Hi misc@,

Just wondering, is there still no support for the aio(2) programming
interface in OpenBSD? (Running 4.1 and I cannot find it)

In January 2003 it was being worked on, but what is the status now?

hi folks,

I saw this performance issue with pf on a AMD64firewall: below is the link

http://www.nabble.com/firewall-is-very-slow%2C-something%27s-wrong-t4572...

it states that pf on 4.2 performs much better than in 4.1. having said
this, is it possible to be able to just update pf's feature instead of
going through the entire OS upgrade? since im really going after the
features of pf, and happy with how 4.1 is.

any comments are awesomely appreciated.

thanks,
-beavis

thanks for the reply guys, I currently run CARP and pfsync on both
boxes (upgrade can be done with less downtime) though i haven't tried
to stress test my setup, i guess this upgrade is do-able. instead of
coding (im not a coder).

Just an update...it hangs on the message "Loading /CDBOOT" not cdbr as
previously posted. Sorry about that.

Hello all,

Please CC to me directly as I am offlist...

I am building a LiveCD/LiveDVD based on OpenBSD 4.1 snapshot. I know this
is an unofficial page, but I followed the instructions here:
http://openbsd-wiki.org/index.php?title=LiveCD

I'm using 4.1 because of the libraries required on the LiveDVD...

This looks normal. I've yet to find a CF-IDE Adpater combination that makes it into full Ultra-DMA mode 4.

CF Media is generally slower than modern high perf. disks, depending a lot on the manufactuer quality.

For my bsd-appliance project, I use CF media strictly for booting a MD/RD kernel image. If you're doing a full-install on the CF card, you've got the wrong approach. You're going to nuke your CF media with all of that atime update and IO cache flush overhead.

There's no progress(1) in ...

I am running an ALIX/4.1 with 2G CF card as its sole storage,
and mounting with noatime and softupdates helped the speed
a lot.

Hi,

I hope you succeed. I'd be very itnerested in a live cd/dvd for obsd.
As you say, it's ideal to test hardware, but I don't have to time to
do it myself. Btw, why obsd 4.1?
Do you plan to upload the iso to some site? There were some projects,
like quetzal and olivebsd, but they died, I think.

good luck,

Pau

qemu doesn't work for some reason. Anytime I try and use qemu I get the
error "Cannot initialize SDL library..."

Yes, I have tried it in different hardware. What exactly do cdbr and
cdboot do? I get the screen that says "OpenBSD boot loader" (with the
hardware fd1 etc listed), with the "Loading /CDBOOT" above it and it just
hangs.

cdbr is listed in the installation instructions as the cdboot loader.
cdboot is the second stage boot loader IIRC. Don't hesitate to correct me
if I'm...

<SNIP>

Some additional info: I did install the qemu from package. Running qemu
under X gives me this:
qemu -cdrom livecd.iso -boot d

It might. Who knows? CDs are a much more standard technology. Try it
first with CDs and make sure that works. Always work from a known
good, right?

You could always netboot (PXE) these computers, you know.

Thanks for quick response, I want to set-up a Primary Domain Name
Server, so that I hosts my own domain. Is there any good wiki that I can
follow?

You have a few options.

- http://www.isc.org/index.pl?/sw/bind/index.php - look at the
Administrator Reference Manual.

- Have a look at the default configuration under /var/named/etc/ and
/var/named/master/; the configuration is essentially already in place
(all you need to do is add your zone data) and you've got a
functioning DNS server which is authoritative for your zone(s).

Thanks for your response.

I'm aware that iTunes filters traffic outside of its subnet, I'm
thinking a pf.conf(5) rule something like

nat on enc0 inet proto udp from $subnet_A to 224/4 port = 5353 ->
$subnet_B_gateway static-port

might successfully fool iTunes into not filtering the traffic. This
wouldn't successfully route the packet, however, as my routing table
shows

224/4 127.0.0.1

which I guess means that multicasted traffic needs the assistance of
mrouted(8) or the ...

It already exists. You can run OpenBSD DomUs (ie. run OpenBSD as a Xen
"guest"**), but AFAIK you still can't run OpenBSD Dom0s (ie. run
OpenBSD as a Xen "host"**).

See http://www.ropersonline.com/openbsd/xen/

** This is a flawed metaphor, because Xen is a _hypervisor_, NOT an
emulator. The Domain U installs are not really running as guest OSes,
and the Domain zero installations are not really running as host OSes.
But you need at least one Dom0 (which when I last looked into this
still could n...

no

I would like to vouch for openbsd working great as a guest, but my
guest has crashed a dozen times. However I think this is due to the
debian linux dom0 having broken sata code for the controller in use.
dom0's dmesg is filled with debug statements from sata related places
in the kernel that should never be printed. We're in a messy
de-centralized linux development world trying to get a stable dom0
patched together. It sucks.

The paravirtualization port appears dead to me. I've tried ...

This is what I meant to hint at earlier: Running an OpenBSD DomU in
connection with, say, a Linux Xen Dom0 possibly makes that OpenBSD
installation subject to bugs in the hypervisor/Dom0, and that may be
unavoidable. The question is, is that a worthwhile trade-off? Is this
a reason not to support Xen? Or should the user be given that option
regardless of the inherent limitations and consequences?

--ropers

For what it's worth, I plan on setting up a Xen box with an Ubuntu
Dom0 and an OpenBSD DomU Real Soon Now, as soon as I get my trashpile
computer fixed.
(It's currently running Ubuntu with faulty RAM, because I got ripped
off by some US-Americans* via ebay, and I can't afford to throw more
money at it to fix it, because I'm now long term ill AND on
wellfare**... yadda, yadda, whine, whine ;-P )

Anyway, I plan on telling the misc list if and when I manage to set
this up. Of course, dmesgs will be...

I have experienced similar behaviour, except that, with me, after I do an
archive extraction, or a file concatenation of many files, while the file
system only shows one set of files, additional files which were deleted after
the extraction, continue to be listed as existing when I try to do operations
on the directory as a whole.

$ cp -R dir new/
Failure! Cannot copy some non-existent file.

$ cp -R dir/*.x new/
Works.

It is very strange.

It does. I copied another album onto an SD mounted there and listened

Hello,
perhaps output of the following will be more useful:
mount |grep /mnt/usb
df /mnt/usb
df -i /mnt/usb
ls -la /mnt/usb
fsck /mnt/usb

The cp program complains about the target files, not the source.

I've got a Compaq DL380G1 with a Smart 5300 card (ciss). I've got an
array plugged into port 1, and a tape plugged into port 2. The BIOS
setup for the card sees everything, but OpenBSD doesn't see the tape,
nothing in dmesg. I don't even see the second scsibus for ciss. Any
suggestions?

IIRC (and thats debatable as this is old memory) a number of the compaq
array cards do *not* support tape devices behind the scsi bus. it was
only intended for connecting further disks to.

i think its expected to see it in the bios though even if it can't be
used in pass-through configuration.

if this applies to your device, it will be documented in the 5300
technical info.

Use pftcl -vsA, it will return you the anchors nested in authpf/* like:
authpf
authpf/user(pid)
authpf/anotheruser(pid)

The use pfctl -a 'authpf/user(pid)' -sr to display user's rules.

There are at least three open bug reports related to re hanging when
used at gigabit speeds. You might try forcing it to 100baseTX.
