why cant i get a responce from the server?
i cant get response from server program just stalls.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <unistd.h>
#include <string.h>
#include <netdb.h>
#include <sys/types.h>
#include <netinet/in.h>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <iostream>
using namespace std;
#define PORT 80
#define MAXDATASIZE 100 // max number of bytes we can get at once
int main(int argc, char *argv[])
{
int sockfd, numbytes;
char buf[MAXDATASIZE];
struct hostent *he;
struct sockaddr_in their_addr; // connector's address information
if (argc != 2) {
fprintf(stderr,"usage: client hostname\n");
exit(1);
}
he=gethostbyname(argv[1]);
cout<<"Host name : "<<he->h_name<<endl;
cout<<"IP Address : "<<inet_ntoa(*((struct in_addr *)he->h_addr))<<endl;
sockfd = socket(AF_INET, SOCK_STREAM, 0);
their_addr.sin_family = AF_INET; // host byte order
their_addr.sin_port = htons(PORT); // short, network byte order
their_addr.sin_addr = *((struct in_addr *)he->h_addr);
memset(&(their_addr.sin_zero), '\0', 8); // zero the rest of the struct
if (connect(sockfd, (struct sockaddr *)&their_addr,
sizeof(struct sockaddr)) == -1) {
perror("connect");
exit(1);
}
char *msg = "GET /";
int len;
len = strlen(msg);
if (send(sockfd, msg, len, 0) == -1)
perror("send");
if ((numbytes=recv(sockfd, buf, MAXDATASIZE-1, 0)) == -1) {
perror("recv");
exit(1);
}
buf[numbytes] = '\0';
cout<<"Received: "<<buf;
close(sockfd);
return 0;
}
is there something wrong with the code?
