I think most people don't realise how easy it is to eavesdrop (or

config file and the extra code/complexity it would force onto
everyone, imo.

When ACPI systems fail to boot or act weirdly
I recently tested a Neutrino netbook and sent the dmesg data in. I had to boot with -c and disable acpi in order to do that. It now occurs to me that it might be useful if I sent the contents of both acpidump and pcidump. Is there a place to do that? Do the folks doing acpi development want stuff like this? I can't find anything about this. --STeve Andre'

What good are shared sockets if they aren't usable simultaneously??
use case: I'm always wanting to set up and audio-studio box, and right
now aucat lets me, but what if I want to have myself and a hundred of
my closest friends play a midi-orchestra all routed through the one
box with everyone running their own session on a (remote) frontend? I
could just make a shared 'music' account but that's a workaround for
an awkward system.
Please, don't necessarily make a -g(lobal) flag for aucat, but don't
restrict its flexibility by forcing restrictions in the name of
security. The OS is perfectly competent as handling security with file
permissions like it's designed to. Just add a way for each user to
specify what socket they want sndio to talk to? Like a /etc/sndiorc
and ~/.sndiorc pair. Then to make a global socket you would set it in
your global /etc/sndiorc and then sound would Just Work for every user
and you'd only have to start aucat -l once, but users would still have
to be in the audio group or whatever to use this. Conversely, if
you're actually worried about eavesdropping you can run aucat -l like
usual.
Actually, you could hack this now: make an 'audio' user, at boot do
"sudo -u audio aucat -l" and also create links to the socket that made
for each user on the system. I don't know what's worse: recreating
links at each boot or having to have a config file.

Script checking PERMIT_ values of all lib/run depends
Hello!
Below script checks and displays PERMIT_DISTFILES_CDROM and
PERMIT_DISTFILES_FTP values of 'all' print-build-depends and
print-run-depends ports --- which is very usefull (i think) before
compiling a port.
If someone find it usefull and review the code, i aprreciate.
Regards,
Cem

I guess I need to explain better ;) the buffer sizes do not need to match. the buffer sizes only affect the latency. so when I said "the results may be inconsistent", I meant that with '-b 1', there may be too little buffering to keep the audio smooth, depending on the hardware. anyway, azalia(4) rounds block sizes (there are one or more whole blocks in the hardware buffer) to multiples of 128 bytes. other drivers have different rounding requirements. > Also, with "-b 1024", the delay is around a half-second... not too bad. 'aucat -l -b 1' on azalia will get you a 512 byte hardware buffer (two blocks of 256 bytes each), which is 2.9 ms, timewise. 'aucat -l -b 1024' gets a 2048 byte buffer, which is 11.6 ms timewise. 'aucat -l' gets a 23296 byte buffer, or ~130 ms. since you are recording then playing back, you will have at least 2x the audio hardware buffer size latency ... -- jake...@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org

please send "vmstat -m" and "netstat -m" at a point when the memory
use is medium or high.
if you're using symon to collect your stats, it might be worth
recording and plotting the mbuf stats it can save.

I had forgot to mention the following in my original post...
Obviously, when piping the aucat output through ssh, ssh itself is
going to introduce some delay. However, just trying the following...
aucat -l
aucat -o - | aucat -i -
There is still a ~1 second delay, so it seems that the "bulk" of the
delay was from aucat.
Using
aucat -b 1 -r 11000 -o - | aucat -b 1 -r 11000 -i -
Reduced this somewhat, but not significantly.
Following Hannah Schroeter's advice, reducing the buffer size on the
server instances of aucat reduces the delay dramatically. There is
only a very, very small delay (even through ssh!)
i.e.
aucat -b 1 -l
aucat -b 1 -r 11000 -o - | aucat -b 1 -r 11000 -i -
Works beautifully. Thanks for all the tips.

if you use hard links instead of soft links, you can

no, there's no way for that. Even if we start supporting
``shared sockets'' (i hope so), they will not be usable
simultaneously by multiple users (to avoid evesdropping).
Fine grained access control might solve this problem, but is
too complicated and outside the scope of aucat.

AFAIU the delay cannot be reduced this way (even with a
small -b). Delays are caused by buffering, and ssh(1), as
all the network software (and hardware, eg. your switch) in
the chain use buffers. AFAIK there's no way to set these
buffer sizes (especially the ones in the hardware of your
internet provider :).
aucat(1) has a latency control mechanism to solve similar
problems. To use it you could try to proxy the remote aucat
socket locally, ie to create a local /tmp/aucat-uid/xxx
socket that's forwarded on the remote machine (don't know if
nc(1) can do that). Then you can write a trivial program to
transfer data between your local device and the remote
``xxx'' device.

Thanks. I was unaware of those filesystem drivers and that usage of the term "legacy" (which I usually think of as referring to something from the past and, unfortunately, Windows exists in the present -- Webster: "1. A gift by will esp. of money or other personal property; 2. Something received from an ancestor, a predecessor, or from the past"), though I knew that it was possible (I have a vague recollection that Cutler built Windows NT on some Unix-ey, perhaps micro-kernel thing -- Mach?). But knowing that wouldn't change my approach to this issue -- I wouldn't trust some random third-party driver for Windows to be writing in my FFS filesystem. If I were going to do this with one machine, which at this point I'm not, I'd build an OpenBSD kernel, mount the ntfs partition read-only (which I guess is my only choice) and copy the files from Windows with OpenBSD. I'd certainly trust OpenBSD a heck of a lot more to a. not scribble junk in the ntfs partition that was mounted ro, and b. to write the stuff correctly in the FFS filesystem. /Don > >> As I said in my previous post, pscp and another machine present a >> simple workaround for this issue.

Oh well, why do you suggest bad solutions when good ones have already
been brought up?
find -print0 | xargs -0 is quick and safe
find -print | xargsis quick but not safe
find -exec is not quick but at least safe
command `find` is not safe and has additional problems
Where quick means:
Not starting a new process for each file.
Where safe means:
Handling file names containing white space correctly.
Where additional problems are:
Prone to overflow the max length of command line args.
Try the following:
$ touch important
$ touch 'not important at all.dat'
$ ls -1
important
not important at all.dat
$ rm -f `find . -name "*.dat"`
$ ls -1
not important at all.dat
Ooops.

Or you could do something like
chown -youroptionshere `find . -name "what_you_are_looking_for"`

It is common to use the term "legacy system" to refer to proprietary OS including/especially Micro$oft Windows.

Re: Partition confusion
Thank you all for the clearing this up for me. The presence of mount_ntfs suggested to me that ntfs was supported, but apparently not. I'll either work around this with two machines and pscp on the Windows side, or build a kernel with ntfs support enabled.

slow network thread
hi, I've a problem with the network speed. If I download the a file with openbsd, it has only a speed round about 250 kBit/s I could start several downloads with the same speed. So that a program like aget has a speed from 600 till 900. I've this effect with all programs like Firefox, wget and curl. On the same machine with Windows or Linux the speed goes up from 600 till 900kBit/s. Does somebody know why this happen? Driver problem? or a simple configuration? thanks, Jan
Restricting compiling of ports to permit_*
Hello! Is there any quick way to restrict compilation of ports such that only ports with 'permit_cdrom=Yes' or 'permit_ftp=Yes' are compiled? Regards, Cem

Memory problems on 4.5
Hi all,
after upgrading to 4.5, I've had problems with the memory usage of the box
increasing continuously until if starts to swap and performance becomes so bad
that I have to reboot the box. This does not seem to be related to a specific
program, at least the usual tools don't indicate that one process uses a lot of
memory or that its memory usage increases steadily.
Here's a picture of what I'm talking about -- http://www.larsko.net/mem.jpg
As you can see, memory usage increases quite significantly. The Wed to Sat part
is what it's like now, in the part before there was some other stuff going on as
well. This didn't occur with 4.4.
Does anybody have any suggestions what could cause this and how to fix it? Dmesg
below.
Thanks,
Lars

Partition confusion
I've got OpenBSD 4.5 installed on a Thinkpad X61, dual-booted with Windows XP. XP is at the beginning of the disk, starting at sector 63. The XP slice, to use BSD terminology, is about 10 Gb (the disk is 100 Gb). The OpenBSD slice occupies the rest of the disk. During the OpenBSD install, I created partitions a, b, d, e, f, and g for the mountpoints /, swap, /tmp, /var, /usr, and /home. I don't believe there was any interaction regarding the XP slice during the install. Now I want to mount the XP (ntfs) partition. So, having created /mnt/windows as root, I tried r...@sophie:/mnt$ mount -t ntfs /dev/sd0i windows mount_ntfs: /dev/sd0i on /mnt/windows: Operation not supported So I did r...@sophie:/mnt$ disklabel sd0 # Inside MBR partition 1: type A6 start 20487600 size 174877920 # /dev/rsd0c: type: ESDI disk: ad4s2 label: flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 12161 total sectors: 195371568 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # microseconds track-to-track seek: 0 # microseconds drivedata: 0 8 partitions: #size offset fstype [fsize bsize cpg] a: 316575 20487600 4.2BSD 2048 163841 b: 2104515 20804175swap c:1953715680 unused d: 321300 22908690 4.2BSD 2048 163841 e: 176715 23229990 4.2BSD 2048 163841 f: 12594960 23406705 4.2BSD 2048 163841 g:159364800 36001665 4.2BSD 2048 163841 disklabel: warning, unused partition i: size 7148239195883 offset 17551383986520 disklabel: warning, unused partition j: size 238106791916026 offset 211716520590544 disklabel: warning, unused partition k: size 163974838534045 offset 206347192303801 disklabel: warning, unused partition l: size 271451018559616 offset 5237774174023 disklabel: warning, unused partition m: size 190849433245138 offset 190845464470417 disklabel: warning, unused partition n: size 211668966116211 offset 5864912221576 disklabel: warning, unused partition o: size 17630285786338 offset 76717108839878 disklabel: warning, unused partition p: size 17136519487675 offset 217832169078968 So partition i in the actual label does not describe the XP partition.

Well said, I'm doing that with few ports (ex. wireshark) and I'm maintaining my own xenocara source tree (because lack of support for my graphic card). While asking that question I was only curios why there wasn't place for wake and now there is for tmux. Simple answer was that tmux replaced window and I didn't noticed that. Yes that was my fault... Cheers!
Re: Package problems after 4.5 upgrade.
Thanks for your reply to my message. This is WAG, but did/do you have PKG_CACHE defined? I've never set it explicitly, and it isn't defined on either system. $ env | grep PKG PKG_PATH=ftp://openbsd.mirror.frontiernet.net/pub/OpenBSD/4.5/packages/i386 $ Locate on the upgraded (borked) system doesn't turn up anything that looks like a package to me $ locate gv-3 /usr/local/share/doc/gv/gv-3.html /var/db/pkg/gv-3.5.8p4 /var/db/pkg/gv-3.5.8p4/+CONTENTS /var/db/pkg/gv-3.5.8p4/+DESC /var/db/pkg/gv-3.5.8p4/+REQUIRING $ The upgraded system has a ports tree, which, now that I think about it, hasn't been upgraded. But it's my understanding that packages work independently of any port tree that may be installed locally.

Hi Misc@ and Claudio, I've a new compiled-from-the-last-source OpenBSD Router, lookin' at new cool features. I see a default rib are installed (Loc-RIB and Adj-RIB-In), I can see both with "bgpctl sh rib table Adj-RIB-in" and "bgpctl sh rib table Loc-In". But still, it's always returns nothing when querying prefixes with "bgpctl sh rib address/len". The "bgpctl sh rib neighbor" return the desirable outputs. The others are, when issueing "bgpctl reload" it always failed with these messages (/var/log/messages): Jun 6 16:36:29 GreenRouter-JKT01 bgpd[3750]: /etc/bgpd.conf:223: rib "Adj-RIB-In" allready exists.
