server-client programming problem

SERVER SIDE PROGRAM

if(bind(sockfd, (struct sockaddr *) &serv_addr,sizeof(serv_addr)) <0)
{
    error("Error in binding");
}

/* added newly */

while(1)
{
   listen(sockfd,5);
   newsockfd = accept(sockfd, (struct serv_addr *) &client_addr,&client_len); /*this will actually receive the client address and the length of it*/
   printf("The client ip address is:");
   printf("%s\n", inet_ntoa(client_addr.sin_addr));
   PID=fork();
   if(!PID)
   { 
     printf("Forking the new child");        
      for(;;)
      {
      /* bzero(buffer,256);  */
      n = read(newsockfd,buffer,255);
      if (n < 0)
      error("ERROR reading from socket");
      printf("Here is the message: %s\n",buffer);
      n = write(newsockfd,"I got your message\n",18);
      if (n < 0) error("ERROR writing to socket");
       bzero(buffer,256);
      }
   }
}

CLIENT PROGRAM:

sockfd = socket(AF_INET, SOCK_STREAM, 0); 
if(sockfd<0)
{
    error("Error in opening of socket");

   }
}   

When I try to connect some clients to server, server receives first message as blank message from the first client and it prints the first client ip as 127.0.0.1 and for other clients the server prints their ip address correctly and also receives message from the client? y is it so? y is the server receiving the first message as blank message from the first client? y is the server printing the ip address of first client as 127.0.0.0? Can some body help me.....

Thanks in advance.
