If you have a need for a lot of entropy, you can also use the kernel RC4 generator via "sysctl kern.arandom". A couple of other hardware sources are implemented as yarrow entropy sources rather than using the hardware generator directly. I think the support for AMD Geode LX, will be of this form. I suspect that this is more secure than the nehemiah support since it doesn't actually rely on on the hardware alone. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
