Could you give me some hints about serial console thing? I dont have any experience with it. Do I need to have some special cables etc? I have two machines one linux the other openbsd. If no special cables necessary I will try to play with serial console thing. So still not able to show a dmesg. I'm guessing, as it sounds fairly new-ish, that you have an option to run the SATA ports in AHCI mode, and obviously, you are not. I've found at least some AHCI controllers in compatibility mode are between glacial and unusable. Yours sounds like it was glacial during install and unusable after boot. Dig through your BIOS for options to change the mode of the SATA ports to AHCI (enhanced good non-sucky no idea what they'll call it). You will know you are in AHCI mode if your disks come up as sd rather than wd devices. As you have guessed there is a switch in bios about sata modes. There are 3 sata modes: ide,ahci and raid. When ide selected the disc is recognised as wd and when ahci it is sd. I reinstalled to a different hard disk which is older, same thing happened.

Which kernel are you booting? If you only boot 'bsd', you need a fully-installed system to use that. You need to make sure to boot the 'bsd.rd' kernel.

vfs.nfs.iothreads
On 5.2/i386, man sysctl says To adjust the number of kernel nfsio threads used to service asynchronous I/O requests on an NFS client machine: # sysctl vfs.nfs.iothreads=4 The default is 4; 20 is the maximum. See nfssvc(2) and nfsd(8) for further discussion. Does it still apply? The default now seems to be # sysctl vfs.nfs.iothreads vfs.nfs.iothreads=-1 which scales itself to 4 when I copy a file from a NFS server. Should I be touching vfs.nfs.iothreads manually? Setting it to 20 just panicked my 5.2/i386. Also, neither nfssvc(2) nor nfsd(8) seems to contain any further discussion of this. Jan

I could provide a list of things that need doing in locales/wireless/IPv6 if any of those areas are of interest to you. They are. Except for locales, never used them. Cool! Below is a todo list written off the top of my head. Wireless: There are performance issues with ral(4) and possibly other devices. I believe it's because the rate adaptation algorithm is too basic and doesn't cope well in noisy environments. The dragonfly commit log for ral(4) contains some interesting work by sephe@dragonfly which I've been taking a closer look at. http://gitweb.dragonflybsd.org/dragonfly.git/history/HEAD:/sys/dev/netif/ral (Careful: Some of sephe's commits have been reverted in a giant sync with freebsd commit -- I'm not sure whether the person who made that commit knew what he was doing...) Note that parts of these rely on other changes made to the generic net80211 layer in dragonfly. I hope that we might be able to fix performance issues with ral(4) and perhaps other chips based on sephe's work. But this needs a bit of research. I'm not entirely sure if that really is the case. For some reason, hostap mode seems to be affected most by the performance issues, which is why I believe the rate adapation approach might to blame (but it might just as well be something else). ral(4) does not support power saving in hostap mode for rt2560 and rt2661 chips. Power-saving support for newer chip variants exists. In general, adding support for power-saving in hostap mode to any drivers which support hostap mode is needed. See here for the spec: http://standards.ieee.org/getieee802/download/802.11-2012.pdf (Chapter 10.2 Power management) and look at ral(4) (rt2860.c), athn(4), and acx(4) for example code. There are chips that ath(4) should support but does not. See http://marc.info/?l=openbsd-miscm=134901419419278w=2 There are chips that athn(4) should support but does not. I'm already working on AR9485 and could use some help there if you have access to such hardware. The equivalent Linux driver is ath9k which supports several models athn(4) lacks support for. Adding support for any of these would be great. ipw(4) is buggy: http://marc.info/?l=openbsd-miscm=134929439329011w=2 Could also be a hardware/firmware issues. Needs research. urtwn(4) is buggy: http://marc.info/?l=openbsd-miscm=134666785524449w=2 http://marc.info/?l=openbsd-miscm=134666785524449w=2 This could also be a problem in the USB stack, not sure. Needs research. There is no driver for BCM43228 chips. There is a BSD-licensed driver for linux: http://linuxwireless.org/en/users/Drivers/brcm80211 Writing a driver for this will be very difficult! I'm mentioning this for completeness. FreeBSD has a driver for some other broadcom chips we don't support: http://svnweb.freebsd.org/base/head/sys/dev/bwn/ It would be nice (but far from trivial) to get this ported to OpenBSD. Of course, it's best to start off hacking on drivers for hardware you own and actually use. IPv6: Carp does not support unicast peers over IPv6, only multicast. Support for IPv4 unicast was added by reyk in this commit: http://marc.info/?l=openbsd-cvsm=121348006024130w=2 The equivalent should be implemented for IPv6. ospf6d(4) does not support multiple areas as specified in RFC 5340 and thus isn't really RFC-compliant. Also, it does not support virtual links (same RFC). ospf6d(4) does not support authenticated OSPF packets. It should be using IPsec for this, according to RFC 5340 (the MD5-based approach used in OSPF for IPv4 is not applicable to OSFP for IPv6). Currently we require users to manually configure IPsec flows between routers. It would be great if there was a way to tell ospf6d to configure ipsec flows automatically. Obviously, IPsec secrets would need to be installed on any routers taking part in the OSPF network, but beyond that ospf6d should just do whatever is necessary to secure OSPF traffic. I hope this list helps you getting started. If you have any questions just let me know.

I want to be able to walk to the coffee shop, mail a Christmas card to my aunt Sarah, buy a cup of coffee, go to the library, and look at pictures of Iceland, and then come home and not find advertizements in my mail box saying my aunt Sarah likes Acme Brand Coffee, and travel brochures for Iceland; but on the internet we know today, this is the level of privacy we have (none). And why do we have this lack of privacy? To make other people money. As the Tor developers put it, there is an arms race between censorship and data collection, and freedom and privacy. I am using my skill-set to help others make it more difficult to take my freedom and privacy away.
