How to write a program with c that automatically captures ARP packets?

arp packages can be used in ms's platformsdk in ip helper dword sendarp (ipaddr destip, ipaddr srcip, pulong pmacaddr, pulong phyaddrlen);

To send, it's easy to implement in c, I haven't tried it in c, you can try it, there is an example of vc in the link msdn, I don't know if my statement is right, dllimport("",charset=public extern static sendarp( destip,srcip,out pmacaddr,out phyaddrlen);

Please refer to the development in C, but to call a sharpcap source** is also provided.

It's just that it's a piece of software that sends ARP attacks, and it contains a method to get ARP.

@echo off

lable to loop through the command.

ping -n pause seconds plus one >nul

goto lable

exit

> this is VC's, hope it helps you.

To capture packets, you need to change the NIC mode instead of the IP acquisition mode, and it is best to use a third-party packet capture SDK.

Written with the C function random, the class is imported by default. We can initialize a random number generator in two ways; The first method does not specify a random seed, the system automatically selects the random seed of the previous work in the current tense: random ra=new random(); The second way is to specify an int argument as a random seed:

int iseed=6; random ra=new random(iseed);Now we're going to use the method to generate random numbers.

public virtual int next(int minvalue, int maxvalue);

Usage:,20).

Returns a random number within a specified range (in this case, between 1-20), which is the range you want to draw randomly.

Here's the click to start event, click the button to appear a random number:

private void button1_click(object sender, e)

Displayed in label1.

The main idea is that it is not very complete, and it can be modified slightly.

Basically met your needs. The method is very primitive and you can refer to it.

arraylist lastpath = new arraylist();

}private void button2_click(object sender, eventargs e)

for(int i=0;i

Yes, it can be done. 1. Use httpwebrequest in c to obtain the content of the web page, and then you can extract the content, and what content to extract can be extracted with regular expressions (with regex-like). 2. The keys to operate the web page can be handled by the webbrowser control in C, which can provide the interaction between C and the control in the web page.

What brand of capture card.
