You can try figuring out what command line it uses to run pkg-config
(make -n might help) and run that yourself with --debug added to see if

slowcgi(8) chroots to /var/www by default.

The package version of cgit is statically linked to make it easier to
run in chroot (and sets the config path to /conf/cgitrc, which when run
inside this chroot ends up as /var/www/conf/cgitrc).

If running in chroot, the chroot environment will need to include
any executables/libraries/data files etc that are need to run filters.

Those ones are all normally safe to incude in /etc/mk.conf, including
for base/xenocara builds, *but* the .include will fail unless you have
the ports tree on that machine.

yabitrot and bitrot are in ports, I think they're "build a database and
check the files" and don't have anything special to identify a good copy
on a separate disk (though hopefully there will be few enough damaged
files that it's not too much hassle to do that separately).

It doesn't make sense that either changing the port or disabling/enabling
PF would make any difference as to whether SSH accepts Fido2 authentication.

Perhaps something else is happening and it's a coincidence that it happens
at the same time as you adjust configuration? Is there anything relevant
in /var/log/authlog?

That is talking about the address that mariadb server is listening on.
0.0.0.0 is "listen for requests to any v4 address on the machine".

That is talking about browsers allowing client connections *to*
0.0.0.0 which may allow javascript/html to trigger making a connection
to a service that is only listening to 127.0.0.1. Now you could still
connect to that service by connecting to 127.0.0.1, but newer browsers
specifically treat connections to localhost or private network
addresses as more highly privileged, and don't allow random websites to
do that (only trigger connections to internet servers).

That (or the v6 equivalent) doesn't work on OpenBSD anyway.

OpenBSD policy is to do native builds. It's a good way to make sure that
the OS is exercised on each arch. (And there's no infrastructure in ports
to handle cross compiles).

If you can boot with the non-mp kernel, use sendbug (run as root) to
generate a report which includes the acpi tables (often done by using
sendbug -P and copy to another machine to include in an email if you
don't have email setup on the first machine). If not, if linux runs you
can run acpidump -b from there and those files should still be useful.
Copying down the text from the crash and including that too would be
useful (if there's working serial console you can copy and paste,
otherwise it can just be copied down and retyped).

You can also try looking for firmware updates to see if the manufacturer
fixed anything on their side. IIRC HP fairly often has ACPI tables which
are a bit difficult to support though.

I'm not sure what the problem you're seeing is (suspect some kind

until you're more familiar with OpenBSD (at least if you have anything

No change of policy - those simply aren't getting built.

pandoc depends on ghc, which is amd64 only.

When attempting to build chromium and friends on i386, it usually fails
for various reasons.

In the most recent attempt, iridium and ungoogled-chromium fail with this

Last time the chromium code was actually compilable on i386, linking
failed about 80% of the time due to running into memory limits on a
32-bit platform (we do native builds on i386, not cross compiles from
amd64).

Browsers still built on i386:

(w3m, lynx, links, links+, elinks)
netsurf
dillo
seamonkey
webkitgtk-based ones (epiphany, luakit, vimb, surf, badwolf)
qtwebengine-based ones (qutebrowser, otter-browser) - though there's
a fairly good chance that future updates will break i386

Also we are also having problems with programs written in rust, the
compiler started using more memory in some more recent release, and
seeing quite a few random build failures there, so some of those will
drop in and out of package snapshots depending on whether they worked
in any particular build.

Many projects are simply not interested in resource requirements during
compilation.

Taking amd64 as 100%, here's how other archs compare in number of
packages in the latest snapshots:

arm 65
powerpc64 68
mips64 69
sparc64 70
powerpc 81
riscv64 84
i386 85
aarch64 98
amd64 100

I'm all for running hardware for a long time to get as much use out
of it as possible. But a new machine costing around GBP/EUR/USD

That is a workaround - modern resolvers ought to follow the "should"

argued as being a security bug.

That's in libc. Go does use that in some cases but not all, and it's
rather complicated to figure out which resolver will be used in any
particular case (unless forced):

https://pkg.go.dev/net#LookupHost
https://github.com/golang/go/blob/master/src/net/conf.go#L19

By setting environment variables you can force one or the other to

That depends on what user you have got lighttpd running as.
If it's the default, _lighttpd, then that yser needs to be able
to write to the log file that lighttpd is configured to use.

Seems the port docs, or perhaps defaults, could do with some
tweaks as there are definitely some things which are not obvious
(/dev/null and not mounting nodev) and are a bit hard to figure
out unless you know OpenBSD. But you might want to pick a
different web server if you're needing help with file
permissions etc as there's a lot more documentation you can
find online for e.g. nginx or apache httpd than lighttpd.

Re: lighttpd in openbsd - cant find devnull

Lighttpd is running as the _lighttpd user, not as root.

I'm running as root - so a permissions problem would seem impossible.

Unless lighttpd is changing the User from root to something else ...

NOTE: I did observe that the new User I added, dmc1, wasn't in Wheel
(just added it).

I'm not sure how lighttpd knows dmc1 is even there - I believe that
lighttpd was installed as root -

before I added the dmc1 user.

Yes. Reboot.

Try this:

$ cat /var/www/dev/null

It should just return to the prompt (same as "cat /dev/null").

If it says "Device not configured" then for some reason it still
seems to be mounted with nodev. (Or check "mount | grep /var")..

Confirmed, 16.3 does the same on -current.

There were some libc changes, it may be a bit fiddly to test with
this as there was a bump, easiest way is probably to start with
say ftp.hostserver.de:/archive/2024-08-01-0105 on a scratch machine
(it has packages too), and move forwards between snapshots, testing
initdb each time.

They probably changed the default because of the fragment problem
mentioned in "Using NFS over UDP on high-speed links" on
https://www.man7.org/linux/man-pages/man5/nfs.5.html

(This has been a problem with some commercial NAS devices too)

afaik that's an old Sun protocol and I don't think it's possible to
signal use of TCP.

Assuming /var/www/dev does not already exist, this should do it:

# mkdir /var/www/dev

If it already exists then you may need to adapt the rm command to

You'll also need to make sure that /var/www is _not_ mounted with

"/daemonized server failed to start; check error log for details doing
_rc_rm_runfile (failed)/"

error.log says:

"...

According to this:

https://www.reddit.com/r/openbsd/comments/nygjdm/lighttpd_cant_find_devnull_on_69/

there's supposed to be a directory here: /usr/sbin/chroot/ but chroot is
actually a file.

I'm not sure how to proceed to fix the dev/null problem ...

Assuming /var/www/dev does not already exist, this should do it:

# mkdir /var/www/dev
# cd /var/www/dev
# sh /dev/MAKEDEV std
# rm !(null)

If it already exists then you may need to adapt the rm command to
preserve existing entries, or use mknod(8) manually to just create
the "null" node.

You'll also need to make sure that /var/www is _not_ mounted with
the "nodev" option (/etc/fstab).

If this is a hard requirement for lighttpd then the port could
probably do with explaining it somewhere .. (maintainer cc'd)

No idea about the rs: and I couldn't find any FreeBSD docs about
what that does.

mm: looks like an address to use for memory-mapped io.

You might get somewhere with 'machine comaddr '.

Details from 'sendbug -P' run as root might give enough information
to figure out a bit more about what to do with the machine.

EAPoL frames wouldn't be forwarded by a _router_ anyway as they are not IP.

The MAC address used, 01:80:C2:00:00:03, is part of the 01:80:C2:00:00:0x
set of "MAC Bridge Filtered MAC Group Addresses" (802.1d) that a switch
is not supposed to forward.

There is a special purpose "mini switch" in OpenBSD, tpmr(4), that only
handles two ports. That one _can_ be configured to permit these protocols
(see the manual, it only talks about LACP/STP but EAPoL should be handled
the same) which might let you do what you want.

For WPA-Enterprise, wifi access points typically tunnel EAP
authentication (coming from the *client*, not the AP) to the RADIUS
server. As well as handling auth, the RADIUS server also generates
keying material for the session. OpenBSD radiusd doesn't support EAP or
this key material generation. (The EAP method used is as chosen between
client and RADIUS server).

I presume you're talking about "BlastRADIUS". This affects PAP, CHAP, or
MS-CHAP over RADIUS/UDP, not EAP, so a typical WPA-Enterprise config
is unaffected. It also requires that an attacker can view and modify
RADIUS packets in transit, clearly a big issue where somebody runs
the protocol over open internet connections (though this is something
that has never really been OK with RADIUS anyway), but much less of
a problem where it's run on a private network.

While it is a serious issue, it certainly doesn't affect all
configurations, and I can't help feeling that it's slightly overblown -
there was a lot of publicity from inkbridge (recently rebranded from
"network radius") who I note sell verification tools, upgrade guide and
Excel worksheet. Certainly useful in some situations but people should
read to see if they're actually vulnerable.

The version of FreeRADIUS with fixes requires an additional function
from libssl that libressl doesn't support yet. It's been added but
not exposed until we're ready for a library bump. Once that's done
I have an update ready to go. It won't be committed to -stable due to
the need for that libssl change and another change to libcrypto that
already went in.

See https://www.inkbridgenetworks.com/blastradius/faq and
https://www.freeradius.org/security/ for more info and mitigations that
can be done via config until the software is uodated.

I've not tried it with freerdp - in general you'll need something like

-I/usr/local/include/eopensslXX in CPPFLAGS or CFLAGS/CXXFLAGS

-Wl,-rpath /usr/local/lib/eopensslXX -L/usr/local/lib/eopensslXX in LDFLAGS

Also need to make sure that it find /usr/local/include/eopensslXX
_before_ /usr/include/openssl which often needs patches. I suggest
temporarily adding #error in some strategic file like
/usr/include/openssl/opensslconf.h to make sure that it doesn't get
included by mistake - mismatching headers and libraries is guaranteed
to cause trouble.

You'll also need to disable linking to any libraries that pull in
libressl - this includes at least cups-libs.

(btw https://junkpile.org/freerdp320.diff is the latest I have if anyone
is interested in trying to do something with timer_*.)

As far as I know that's correct, I don't think there's anywhere else
that it should be picking up the CA cert from.

BTW this is a shortcut that ikectl implements to make things easy,
although it does mean that the client's "private" key actually ends
up on the server.

The traditional way of doing this is exactly like an X509 cert for a
web server, i.e. the client generates a private key and cert signing
request, the key is never transferred off the machine, only the CSR
which is taken to the CA. The CA then uses that to produce a cert
which is signed by the CA and sent back.

See the X.509 AUTHENTICATION section in isakmpd(8) for some gory
details which are mostly hidden if you use "ikectl ca".

No, that's not how it is expected to work, you don't need the client cert
on the server, just a way to validate that it's correct (by checking the
CA's signature and, IIUC, checking the subjectAltName against srcid).

I'm able to connect to a W2022 DC using "xfreerdp /u:username
/d:somedomain /v:xx.xx.xx.xx:3389 /sec:nla" and typing the password at
the Password: prompt. I'm not sure how to tell if it's really using NLA
but I suspect that non-NLA logins are probably disabled on the Windows
side.

Have you tried the same freerdp version on e.g. Linux to see how that
works?

(Better to compare the same version if possible otherwise there is an
extra complication - the old workaround for lack of posix timers is
no longer enough, we cannot update to freerdp 3.x, so maybe missing
upstream fixes - it's possible they may have fixed something for newer
versions of Windows).

this doesn't make a lot of sense, why not either start it from the
rc script itself, or save a separate script to disk, rather than
writing to /var/run?

also if you run commands from the venv bin directory, they set
things up for you so you don't need to source "activate".

in that case, it starts as root, so it can write there (at least until

I didn't check carefully but I guess pexp doesn't match this process,
so rc_check doesn't find it running.

You could try

pexp="/var/www/htdocs/applications/netbox-4.0.7/env/bin/python

If there's an actual disk failure, you're going to have to visit.
I guess you mean "dirty filesystem that requires changes before it

No.

You can reduce the chance of fsck failing by:

- reduce writes to mounted filesystems: noatime, use memory buffers
or network for syslog, use mfs for things like /tmp /var/run
- mounting filesystems read-only where possible

Sometimes people modify /etc/rc to use "do_fsck -y" instead of just
"do_fsck" on systems like this. (imho: if the only thing you'd do when
running fsck manually is hit 'F' or keep hitting 'y' then this change
is no worse, though some people don't like it).

If a filesystem is marked "dirty" you can't mount it read-write.

> Alternatively, is there a way to have ssh access in single user mode?

Sure, start network and run sshd. You may be able to do this from
/etc/profile. You just need someone/something to press enter to the
question about running the shell...

Exactly. (Note that some consumer/small business-ish routers can handle

Some things you could perhaps try -

- does a 7.5 kernel boot? 7.4? (7.3, [..]?)
- how about trying an older bootloader (extract usr/share/mdec
files from old baseXX.tgz and installboot)
- "machine mem" output might be useful to someone looking at this

HP machines are often a bit awkward, have been for many years.

Nor on a big server either, really. Pretty much any time saved in

OpenBSD's standard library functions don't support different national
formats, so if Evolution is relying on this (e.g. strftime), it's
expected that it won't work.

Some info in setlocale(3).

Re: default route for a subset of addresses

[Stuart Henderson]

Your route-to should specify the IP to send packets to, not an interface 
(which would expand to the _local_ address on that interface)

route-to is reasonably obvious.


The problem I'm having with route-to is the packets go out the wg
interface but replies are lost.
For instance either:
pass in quick on $int_if from  to !$int_if:0 route-to wg4
or
pass in quick on $int_if from  to !$int_if:0 route-to wg4 nat-to wg4

work to get the packets to the wg interface but they don't get back to
the host on the vlan

a tcpdump on the wg interface while pinging yahoo.com from the host gives:
15:05:23.348778 192.168.77.182 > 74.6.143.25: icmp: echo request (DF)

15:05:24.395843 74.6.143.25 > 10.2.0.2: icmp: echo reply (DF)

the wg interface address is 10.2.0.2 and the wgaip is 0.0.0.0/0

I also do not see the reply hitting the $int_if which it would need to
do to get to the switch so the switch can route it to the vlan

I must be missing something.

The version of Apache httpd (1.x) that used to be in the base OS (before
it was replaced by nginx) included a patch to chroot by default. That's
never (IIRC) been the case for the 2.x versions in ports/packages.

The mod_unixd module is included in the port though - that has a way to
chroot (see https://httpd.apache.org/docs/2.4/mod/mod_unixd.html) but
isn't done by default.

Your main options are to use PF route-to (config for this is reasonably
obvious, but make sure that wgaip is set to allow the relevant addresses),
or use multiple rtables and use PF to adjust the rtable used for packets
coming from those addresses on the vlan.

route-to is reasonably obvious.

For the multiple rtables method you'd probably put the wg interface
in some other rdomain, adding an rtable with the same number as that
rdomain with a default route pointing over wg, and using PF as a
selector to select traffic from those specific addresses on the vlan and
rewrite the rtable ("pass in on XX from YY rtable 2" or similar)

No idea about that, there's no reason for this to affect anything unless
the DNS is broken or returning an incorrect address etc (or returning
a v6 address if you have broken v6 connectivity).

That can be useful, but there are some gotchas. For example you can't
use syslogc twice at the same time.

This is handled automatically for things in ports using the framework
you get with MODULES=devel/cargo.

Otherwise you will need to patch openssl-sys-*/build/main.rs to
loosen the version check.

The port can't sanely do that, because it doesn't know how the admin
has configured their system.

Also, openbsd doesn't enable filesystem quotas by default.

That is simple, use a separate filesystem for /var/postgresql.

A lot of those patches are to avoid triggering warnings from ld when
linking other programs which use the gettext library due to the
api warnings openbsd has for some libc functions.

Only thing I can really suggest at that point is uninstalling packages

transferring "list" to another machine, pkg_delete /var/db/pkg/* and
install them locally.

If the pkg database in too bad a state to pkg_delete, you could produce
a list, move /var/db/pkg out of the way, and pkg_add using that list
over the top - there will be "missing package registration, do you want
to fix?" questions which you can answer yes to.

The filesystem holding /var/db/pkg has some corruption.
I'd try running pkg_check and allow it to repair, reinstall xz
"pkg_add -r -D installed xz", and see how you get on.

The same could have happened to any package, there's nothing special

Not sure about the disk full message (spurious seems unlikely - if space

NAT certainly works on packets coming from multiple hops away.

Check your pf rules carefully. And check your routing/bridging config
carefully, this setup with loads of veb and whatever vports certainly
makes things more complicated. Do you actually need it, what are you
trying to achieve with it? Simplify if you can. As far as I'm concerned
ridging on pf boxes would be a special case that I'd try to avoid unless
there's no alternative.

Standard PF diagnosis tools are to add "log" to various rules, or add
"match log(matches)" to the top of the ruleset, and tcpdump -nei pflog0,
but N.B. due to a bug in (iirc) 7.3 to 7.5 the rule numbers printed by
tcpdump will be wrong if you have any anchors in the ruleset - that's
fixed in -current.

> match out on egress from !(egress:network) to any nat-to (egress:0)

This line by itself doesn't help much, the position of the match rule
(and of course any "set skip") can make a difference.

For simplicity and performance I'd also suggest:

- avoid "from !(egress:network)", there aren't many places where this
is really useful. listing the specific prefix or prefixes that you want
to nat (10.0.0.0/8 might work for you) is simpler to debug and avoids an
extra couple of lookups for each newly created state.

- avoid "nat-to (egress:0)" if possible (only needed for a dynamic
address) and use a specific address instead.

Best you can do is checkout from a couple of mirrors (verifying ssh key
fingerprints against the set on https://www.openbsd.org/anoncvs.html
to guard against mitm) and compare the checkouts (being aware that they
may have been updated at different times so might not all have the most
recent commits).

Probably an Android sftp client, or termux + rsync. You'll be lucky if
you can get USB between OpenBSD and Android working well enough for the

A lot of this is down to Linux having spent more time on optimising
things for power consumption. Things like choices made in the scheduler
(deciding which cpu to run a process on) have an effect, especially on
certain cpu types, as well as code selecting cpu frequencies etc.

The kernel can read NMEA sentences - see nmea(4), ldattach(8).
It populates sensors; openntpd can read the time from there.

It's not an efficient operation in the first place; kernel lookup is
done with the address/prefix as a key and the flags (B/R etc) are only
found once you've fetched a route (similar if you wanted to e.g. find
routes with a specific destination router).

In order to find all routes with a certain flag you do need to dump
the whole route table and check it.

It could be done slightly more efficiently with a check for the
relevant flag rather than going via a text processing tool like grep,
but I bet the actual overall time isn't going to be very different...

The softraid device is attached but IIUC the filesystem on that device

USB drive != "USB stick" (not that 200GB is much for a USB stick these
days).

(use bs=1m on the writing side to write in larger chunks if you're
dd'ing to flash media or SMR HDD).

If you don't trust the machine you're attaching it to, you're screwed
anyway.

And some of the tools that might be able to help with recovery won't be
much help with a softraid-encrypted disk.

Turning it directly into a working filesystem is probably not going to
happen.

You need to try to extract what bits of data are still recoverable.
Think more in terms of trying to find what valid files you can and
copying them elsewhere.

Yeah, you want to treat that copy as read-only, the same way you'd treat
any drive you're trying to recover data from as read-only.

If you're going to try and write anything to it, you'll then want
_another_ copy to work on.

At one point I had access to R-Studio for something else (Windows RAID
recovery) and tried pointing it at slightly broken OpenBSD FFS while
I was there to see how it went - much better than I thought it would -
though it was pre FFS2 and I don't have access any more to check if
it's still useful. Might possibly be worth a try (obviously with
a copy not a live drive).

If this is really important, I suggest going to buy another drive to
plug in and dd to rather than trying to do anything complicated.

make sure that your ports tree is up to date for whichever version of
OpenBSD that you're using (cvs head for -current, OPENBSD_7_5 for

you must, but then do the relevant cvs update), then:

Why do you want to run three drives in softraid RAID5?

You'll get the same capacity with three drives in RAID1, and it will
be simpler and much easier to recover in a failure situation.

Oh, huh, it didn't help after just restarting firefox, but did after

It's isolated to firefox, afaik most likely (maybe only likely?)
to occur if you don't use a "desktop environment", it's due to
https://bugzilla.mozilla.org/show_bug.cgi?id=1871863
(see also https://bugzilla.mozilla.org/show_bug.cgi?id=1876366#c15)

That is the hack they added that is supposed to undo this change.
It doesn't do anything for me though.

If you're not using a desktop environment, you can run xsettingsd
with this in .xsettingsd to set a cursor theme:

Gtk/CursorThemeName "Adwaita"

However then in some setups you'll get stupidly large pointers in
Gtk based software.

If the installer booted from it, that means BIOS/UEFI was able to

rdomains will at least complicate things as you then need a way to
"leak" routes between rdomains, plus I don't think you need them.

I don't think the vether is doing anything useful either, and I think
the separate MAC is working against you

I think this should be possible with the standard route table, without
route-to. Essentially you need:

1. your machine to answer arp for the wg ip so other hosts will send
ethernet packets to it

2. your machine to not be configured with the wg ip itself

3. route entries such that those packets end up sent out the wg interface
(you may possibly need a route command with -ifp wg0)

Exactly. dmesg | grep smt will make it obvious. The cache information

Definitely is. I run externally accessible machines on my home network this way

have
left it that way since).

Configure the IP address on the wg interface with some subnet of 1.2.4.0/24 that
includes 1.2.4.5, and use wgaip 1.2.4.5/32 (or a larger block if you wish to

Set net.inet.ip.forwarding as usual.

Without a license the default position in many jurisdictions is "this is

Putting the license and warranty disclaimer on every file is to make

No.

Bridging a vlan with the physical interface used as parent for that vlan
makes no sense at all.

In some cases you might want to bridge a vlan with a *different* physical
interface.

Seems like whatever you're connecting to is either not sending you vlan

There is nothing in either the ISC license used in OpenBSD (or in the
GNU public license for that matter), to prevent people from doing that.
People who receive the code under that license are of course allowed
to pass it on though.

The ethos of the license typically used for OpenBSD code is basically
"do what you want with this code" (but expressed in a way that tries to
cover all the bases). If you want to restrict commercial use then it's
the wrong license to use.

If they've removed or changed the license, that isn't allowed (though they
can add an additional license for changes). Actual enforcement might well
be difficult/expensive though.

Unlikely. If the provider have their own assignment from an RIR it's
probably at least a /32. /48 is common for a single user running
multiple networks, many providers (even just end-user DSL/FTTP ISPs)
give their users a /48 that they can subnet as they wish.

It's an extremely annoying misfeature in ksh.

If $EDITOR starts with the letters "vi" then it defaults to vi-style
command line editing. You can use "set -o emacs" to override that, but
then if you sudo/doas to root it will reset to vi-style editing because
of the exported EDITOR variable.

On some machines I got fed up enough with this to symlink
"emacs-notreally" to vim and set EDITOR=emacs-notreally...

IKEv2 with certs signed by a publically trusted CA is fairly easy
to work with on the client side. The server side is a bit fiddly on
OpenBSD; iked can send the necessary intermediate certs now but it's not
obvious which file they need to go in (and I forgot the details..)

IKEv2 certainly can, it depends on the software. The in-tree
version of iked doesn't have a way to do it yet, but the patches at
https://marc.info/?l=openbsd-tech&m=170895540813042&w=2 allow doing that
via RADIUS config.

Yes, modify /etc/rc (or the kernel) and you can make it happen earlier.

wireguard doesn't have a "reconnection" in the way IKEv2+MSCHAP or
IKE+L2TP do, the user doesn't have to do anything, so as long as peers
are configured on all carp members it should be fairly seamless.

It doesn't care about IP addresses as long as one end can get packets
through to the other's last known address.

(Reason for ifstated would be to stop any carp backup machines from
trying to send wireguard packets and confusing things.)

ktrace might give clues as to exactly what it's asking the kernel
to do, which might allow working out where the EACCES comes from.

It maybe worth seeing whether wg combined with ifstated might
do the trick (bring wg down when carp is down, and vice-versa).

That's just nm(1)'s display format using %08lx. Install one of the package
versions of llvm and use llvm-nm-$version and you'll see it printed with
a wider column.

Probably not bizarre. I expect they arrange things so that everything
under /var/www/pixelfed/public can be read-only (or at least not writable
by the user running the web server).

httpd is in a chroot jail so the absolute symlink won't work.

Either use a relative symlink for the above link, or set things up so
that /var/www still works inside the chroot -

mkdir /var/www/var; ln -s .. /var/www/var/www

Can't say for sure what somebody might like to work on, but from reading
posts from people using these on other OS (which aren't very positive)
I wouldn't think this is worth the trouble. I'd suggest looking for an
iwm or iwx card in the same form factor (which shouldn't be expensive)
and try swapping it.
