就是阿.... 我在桌上電腦windows XP下用Borland c++ Builder 2007 寫了一個抓網路封包程式由於我是新手所以參考網路上別人寫的依樣畫葫蘆導致自己不是很懂原理寫成功了也可以順利跑.... 但是我把程式帶到筆電 windows vista下給他跑卻一開始就自動跳掉了....我實在不懂原因... 所以我寫了一個小程式碼測試也是一樣的結果 ------------------------以上是廢話很長的前言-------------------------------- 我把測試程式碼完整貼上 #include <vcl.h> #pragma hdrstop #pragma warning( disable: 4996 ) #include <winsock2.h> #include <windows.h> #include "Test.h" #pragma comment( lib, "ws2_32.lib" ) //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma resource "*.dfm" #define LS_HI_PART(x) ((x>>4) & 0x0F) #define LS_LO_PART(x) ((x) & 0x0F) #define LS_MAX_PACKET_SIZE 65535 #ifndef SIO_RCVALL #define SIO_RCVALL _WSAIOW(IOC_VENDOR,1) #endif typedef struct _IP_HEADER_ { BYTE ver_ihl; BYTE type; WORD length; WORD packet_id; WORD flags_foff; BYTE time_to_live; BYTE protocol; WORD hdr_chksum; DWORD source_ip; DWORD destination_ip; DWORD Option_Padding; } IPHEADER; TForm1 *Form1; //--------------------------------------------------------------------------- __fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner) { } //--------------------------------------------------------------------------- void get_this_machine_ip(char *_retIP) { char host_name[128]; struct hostent *hs; struct in_addr in; memset( host_name, 0x00, sizeof(host_name) ); gethostname(host_name,128); hs = gethostbyname(host_name); memcpy( &in, hs->h_addr, hs->h_length ); strcpy( _retIP, inet_ntoa(in) ); } void __fastcall TForm1::Button1Click(TObject *Sender) { struct sockaddr_in sock_sniff; SOCKET sniff_socket = -1; WSAData sa_data; int optval = 1; DWORD dwLen = 0; char packet[LS_MAX_PACKET_SIZE]; WORD ver; IPHEADER *ip_header = NULL; char ipSrc[20], ipDest[20], thisIP[20]; int iRet = 0,i=0; ver = MAKEWORD(2,2); WSAStartup(ver, &sa_data); sniff_socket = socket( AF_INET, SOCK_RAW, IPPROTO_IP ); if ( sniff_socket == SOCKET_ERROR ) { exit(-1); } memset( thisIP, 0x00, sizeof(thisIP) ); get_this_machine_ip(thisIP); sock_sniff.sin_family = AF_INET; sock_sniff.sin_port = htons(0); sock_sniff.sin_addr.s_addr = inet_addr(thisIP); if ( bind( sniff_socket, (struct sockaddr *)&sock_sniff, sizeof(sock_sniff) ) == SOCKET_ERROR ) { exit(-2); } if ( WSAIoctl( sniff_socket, SIO_RCVALL, &optval, sizeof(optval), NULL, 0, &dwLen, NULL, NULL ) == SOCKET_ERROR ) { exit(-3); } while (true) { iRet = recv( sniff_socket, packet, LS_MAX_PACKET_SIZE, 0 ); ip_header = (IPHEADER *)packet; if ( iRet < sizeof(IPHEADER) ) continue; if ( LS_HI_PART(ip_header->ver_ihl) != 4 ) continue; i++; if (i==5) { Label1->Caption=i; break ; } } } //--------------------------------------------------------------------------- 問題就是我在我筆電vista下跑此程式按下按鈕之後就會自動關掉..... 大概知道是因為有寫"錯的會exit" 但不懂錯的原因......因為在我桌電XP下就可以正常執行請問是什麼問題阿??? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.168.78.209
