEE 802.11 Protocol defines the specification and basic structure of the MAC layer and physical layer of the wireless LAN, but does not specify the construction of the wireless LAN. This leaves a lot of free space for the function design of the AP and its distributed system, but it also brings problems to the movement of the STA on the wireless site, this prevents Stas

Basic ConceptsRegistrar:an entity with the authority to issue and revoke Domain Credentials. A registrar may integrated to an AP, or it may be separate from the AP. A registrar May is not having A WLAN capability. A given Domain May has multiple Registrars. An entity that issues and r

We can come to the following conclusion:C. ADDR = B. ADDR + x_sizeof (B);/* Note: x_sizeof! = Sizeof. Let's talk about it later */B. ADDR = A. ADDR + x_sizeof ();
With the above "equation", we seem to be able to export the positions of variable parameters in the Void var_args_func (constchar * FMT,...) function. At least the position of the first variable parameter should be: first_vararg.addr =

Cracking WPA
Obtain the WPA handshake verification package
To facilitate the acquisition of WPA handshake verification packets, deauth authentication attacks must be performed to force the AP to re-perform handshake verification with

What does Wireless Access Point know about Wireless network AP? Do you want to know what types of wireless network APs are available? What is the difference between it and a wireless router? Read this article to solve these problems. Hope to help you. 1. Wireless Network AP and wireless route wireless network AP, that is, Access Point, that is, wireless Access Po
Few users may be familiar with WLAN switches. If you are interested, you can first understand the WLAN Network Architecture and access point functions, and then further understand the features and practical applications of WLAN switches. A wlan switch can connect to a WLAN Access Point (AP) through a wired connection (with a switch port ). They can also connect to the enterprise network through their other WLAN switch ports. These switches are the "ga
When we build a wireless network, WLAN switches are like a mainstay and cannot be ignored. Therefore, setting a vswitch quickly means that a WLAN Network is successfully created.
A wlan switch can connect to a WLAN Access Point (AP) through a wired connection (with a switch port ). They can also connect to the enterprise network through their other WLAN switch ports. These switches are the "gateways" connecting to the enterprise's wired network-all da
WLAN switches are quite common. So I studied the functions of WLAN switches and how to quickly implement the networking scheme. I would like to share with you here, hoping to help you. A wlan switch can connect to a WLAN Access Point (AP) through a wired connection (with a switch port ). They can also connect to the enterprise network through their other WLAN switch ports. These switches are the "gateways" connecting to the enterprise's wired network-
The application of wireless networks in the home can be easily configured successfully. However, a wider range of applications is used in office, and unlike traditional wired networks, wireless networks can be a hassle-relieving route and broadband connections anywhere in the company. First, the establishment and configuration of Access point Network An access point network is an access point that is similar to an Ethernet hub in a wireless network, and the wireless connection between computers

1. What is AP?
A: AP-WirelessAccessPoint AP is a HUB in a traditional wired network and the most common device used to build a small wireless LAN. AP is equivalent to a bridge connecting a wired network and a wireless network
capture file. We can change the default name, for example, change it to "capture" and then click OK, in this way, Kismet will start with capture as the file name, and then add the sequence number to save the captured packets to different files.
Figure 13: Specify the file storage location in kismet
When Kismet starts running, it will display all wireless LAN addresses it finds in this region, the content displayed in the "name" column is the SSID value of the
Look at the code first
Copy Code code as follows:
printf ("hello,world!"); The number of parameters is 1.
printf ("a=%d,b=%s,c=%c", a,b,c) with a number of 4 parameters.
How do I write variable parameter functions? Let's first look at how the printf function prototype is defined.
Under Linux, enter the man 3 printf, you can see the Prinf function prototype as follows:
Copy Code code as follows:
Synopsis
#include int printf (const char *format, ...);
1. Mixed wireless networks often fall off the line
Failure phenomenon
Use the Linksys WPC54G network card and Linksys WRT54G AP to build a wireless LAN that uses IEEE 802.11G protocols and a few 802.11B network adapters. The line is often dropped when using wrt54g for 54mb/s connections.
Fault analysis
In theory, the IEEE 802.11g protocol is backward-compatible with the 802.11B protocol, and devices using both protocols can be connected simultaneo

Although it is written as a variable parameter, how can the function determine the number and type of the subsequent real parameters? This requires such information to be carried in fixed parameters, such as printf (char *,...) The format string method used. The first parameter carries the numbe
This is an example program that uses variable function parameters, as shown below:# Include # Include # Include // # Include

that:C.ADDR = b.addr + x_sizeof (b); /* Note: x_sizeof!=sizeof */b.addr = a.addr + x_sizeof (a);With the "equation" above, it seems that we can deduce the position of the variable parameter in the void Var_args_func (const char * fmt, ...) function. At least the position of the first variable parameter should be: first_vararg.addr = fmt.addr + x_sizeof (FMT); Based on this conclusion, we try to implement a function that supports mutable parameters:#include #include void Var_args_func (const c
