How do I disable this without causing entropy starvation for "typical" use cases (ssl? ssh?)? I googled a bit and found nothing at all about how to disable excessive harvesting. # sysctl -a | grep harvest kern.random.sys.harvest.ethernet: 1 kern.random.sys.harvest.point_to_point: 1 kern.random.sys.harvest.interrupt: 1 kern.random.sys.harvest.swi: 0 These are the knobs I know about. Is it enough to turn kern.random.sys.harvest.ethernet and kern.random.sys.harvest.interrupt to 0, or are there other things I need to do too? /Daniel Eriksson
