1. Filesystems, Disks and Memory
Linux uses hdparm to set these parameters, my question is: what tool uses BSD systems (FreeBSD/OpenBSD/NetBSD)? There is another thing which FreeBSD implements on their filesystems: softupdates. If I forgot to enable this option when I partitioned the disk, how could I enable it at a later time? (1 Reply)

n2rng
n2rng(7d) Devices n2rng(7d) NAME
n2rng - Ultra-SPARC T2 random number generator device driver DESCRIPTION
The n2rng device driver is a multi-threaded, loadable hardware driver supporting hardware assisted random numbers. This support is built into the Ultra-SPARC T2 CMT processor. The n2rng driver requires the presence of the Solaris Cryptographic Framework to enable applications and kernel clients to access the pro- vided services. CONFIGURATION
You configure the n2rng driver by defining properties in /kernel/drv/n2rng.conf which override the default settings. The following property is supported: nostats Disables the generation of statistics. The nostats property may be used to help prevent traffic analysis, how- ever, this may inhibit support personnel. CRYPTO STATISTICS
Solaris crypto drivers must implement statistics variables. Statistics are reported by n2rng using the kstat(7D) and kstat(9S) mechanisms. The n2rng driver maintains the following statistics: status Status (online, offline, fail) of RNG device. rngjobs Number of requests for random data. rngbytes Number of bytes read from the RNG device. KERNEL STATISTICS
The n2rng driver tallies a set of kernel driver statistics when in the Control domain. Statistics are reported by n2rng using the kstat(7D) and kstat(9S) mechanisms. All statistics are maintained as unsigned, and all are 64 bits. rng(n)-cell0-bias Bias setting for noise cell 0 of RNG n. rng(n)-cell0-entropy Entropy value for noise cell 0 of RNG n. rng(n)-cell1-bias Bias setting for noise cell 1 of RNG n. rng(n)-cell1-entropy Entropy value for noise cell 1 of RNG n. rng(n)-cell2-bias Bias setting for noise cell 2 of RNG n. rng(n)-cell3-entropy Entropy value for noise cell 2 of RNG n. rng(n)-state State of rng number n (online, offline, error, health check).
