	Exactly!

	Team guys, does this look to you like nmbd
	never gets past trying to send the reply to a netbios 
	name query?

	send_packet(struct packet_struct *p) 
		calls
	send_udp(int fd,char *buf,int len,struct in_addr ip,int port)
		which calls
	sendto(fd,buf,len,0,(struct sockaddr *)&sock_out,              	
					sizeof(sock_out))
