UDP/TCP should check correctly for faults at least. I'm beginning to suspect this person is on a non-x86 platform with dodgy exception handling :-) - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
