what methods do folks currently use (on NT and unix)
to generate a random seed ...
mr. hodges,
solaris has a good trng product called
cryptorand. i've reviewed its internals
closely. cryptorand works by hashing
kernel memory. the pointers in kernel
memory get shuffled constantly by external
I've been putting a cheap sound card in every machine, not connected to
any external wires, cp'ing from it on reboot. Seems to generate a nice
chunk of randomness, but I've never measured it.

Thanks to everyone for the info -- it's definitely helpful.
Yesterday, I had a brain fart and searched by archive of this list for
"random" and neglected "entropy". This popped up using the latter (slightly
embarrassing that it's in response to a v. similar question I'd asked not long
ago
A search on "randomness" in google.com turns up David's pages as the top two
hits..

ArcotSign was discussed in 1998 and http://www.arcot.com in 1999
and 2000. I haven't read everything to remind myself of any conclusions
that were reached.

turn it up.
