log send, sendrec, recv and notify system calls

I've a question about MINIX OS.

1 - I would like to log the messages that user or kernel process send to each other through the system call send, recv, sendrec and notify.
Since MINIX is a microkernel OS, I suppose that the best way is to have an TCP socket, listening in INADDR_ANY address. But, I don't know which port should I use. Can anyone help me?

2 - I've the following code:

int main(void)
	int sockfd, new_fd;  // listen on sock_fd, new connection on new_fd
	struct sockaddr_in my_addr;	// my address information
	struct sockaddr_in their_addr; // connector's address information
	socklen_t sin_size;
	struct sigaction sa;
	int yes=1;

	if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
my_addr.sin_family = AF_INET;		 // host byte order
	my_addr.sin_port = htons(MYPORT);	 // short, network byte order
	my_addr.sin_addr.s_addr = INADDR_ANY; // automatically fill with my IP
	memset(my_addr.sin_zero, '\0', sizeof my_addr.sin_zero);

	if (bind(sockfd, (struct sockaddr *)&my_addr, sizeof my_addr) == -1) {


But I get the error that, "Address family is not supported". I don't understand why?
