Do you have softdep enabled?  I've had problems with an overloaded SAN 
(high latency) behind ESXi with OpenBSD.  Mine had a different error 
message, though.

6.0 thanks

[Jonathan Thornburg]

I recently did a fresh install of 6.0 (& immediate CVS-update to -stable)
on a laptop that had been at 5.8-stable.  I've been installing OpenBSD
since 2.8 (fall 2000), and I have to say this was about the cleanest
install yet.  Everything "just works" (even my various non-standard
system hacks).  A big thank-you to all the team!

trouble shooting print errors

[frcc]

  I am getting "Broken Pipe" and or "Scheduler not responding"
  when attempting to print from a laser desk printer directly 
  attached to usb.
  OpenBSD 6.0 recognizes the printer in dmesg and when plugged
  into the usb port.

  I have been running OpenBSD for several years but never tried
  to attach a printer. 

  I also have downloaded a cups ppd driver for the printer and
  placed it in the cups ppd directory.

  If someone can just point me where to research these errors
  I should be able to determine the cause and maybe get the
  brother HL2140 directly attached usb  printer working.

  I see no error messages in dmesg which relate to printing.


  Thanks in advance.

Ok, sorry.

After searching about HostAP, as:
https://w1.fi/hostapd/

It seems Prism Chips run:
http://man.openbsd.org/OpenBSD-current/man4/wi.4
Quote: Host AP
In this mode the driver acts as an access point (base station) for
other cards. Only cards based on the Intersil chipsets support this
mode. Furthermore, this mode is not supported on USB devices.

See the list ;)

Ok, I have found a good candidate: TP-LINK TL-WDN4800. According to TP-Link's 
webpage uses an Atheros AR9380 chip. But, under athn(4) OpenBSD's man page, 
this chip doesn't appears for OpenBSD 6.0 ... but it appears under OpenBSD's

Indeed, BCM4366 won't work.

There are many Atheros AR9280 devices on sites such as ebay.
And some vendors like pcengines still sell cards with this chip.
You could also search for other chip names listed in the athn(4) man page.

 I agree. Microserver Gen8 is a fantastic box to deploy this type of scenarios. 
My idea is to buy a SSD drive, configure this harddisk as RAID0 in B120i and 
fire up OpenBSD ..

 I prefer to avoid to buy an access point. I can wait best support and data 
rates from OpenBSD side in future releases ...

Many thanks Stefan and Ze for your answers. But thinking about it maybe it is a 
good idea to limit throughput to 150Mbps or less at this first stage. I can 
wait until OpenBSD will support more data rates.

I have discoverd that Asus AC88 AC3100 uses BCM4366 chip, but if I am not wrong 
this chip is not supported under OpenBSD, is it right?

Thanks.

The Microserver Gen8s are really nice machines for the application you 
describe, once you set the disk controller to something sensible (as previously 
reported). 

When it comes to your primary question I don't have a good answer, but in case 
those boards are not suppurted it's worth keeping in mind one other option: get 
the highest quality access point or 'wireless router' you can afford, configure 
it as access point only (no dhcp or routing, leave that to the OpenBSD tools)

Well, given the lack of 40Mhz channel support, the best we can do in
theory is 72.2 Mbit/s (20 MHz channel with SGI, see mcsindex.com).
But since we don't support Tx aggregation yet either, protocol overhead
eats up a huge chunk of that.

The peak iwm(4) Tx rate I have measured with tcpbench(1) is about 20 Mbps.
Receive can be faster because 11n APs usually send aggregated frames and
we do support receiving such frames.

I'm afraid you won't get 300 Mbps from any wifi device on OpenBSD.
Our 802.11n support is still in very early stages.

The best access point OpenBSD can offer uses obsolete AR9280 Atheros
hardware with 802.11a data rates (theoretical maximum 54Mbit/s).
802.11n is not yet supported by any driver which has hostap support.

For your kinds of requirements, the best solution is an external
access point connected to your OpenBSD box with gigabit ethernet.

  802.11n operation is currently limited to data rates MCS 0 to MCS 7

Which means you'll get at most 150Mbps with a 40 MHz channel under
perfect conditions.  If you want that kind of bandwidth (actually, even
if you don't) I'd advise getting a dedicated access point or a wi-fi
router that you can configure as such.

PCI Express wireless adapter supported under OpenBSD

[C. L. Martinez]

Hi all,

 I would like to install OpenBSD on a HP Microserver Gen8 to act as a firewall 
and hostap. I am searching what components I need and I have a doubt about what 
wireless interface I need to buy to use it as a hostap under OpenBSD.

 I have found only these:

 - Asus PCE-AC88 Wireless 5GHz PCI-E AC3100
 - Asus PCE-AC68 PCI-E WiFi Dual-Band AC1900

 Searching in ASUS's web, I didn't find any info about what chip use these 
adapters. Are they supported under OpenBSD? Do you recommend any other wireless 
adpater (PCI-e)?? Throughput needs to be 300 Mbps, at least.

Thanks.
