socket programming error

Hi everyone, I got errors when I compiled my server and client program.
This is my server program. I am also using ubuntu 11.10.

#include <netdb.h>
#include <netinet/in.h>
#include <string.h>
#include <cstdlib>
#include <iostream>
#include <stdio.h>
#include <arpa/inet.h>

#define PORT 4547

/*int parseARGS(char **args, char *line)
int tmp = 0;
args[tmp] = strtok(line, ":" );
while ((args[++tmp] = strtok(NULL, ":" )) != NULL);
return tmp -1;

int main(int argc, char *argv[])
//char *header[4096];
int listenSOCKET;
int connectSOCKET;
socklen_t clientADDRESSLENGTH;
struct sockaddr_in clientADDRESS, serverADDRESS;
char recvBUFF[4096];
//Image *recv_img;
//char *filename, *filesize;
//FILE *recvFILE;
//int received = 0;
//char tempstr[4096];

//int count1=1, count2=1, percent;

listenSOCKET = socket(AF_INET, SOCK_STREAM, 0);
if (listenSOCKET <0)
printf("Cannot create socket\n");
return 1;
//PORT = atoi(argv[1]);
serverADDRESS.sin_family = AF_INET;
serverADDRESS.sin_addr.s_addr = inet_addr("");
serverADDRESS.sin_port = htons(PORT);

if (bind(listenSOCKET, (struct sockaddr *)&serverADDRESS, sizeof(serverADDRESS))<0)
printf("Cannot bind socket\n");
return 1;

listen(listenSOCKET, 5);
clientADDRESSLENGTH = sizeof(clientADDRESS);
connectSOCKET = accept(listenSOCKET,(struct sockaddr *)&clientADDRESS, &clientADDRESSLENGTH);
if (connectSOCKET<0)
printf("Cannot accpet connection\n");
return 1;
if(recv(connectSOCKET,recvBUFF,1,0) == 0)
printf("ERROR on receiving");
//memcpy(recv_img,recvBUFF, sizeof(recvBUFF));

return 0;

I got an error like cannot bind socket.
I run the program like ./server4.o 4547.
why is that so? If anyone know how to solve it. pls kindly tell me. thanks
Are you running client and server on the same PC...?
no different pc
Instead of this,
serverADDRESS.sin_addr.s_addr = inet_addr("");

please use local address this will solve your problem..
serverADDRESS.sin_addr.s_addr = inet_addr("");
