Hello Hello Hello. At the moment i am working on contacting my web server through my browser. I have got it working. I can communicate with my web server by typing http://localhost into my browser.
// fakewebserver.cpp : Defines the entry point for the console application.

#include <iostream>
using namespace std;
#include <winsock2.h>

int _tmain(int argc, _TCHAR* argv[]){
while(true){
WSAData wsadata; if(WSAStartup(MAKEWORD(2,2), &wsadata) != NO_ERROR){
cout<<"Error at WSAStartup\n";
return 0;
}
SOCKET listenSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if(listenSocket == INVALID_SOCKET){

WSACleanup();
return 0;
}
sockaddr_in serverService;
serverService.sin_family = AF_INET;
serverService.sin_addr.s_addr = INADDR_ANY;
serverService.sin_port = htons(LISTEN_PORT);
if(bind(listenSocket, (SOCKADDR*)&serverService, sizeof(serverService)) == SOCKET_ERROR){
cout<<"Error at bind: "<<WSAGetLastError()<<endl;
closesocket(listenSocket);
WSACleanup();
return 0;
}
if(listen(listenSocket, BACKLOG) == SOCKET_ERROR){
cout<<"Error at listen: "<<WSAGetLastError()<<endl;
closesocket(listenSocket);
WSACleanup();
return 0;
}
cout<<"Server connected\n\n";
while(true){
struct sockaddr_in from;
int fromLen = sizeof(from);
SOCKET msgSocket = accept(listenSocket, (struct sockaddr*)&"66.183.109.234", &fromLen);
if(msgSocket == INVALID_SOCKET){
cout<<"Error at accept: "<<WSAGetLastError()<<endl;
closesocket(listenSocket);
WSACleanup();
return 0;
}
cout<<"Clinet: address "<<inet_ntoa(from.sin_addr)<<" port: "<<ntohs(from.sin_port)<<endl;
char HTML[] = "<HTML><TITLE></TITLE><BODY><H1>Hi!</H1></BODY></HTML>";
char sendBuff[1000];
char recvBuff[1000];
int bytesSent = 0;
int bytesRecv = 0;
//recieve from client
bytesRecv = recv(msgSocket, recvBuff, (int)strlen(recvBuff), 0);
// istream in(msgSocket);
cout<<bytesRecv;
if(bytesRecv == SOCKET_ERROR){
cout<<"Server, error at recv() "<<WSAGetLastError()<<endl;
closesocket(listenSocket);
WSACleanup(); return 0;
}
recvBuff[strlen(recvBuff)] = '\0';
//send response to client
cout<<"Server recieved message: "<<recvBuff<<" from Client address: "<<inet_ntoa(from.sin_addr)<<" port: "<<ntohs(from.sin_port)<<"\nbytes recv: "<<bytesRecv<<endl;
sprintf(sendBuff, "%s %d %s", PROTOCOL, 200, "OK");
send(msgSocket, sendBuff, (int)strlen(sendBuff), 0);
cout<<"Server sent message: "<<sendBuff<<endl;
//send content
send(msgSocket, HTML, (int)strlen(HTML), 0);
cout<<"Server sent message: "<<HTML<<endl;
closesocket(msgSocket);
}
closesocket(listenSocket);
WSACleanup();
return 0;
}
}this will output Clinnet : address 127.0.0.1 port : 4943
I know that 127.0.0.1 is the loop back address. Why cant i type in my external ip address into the browser. I read somewhere that i need to set up a dns sub domain, for this to work. It kind of makes sense to me. Can anyone tell me what i cant connect to my web server with with external ip address?
thanks
