[En-Nut-Discussion] Getting HTML output via HTTP

[Nelu]

Hi everyone,

I'm new by ethernut /nut-os programming.
>From my C application , I want to read the output of embedded web server.
I'm trying to use Unix socket, connect to embedded web server and then
send/receive
data using write/read methods. The problem is that function 'connect' fails
every time when
try to connect. The embedded web server is running, I can load
http://10.0.0.116 in my browser.
There is the sample application I have used:

int socket_connect(char *ip_addr, in_port_t port){
        struct sockaddr_in addr;
        int on = 1, sock;    

        inet_aton(ip_addr, &addr.sin_addr);
        addr.sin_port = htons(port);
        addr.sin_family = AF_INET;
        sock = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP);
        setsockopt(sock, IPPROTO_TCP, TCP_NODELAY, (const char *)&on,
sizeof(int));
        if(sock == -1){
                perror("setsockopt");
                exit(1);
        }
        if(connect(sock, (struct sockaddr *)&addr, sizeof(struct
sockaddr_in)) == -1){
                perror("connect");
                exit(1);
        }
        return sock;
}

#define BUFFER_SIZE 1024

int main(int argc, char *argv[]){
        int fd;
        char buffer[BUFFER_SIZE];

        fd = socket_connect("10.0.0.116", 80);
        write(fd, "GET /\r\n", strlen("GET /\r\n"));
        bzero(buffer, BUFFER_SIZE);
        while(read(fd, buffer, BUFFER_SIZE - 1) != 0){
                fprintf(stderr, "%s", buffer);
                bzero(buffer, BUFFER_SIZE);
        }
        shutdown(fd, SHUT_RDWR);
        close(fd);
        return 0;
}

Any help will be useful.
Does anybody knows where I can find some sample code?
Thanks in advance,
Nelu Cociag
