Hi,
I have two SuperMicro E31220L based systems - both had identical
/etc/sysctl.conf - I then shifted them from 9.0-R to 9.0-Stable (as of
2012/12/03).
Now I've noticed of them complains at boot time that a bunch of OID's are
missing - and sure enough:
"
sysctl kern.random
sysctl: unknown oid 'kern.random'
"
But the other system returns these fine.
One system ID's as 'Intel E31220L @ 2.20Ghz' - the other ID's as 'Intel
E31220L V2 @ 2.30Ghz' the V2 system is apparently 'missing' the kern.random
stuff.
The only reason I can think for the OID's not being present is if one
system is using hardware RNG? - Though 'man 4 random' states:
"The only hardware implementation currently is for the
VIA C3 Nehemiah (stepping 3 or greater) CPU. More will be added in the
future."
Is there any other reason why they would have 'disappeared' on the non V2
system? (in fact, looking at the Feature2 line I can see 'RDRAND' on the V2
system, hmm so I'm guessing that's it?!)
Thanks,
-Karl
