I've just started learning the basics of sockets (Linux). I tried my hand at a small example, but it doesn't work and I have no idea what's wrong.

I get a "Connection Refused" error message.

Here's my code:

#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <netinet/ip.h>
#include <stdio.h>
#include <string.h>
#include <errno.h>

int main() {
    int c;
    c = socket(AF_INET, SOCK_STREAM, 0);
    if (c < 0) {
        printf("Error in creating socket! %s\n", strerror(errno));
        return 1;
    }

    struct sockaddr_in server;
    memset(&server, 0, sizeof(server));
    server.sin_port = htons(1234);
    server.sin_family = AF_INET;
    server.sin_addr.s_addr = inet_addr("127.0.0.1"); //local host
    if (connect(c, (struct sockaddr *)&server, sizeof(server)) < 0) {
        // Here is my error
        printf("Error when connecting! %s\n",strerror(errno)); 
        return 1;
    }

    while(1) {
        char msg[100];
        printf("Give message: ");
        fgets(msg, sizeof(msg), stdin); 
        send(c, &msg, sizeof(msg), 0);
        char resp[100];
        recv(c, &resp, sizeof(resp), 0);
        printf("Received: %s\n", resp);
    }
close(c);
}

EDIT

Of course ! the error was actually in the server. I simply found it weired that the client sent the message, so I narrowed my view, didn't even bother looking back at the server.

Since the error seems to be also in my server, I might end up asking another question and linking it here

Server was listening to (12345) ...
