Client Accepting strange problem. C++ Linux -

i'm making multi-threaded server , ran strange problem. when first client connects server (after run application), accept command returns ip address @ "0.0.0.0", next 1 , others after him addresses valid. im missing or doing wrong? im using gcc , code::blocks

pic if dont understand me (http://i53.tinypic.com/16az1vp.jpg)

libs are:

#include <sys/timeb.h> #include <sys/select.h> #include <sys/socket.h> #include <sys/types.h> #include <sys/wait.h> #include <netinet/in.h> #include <fcntl.h> #include <arpa/inet.h> 

acceptation function , class header

void tcpthread::executelistner() {     int clifd, cid;     socklen_t laddr_len;     char ip[inet_addrstrlen];      printf("[tcpthread] listner thread executed!\n");      while (1)     {         clifd = accept(listenfd, (struct sockaddr *) &cli, &laddr_len); // akceptujemy polaczenie         nonblockingmode(clifd);  // ustawiamy tryb nieblokujacy          inet_ntop(af_inet, &(cli.sin_addr), ip, inet_addrstrlen); // pobieranie adresu ip          printf("[tcpthread] new connection: %s\n", ip);          pthread_mutex_lock(&new_connection_mutex); // blokujemy dostep danych          cid = clients->add(); // dodajemy nowego klienta wstawiamy podstawowe dane         clients->client[cid].sock = clifd;         clients->client[cid].ip.assign(ip);          pthread_mutex_unlock(&new_connection_mutex); // inne thready moga juz korzystac z danych      } }  void tcpthread::nonblockingmode(int sockfd) {     int opts;     opts = fcntl(sockfd, f_getfl);     if(opts < 0)     {         perror("fcntl(f_getfl)\n");         exit(1);     }     opts = (opts | o_nonblock);     if(fcntl(sockfd, f_setfl, opts) < 0)     {         perror("fcntl(f_setfl)\n");         exit(1);     } } 

header file:

#ifndef tcpparser_h_included #define tcpparser_h_included  #include "includes.h" #include "clientclass.h" #include "netmsg.h"  class tcpthread {     public:       tcpthread();       int startserver();        clientclass *clients;    protected:       int runlistner();       int runparser();       static void * entrypointlistner(void*);       static void * entrypointparser(void*);       virtual void executelistner();       virtual void executeparser();        void parsepacket(int clientid, pchar buffer[max_client_buffer], int length);        void nonblockingmode(int sockfd);    private:       pthread_t threadid;       int listenfd;       struct sockaddr_in srv, cli;       pthread_mutex_t new_connection_mutex;  };  #endif // tcpparser_h_included 

i tried

(char *)inet_ntoa(cli.sin_addr) 

but not make diffrience.
