本文介绍了仅接收传入数据包的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
随着另一个线程变得混乱,新线程开始了.
我只希望嗅探传入的数据包.我目前处于混杂模式,只想收到通知.尝试向其添加IPLEVEL,并在SIO_RCVALL_IPLEVEL上获得红色的波浪线.我有#include MSTcpIP.h.使用窗口套接字.
New thread started as the other one was getting messy.
I only want incoming packets sniffed. I am currently in promiscuous mode and would like to get only incomming. Trying to add IPLEVEL to this and getting the squiggly red lines on SIO_RCVALL_IPLEVEL. I have #include MSTcpIP.h. Using Window Sockets.
// Set socket to promiscuous mode
// setsockopt wont work ... dont even try it
if ( WSAIoctl( sniff_socket,
SIO_RCVALL_IPLEVEL,
&optval,
sizeof(optval),
NULL,
0,
&dwLen,
NULL,
NULL ) == SOCKET_ERROR )
{
推荐答案
好的...几件事:
1)确保进行此调用的文件具有直接链接到mstcpip.h
(应该具有#include "mstcpip.h"
或类似名称)
2)确保SIO_RCVALL_IPLEVEL
仅定义一次.
您正在使用Visual Studio吗?如果是这样的话:
1)要确保存在#include的链接,请右键单击文件名并打开文件,如果编译器具有清晰的路径,则会打开该文件,否则会显示找不到文件.
2)在解决方案级别搜索SIO_RCVALL_IPLEVEL
定义.
Alright... a few things:
1) Make sure that the file where you''re making this call from has a direct link to mstcpip.h
(should have#include "mstcpip.h"
or something similar)
2) Make sure thatSIO_RCVALL_IPLEVEL
is only defined once.
You''re using Visual Studio? if so:
1) To make sure the linkage is there for #include, right click on the filename and open the file, if the compiler has a clear path to it, it will open, otherwise it will say file not found.
2) Do a solution level search forSIO_RCVALL_IPLEVEL
definitions.
