Na ena programmataki pou tha kanei listen sto 6699 kai tha stelnei
otidipote dexetai sto stdout (ara trexte to san "./a.out > log").
Den kanei fork, giati den nomizw na ginetai connect apo perissoterous
apo ena clients... Bebaia isws na perimenei apantisi autos pou
syndeetai opote mono enas sniffer mporei na mas boithisei. Dokimaste
to kai peite mou (edw pou eimai den mporw na to dokimasw). (Compile me
"gcc 6699.c").

#define LISTENQ 1024
#define SA struct sockaddr
#define SERV_PORT 6699

int main()
{

	int listenfd, connfd;
	socklen_t clilen;
	socklen_t len;
	unsigned char buff[2];
	struct sockaddr_in cliaddr, servaddr;
	char topbuff[1024];

	listenfd = socket(AF_INET, SOCK_STREAM, 0);

	bzero(&servaddr, sizeof(servaddr));
	servaddr.sin_family = AF_INET;
	servaddr.sin_addr.s_addr = htonl(INADDR_ANY);
	servaddr.sin_port = htons(SERV_PORT);

	bind(listenfd, (SA *) & servaddr, sizeof(servaddr));
	listen(listenfd, LISTENQ);

	len = sizeof(cliaddr);

	connfd = accept(listenfd, (SA *) & cliaddr, &len);
	fprintf(stderr, "connection from %s, port %d\n",
	 inet_ntop(AF_INET, &cliaddr.sin_addr, topbuff, sizeof(topbuff)),
		ntohs(cliaddr.sin_port));

	buff[1] = '\0';

	for (;;) {
		if (read(connfd, buff, 1) == 0)
			break;
                /* fprintf (stderr, "%x.", (int)buff[0], buff); */
		fprintf(stdout, "%s", buff);
	}

	close(connfd);
