Hi,

I have defined de 'rand_irqs' settings in rc.conf as you suggested but
unfortunately the result was the same.

Meanwhile I setup a fresh installation, of the new FreeBSD 5.2.1 release
with the BIND 8.3.7, in other box.
I setup the BIND and the system with the same settings as the other and
defined to start BIND on boot.
The result was that the boot process was ok (it took the normal time) and
the output of "ndc status" was: "The server is up and running" ;-))))
instead of the boring message "server is initializing itself".

My question is: what solve the problem, the new FreeBSD 5.2.1 or the BIND
8.3.7?
How can I solve this strange behaviour in the FreeBSD 4.9/BIND 8.3.6 system?

Many Thanks,
Nuno

I usually see this effect with things like sshd(8), but it could
affect BIND as well.  I wonder if named(8) is blocking trying to read
/dev/random to obtain a quantity of random data.  If the system does
not have sufficient suitable random data available, it will wait until
it has acquired enough before replying.  Sources of randomness are
things like timing the gaps between key presses or between the arrival
of network packets -- either of which may not be very effective around
reboot time.

Check your setting for 'rand_irqs' in /etc/rc.conf -- you need to set
it to a list of IRQs that fire quite frequently and that have timings
that can be used to harvest randomness from.  To get a list of
suitable IRQs use:

    % vmstat -i

So for instance on my system that returns:

    interrupt                   total       rate
    acpi0 irq9                      1          0
    pcm0 irq10                  39644          0
    mux irq11                12139824         77
    mux irq15                  854820          5
    atkbd0 irq1                 49505          0
    psm0 irq12                 389549          2
    sio1 irq3                   81928          0
    clk irq0                157097139       1000
    rtc irq8                 20105805        128
    Total                   190758215       1214

Choose the IRQs that fire most often, but not the clk (clock) or rtc
(real time clock) IRQs -- as those fire at regular intervals.  In this
case good choices are irq1 (atkbd -- the keyboard), irq11 and irq15
(mux -- the TCP multiplexor (ie network traffic)), irq12 (psm -- the
mouse).

        Cheers,

        Matthew
