if (fd_client == -1){
perror("fd_sock");
exit(1);
}
add_server.sin_family = AF_INET;
add_server.sin_port = ntohs(4001);
add_server.sin_addr.s_addr = inet_addr("193.39.0.4");
len = sizeof(add_server);
fd = connect(fd_client,(struct sockaddr*)&add_server,len);
if(fd == -1)
perror("connect");
return 0;
