Thanks. Len Zaifman If you use the lsusb command from the usbutils package on this device you can check its USB descriptors. Look for: AudioControl Interface Descriptor: bLength 9 bDescriptorType36 bDescriptorSubtype 1 (HEADER) bcdADC 1.00 If bcdADC says something other than 1.00, I think you're out-of-luck. I suspect it reads 2.00. AFAICT Universal Serial Bus Device Class Definition for Audio Devices Release 2.0 isn't supported by OpenBSD. Unless someone else has a better solution, quite likely the uaudio driver will need somebody able to update it for your device to work.
Thinkpad x220i hangs after a few days of uptime
Hello, i am using a Thinpad x220i and I have a weired problem. Most of the time, i just put my notebook into suspend mode (zzz), so, I do not often reboot. After 4 or 5 days, my notebook suddenly stops and I can't do anything except pressing the power button for 4 or 5 seconds and reboot. Sadly enough, there are no hints in the log files. Is there a way to track this problem down somehow? I really want to help and provide better information, but for now, I can only give you a dmesg (below). Software I am running is firefox, xombrero, emacs, tmux and multiple shells, wmaker (+ a few dockapps), music with mplayer and xmms2.

Live usb stick quite slow
Hi misc, I have installed OpenBSD on an USB stick (a Kingston DataTraveler G3). Nevertheless, the system is quite slow... For example, I recently install firefox or, more precisely, those packages: at-spi2-atk-2.8.1.tgz at-spi2-core-2.8.0.tgz dbus-glib-0.100.2v0.tgz dconf-0.16.1.tgz firefox-22.0.tgz flac-1.3.0p0.tgz gconf2-3.2.6p0.tgz glib2-networking-2.36.2.tgz gnutls-3.2.1.tgz gsettings-desktop-schemas-3.8.2.tgz gstreamer-0.10.36p5.tgz gstreamer-plugins-base-0.10.36p6.tgz gstreamer-plugins-good-0.10.31p7v0.tgz gtk+3-3.8.2p3.tgz gvfs-1.16.3.tgz libarchive-3.0.4p0.tgz libnettle-2.7.1.tgz libsecret-0.14p0.tgz libshout-2.2.2p2.tgz libsoup-2.42.2.tgz libsoup-gnome-2.42.2.tgz libtasn1-3.3.tgz p11-kit-0.18.3p0.tgz taglib-1.8p5.tgz tremor-20120410p0.tgz wavpack-4.60.1p0.tgz which have a total size of 67Mo and it tooks ~17min to finish. If I compute correctly, this give me an average of ~67ko/sec which, I think, is quite bad. I precise that I download and store all the packages on an mfs partition, so this is really the time consumed to install them. Also, all the partitions are mounted with the softdep and the noatime options. Is this normal ? Did I make any mistakes in the organisation of the system on the stick ? Is there something I can do to improve the performance of the I/O ? Below, you will find the output of the fdisk, disklabel, usbdevs and dmesg commands.

OpenBGPd match clause with multihop BGP session
Hi,
I'm using cymru[1] bogon feed onto a router receiving several full tables.
On this router I have:
neighbor $CYMRU_PEER_v4 {
descr cymru-fullbogon-v4-001
local-address $NERIM_MY_v4
max-prefix 9550 restart 10
}
bgpctl show rib correctly shows the prefixes being added with nexthop
$CYMRU_PEER_v4
This nexthop however is invalid (because I can't reach it directly),
which doesn't matter to me since this traffic should be blackholed
anyway.
To blackhole this traffic I use:
match from group cymru_bogons set nexthop blackhole
The traffic never gets blackholedunless I use
set nexthop $NERIM_PEER_v4
in the neighbor stanza.
Is it a normal behavior, a misunderstanding on my side, or a bug ?
Thanks
Laurent
PS:
$CYMRU_PEER_v4 = IPv4 address of the cymru router
$NERIM_MY_v4 = my public IPv4 address
$NERIM_PEER_v4 = my IPv4 gateway (ISP side)

Single process needing a lot of memory
Hi all First of all, sorry for the kind on newbie question. I'm running some memory-heavy statistical analyses using R, which require more memory than what's physically available. I.e. the machine (a x201, which is running -current amd64) has 4Gb of physical mem, but R needs at least 6Gb. If I understand correctly, this is what virtual mem is there for, but -- and here's the newbie part -- I'm not quite sure on how to make it work. Steps taken so far: 1. Raise datasize-cur and datasize-max to 3G. Everything runs OK, but R complains about not being able to allocate enough mem (expected). 2. datasize-cur=3G + datasize-max=3G + vmemoryuse=4G (swap partition has 5G). Everything runs OK, but R complains about not being able to allocate enough mem. systat swap shows absolutely no change. 3. vmemoryuse=3G + datasize-max=infinity Admittedly not knowing what I was doing. Big time SNAFU. Everything slows to a crawl when memory usage goes past the available phys mem (about 3.6G). And by a crawl I mean unusable if using X, requiring great patience if on virtual consoles. top shows R using over 1000% (not a typo) CPU although the CPU summary lines say they're all idling. state is run/3, wait column says pagerse. Swap usage increases, though. R never gets back to a usable state. Clue bat required. Is there anything else that needs to be done to enable R to (properly) use some of the virtual memory?

Some network drivers are notably flaky when some timeouts occur, I've managed to lose iwn and re due to delays related to excessive swapping.
Relayd with dsr and sticky-address
Hello,
i try to set up a load balancing machine for internal use. We have 2
webservers serving a web-app. This application depends on sticky clients,
because it is using sessions w/o session replication. I try to set up a dsr
environment, which is working perfectly at first glance.
I set the
set timeout src.track 3600
in my pf.conf, but the source tracking entries in pf only shows with:
10.66.66.2 route-to 10.243.10.4 ( states 0, connections 0, rate 0.0/0s )
age 00:00:01, expires in 00:00:00, 0 pkts, 0 bytes, rule 0
It expires with the next timeout interval which is 10s (default).
This ends in a stickyness of my clients only while their tcp-connection is
alive + (max 10s).
Is there a way to increase this by relayd.conf or by setting magic timeouts in
pf.conf?
my pf.conf:
set limit states 10
set skip on lo
set timeout src.track 3600
anchor relayd/*
pass in

This is a loadbalancing only set up. So we do not need the security of pf in
this case. We also need the dsr, because the routing from the server to the
client is asynchronous or in some cases the clients are on the same local
network like the balanced servers.

IPv6 static routing to a different subnet
Hi list, i have a difficult time reaching my default IPv6 default gateway in a different subnet. Asking Google brought up some threads from early 2011. Most of the solutions where switching the prefixlen to reach the gateway but this didn't work out for me. The mentioned route commands didn't work out for me, too. The support said, as they don't provide OpenBSD on their machines, they don't support it. They told me, to set up one IP from my network and add a host route to the gateway. My network is 2001:4ba0::00ab::0 /64 The gateway is 2001:4ba0::1:beef::1 The provided example for FreeBSD (not verfied): route add -inet6 [ipv6-gateway] -iface [interface] ndp -s [ipv6-gateway] [mac-gateway] route add -inet6 default [ipv6-gateway] The provided example for Linux (verfied with provided rescue console): ~ # ip -6 route add 2001:4ba0::1:beef::1 dev eth0 ~ # ip -6 route add default via 2001:4ba0::1:beef::1 ~ # ip -6 route show 2001:4ba0::1:beef::1 dev eth0 metric 1024 2001:4ba0::ab::/64 dev eth0 proto kernel metric 256 fe80::/64 dev eth0 proto kernel metric 256 default via 2001:4ba0::1:beef::1 dev eth0 metric 1024 ~ # ping6 ipv6.google.com PING ipv6.google.com(la-in-x6a.1e100.net) 56 data bytes 64 bytes from la-in-x6a.1e100.net: icmp_seq=1 ttl=54 time=39.5 ms 64 bytes from la-in-x6a.1e100.net: icmp_seq=2 ttl=54 time=39.3 ms 64 bytes from la-in-x6a.1e100.net: icmp_seq=3 ttl=54 time=38.8 ms 64 bytes from la-in-x6a.1e100.net: icmp_seq=4 ttl=54 time=39.1 ms ^C That's what i did on OpenBSD: ~ # ifconfig em0 inet6 2001:4ba0::ab::1 prefixlen 64 ~ # ifconfig em0 em0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500 lladdr 00:25:90:e0:20:c6 priority: 0 groups: egress media: Ethernet autoselect (1000baseT full-duplex,rxpause,txpause) status: active inet 217.79.184.47 netmask 0xff80 broadcast 217.79.184.127 inet6 fe80::225:90ff:fee0:20c6%em0 prefixlen 64 scopeid 0x1 inet6 2001:4ba0::ab::1 prefixlen 64 ~ # route add -inet6 -iface -ifp em0 -host 2001:4ba0::1:beef::1 \ -prefixlen 64 2001:4ba0::ab::1 add host 2001:4ba0::1:beef::1: gateway 2001:4ba0::ab::1 ~ # route add -inet6 default 2001:4ba0::1:beef::1 add net default: gateway 2001:4ba0::1:beef::1 ~ # route -n show -inet6 Routing tables Internet6: DestinationGatewayFlags Refs Use Mtu Prio Iface ::/104 ::1UGRS 00 - 8 lo0 ::/96 ::1UGRS 00 - 8 lo0 default2001:4ba0::1:beef::1UGS 00 - 8 em0 ::1::1UH 140 33144 4 lo0 ::127.0.0.0/104::1UGRS 00 - 8 lo0 ::224.0.0.0/100::1UGRS 00 - 8 lo0 ::255.0.0.0/104::1UGRS 00 - 8 lo0 :::0.0.0.0/96 ::1UGRS 00 - 8 lo0 2001:4ba0::1:beef::12001:4ba0::ab::1UHS 10 - 8 em0 2001:4ba0::ab::/64 link#1 UC 00 - 4 em0 2001:4ba0::ab::1 00:25:90:e0:20:c6 HL 00 - 4 lo0 2002::/24 ::1UGRS 00 - 8 lo0 2002:7f00::/24 ::1UGRS 00 - 8 lo0 2002:e000::/20 ::1UGRS 00 - 8 lo0 2002:ff00::/24 ::1UGRS 00 - 8 lo0 fe80::/10 ::1UGRS 00 - 8 lo0 fe80::%em0/64 link#1 UC 00 - 4 em0 fe80::225:90ff:fee0:20c6%em0 00:25:90:e0:20:c6 HL 00 - 4 lo0 fe80::%lo0/64 fe80::1%lo0U 00 - 4 lo0 fe80::1%lo0link#4 UHL 00 - 4 lo0 fec0::/10 ::1UGRS 00 - 8 lo0 ff01::/16 ::1UGRS 00 - 8 lo0 ff01::%em0/32 link#1 UC 00 - 4 em0 ff01::%lo0/32 fe80::1%lo0UC 00 - 4 lo0 ff02::/16 ::1
Relayd with dsr and sticky-address
Sorry, i forgot to mention my version 5.4
Hello,
i try to set up a load balancing machine for internal use. We have 2
webservers serving a web-app. This application depends on sticky clients,
because it is using sessions w/o session replication. I try to set up a dsr
environment, which is working perfectly at first glance.
I set the
set timeout src.track 3600
in my pf.conf, but the source tracking entries in pf only shows with:
10.66.66.2 route-to 10.243.10.4 ( states 0, connections 0, rate 0.0/0s )
age 00:00:01, expires in 00:00:00, 0 pkts, 0 bytes, rule 0
It expires with the next timeout interval which is 10s (default).
This ends in a stickyness of my clients only while their tcp-connection is
alive + (max 10s).
Is there a way to increase this by relayd.conf or by setting magic timeouts in
pf.conf?
my pf.conf:
set limit states 10
set skip on lo
set timeout src.track 3600
anchor relayd/*
pass in
pass out
my relayd.conf:
table web { 10.243.10.4 10.243.11.4 }
redirect nagios {
listen on 10.244.2.199 port 80
sticky-address
session timeout 3600
route to web mode least-states check tcp interface vlan243
}
This is a loadbalancing only set up. So we do not need the security of pf in
this case. We also need the dsr, because the routing from the server to the
client is asynchronous or in some cases the clients are on the same local
network like the balanced servers.

Re: Single process needing a lot of memory
Nevertheless, things ought to work slightly better. I still consider network driver failing due to swap to be a bug in the driver. It should lock down memory if it's necessary. Or there is something in the bufcache swap routines or some disk driver that locks other users for inordinately long periods, especially wrt interrupts. A machine that doesn't run out of swap should work. Not be very responsive, that's fine. Having a network driver that downright FAILS because of that is a bug.

My network is 2001:4ba0::00ab::0 /64 The gateway is 2001:4ba0::1:beef::1 Your provider has a stupid network. There are way more than enough to allocate an entire /64 just to route your real /64 to as e.g. HE's tunnelbroker.net does. The provided example for FreeBSD (not verfied): route add -inet6 [ipv6-gateway] -iface [interface] ndp -s [ipv6-gateway] [mac-gateway] route add -inet6 default [ipv6-gateway] This hints at the correct thing to do. Your gateway's public IP address isn't on your network, but you share a link-local address. Run ifconfig em0 inet6 2001:4ba0::00ab:: prefixlen 64 route add -inet6 default [link-local address of gateway] The link local address of the gateway looks like fe80::dead:beef:cafe:babe%em0. You may be able to get it from ndp -a or tcpdump, but you can ask the provider if all else fails. From the example above, you have the MAC address. I believe there are also several converters online, or it's in RFC 4291. This is easier than messing around with -iface because IPv6's NDP won't recognize that. Since with IPv6 you get an entire network, it would be beneficial if your provider didn't have to use one for their router. The usual solution is to allocate a /64 for their router and your endpoint, and then route your network to your endpoint. You have the same thing, except the point-to-point link is using link-local instead of global addresses. - Martin

ldapd alias dereferencing
Hi list, I am attempting to replace openldap-server with ldapd. While poking around I noticed that alias dereferencing does not work in ldapd. I tested with ldapsearch, with '-a always' to enforce dereferencing. This works as expected (the referenced object is returned) on openldap, but not at all on ldapd. Am I doing something wrong or is this just not implemented (yet)?

Thanks for your time and for the detailed explanation (as you always do, which is great). I am well aware that swapping is crap (and why), especially in this particular case. I just didn't expect it to go so bad. The OP was just because I wasn't sure if I was doing things right. I saw the system practically freeze in a weird way (HD activity but frozen display, switching virtual consoles but no typing, etc), which was unexpected and made me wonder what the hell was going on. I've also run the same analysis on a mac also with 4Gb RAM running OS X (i.e. swapping), and it worked out nicely, so I thought it could be done here as well (and before the flames come out, *I know* that's comparing apples and oranges (no pun intended), and that there's little more than similar hardware between the two systems). I'll just get the right tool for the job: some more RAM. It'll make the RAM usage % indicator on my dwm desktop even more fun to look at. Cheers Zé --

People who don't know the real history are doomed to repeat it without even realizing it. The 8088 CPU in the original PC, which was designed and built by IBM before MS was involved, had a 20 bit physical address space. That's one megabyte. So the most RAM the PC ever could have supported was 1MB, not so very much more than 640KB. But then out of that 1MB you have to carve out some space for things like the BIOS and the video card (and sound card, and network, and ISA whatever). So the engineers at IBM said that the top 384K of the address space would be wired up to peripherals instead of RAM, leaving 640K. It's a hardware limitation, not one of software. OpenBSD doesn't use that 384K either. And it's not a limitation that only happened once. If you stick 4GB of RAM into your PC and boot OpenBSD i386, you'll see that you only get about 3GB. Basically the same thing. Space has been reserved for peripherals, so you don't get to use the RAM in that space. If you boot amd64, you'll get to use it because the memory is remapped higher up, above 4GB. (And if you bought a 80386 and booted 32-bit Windows, you got to use the memory above 640K too). Nobody ever proclaims 3GB of RAM will be enough for everybody! -- random dude at Intel, but that's exactly what happened. The same mistake was repeated. And then came the various workarounds like PAE, just like there were workarounds like expanded memory in the DOS days. For that matter, nobody ever says 80 bytes of memory will be enough for everybody! -- John Mauchly (ENIAC) There's a lesson in there about foreseeing future requirements, but there's also a lesson that should be learned about real world products being subject to real world constraints. You go to market with the CPU architecture you have, not the CPU architecture you want. I'm reminded of Bjarne Stroustrup's comment about there being languages people like and languages people use.

Re: IPv6 static routing to a different subnet

Asking Google brought up some threads from early 2011. Most of the solutions where switching the prefixlen to reach the gateway but this didn't work out for me. The mentioned route commands didn't work out for me, too. The support said, as they don't provide OpenBSD on their machines, they don't support it. They told me, to set up one IP from my network and add a host route to the gateway. My network is 2001:4ba0::00ab::0 /64 The gateway is 2001:4ba0::1:beef::1 Your provider has a stupid network. There are way more than enough to allocate an entire /64 just to route your real /64 to as e.g. HE's tunnelbroker.net does. The provided example for FreeBSD (not verfied): route add -inet6 [ipv6-gateway] -iface [interface] ndp -s [ipv6-gateway] [mac-gateway] route add -inet6 default [ipv6-gateway] This hints at the correct thing to do. Your gateway's public IP address isn't on your network, but you share a link-local address. Run ifconfig em0 inet6 2001:4ba0::00ab:: prefixlen 64 route add -inet6 default [link-local address of gateway] The link local address of the gateway looks like fe80::dead:beef:cafe:babe%em0. You may be able to get it from ndp -a or tcpdump, but you can ask the provider if all else fails. From the example above, you have the MAC address. I believe there are also several converters online, or it's in RFC 4291. This is easier than messing around with -iface because IPv6's NDP won't recognize that. The provider won't tell me, already tried that, some sort of ;). ndp -a doesn't show any interfaces beside the one from the server itself: ~ # ndp -a Neighbor Linklayer Address Netif Expire S Flags malkier.mpeters.org 0:25:90:e0:20:c6 em0 permanent R fe80::225:90ff:fee0:20c6%em0 0:25:90:e0:20:c6 em0 permanent R fe80::1%lo0 (incomplete) lo0 permanent R With tpcdump there is only one other link local address sending to multicast addresses. This link local address is strange, though. It is not a converted one from the original mac address, which the provider provides as mac address from the gateway (00:0c:db:51:45:00) nor from the mac address, which shows up after adding the one as link local gateway in ndp: ~ # ndp -a Neighbor Linklayer Address Netif Expire S Flags malkier.mpeters.org 0:25:90:e0:20:c6 em0 permanent R fe80::225:90ff:fee0:20c6%em0 0:25:90:e0:20:c6 em0 permanent R /fe80::d555:905d:9f64:da3d%em00:25:90:c7:a7:2 em0 23h57m23s S / fe80::1%lo0 (incomplete) lo0 permanent R I tried both link local addresses, just to be sure (fe80::d555:905d:9f64:da3d%em0 which showed up in the tcpdump and the generated one from the mac provided fe80::20c:dbff:fe51:4500%em0). Neither worked. Later one showed no mac in ndp: ~ # ndp -a Neighbor Linklayer Address Netif Expire S Flags malkier.mpeters.org 0:25:90:e0:20:c6 em0 permanent R fe80::20c:dbff:fe51:4500%em0 (incomplete) em0 1sI 3 fe80::225:90ff:fee0:20c6%em0 0:25:90:e0:20:c6 em0 permanent R fe80::1%lo0 (incomplete) lo0 permanent R What i don't really get, is that's working with the other system, but not with OpenBSD when it is set up in a similar way :( Marc Since with IPv6 you get an entire network, it would be beneficial if your provider didn't have to use one for their router. The usual solution is to allocate a /64 for their router and your endpoint, and then route your network to your endpoint. You have the same thing, except the point-to-point link is using link-local instead of global addresses. - Martin

More war stories: - At Interactive Data Corp., with the technical people coming largely from the MIT Lincoln Lab and IBM Cambridge, we ran a time-shared stock-screening service on IBM 360/67s running CP/CMS. CP created virtual 360s, accurate enough to run OS/360 (I'm not positive of this, but CP may have been the earliest system to create virtual machines on which you could run a full-blown OS, ala VMWare or QEMU). We ran this service initially on a 360/67 with 256KB of memory (the memory unit was the size of at least two refrigerators). - I don't recall if anyone famous said it, but we certainly thought that the 18-bits of (36-bit word) address space on the PDP-10 would be enough for a very long time, maybe forever. - There's an entertaining talk by Bob Kahn (I'll have to do a little digging to find it), one of the key visionaries behind the Internet (TCP/IP was originally called the Kahn-Cerf Protocol) about how they thought 32-bit IP addresses would be fine for a very long time. Six months later, Bob Metcalfe's little invention, Ethernet, became public, and Kahn realized that their thinking about address space, based on the handful of networks that existed when IP was designed, was wrong. They bought time by defining network classes that carved up the 32 bits in different ways, but they knew then, post-Ethernet, that 32 bits wasn't going to suffice. -- Jeff Simmons jsimm...@goblin.punk.net Simmons Consulting - Network Engineering, Administration, Security You guys, I don't hear any noise.

(5.4-i386) framebuffer console
I noticed on [The OpenBSD 5.4 Release](http://www.openbsd.org/54.html) wsdisplay(4) now attaches to inteldrm(4) and provides a framebuffer console. drm supports the radeon driver and I have an old Thinkpad T60 with: vga1 at pci1 dev 0 function 0 ATI Radeon Mobility X1300 M52-64 rev 0x00 radeondrm0 at vga1: apic 1 int 16 Cool. So I guess setting up a framebuffer console at 1024x768 might go something like this: wsfontload clueless wsconscfg -dF 5 wsconscfg -f /dev/drm0 -e vt100 -t hmm 5 Yeah, this needs a little work. Has anyone managed to pull this off?
