Hunting down some headers

[DamagePlan]

So I have a program I need to run but when I compile it I get some undefined symbol errors.
Here they are.
{code]
Undefined
symbol
bind
accept
listen
socket
inet_addr
[/code]

So it appears I'm missing some of the following header files.
Perhaps only the socket.h.
Everywhere I look online, everyone is trying to run in windows and they need to use winsock. I'm on linux and I can't find the header file, can anyone help?

#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <string.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include "concert.h"

These headers should be in /usr/include on most Linux boxes.
