I need to create a simple http client to a web server and my code is the following:
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <netdb.h>
#include <errno.h>
#include <arpa/inet.h>
struct sockaddr_in wserver, cl;
struct hostent *rem;
int fd, newfd, len, l;
int main(int argc, char *argv[])
{
wserver.sin_family = AF_INET;
wserver.sin_port = 0;//htons(9780);
//wserver.sin_addr.s_addr = inet_addr(rem->h_addr);
wserver.sin_addr.s_addr = inet_addr(argv[1]);
rem = gethostbyname(argv[1]);
memcpy(&wserver.sin_addr, rem->h_addr_list[0], rem->h_length);
if((fd = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)) == -1)
{
perror("create socket");
exit(1);
}
if(connect(fd, (struct sockaddr*)&wserver, sizeof(wserver)) < 0)
{
perror("connect");
exit(1);
}
printf("CONNECTED!!!!!!\n");
return 0;
}I am working with terminal and the errors i get are:
No route to host
or
Connection refused
or
Connection timed out
all coming from connect
