The [J7F4 mini-ITX
\nmotherboard](http:\/\/www.jetwaycomputer.com\/VIA3.html) that I got for
\nmy home server has a VIA C7 processor. One of the feature of the
\nprocessor is the [PadLock Security
\nEngine](http:\/\/www.via.com.tw\/en\/initiatives\/padlock\/hardware.jsp)
\nwith hardware RNG. This is especially useful on a server since they
\nare limited in entropy sources. Linux kernel has support for the VIA
\nhardware RNG in the `via_rng` module.<\/p>\n
Next, install the `rng-utils` package with the rngd daemon. It
\nreads entropy from the hardware RNG, `\/dev\/hwrng`, and feeds it to the
\nkernel entropy pool for `\/dev\/random`. <\/p>\n
Unfortunately, the package is missing an init.d script to start the
\nservice (see [redhat bug
\n215371](https:\/\/bugzilla.redhat.com\/show_bug.cgi?id=215371). The
\n`\/etc\/rc.d\/rc.sysinit` actually has a commented-out line to start
\nrngd. Download the script from the bug and put it in
\n\/etc\/init.d\/rngd. Add the service, `chkconfig –add rngd`, and start it, `service rngd start`.<\/p>\n","protected":false},"excerpt":{"rendered":"
