Description: 自己写的C# DOSS攻击实例 通过tcp 协议是3次握手的方式连接的，第一次客户机向服务器发送一个标志为syn的数据包，这个数据包的tcp部分有个16位随即序列号，而且ip部分和tcp部 分各有一个校验码，发送出去只有校验码正确才会视为合法的数据包，然后如果那个机器那个端口有服务器，比如http服务，就会把序列号+1，然后再生成一 个16位随机序列号，标志syn+ack的数据包返回，服务器就会占着一个信道等待第三次握手了，如果超过预定时间等不到就超时去掉了，这时如果开始那个 syn的源ip地址和源端口是伪造的并大量发送，服务器就会大量的向假ip端口返回syn+ack并等待，这样就大量占着信道了，如果超过了连接限制，别 的机器就连不上了，就拒绝服务了。原理大体就是这个样子了。-Write your own C# DOSS attack instance handshake connection through tcp protocol, the first time the client sends to the server a flag for the syn packet, this packet tcp part of a 16 then the serial number, and ip part and tcp part one on each check code sent only correct checksum will be regarded as the legitimate packets, and then if that machine that port server, such as http service serial number will+1, then regenerated into a 16-bit random serial number, logo syn+ack packet returns, the server will occupy a channel exceeds a predetermined time less than a timeout to remove the wait for the third handshake, then if you start the syn source ip address and the source port and send a large number of forged server will be a lot of to fake ip port to return syn+ack and waiting for, so that a large number of occupied channel, if the connection limit is exceeded, the other machines on the crawl denial of service. Principle roughly like this. Platform: |

Description: GY-53 是一款低成本数字红外测距传感器模块。
工作电压 3-5v，功耗小，体积小，安装方便。
其工作原理是，红外 LED 发光，照射到被测
物体后，返回光经过 MCU 接收，MCU 计算出
时间差，得到距离。直接输出距离值。
此模块，有两种方式读取数据，即
串口 UART（TTL 电平）+PWM（1 线）
或者芯片 IIC 模式，串口的波特率有9600bps 与
115200bps，可配置，有连续，询问输出两种方式，
可掉电保存设置。提供 arduino，51，stm32 单片机
通讯程序。，不提供原理图及内部单片机源码。
模块另外可以设置单独传感器芯片工作模式，
作为简单传感器模块，MCU 不参与数据处理工作。(GY-53 is a low cost digital infrared range sensor module.
Working voltage 3-5v, small power consumption, small volume, easy to install.
The principle of the work is that the infrared LED is illuminated and irradiated to be measured.
After the object, the return light is received by the MCU, and the MCU is calculated.
Time difference, get the distance. Direct output distance value.
This module, there are two ways to read the data, that is,
Serial UART (TTL level) +PWM (1 line)
Or chip IIC mode, the baud rate of the serial port has 9600bps and
115200bps, configurable, continuous, two ways of asking output,
Power saving settings. Provide Arduino, 51, STM32 Singlechip
Communication program. Do not provide the principle diagram and internal single chip source code.
The module can also set up the working mode of the individual sensor chip.
As a simple sensor module, MCU does not participate in data processing.) Platform: |
