You're correct, the athn(4) driver lacks IBSS support.

ral(4) should work.
I have used OpenBSD with this driver in a mesh network (OLSR-based).
This was with rt2661 and rt2560 devices. More recent devices (e.g.
RT3090) should also work in IBSS mode but I have not tested this.

ral(4) is not your only option.
The following drivers advertise IBSS support in their man pages:

  acx(4), an(4), ath(4), atu(4), atw(4), ipw(4), iwi(4), pgt(4),
  ral(4), rtw(4), rum(4), ural(4)

Just in case you are considering ath(4) from the above list as a replacement
for your athn(4) card, note that ath(4) does not support 11g at present.
It only supports 11b and 11a. The man page in OpenBSD 5.9 does't mention
this bug (I've just fixed the man page in -current).

Ad-hoc wifi on athn(4)?

[Ax0n]

I'm working on a project with a local group that involves running a bunch
of systems in Ad-Hoc mode to form a mesh network. I was hoping to join my
daily driver to the mesh, but I'm not seeing any way to get Ad-Hoc/IBSS
mode enabled on athn(4) or any of the USB (urtw, urtnw, run) WiFi adapters
I have kicking around.

Checking man pages of the wifi drivers and ifmedia(4), It looks like the
support just isn't there. If that's the case, I'll pursue another route.
I'm hoping I'm just missing something obvious. Ideas?

muting keyboard bell broken on amd64 -current?

[lists]

Has anyone else noticed that the keyboard bell is no longer muted when
updating -current in the past few days?

$ wsconsctl keyboard.bell.volume 
keyboard.bell.volume=0

is what shows on my machine, but I'm still getting console beeps (I
wasn't before.  My last kernel is showing as being built on Mar 31, and
the "broken" one is from Apr 3 00:54 UTC.

This is on a Thinkpad T420.

I could be misremembering how to disable the bell, but I haven't changed
any configuration other than following the usual instructions in
building -current from source and running sysmerge.

Thanks!

that doesn't matter.

no SDRs IPMI disabled?

[Paul B. Henson]

I just installed 5.9 on a Supermicro X11SSL-F board, and tried to enable
the ipmi driver. During boot, it shows:

ipmi0 at mainbus0: version 2.0 interface KCS iobase 0xca2/2 spacing 1
iic0: skipping sensors to avoid ipmi0 interactions
ipmi0: get header fails
ipmi0: no SDRs IPMI disabled

Any suggestions on how to make this work? The full dmesg is:

Locating appropriate packages for webapp install w/only FreeBSD or Debian package information

[Damon Getsman]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hello.  I am really wanting to write a guide to handling a
semi-complicated install for a web app on obsd (diaspora*) but I'm a
little bit hung up on locating some of the appropriate packages.
Basically, I've got some fairly well proven installation 
instructions for various other OSes, for example Debian (or most other
mainstream) linux, and FreeBSD.  I've run into problems at the point of
locating what packages will be necessary to install on an openbsd
system to fill the same functionality.  I was under a bit of a
misconception that perhaps the package names, if not complete
locations, would be close to the same as in FreeBSD.
Is there any method for locating these packages short of doing
a search on each one of them and locating specific files and/or
developer information?  Just curious as to whether or not I might not
be in the loop for something that'll make life a lot simpler here.
Thanks for any information.

Help with IPsec multiple transform configuration

[Sly Midnight]

Apologies if this was already sent, I am having difficulty with my email
lately and this didn't look like it sent earlier.

Good morning everyone,

I am wondering is there a way to allow either via /etc/ipsec.conf or
/etc/isakmpd/isakmpd.policy to configure a road warrior type of IPsec
VPN access to my router that accomodates multiple types of IPsec clients
that regrettably have limitations in the auth/enc/DH groups they support.

For instance I am trying to get my IPsec/L2TP tunnel VPN working with
two separate clients that support it, but have weird limitations.

My Android phone only works when I set my ipsec.conf file to something
like the following:

ike passive esp transport \
   proto udp from XXX.XXX.XXX.XXX to any port 1701 \
   main auth "hmac-sha" enc "aes" group "modp1024" \
   quick auth "hmac-sha" enc "aes" group "modp1024" \
   psk "presharedkey"

But that won't work with my Chromebook which requires:

ike passive esp transport \
   proto udp from XXX.XXX.XXX.XXX to any port 1701 \
   main auth "hmac-md5" enc "aes" group "modp2048" \
   quick auth "hmac-md5" enc "aes" group "modp2048" \
   psk "presharedkey"

One requires md5 but only with modp2048 while the other might work with
md5, but only with modp1024.  If I don't specify these options than
neither work so I have to, but doing so seems to limit me to one or the
other.

Is there any way I can specify both versions simultaneously?  I don't
see anything in the various manpages about being able to allow multiple
transforms.

Any help would be greatly appreciated.

Sly

Re: simultaneous sound as many users

[Nils Reuße]

As a remark, to simultaneously listen to mpds music and the sound of a 
youtube video in Firefox (running under your user), you have to copy 
your cookie to /var/empty/ (_mpds home dir).


$ doas ls -l .aucat_cookie /var/empty/.aucat_cookie
-rw---  1 nils  nils  16 May 29  2015 .aucat_cookie
-rw---  1 _mpd  _mpd  16 May 29  2015 /var/empty/.aucat_cookie

$ doas sha1 -r .aucat_cookie /var/empty/.aucat_cookie
e8d33a71594c0ba7816e075d17afa81e0ba220ce .aucat_cookie
e8d33a71594c0ba7816e075d17afa81e0ba220ce /var/empty/.aucat_cookie

Should random.seed on shutdown be saved a little later?

[Kevin Chadwick]

So I am currently patching /etc/rc to remount ro which I accept is
special territory. I like ro partitions not only for the lack of need to
fsck and faster boot for systems that have had thee power pulled.

It would be a lot nicer to be able to mount -uw / in rc.shutdown.

Whilst likely not a major issue. I also started to wonder whilst
reading man rc.shutdown, if a daemon or other process could potentially
use /dev/urandom between saving the seed and shutdown so could/should
the random.seed be saved a little later after /etc/rc.shutdown runs?

This looks slightly bogus to me.   Using sndio in record mode, I understand
the privacy concerns. But for playing ?

Thanks. I decided to shorten the whole subsubsection quite a bit more.
It's not as if burning an iso to a CD is already a piece of black magic

It looks like the cdrkit web site has been down for a while.

Point to the debian package instead, or maybe delete altogether?

Thanks for the info everyone. I was going to try one more snap before

so basically the situation is like with the current softdep which is
also dangerous in slow-write-drive low-memory situation and yet it's
in tree.

the question is if it's better to hold those patches in your tree or
push them to the tree so others may try their luck with them. Well you
are the judge here, is WAPBL already on softdep quality level? Thanks!

Thank you for the answer.
It could very well be "RTFM sndio, section AUTHENTICATION"...

You need to share the .aucat_cookie with all the users that are allowed
to play sound at the same time.
Permissions and uid are important, too. Don't try to share with a
symlink.

$ ls -lah /home/*en*/.aucat_cookie

Hi Roman,

you need to share your sndio session cookie between the two users.  I 
got it working previously (the same problem arises with mpd, where the 
daemon runs as a separate user).  There should be a file called 
`~/.aucat_cookie` in your home-dir, and if i remember correctly, you 
just need to copy this file to the second users home dir.  Will check 
later when i'm back at home.


From sndio(7):

AUTHENTICATION

  If a shared sndiod(8) server is running, for privacy reasons only one
  user may have connections to it at a given time (though the same user
  could have multiple connections to it).  Users are identified by their
  session cookie, which is automatically generated by audio or MIDI
  applications upon the first connection to the server.  The cookie is
  stored in $HOME/.aucat_cookie and contains 128 bits of raw random
  data.

  If a session needs to be shared between multiple users, they can
  connect to the server using the same cookie.


Hope that helps
Nils
