Hi all,
last night, I installed 4.1 on the new ALIX.1C:
http://www.pcengines.ch/alix1c.htm (see dmesg at bottom).
The intended use of the box is a home router/firewall/NAT/DNS/DHCP
for my home "network" of about four computers (heterogeneous).
Everything works fine (as usual with OpenBSD), but
there are a few fine points I need some advice with.
Firstly, swap (i don't really mind reinstalling). Install guide says
On the root disk, the two partitions 'a' and 'b' must be
created. The installation process will not proceed until these
two partitions are available. 'a' will be used for the root
filesystem (/) and 'b' will be used as swap space.
It also says
The 'b' partition of your first drive automatically becomes your
system swap partition -- we recommend a minimum of 32MB but if
you have disk to spare make it at least 64MB. If you have lots
of disk space to spare, make this 256MB, or even 512MB. On the
other hand, if you are using a flash device for disk, you
probably want no swap partition at all. Many people follow an
old rule of thumb that your swap partition should be twice the
size of your main system RAM. This rule is nonsense.
The machine has 256M of RAM, and the storage is a 2G CF card (seen as
wd0). The machine is mostly idle (basically just routes). How much swap
do you think I should set for such operation? For regular operation,
I don't think I need a swap partition at all (how would I do that?
A 'b' partition of zero size, as it has to exist?), but to be able
to save possible core dumps, I am thinking of 300M swap and 300M /var
(to hold /var/crash). Is this reasonable?
Secondly, the network interfaces. The box comes with an on-board
vr0 at pci0 dev 13 function 0 "VIA VT6105M RhineIII" rev 0x96: irq 10
which I currently use as the external iface, and the PIC slot holds
rl0 at pci0 dev 12 function 0 "Realtek 8139" rev 0x10: irq 11
which is used as the internal iface. I also have the following
cards in my hands, and I would like to figure out which combination
of external/internal would give me the "best" performance (if it
makes any difference at all):
Intel PRO/100 S Desktop adapter
3C905C-TX-M Etherlink 10/100 PCI 3
I don't have any idea about what amount of e.g. fragment reassembly the
external/internal iface needs to do, and which card (or which card's
driver) is "best" for that. The machine only has one PCI slot, so one of
these has to be the on-board VIA. Which of the others is "best
supported" in obsd (and which vendor is most open)?
Thirdly, the CF storage. Having read
http://www.kaschwig.net/projects/openbsd/wrap/#mfs
http://blog.innerewut.de/2005/05/14/openbsd-3-7-on-wrap
http://blog.innerewut.de/2005/05/19/openbsd-3-7-on-wrap-revised
http://blog.innerewut.de/2005/06/03/small-update-on-openbsd-3-7-on-wrap
(which apply to 3.7 on WRAP, the predecesor of ALIX), I am concerned
about the CF wearing off. As these articles are from 2005 - do these
things still apply to newer CF cards, and should I therefore set up
a mfs? What else should I do to make the CF card live longer (noatime
comes to mind of course).
Thanks for any suggestions
Jan
