Hello OpenBSD World!!!
Long time Linux user who has recently been looking closely at OpenBSD
for secure NAS backup device (home network). This is an immediate need
but I will be shifting a couple of desktops to OBSD 'larrerrer' ;-).
I attach at the bottom of this e-mail my dmesg output for my relatively
simple platform for the NAS (I knowwwwww, it's a waste of an excellent
OS! But I am after the security):
Intel D525MW motherboard (Intel Atom D525 Dual Core 1.8GHz (Supports
64bit), Intel NM10 Express Chipset, Intel GMA3150 Integrated Graphics,
Realtek 8111E GiE NIC, Intel BIOS - Supports ACPI), 4GB RAM, Samsung
HM160HI 160GB SATA 2.5" HDD (Taken from my Samsung NC10 and wiped with
DBAN before installation).
Boot medium was CD from an external, USB-connected Samsung SE-S224Q DVD
Writer using Version 5.0 for AMD64 - SHA256 checksum checked against
three Mirrors.
Only "problem" I encountered preceded installation while the CD was
booting. I received the message "/etc/boot.conf: line too long" but the
CD continued to boot and the installation went through without any problems.
I used these package options: -x* then -game* (removing these packages
from the install - it's a NAS I'm creating here).
I had no problem setting up my static network address etc. etc.
I will install rsync via pkg_add later.
However, I have been trying to find out how OpenBSD handles ACPI/APM
Power Management and disk hibernation.
I have read quite a bit:
1) Michael Lucas' Absolute OpenBSD (2004)
2) Secure Architectures with OpenBSD (2004)
3) Michael Lucas' Absolute BSD (for FreeBSD) (2002)
4) Calomel - you know the one
5) I've tried to search the archived dialogues on Old Nabble (Difficult)
6) I've searched Daemon Forums
7) I've read the FAQ - Always the last place I look ;-)
This is what I feel I have learned:
1) Advanced Power Management on OpenBSD is handled by apmd. I know that
because enabling it through /etc/rc.conf, rebooting and then issuing zzz
puts the PC to sleep. When I tap a key - it wakes up again (exactly
where I left it). GREAT!
2) apmd does not automatically hibernate my disk (unless I am missing
something) - but it is possible that there are ports (I've read about
these for FreeBSD) which might handle disk hibernation: spindown and
diskidle
3) I read somewhere that there is a danger in suspending/hibernating the
disk security wise - but haven't found a full explanation (Is RAM dumped
to disk unencrypted, perhaps?). That would explain why a program to
hibernate the disk isn't included in the default install of OpenBSD.
Unfortunately - searching the OpenBSD mailing lists I have subscribed
too is darn awkward (compared to some other fora - I know some issue
'tarred' archives that can be imported into an e-mail client - ever
considered it? :-) ).
SO... I've come to the fount of all knowledge to seek guidance on the
following:
1) Beyond apmd, is there a default handler of disk hibernation
install-ed/able via default OpenBSD?
2) To use apmd, do I need to maintain a swap partition? Indeed, should I
ALWAYS maintain a swap partition on this simple setup (which is running
fine)? I was hoping to get away without one (currently b: is undefined).
3) If spindown or diskidle exist in the packages/ports - would
installing these provide me with a disk hibernation facility for OpenBSD?
4) Is there another way to manage the PC('NAS') using OpenBSD to
minimize power while the 'NAS' is available 24/7?
All you savvy peeps who know where I am going on this - what's my best
case scenario?
An OpenBSD NAS which doesn't hibernate (Thinks... "Where can I get a
100W PSU?") or can I possibly achieve a NAS that hibernates the drive
and "Wake(s) on LAN"?
I'd settle for simply hibernating the disk (That's about 22W there -
half the power draw) - but if the full monty is possible - I'll keep on
digging.
dmesg details follow this EXTREMELY LONG FIRST POST. Thanks for YOUR
patience, y'all ;-)
Mike
P.S. Anybody know why there is an RTC BIOS error 80 for the clock
battery (See below)? Brand New board, this one.
P.P.S. The i386 32-bit version 5.0 works on this MB too - but I haven't
attached the DMESG for that...
