I have to verify if it always stops if pltime reaches zero.


It doesn't always stop immediately if pltime reaches zero and a new 
temporary address is generated. Only sometimes. But in the long run it 
eventually will fail and never recover.


It has to be a NDP problem. I'm not sure who is at fault. My guess would 
be the router, because its traces will start outputting a 
xx:xx:xx:xx:xx:xx mac address (that is not me anonymizing it):


(fd00:172:17:174:d468:28ab:498e:5d0e is the new autoconf temporary 
address on the OpenBSD host.)

I just don't get why Linux and Windows don't have the same problem. I 
try to collect more tcpdump and log-data.

Are you sure that the router had a valid NDP entry for
fd00:172:17:170:c57c:a20c:2d74:124 at this point?



The router doesn't have a valid NDP entry. It has a NDP entry for an 
address ifconfig says is deprecated. If I force the use of this 
deprecated address with "ping -I" the response are received.

Re: IPv6 ULA routing stops working after 20 hours or so

[Thomas Bohl]

Maybe I should let slaacd run in the foreground till IPv6 stops working 
and see if that give out clues.


The output of slaacd looks completely normal. Like this over and over again:

I also dug into the debug output of my router.
Echo request goes out, reply comes back and is routed/forwarded to the 
OpenBSD host.

Re: IPv6 ULA routing stops working after 20 hours or so

[Thomas Bohl]

Sorry for top post.

Are you doing any filtering of ICMP6 with PF?


I don't think so, it is the standard rule set:

# pfctl -s rules
block return all
pass all flags S/SA
block return in on ! lo0 proto tcp from any to any port 6000:6010
block return out log proto tcp all user = 55
block return out log proto udp all user = 55



I assume your router is also doing rad to hand out slaac to clients?


The router is doing router advertisements and slaacd handels it on the 
OpenBSD side.

IPv6 ULA routing stops working after 20 hours or so

[Thomas Bohl]

Hello,

I'm using ULAs for my local IPv6 networks. The hosts have internet 
access via the router doing NPTv6.

hosts usually helps. In rare cases a double restart is required. Linux 
and Windows don't show this problem.

I don't have a perfect solution for this, but being in a similar
situation with my hardware, I've grown accustomed to keeping the
USB audio plugged, and only plugging in the camera when I need it;
therefore generally *after* the audio-only device. This way the USB
audio device is always rsnd/1 here. This may not be what you're looking
for... there are also USB hubs with physical on-off switches that I've
used for my USB camera this way. YMMV

There are some who use their webcam with chromium frequently, including me.
It's been a few weeks but I just tested it and it still works on -current.
So if yours isn't working, it's either the configuration or your hardware...

While I'm not familiar with your specific device, it's clearly detected and
attaches to video0.

In terms of configuration, you need to have kern.video.record enabled (see
FAQ) and the device /dev/video0 needs to be owned by your user (also FAQ).
If you made any prior changes, you want to make sure that /dev/video is
still a symlink to video0 and not something else.

I think in chromium, you might need ENABLE_WASM=1 for many video conferencing
web pages.

This looks to me like you are chasing down a new rabbit hole every time
I open one of your emails. I'd suggest you take a step back from all
the stuff you seem to be trying without having a firm grasp on how to
observe or report reproducibility. Have you tried out sthen@'s advice
to check old kernels + snapshots[1]? I may have missed your response to
this. You wrote that you rarely got the issue prior 17-May-2024? If
that *is correct*, then you should be able to bisect using the snapshot
archive around what date things change.

I am highlighting *is correct* above because your issue seems to be
unpredictable enough that a few minutes of testing don't mean anything.
I suggest you try to find a *clear difference*, meaning between a
snapshot where no reboot happens for ideally a whole day of use, and
the next one where it clearly happens very quickly (and reproducible
at least a second or third time).

Your reports also make me wonder how much customization you are
running. You've mentioned at least compiling custom kernels and
setting bsd.re-config. It's easy to find yourself in virtually
unsolvable scenarios by configuring too much. It might be best to try
a clean install, ideally without activating xenodm/X11.

Never mind, I forgot to check this mailing list and read that I needed to put 
the source address on this line:
pass in log on wg0 inet from wg0:network to !wg0:network route-to IP_GATEWAY

I suppose that then the oddity is that this works with wg1 and may be a corner 
case of the wireguard interface as it's assigned xxx.xxx.xxx.xxx/32 by the VPN 
provider and so destination address = source address?

One side question as I consider using rdomain. man 4 rdomain gives as an 
example:
A pf.conf(5) snippet to block incoming port 80, and nat-to and move to
rtable 0 on interface em1:
   block in on rdomain 4 proto tcp to any port 80
   match out on rdomain 4 to !$internal_net nat-to (em1) rtable 0

Should it not be "match in" in the 2nd line? man 5 pf.conf reads:
rtable number
 Used to select an alternate routing table for the routing lookup.
 Only effective before the route lookup happened, i.e. when
 filtering inbound.
Or does it work because it's a match statement? 

Thanks all,

Issue with pf route-to and routing tables

[Thomas]

Hi all,

I'm greatly enjoying OpenBSD and have it on most of my devices as I try to set 
up my "perfect lab". I would like some feedback / thoughts about one behaviour 
which I don't quite get. 

I have a VM for the world facing side of my network. I have a wireguard network 
to link it up to a home router and other devices. My wireguard traffic is 
coming onto my VM through wg0. 

On my home router, I'm redirecting all wifi traffic to wg0 using the routing 
tables like so:
default192.168.0.1   wg0
IP_VM IP_Gatewaybse0
192.168.0.1  wg0 wg0

And natting outbound traffic on wg0 like so:
pass out on wg0 from $int_if:network nat-to wg0

I wanted to try out using route-to on my VM instead of using different rdomain 
or just to try something else. I have another wireguard tunnel, wg1 to relay my 
internal traffic further. 

I did not touch the routing tables at all and have something like:
pass in on wg0 inet from wg0:network to !wg0:network route-to wg1
pass out on wg1 nat-to wg1

Works like a charm. Now what I don't get is that for troubleshooting purposes, 
I needed to send some traffic to the world on my VM (instead of onward through 
wg1) and I initially tried:
pass in log on wg0 inet from wg0:network to !wg0:network route-to vio0
pass out log on $vio0 nat-to $vio0

Routing tables:
default   IP_Gateway   vio0
_Gateway MAC_Gateway  vio0

But this does not work. Removing "route-to vio0" does work, eg.
pass in log on wg0 inet from wg0:network to !wg0:network #route-to vio0
pass out log on vio0 nat-to vio0

I'm guessing that this may have to be since it's routed "twice"? Eg. routed-to 
and a second time with the default route of the routing tables? So I understand 
why route-to is not necessary in this case, but I would think route-to should 
still work and that means I don't get how it's working? I've tried used pflog0 
to check the above rules but cannot see any difference: in both cases, it's 
passing in on wg0 through vio0 and src IP is rewritten to VM public IP.

I'm thinking of more complex rules to split traffic from wg0 between wg1 and 
vio0 based on the ports and using route-to vio0 seemed the easiest way to do so.

Thanks in advance,

Thomas

This will likely break things. You would be effectively mixing an
almost-7.5 base with 7.4 packages. The solution is to point at the
snapshots packages directory, which is what -Dsnap does for you.

Re: Automatic OS updates

[Thomas Schmidt]

OP did indeed mean `sysupgrade`, but fwiw, `syspatch && reboot` reboots
your system if a patch as applied. I got it in all of my servers'
cronjobs.

Maybe you meant “syspatch” there?

Syspatching via cron is questionable - Some of the patches wont be loaded until 
the box is rebooted.

I think its better to run either syspatch or sysupgrade when i’m in front of 
the console and can deal with consequences.

you can select which audio device is used with -f/-F flags to sndiod

Re: OBS-Studio 26.1.0 and later

So you were using OBS-Studio in the past but can't remember how you
installed it?  As has been shown by others there never was a package for
7.1.  And then you blame the project for removing a package that was never
there in the first place.  Wow.

And you're also totally confusing some OS support with a full
implementation.

Use of fw_update to bootstrap OBSD

[Thomas]

Hello,

I am installing OpenBSD on an old xps13 9380. The WiFi is not supported and so 
I am using a usb dongle for which I need the athn-firmware. I get it to work 
and now wanting to prep a USB disk with all necessary firmware. I'm following 
the FAQ#4 on the website (I suppose it works with more firmware than just the 
WiFi).

So, now to my question. Using fw_update -F to the current dir does download all 
firmware (5 files) and SHA256.sig. However, the file SHA256.sig does not 
include the signature, using signify like so: 

signify -Cp /etc/signify/openbsd-73-fw.pub -x SHA256.sig *

Fails with message: invalid comment in SHA256.sig; must start with 'untrusted 
comment: '

Downloading the SHA256.sig from firmware.openbsd.org/firmware/7.3/SHA256.sig 
which includes the signature does work.

Is it that normal behaviour? Since the firmware.openbsd.org site is not HTTPS, 
and that, at least for me, fw_update does not download signed SHA256.sig, would 
it not be possible to download unintended files?

Thanks in advance,

Thomas

Looks like Comte followed the console instructions at [1] to the letter.
It seems to me that jumping right to ffplay recording isn't the best
way for you to check the camera is working. Simplest way to test seems
to me:

$ video -f /dev/video0

And then you should see a window with the video stream...

The obvious question that I have right off the bat is what is in your

xfce is in there would be a start.

I don't think that command tells you anything about the installation
status of that package. When I need to check if a package is installed,
I use for example:

$ pkg_info | grep "gtk.doc"

>From pkg_info(1):

"If no pkg-name is specified, pkg_info shows the names and one-line

I'm not sure that that's the command to answer the question that you
have. In fact, with wc -l: 14274 this is an exceptionally noisy command
and it shows dozens if not hundreds of different packages that install
into share/gtk-doc.

Note that pkg_locate doesn't limit itself to what you have currently
installed, but shows any file from any package, installed or not, that
has the string 'share/gtk-doc' in its path.

I think that's asking for trouble and sometimes hard-to-diagnose bugs
with packages in the future.

I'm still not sure what problem you are trying to solve... You want to
upgrade, but are afraid of having too little space in the /usr
partition?

Frankly, having /usr/local on its own partition is exactly the kind of
default that would protect you from /usr/local/share/gtk-docs impinging
on your space in the /usr partition... Not sure if that problem
situation isn't entirely self-made and you are looking for solving the
problems of unsupported customization with even more unsupported
customization...

Even if there was an implementation written, patents are involved (use is

You might get some replies if you rewrote that email quite a bit more
succinctly.   E.g. retain the steps taken along with the results, then
delete irrelevant paragraphs, delete redundancies, delete assumptions,
delete info about other OSes that has nothing to OpenBSD, that will make it

It doesn't.  But it also doesn't mention many desktop environments and

That being said I clearly haven't kept up with KDE development so I went

I have noticed tmux locking up with my original tmux.conf when closing
windows, likely because of renumber-windows on:

set-option -g default-terminal "tmux-256color"
set-option -g history-limit 3000
set-option -g renumber-windows on
set-option -ag window-status-current-style bold
set-option -ag window-status-current-style fg=black
set-option -ag window-status-current-style bg=blue
set-option -ag status-style bg=cyan
set-option -g escape-time 50

I have since switched to a more simplistic config that hasn't run into
the lock up, but I can still trigger it with movew -r as described
above:

set-option -g escape-time 50
set-option -g base-index 1
set-option -g pane-base-index 1

Re: iked server/client OBSD/OBSD

[Thomas Bohl]

Questions about cert for roadwarrior and more? Why 192.168.1.79? i was
expecting 10.0.5.x please.


Why did you expect that?



spi=0xc166e8f236679cc9: recv IKE_SA_INIT res 0 peer 45.77.223.7:500 local
192.168.1.79:500, 255 bytes, policy 'roadwarrior'


192.168.1.79 is your local IP, which is on the interface with a link to 
the default gateway.


$ route -n show -inet


If you have multiple IPs and you want to force iked to use a specific 
one, you have to use "local":


local 10.0.5.x peer 45.77.223.7 \



spi=0xaf891eb37dd8f4cc: ca_getreq: no valid local certificate found for
FQDN/roadwarrior
spi=0xaf891eb37dd8f4cc: ca_getreq: using local public key of type RSA_KEY
spi=0xaf891eb37dd8f4cc: send IKE_AUTH req 1 peer 45.77.223.7:4500 local
192.168.1.79:4500, 947 bytes, NAT-T

192.168.1.79:4500, 65 bytes, policy 'roadwarrior'
spi=0xaf891eb37dd8f4cc: sa_free: authentication failed notification from peer


Just a guess, since I have never worked with trusted public keys, but 
maybe you have to copy the clients local.pub it into

/etc/iked/pubkeys/fqdn/roadwarrior
(not /etc/iked/pubkeys/fqdn/roadwarrior/local.pub)
or
/etc/iked/pubkeys/ipv4/A.B.C.D

Re: APCI on old Thinkpad

[Thomas Vetere]

Yep, Claudio is correct. I have an old 600e and this is an official
statement from IBM support page long ago:

*"The ThinkPad 600E is ACPI ready. ACPI is not installed, but the system
hardware supports ACPI. While ACPI shows a great deal of promise for the
future, numerous problems affect the operation of ACPI on ThinkPad and
other notebook systems. Therefore, the system comes with Windows 98 running
in APM mode."*

So while it might 'support' ACPI theoretically, it probably wont work very
well ;)

tmux only possible as root and not as normal user in 7.3?

[Thomas Schnell]

Hi there,

I have three new installed machines, that show the same strange behaviour: tmux 
is only startable as root, if I want to start it with command "tmux" as normal 
user (which is in wheel group, btw), I get the error "no sessions", if I try to 
start it with command "tmux start-server", the error is "no server running on 
/tmp/tmux-1000/default".
On another machine, where OpenBSD has been installed and upgraded since version 
6.7, tmux starts without problems as said user.
I searched FAQ, manpages, www up and down and can not figure out, what goes 
wrong.
Is there anything I missed in manual or release notes? Was there any change in 
tmux startup?
Any hints would be highly appreciated!

thanks in advance

Re: build go projects with current: bad system call (core dumped)

[Thomas Huber]

This issue seems to be related to hardware limits eg. not enough RAM.
I came across these errors on a 1gig openbsd.amsterdam VM (thanks mischa
for your great service!!)
But all the mentioned go projects build fine on larger OpenBSD-VMs (eg.
4gig exoscale VM) and this builds run fine on the smaller VM.

Thanks Stuart for helping out again and verifying the build step.

build go projects with current: bad system call (core dumped)

[Thomas Huber]

Hi @misc,

I face a problem with -current when building golang projects.
This worked fine on 7.2 and I think it stopped working with 7.3 release.
Now I try it on -current.

I get the following error:
"go: error obtaining buildID for go tool compile: signal: bad system call
(core dumped)"

The Projects I´m trying to build are the nats-server[1] and natscli[2].
go version go1.20.4 openbsd/amd64

Maybe someone on this list has a clue...
Thanks Thomas (the u2k20 host)

Re: PC Engines APU platform EOL

[Thomas M. Beaudry]

Linux is slowly losing it's appeal for servers. IT is starting to notice
that Linux servers are cracked almost as much as Windows servers. A large
problem with any OS lacking a central authority to insure that nothing is
added before being fully verified as not introducing a vulnerability.

Re: Encrypted softraid - Operational question

[Thomas Bohl]

Hi

In a server with an encrypted root - server boots with key in USB stick, 
not passphrase.


Can I remove the USB stick with the key, after the server is up and 
running?


Yes



Will I have any problems doing that?


No. Though not at the moment, I used such a setup for years. Only 
inserting the stick for reboots.

Re: Help for another wiped out disklabel

Ok, now that 7.3 is up and running fine on sd0 I can re do my sd1 USB SSD.

This SSD was set up as a 2nd disk back when I originally installed 6.8 on
it so it's hard for me to remember how I would have had it start at 0
rather than 64 as mentioned in the FAQ.

Thanks for reading and reminding me Nick.

Help for another wiped out disklabel

[Greg Thomas]

I just ran through a fresh 7.3 install onto sd0 on an old 6.8 laptop and I
have no idea what happened to the disklabel on sd1 (during the install I
only did an automatic disklabel on sd0).  This is just a backup of my
current laptop so not the end of the world (unless my current laptop dies
before I have a chance to back it up again).

I was using the whole sd1 disk attached by USB for the backup and from what
I recall I had one big /dev/sd1a mounted on /backup.  Here's the current
disklabel.  The only thing I've tried is changing the boundstart from 2048
to 64, and then creating an a partition with offset of 2048 and 64.  No
luck there.  I'm foggy from getting through the end of a case of COVID so
let me know if there are some obvious parameters I should be using, or if
its futile.

And next time I'll disconnect the USB disk before doing a fresh install.

Thanks for reading.

Going out on a limb here, but this sounds an awful lot like your window
manager might error out and kick yo back to xenodm. I can't find LeftWM
in the ports - is that a self-compiled window manager?

Also can you specify what you mean by "the terminal". If you make it to
the xenodm login manager, you should be able to switch to the text
console with Ctrl+Alt+F1-F4. If that works, then you could log in there
and examine ~/.xsession-errors after a failed xenodm login to see what
error messages are produced.

Hello,

Any ideas / working config for a dynamic client hosting an iked on a VPS?


When using certificates I always use ASN1_DN for srcid and dstid. It 
should look something like this:


srcid "/C=DE/ST=Lower 
Saxony/L=Hanover/O=OpenBSD/OU=iked/CN=185.21.22.23/emailAddress=r...@openbsd.org 
" \
dstid "/C=DE/ST=Lower

\


(I have never used "ikectl ca", so I'm not sure what the files a called. 
But with something like this you should be able get the srcid/dstid-lines:

openssl x509 -subject -noout -in 185.21.22.23.crt
openssl x509 -subject -noout -in p7.local.crt)

Re: ikev2_resp_create_child_sa: no proposal chosen

[Thomas Bohl]

But the VPN-Router has a IKE-I-General-failure 0x21ff. All of the sudden 
it's a problem that I only want to route specific networks?! IPSec is so 
exhausting.


I got it working. The trick is to have iked send the CREATE_CHILD_SA 
request / initiate the rekeying first. Either by having lower 
ikelifetime and lifetime values than on the VPN-router, or by setting 
higher values on the VPN-router than the iked standards.


I configured iked with halved values my LANCOM router uses. This is 
stable over time as well as over bytes transferred.

Re: ikev2_resp_create_child_sa: no proposal chosen

[Thomas Bohl]

Thanks for your responses.


Try adding some non-modp2048 options. Maybe look at the SA installed
from the initial negotiation (ipsecctl -vvsa) for ideas.


I think this is the right answer. The log tells you what the other side sent:

spi=0x0a131729beeb819a: ikev2_log_proposal: ESP #1 ENCR=AES_CBC-256
spi=0x0a131729beeb819a: ikev2_log_proposal: ESP #1 INTEGR=HMAC_SHA2_256_128
spi=0x0a131729beeb819a: ikev2_log_proposal: ESP #1 INTEGR=HMAC_SHA1_96
spi=0x0a131729beeb819a: ikev2_log_proposal: ESP #1 ESN=NONE

There isn't any DH group for PFS here, so drop the modp2048 or add it on the
other side.


I tried countless different childsa lines, without success. Modp2048 
didn't show up because I deactivated PFS. I didn't knew this was 
correlated. Now it shows up:

ikev2_log_proposal: ESP #1 DH=MODP_2048

I than removed SHA1 and AES-CBC-256 from the IKE-/Child-SA hash/chiper 
list on the VPN-router. Having now only:

DH group: DH14 (MODP-2048)
PFS: Yes
IKE-/Child-SA: Chiper: AES-GCM-256, Hash: SHA-256
(Available settings are described here 
https://www.lancom-systems.com/docs/LCOS/Refmanual/EN/#topics/lanconfig_vpn_ikev2-ipsec_encryption.html 
)


And this line in iked.conf:
childsa enc aes-256-gcm group modp2048 \


At first it looks ok. iked reports:
spi=0xf3e9aaf0b7009e4e: recv CREATE_CHILD_SA req 0 peer 
88.14.XXX.YYY:4500 local 192.168.1.210:4500, 461 bytes, policy 'rathaus'

But the VPN-Router has a IKE-I-General-failure 0x21ff. All of the sudden

ikev2_resp_create_child_sa: no proposal chosen

[Thomas Bohl]

Hello,

I have several OpenBSD 7.2 connected to a commercial VPN-Router (LANCOM 
1781EW+) using iked. It works, except every time the Child SA 
negotiation starts, iked answers NO_PROPOSAL_CHOSEN to the router. Which 
leads to closed connections and a new IKE SA negotiation.

I don't understand this because the proposal looks supported to me.

crontab and /usr/local/{,s}bin

[Thomas L.]

hi,

what is the reason that /usr/local/{,s}bin is not in PATH in crontab?
this seems to be the case on all unix-like systems and it regularly
bites people. sometimes someone says it's for security w/o being
able to tell what is being prevented by this. or is it just some
historic default noone bothered to change?

kind regards,

thomas

Suggestion for improving FAQ14: UUIDs

[Thomas Dettbarn]

Hello!
 
tl;dr: I would like to suggest adding a line about the virtues of UUID to the 
FAQ14.
Something along the lines of "Remember to set up the UUID in
your /etc/fstab afterwards." or something.
 
 
The thing is, I have a RAID-5 setup in my system. One which I was able to set 
up, thanks to this one:
 
https://www.openbsd.org/faq/faq14.html
 
The entry in my /etc/fstab is now
 
/dev/sd7p /home ffs rw,nodev,nosuid 1 2
 
Which. Is. Stupid. I know: Yesterday, I wanted to boot my System, but I forgot 
to unplug a
USB-Device, which got mapped to sd7. So then I was unable to mount the /home. 
If I WOULD HAVE BEEN smarter, I would have used a UUID in my fstab.
 
Anyways, it is my believe that adding a line to each section might help the 
next person as
stupid as me, hence my suggestion.
 
 
Thomas

I was on an MS Teams meeting a few weeks ago with camera working. The
main issue from my experience was the web client auto disconnecting
after a while.

I've seen testing/preview camera output being just a black rectangle, but
it worked in the meeting itself.

I have package libv4l installed; not sure if that is involved.
Otherwise, would check that everything has been set up correctly -
correct permissions on /dev/video0 (rw), sysctl kern.video.record=1,
and chromium running with ENABLE_WASM=1 in the environment.

Do other browser-based video calls work? Can test for example with Zoom
here: https://zoom.us/test

That seems like a painful workaround; check the above if that helps
narrow down the problem.

Re: Configure OpenBSD for remote server rarely used

You should reboot whenever patches or upgrades require it.  Was that a
trick question or something?

Re: Locking network card configuration

[Thomas Bohl]

mac2dev() {
# This got long
ifconfig | while IFS= read _line; do
if [[ "$_line" = [a-z]!(\ *):* ]]; then
_dev=${_line%%:*}
elif [[ "$_line" = *lladdr*$1* && $_dev != vlan* ]]; then
echo $_dev
fi
done
}

_if=$(mac2dev "$_mac") # or just _if=$(mac2dev ${_hn#*.})


My solution would have been:

_if=`ifconfig | while read _line; do
[[ $_line == "lladdr "$_mac ]] && \
echo ${_lineabove%:*} && break
_lineabove=$_line
done`

I didn't know about vlan though.




Note that the vlan devices need to be excluded. Are there other
circumstances which could confuse this in ifconfig's output?

Re: Locking network card configuration

[Thomas Bohl]

Hello,


I suppose there is some argument that we should support hostname.MAC
files


Maybe a function in netstart right before vifscreate could be enough to 
achieve this? I creates this diff, against stable for now though, as a test.


Create a /etc/hostname.MAC file like you would create a /etc/hostname.if 
file. (MAC = lladdr as shown with ifconfig. Like 
/etc/hostname.08:00:27:14:26:0d)
/etc/netstart than creates a symbolic link to the corresponding 
hostname.if. If there is a hostname.if file it is not overwritten. The 
rest works the same.

Re: OpenIKE2 question

[Thomas Bohl]

Hello everyone.I'm planning to use OpenIKEv2 not just for VPN tunnel, but also 
to give client Internet access through that tunnel (none other for that 
client). Is it possible? Do I need additional config options or will default 
gateway become available on the system once connected to VPN?


Yes, and it also sets the DNS server to what the VPN server tells it to.

I discovered that

peer vpn.example.com local 2003:c8:2721:cc00:f773:7319:68a6:8ed8

works. (Even though the logs show that this address is already used you 
have to explicitly mention it via "local" again.) Since "local" accepts 
a hostname, my workaround/solution is:


peer vpn.example.com local dyndns-client.example.com

Re: Disable amdgpu driver without a working keyboard in UKC?

[Thomas Bohl]

Hello,

I wanted to try that out by running the same `disable amdgpu` command in 
UKC, but neither the built-in keyboard nor my external keyboard work in 
UKC mode.


Is there an alternative way of disabling amdgpu when my keyboards don't 
work? Perhaps I can echo to some config file during the `boot>` prompt?


You could SSH into the machine or use the the install kernel to drop 
into a shell. From there you could create a bsd.re-config file.


man bsd.re-config

iked RoadWarrior IPv6

[Thomas Bohl]

Hello,

I want to integrate a remote OpenBSD 7.2 machine into my local network. 
So it will be reachable via a local IPv4 address like 192.168.0.206. My 
local router and IPSec server is a LANCOM 1781EW+.


The setup works already, but only if iked uses IPv4 and not IPv6. (I 
have a working IPv6 setup with strongSwan on Android tough.)


# cat /etc/iked.conf
ikev2 "rathaus" active esp \
    from 192.168.0.0/24 to any \
    from dynamic to 192.168.0.0/24 \
    peer vpn.example.com \
    srcid o2@rathaus \
    psk "will-change-to-certs-if-testing-is-finished" \
    request address any \
    iface lo1

This config works if the peer entry is a IPv4 address or if 
vpn.example.com has only an A record. If vpn.example.com has an  
record or peer is a IPv6 address it will not work.

I think it might be worth repeating that packages are the recommended
way to use third-party software. And that's also a great justification
why there is no /usr/ports partition on a default install.

Unless you are doing ports development work, you shouldn't need the
ports tree. There are rare ports which don't have a package (for
license reasons). If you need one of them, CVS has the advantage over
git that you can checkout a subdirectory. If you do this for an
individual port, the space requirements should be minimal. Still, for
regular use you shouldn't need to deal with any of this.

What Nick suspects is likely true, but tcpdump will just quit on
SIGHUP. You could restart the capture instead. Capturing network traffic
for days might use a lot of disk space though.

Re: How to track system changes?

Very valuable insights. That’s a great idea. 

The rysnc script was ksh/bash or cron? Ideally I’d like to use Python to tackle

How to track system changes?

[Eric Thomas]

I want to have a high degree of confidence in my system's state
(packages that have been added, configs that have changed, permissions
changed, etc). I've read about "read only filesystems" and the
pro's/con's [here](http://geodsoft.com/howto/harden/OpenBSD/no_changes.htm).

Aside from that, is there a way to...

1. ...hash the file system in some way and monitor for changes? OR
2. ...somehow review changes that have taken place (a log somewhere)?

The goal is to concretely know whether the state of the system has
changed, then point to what EXACTLY has changed.

Anyone doing something similar?

Thank you

Internal Logging?

[Eric Thomas]

I'd like to understand more about how OpenBSD logs internal events such as:

- pkg_add/delete events
- user logins
- X session start/stops
etc.

Is there "one big log" where all of these types of events are stored?
Or are they logged in specific directories depending on log type?
Which log directories do you monitor?

Thank you!

Re: How to rebuild the ports tree?

Disregard! I see now that the `make FETCH_PACKAGES= install` installed
everything. I assumed it would get the large packages only.

Looks like running `unifi info` yields all relevant info.

Thank you very much for the patience and expertise.

@Stuart

Thank you for the (repeated!) recommendation to use `make
FETCH_PACKAGES= install`. I had originally tried the command but
missed that CRITICAL space ' ' between `=` and `install`. Now that I
have that corrected, the `make` went very quickly.

>"pkg_info | grep unifi" will show some output if it is installed

Nice! After running `make`, `pkg_info | grep unifi` shows:
"unifi-6.2.26 controller for Ubiquit..."

Last(?) issue:
Running `pkg_add unifi` (or `unifi-6.2.26`) from
`/urs/ports/net/unifi/6.2` results in:
"quirks-4.54 signed on 2022-03-26T14:02:422
Can't find unifi"

How do I get the custom build to a location where pkg_add can "see it"?

Very cool blog! I def spent some time reading. The dpb method feels

1. I was able to restore a previous checkpoint (I'm in a virtual

How to rebuild the ports tree?

[Eric Thomas]

I'm stuck. I need to install the UniFi 6.2.26 port, I used the [FAQ to
setup the ports tree](https://www.openbsd.org/faq/ports/ports.html).
This seemed to work just fine. However, the last few messages in the
`make install` output showed errors. To debug the issue, I decided to
completely uninstall the UniFi port then pipe the `make install`
output to a log.txt.

To uninstall:

- TRIED: `make uninstall`
- ERROR: `make: don't know how to make uninstall`

- TRIED:
  - `make clean`
  - `pkg_delete -a`
  - `make clean=dist`
  - `make clean=packages`
  - `make install`
- ERRORS: MANY (attached)

The question is, how to I just rebuild the ports tree and/or get it
back in a known good state?

How to determine if WiFi AP is compatible?

[Eric Thomas]

I'm trying to determine if a WiFi AP is compatible with OpenBSD. For
example, checking the [Wireless FAQ's](
https://www.openbsd.org/faq/faq6.html#Wireless), I don't see whether the
chipset used by the [UniFi Access Point WiFe 6 Pro](
https://dl.ui.com/ds/u6-pro_ds.pdf) is compatible or not.

I want to know if I need use a particular [switch](
https://store.ui.com/collections/unifi-network-switching/products/usw-lite-16-poe)
to plug the WiFi AP into, or whether I can plug the WiFi AP directly into
the OpenBSD server.

yes, I think you are right.

IF you are getting the dmesg output but not the login prompt, sounds
like you lost the change to the tty00 line in /etc/ttys, it should
look something like:

HOW that happened is worthy of investigation. sysmerge should not

no serial access anymore after upgrade

[Thomas]

Hello,

I have a bunch of firewall and router devices with serial ports only. No 
vga ports at all. After upgrading two of the devices to 7.0 I lose 
access to the console after the boot process has finished. Last thing 
that is printed on the screen is the date. Normally the log-in prompt is 
showing up after that. After boot I'm now not able to access the server 
via serial console at all anymore.


Has anyone made the same experience after upgrading?

Thanks and have a nice day,
Thomas

Does the audio work? No audio hangs/wedging anymore on more than just
a few minutes of usage? I have a machine like this, too, but audio would
hang with MSI on like previous Ryzen generations. Unlike previous Ryzen
generations, patching to switch to legacy interrupts didn't work. That
was about 1.5 years ago; it currently serves as a Windows box ...

It would be good to know if that issue went away... I wouldn't mind
putting a better OS on my machine again *cough*.

Mirrors down for maintenance?

[Thomas Vetere]

Hello everyone,

Is anyone else getting "ftp Connection refused" when trying to access the
mirrors? I checked the announcements email archive today and didn't see
anything about maintenance. I found this email chain in the archives which
is exactly what I'm experiencing.

https://www.mail-archive.com/misc@openbsd.org/msg152927.html

This chain references another set of emails that showed some mirrors were
down for maintenance at that time. I have two laptops running OpenBSD and
both seem to have this issue. I tried a bunch of other mirrors to no
success. Also I used one of them yesterday and was able to connect
successfully then so that leads me to believe the issue isn't on my end.

Thank you for your help!

Re: How to install yfklog

[Greg Thomas]

I'd read through this:

https://www.openbsd.org/faq/faq15.html

After you read that you should be able to verify if the required packages
are available on OpenBSD or not.

And then go through what you think are the correct steps.  And then ask
questions after you've written exactly what you've done if things don't
work.

Are there any OpenBSD Kernel/Architecture Books?

[Thomas Windisch]

What resources would be a good primer on the OpenBSD kernel and general
architecture and give me a good understanding of the internals?

FreeBSD has this:

https://docs-legacy.freebsd.org/doc/13.0-RELEASE/usr/local/share/doc/freebsd/en_US.ISO8859-1/books/arch-handbook/book.html

I understand that in OpenBSD there is the mantra that source code is
documentation. But as a beginner I'm afraid that I do need something 
explicit that would allow me read the source code in an effective manner.

Thanks very much to kettenis@ for fixing this!

One other observation about this implementation (this may already be
on a to-do list somewhere, in which case please count this as +1
vote): instead of a single ftlock and ftlist_shared pair, you could
hash the futex key to select among N locked lists, to avoid contention
(like FreeBSD).

Hello,

This seems to be because such memory objects have no uvm_obj, which is
needed by futex_get() to identify futexes.  Could they have one?  Or
perhaps there is some other way to make a futex key in this case?

futex(2) not working in inherited mmap'd anon memory

[Thomas Munro]

Hello,

When I do mmap(MAP_ANONYMOUS | MAP_SHARED) and then fork(), it seems
that futex(2) wakeups are not delivered between child and parent in
that memory.  It does work as expected if I instead use
shmget(IPC_PRIVATE).

Below is a standalone test program.  I tested it with the four OSes
mentioned, and the two shmem types depending on that #if, and all
worked as expected except the OpenBSD/mmap case, which hangs.

Is it a bug?

If you need audio, that might be a barrier to recent AMD CPUs:

https://marc.info/?l=openbsd-bugs=161221378203609=2
https://marc.info/?l=openbsd-bugs=160112047222899=2

Earlier Ryzen CPUs worked after disabling MSI for azalia(4), but it
seems to not be a solution anymore with later models.

For desktop, Ryzen 2xxx CPUs seem to be the last ones without the audio
limitations. I ran a Ryzen 7-2700 for a while.

If you plan to use GPU acceleration, amdgpu(4) still seems to run into
poorly predictable "freezes" where the screen stops updating. I most
recently experienced this a week or two ago on the Thinkpad X395. This
is probably still an issue with dedicated GPUs, too. Using an AMD
Radeon card type Northern Island or older would be the only solution I
can think of, but that is > 10 year old hardware and doesn't support
newer OpenGL or Vulkan.

These issues together are the reason why I personally ended up back on
Intel hardware. If your goal of "overkill with choice of hardware now"
includes using audio and GPU acceleration including newer APIs, a 10th
or 11th gen Intel CPU may be the best option.

Of course, if you don't use audio and don't need GPU acceleration, then
all these points are moot and you could just get the most powerful
Ryzen 9 you can afford. (Note you may not get a lot of return on
investment for core counts > 8.)

I copied what I needed from /var and /usr to /home and only kept /home

I did not downgrade via the "Upgrade" option but via the "Install"
option. The installer running newfs should cleared all data in /usr, /var, 
and /, right?

After rebooting I now cannot boot. The error I now get is:

I guess I'll just backup /home to another drive and do clean reinstall.

Re: Recover partition table/FFS2 after overwrite?

[Thomas Windisch]

I mangaged to restore my drive using 

#fdisk -iy
#disklabel -R
#fsck

Thanks Geoff and David.

After reinstalling OpenBSD everything seems so be running fine.
Almost.

When I now run grep I get this:

$ grep
warning: libc.so.96.0: minor version >= 1 expected, using it anyway
ld.so: grep: can't load library 'libz.so.6.0'
Killed

I was previously running -current and I reinstalled -release 6.9.
It seems that grep is a remnant of the old install? How come?

Recover partition table/FFS2 after overwrite?

[Thomas Windisch]

I think I just overwrote my file system by using sd1 instead of sd2:

# pv install69.img > /dev/rsd1c

sd1 is softraid crypto device that holds the system partitions and data:

$ df -h
Filesystem SizeUsed   Avail Capacity  Mounted on
/dev/sd1a  1.9G143M1.7G 8%/

The system is currently up and running.
I'm not sure what has been overwritten. Possibly only sd1a /?
Is it possible to recover from this without loosing access to the data in 
/home, /var, /usr?

Re: Can't figure out what's taking up space on /

[Greg Thomas]

So I found an approximate 750MB in a directory under the /backup mount
point.  Removed that and ended up with sane numbers:

Re: Can't figure out what's taking up space on /

[Greg Thomas]

Thank you Todd.  And I'm sorry to Paul for not reading his post more
thoroughly regarding the mount points.

At some point my rsync script ran while /backup wasn't mounted or
something.  The culprit was there.

Re: Can't figure out what's taking up space on /

[Greg Thomas]

I'm at a loss, I booted in single user mode, ran fsck on /dev/sd0a and it
shows clean.  I still have a large discrepancy between df and du.

Re: Can't figure out what's taking up space on /

[Greg Thomas]

Will do, but I should add that I have done nothing on this box for a couple
of months.  The day before yesterday I realized that I really needed to
backup my laptop, when I went to run my backup script I discovered that I
couldn't reach this server.  When I went to troubleshoot I couldn't login
so I hard rebooted it.

After running fsck in single user mode and letting it fix things I ended up
being able to log in which is when I discovered that / was full.

Anyway, I'll boot into single user mode later today.  I shouldn't be
troubleshooting things in the middle of the night.  I probably could have
retained some more info about my situation if I had waited til the morning
to troubleshoot the other night.

Re: Can't figure out what's taking up space on /

[Greg Thomas]

No, after the reboot I'm still in the same situation.  As mentioned earlier
I deleted /bsd.sp so I have a little more free space.

grits# df -h

I take it I'm dealing with filesystem corruption as Ali mentioned earlier?

[Greg Thomas]

I thought Paul's advice only applies if I was trying to figure it out
before rebooting?  I'd already rebooted before sending my first email.

Re: Can't figure out what's taking up space on /

[Greg Thomas]

I'm definitely suffering from filesystem corruption on root.  I had
rebooted last night with no change.

I have no options for mounting root.

grits# cat /etc/fstab
16a27b4b4549ce04.b none swap sw
16a27b4b4549ce04.a / ffs rw 1 1
16a27b4b4549ce04.k /home ffs rw,nodev,nosuid 1 2
16a27b4b4549ce04.d /tmp ffs rw,nodev,nosuid 1 2
16a27b4b4549ce04.f /usr ffs rw,nodev 1 2
16a27b4b4549ce04.g /usr/X11R6 ffs rw,nodev 1 2
16a27b4b4549ce04.h /usr/local ffs rw,wxallowed,nodev 1 2
16a27b4b4549ce04.j /usr/obj ffs rw,nodev,nosuid 1 2
16a27b4b4549ce04.i /usr/src ffs rw,nodev,nosuid 1 2
16a27b4b4549ce04.e /var ffs rw,nodev,nosuid 1 2
/dev/sd1c /backup ffs rw,nodev,nosuid 1 2

I need to upgrade so I can do that from scratch.  This is my backup server
so the configuration is pretty simple.

Not sure fsck output helps here?

grits# fsck /dev/sd0a
** /dev/rsd0a (NO WRITE)
** Last Mounted on /
** Root file system
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
12852 files, 469195 used, 35516 free (44 frags, 4434 blocks, 0.0%
fragmentation)

Anyway, I'll reinstall unless someone has more learning experiences for me.

And thank you to Paul for giving a quick explanation of the difference
between df and du.

Thanks all!

I just removed /bsd.sp to free up a little bit of space but I don't
understand the discrepancy between df and du.  How do I troubleshoot
further?

Thanks,

Enable Edge Scrolling for ALPS Touchpad

[Thomas Vetere]

Hello everyone,

I am running OpenBSD on an HP Pavilion dm1z-2000 Notebook. I am trying 
to setup edge scrolling for my Alps touchpad.


Here are the relevant dmesg entries for the device:

"*AUI1101" at acpi0 not configured
pckbc0 at isa0 port 0x60/5 irq 1 irq 12
pckbd0 at pckbc0 (kbd slot)
pms0 at pckbc0 (aux slot)
wsmouse0 at pms0 mux 0

Here is the output of xinput:

+ Virtual core pointer        id=2    [master pointer  (3)]
|   + Virtual core XTEST pointer      id=4    [slave 
pointer  (2)]
|   + /dev/wsmouse        id=7    [slave 
pointer  (2)]

+ Virtual core keyboard       id=3    [master keyboard (2)]
    + Virtual core XTEST keyboard     id=5    [slave 
keyboard (3)]
    + /dev/wskbd      id=6    [slave 
keyboard (3)]


Here is the output of wsconsctl | grep mouse:

mouse.type=ps2
mouse.reverse_scrolling=0

I've browsed the mailing archive and man pages for more info on this 
topic. This email chain in particular was informative:


https://marc.info/?t=15150076981=1=2

It got me thinking that maybe my Alps model was not included in the 
pms.c code.


I went over the code for pms.c here: 
https://github.com/openbsd/src/blob/master/sys/dev/pckbc/pms.c


I noticed that some of the version models are actually excluded in the 
code and actually default to PS2 because they use protocols that are not 
quite compatible with pms.
I know for a fact based on my machine's manual that the touchpad 
supports edge scrolling. Is there anyway I can retrieve the hex value 
for the version # of my alps touchpad without having
to debug the kernel or add some sort of printf statement and then 
recompile? I am trying to find out what my version # is to see if it 
just needs to be added to the model list as in 
https://marc.info/?t=15150076981=1=2 or if extra work is needed. 
If so, I would be interested in trying to do some driver work to enable 
the scrolling.


Thank you for your help!
