Given the following code:

	[... socket(), getservbyname(), sin <- values ...]

        while (connect(s, &sin, sizeof(sin)) < 0) {
		perror("connect");
		if (++retry > RETRY) exit(1);
		sleep(2);
	}

If the server (to which I am trying to connect) is not there, I get:

	connect: Connection refused             <-- expected
	connect: Invalid argument		<-- WHY??
	    :
	    :
	connect: Invalid argument

What am i forgetting here?

Thanks,
