<h3>What's New</h3>
<p>
This is a partial list of new features and systems included in OpenBSD 6.7.
For a comprehensive list, see the <a href="plus67.html">changelog</a> leading
to 6.7.
<ul>
<li>General improvements and bugfixes:
<ul>
<li>Reduced the minimum allowed number of chunks in a CONCAT
volume from 2 to 1, increasing the number of volumes which can be
created on a single disk with <a
href="https://man.openbsd.org/bioctl">bioctl(8)</a> from 7 to 15. This
can be used to create more partitions than previously.
<li>Rewrote the <a href="https://man.openbsd.org/cron">cron(8)</a>
flag-parsing code to be getopt-like, allowing tight formations like
-ns and flag repetition. Renamed the "options" field in <a
href="https://man.openbsd.org/crontab.5">crontab(5)</a> to "flags".
<li>Added <a
href="https://man.openbsd.org/man5/crontab.5">crontab(5)</a> -s flag
to the command field, indicating that only a single instance of the
job should run concurrently.
<li>Added <a href="https://man.openbsd.org/cron">cron(8)</a>
support for random time values using the ~ operator.
<li>Allowed <a href="https://man.openbsd.org/cwm">cwm(1)</a>
configuration of window size based on percentage of the master window
during horizontal and vertical tiling actions.
<li>Allowed use of window-htile and window-vtile with the "empty"
group clients in <a href="https://man.openbsd.org/cwm">cwm(1)</a>.
<li>Switched powerpc to a machine-independent mplock implementation,
allowing use of <a href="https://man.openbsd.org/witness">
witness(4)</a>.
<li>Added <a href="https://man.openbsd.org/acpi">acpi(4)</a>
support for the _CCA method, indicating whether DMA is cache-coherent.
<li>Switched the default compiler on powerpc to clang.
<li>Bumped <a href="https://man.openbsd.org/nvme">nvme(4)</a> max
physio() i/o size to 128K.
<li>Improved <a href="https://man.openbsd.org/apmd">apmd(8)</a>
support for automatic suspend/hibernate (-z/-Z). The daemon now
reacts to power changes messages sent by the battery driver.
Those messages are ignored for 60 seconds after a resume, so
that the user can take control before the machine goes back to
sleep.
<li>Prevented a kernel hang when no unlocked ffs_softdep worklist
items could be processed.
<li>Stopped counting pages mapped as PROT_NONE against the
RLIMIT_DATA limit, helping code which reserves large chunks of address
space but populates it sparsely.
<li>Added the $REQUEST_SCHEME variable to <a
href="https://man.openbsd.org/httpd.conf">httpd.conf(5)</a>, allowing
preservation of the original connection type (http or https) for
redirect locations
<li>Implemented "strip" option in <a
href="https://man.openbsd.org/httpd.conf">httpd.conf(5)</a> for
fastcgi to be able to have multiple chroots under /var/www for FastCGI
servers.
<li>Changed <a href="https://man.openbsd.org/httpd">httpd(8)</a>
to send a 408 response when a timeout happens while headers are being
received, but close the connection if no request is received.
<li>Updated en_US.UTF-8.src to Unicode 12.1.
<li>Added a new __tmpfd system call which creates a new, unnamed file in
/tmp, intended for shm/fd passing, but in programs that may otherwise
lack filesystem access (due to restrictions imposed by
<a href="https://man.openbsd.org/unveil.2">unveil(2)</a> or
<a href="https://man.openbsd.org/pledge.2">pledge(2)</a>).
<li>Imported <a href="https://man.openbsd.org/dt">dt(4)</a>, a
driver and framework for Dynamic Profiling, and an accompanying bug
tracer that speaks the <a href="https://man.openbsd.org/dt">dt(5)</a>
language.
<li>Added a human-readable mode (-h) to <a
href="https://man.openbsd.org/systat">systat(1)</a>.
<li>Implemented scrolling in <a
href="https://man.openbsd.org/top">top(1)</a> using the 9 and 0 keys.
<li>Added <a
href="https://man.openbsd.org/timeout_set_flags">timeout_set_flags(9)</a>
and TIMEOUT_INITIALIZER_FLAGS(9) to the timeout API, allowing the
caller to initialize timeouts with arbitrary flags.
<li>Introduced TIMEOUT_SCHEDULED flag and tos_scheduled statistic
to <a href="https://man.openbsd.org/timeout.9">timeout(9)</a>.
<li>Switched to tickless backend in <a
href="https://man.openbsd.org/timeout.9">timeout(9)</a>, adding new
interface <a
href="https://man.openbsd.org/timeout_add_ts">timeout_add_ts(9)</a> to
avoid backwardly compatible behavior.
<li>Added the system clock interface <a
href="https://man.openbsd.org/nanoboottime">nanoboottime(9)</a>,
returning the UTC time at which the system booted in seconds and
nanoseconds.
<li>Introduced efficient page freeing in reverse order from uvm,
greatly improving cases of massive page freeing.
<li>Added uvm_objfree to uvm to efficiently free all pages from a
uvm object, used in the buffer cache for considerable speedup when
freeing pages.
<li>Modified buffer cache to use individual uvm_objs per buffer to
speed page lookups.
<li>Speed up <a href="https://man.openbsd.org/sort">sort(1)</a> by
not performing a top-level sort when -c is used with a -k field.
<li>Modified -z mode verification in <a
href="https://man.openbsd.org/signify">signify(1)</a> to save the
header and output it, so signify -zV >saved.tgz will keep the
signature for later checks.
<li>Enabled DNSSEC validation in <a
href="https://man.openbsd.org/unbound">unbound(8)</a> by default.

to configure <a href="https://man.openbsd.org/carp.4">carp(4)</a>
interfaces.
<li>Fixed <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>
releasing leases without a server identifier.
<li>Improved <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>
NAK handling in various corner cases.
<li>Fixed <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>
endlessly sending REQUEST messages when an ACK is never received.
<li>Prevented
<a href="https://man.openbsd.org/dhcpd.8">dhcpd(8)</a>
from referencing freed memory when releasing a lease with
an unusually long uid.
<li>Corrected parsing of classless static default route "0/0" in
<a href="https://man.openbsd.org/dhcpd.conf.5">dhcpd.conf(5)</a>.

<li>Stop connecting to any available unencrypted wifi networks when an
interface is marked up. This behavior must now be explicitly enabled
with <code><a href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> join
""</code>.
<li>A background scan is now triggered when root runs the <a
href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> scan command.
This updates the list of cached APs displayed by the scan command and
forces a search for a better AP to roam to.
<li>Add <code>nwflag nomimo</code> which can be set with <a
href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> to work
around packet loss in 11n mode if the wireless network device has
unused antenna connectors.

of the Rx block ack sequence number window and queue.
<li>Fixed a bug where outstanding frames on the <a
href="https://man.openbsd.org/iwn">iwn(4)</a> aggregation queue
interfered with roaming to another AP.
<li>Fixed a race condition in <a
href="https://man.openbsd.org/iwm">iwm(4)</a> Rx interrupt handling.
<li>Implemented a workaround for missing Tx completion interrupts
in <a href="https://man.openbsd.org/iwm">iwm(4)</a> which could lead
to failures when roaming to another AP.
<li>Re-enabled firmware-based Tx retries at lower rates for <a
href="https://man.openbsd.org/iwm">iwm(4)</a>, reducing packet loss.
<li>Fixed automatic Tx rate control issues in <a
href="https://man.openbsd.org/iwm">iwn(4)</a>, and <a
href="https://man.openbsd.org/iwm">iwm(4)</a>.

<ul>
<li><a href="https://man.openbsd.org/unveil.2">unveil(2)</a> is
now used in 82 userland programs to redact filesystem access.
<li>Used <a href="https://man.openbsd.org/unveil">unveil(2)</a> to
reduce filesystem access in <a
href="https://man.openbsd.org/vmstat">vmstat(8)</a>, <a
href="https://man.openbsd.org/iostat">iostat(8)</a> and <a
href="https://man.openbsd.org/systat">systat(1)</a>.
<!-- dig -->
<li>Extracted <a href="https://man.openbsd.org/dig">dig(1)</a>, <a
href="https://man.openbsd.org/host">host(1)</a> and <a
href="https://man.openbsd.org/nslookup">nslookup(1)</a> from the
bind(8) source code and cleaned up the source code by removing not
needed features and auditing it. The kernel API accessible to these
programs is now restricted through <a
href="https://man.openbsd.org/pledge">pledge(2)</a>.
<li>System calls may now only be performed from selected code regions:
the main program, <a href="https://man.openbsd.org/ld.so">ld.so(1)</a>,
libc.so and the signal trampoline. A new system call
<a href="https://man.openbsd.org/msyscall">msyscall(2)</a> indicates
the libc range, and activates the locking. This change hardens
against some attack methods.
<li>Prevented stack trace saving from inspecting untrusted data on

TMOUT is an integer literal to prevent command execution from the
environment at shell initialization time.
<li>Ensured the first 2MB page of the amd64 kernel is correctly
mapped read-only in the direct map.
<li>Addressed an armv7/arm64 speculative execution issue by changing the
system call ABI to skip two instructions and inserting a barrier
after each system call.
<li>Fixed arm64 speculative execution of instructions after ERET,
which had led to spectre-like effects on some processors.
<li>Tightened permissions for USB device nodes.
<li>Ensured that <a
href="https://man.openbsd.org/ld.so">ld.so(1)</a> removed the
LD_LIBRARY_PATH environment variable for set-user-ID and set-group-ID
executables in low memory conditions.
<li>Added support for RSA-PSS to <a
href="https://man.openbsd.org/crypto">crypto(3)</a>.

<li>Fixed insufficient username validation performed by libc's
authentication privilege separation layer and added additional
validation points, further validating in <a
href="https://man.openbsd.org/login">login(1)</a> and <a
href="https://man.openbsd.org/su">su(1)</a>.
<li>Prevented escalation to the auth group in <a
href="https://man.openbsd.org/xlock">xlock(1)</a> through path-related
environment variables and disabled mesa and opengl functionality.

blocks. Introduced <code>no local-address</code> to reset a previously
set local address.
<li>Properly aggregate duplicate <a href="https://man.openbsd.org/bgpd">
bgpd(8)</a> roa table prefix/source-as combinations into a single entry
with the longest maxlen length.
<li>Implemented <a
href="https://man.openbsd.org/bgpd.conf">bgpd.conf(5)</a>
<code>max-prefix NUM out</code> to limit the number of announced
prefixes, avoiding leaks of full tables to upstreams and peers.

ignoring it and using only the prefixlen argument.
<li>Fixed <a href="https://man.openbsd.org/snmp">snmp(1)</a> agent
address parsing to allow IPv6 addresses to be used based on format,
allow those without brackets to skip the port if it results in a
nonsensical address (allowing use of ::1), and try to connect to the
address immediately.
<li>Implemented a df subcommand for <a
href="https://man.openbsd.org/snmp">snmp(1)</a> which outputs disk and
memory information in a <a href="https://man.openbsd.org/df">df(1)</a>
format.
<li>Implemented a -Cs option in <a

arbitrary commands from being run with the _smtpq group.
<li>Allowed <a
href="https://man.openbsd.org/mail.local">mail.local(8)</a> to be run
as non-root, opening a pipe to <a
href="https://man.openbsd.org/lockspool">lockspool(1)</a> for file
locking.

changed. Most options have been folded under the -O flag.
<li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
the sshd listener process title visible to ps(1) has
changed to include information about the number of connections that
are currently attempting authentication and the limits configured
by MaxStartups.
<li><a href="https://man.openbsd.org/ssh-sk-helper.8">ssh-sk-helper(8)</a>:
this is a new binary. It is used by the FIDO/U2F
support to provide address-space isolation for token middleware
libraries (including the internal one). It needs to be installed
in the expected path under /usr/libexec.
</ul>
<li>New Features
<ul>
<li>Allowed use of the IgnoreRhosts directive anywhere in an <a
href="https://man.openbsd.org/sshd_config">sshd_config(5)</a> file,
not just before Match blocks, and made it a tri-state option.
<li>Added TOKEN percent expansion (i.e. userid, hostnames etc.) to <a
href="https://man.openbsd.org/ssh">ssh(1)</a> LocalForward and
RemoteForward when used for Unix domain socket forwarding.

href="https://man.openbsd.org/sshd_config">sshd_config(5)</a>
algorithm keywords as an alias for the corresponding query.
<li>Updated to libfido2 780ad3c25.
<li>Added an <a
href="https://man.openbsd.org/sshd_config">sshd_config(5)</a>
"Include" directive to allow inclusion of files.
<li>Renamed <a href="https://man.openbsd.org/ssh-add">ssh-add(1)</a>
-O to -K to load resident keys from a FIDO authenticator.
<li>Added the ability to download FIDO2 resident keys from a token
via the <a href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>
-K option and save public/private keys into the current directory.
<li>Implemented support for generating FIDO2 resident keys. "ssh-add
-O" will load resident keys from a FIDO2 token and add them to an
ssh-agent. Removed the -x option currently used for the
FIDO/U2F-specific key flags, now under -O.
<li>Removed single letter flags for moduli generation in <a
href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a> and moved
all moduli generation options to under the -O flag. Breaks existing

path in <a href="https://man.openbsd.org/ssh">ssh(1)</a>.
<li>Allowed <a href="https://man.openbsd.org/ssh">ssh(1)</a> security
keys to act as host keys as well as user keys.
<li>Used ssh-sk-helper for all security key signing operations and
security key enrollment. Most <a
href="https://man.openbsd.org/ssh">ssh(1)</a> tools no longer need to
link against libfido2 or interact with /dev/uhid* directly.
<li>Added "no-touch-required" options to <a
href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a> and <a
href="https://man.openbsd.org/sshd">sshd(8)</a> to disable touch
requirement for authorized_keys and certificates.
<li>Added an <a
href="https://man.openbsd.org/sshd_config">sshd_config(5)</a>
PubkeyAuthOptions directive allowing specification of whether <a
href="https://man.openbsd.org/sshd">sshd(8)</a> should check whether
user presence was tested before a security key was made.
<li>Added direct support for U2F/FIDO2 security keys in <a
href="https://man.openbsd.org/ssh">ssh(1)</a>.
<li>Added initial infrastructure for U2F/FIDO support in <a
href="https://man.openbsd.org/ssh">ssh(1)</a>.
<li>Notified the user via TTY or $SSH_ASKPASS when <a
href="https://man.openbsd.org/ssh">ssh(1)</a> security keys must be
tapped/touched in order to perform a signature operation.
<li>Enabled ed25519 support in <a
href="https://man.openbsd.org/ssh">ssh(1)</a>.
</ul>
<li>Bugfixes
<ul>
<li>Detected and prevented simple <a
href="https://man.openbsd.org/ssh">ssh(1)</a> configuration loops when
using ProxyJump.
<li>Fixed PIN entry bugs on FIDO in <a
href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>.
<li>Fixed <a
href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a> not
displaying the authenticator touch prompt.
<li>Prevented a timeout in <a
href="https://man.openbsd.org/ssh">ssh(1)</a> when the server doesn't
immediately send a banner, such as with multiplexers like sslh.
<li>Adjusted on-wire signature encoding for ecdsh-sk <a
href="https://man.openbsd.org/ssh">ssh(1)</a> keys to better match
ec25519-sk keys.
<li>Fixed a potential NULL dereference for revoked hostkeys in <a
href="https://man.openbsd.org/ssh">ssh(1)</a>.
<li>ssh(1): fix IdentitiesOnly=yes to also apply to keys loaded from
a PKCS11Provider
<li>ssh-keygen(1): avoid NULL dereference when trying to convert an
invalid RFC4716 private key.
<li>scp(2): when performing remote-to-remote copies using "scp -3",
start the second ssh(1) channel with BatchMode=yes enabled to
avoid confusing and non-deterministic ordering of prompts.
<li>ssh(1): fix incorrect error message for "too many known hosts
files."
<li>ssh(1): make failures when establishing "Tunnel" forwarding
terminate the connection when ExitOnForwardFailure is enabled
<li>ssh-keygen(1): fix printing of fingerprints on private keys and add
a regression test for same.
<li>sshd(8): document order of checking AuthorizedKeysFile (first) and
AuthorizedKeysCommand (subsequently, if the file doesn't match)
<li>sshd(8): document that /etc/hosts.equiv and /etc/shosts.equiv are
not considered for HostbasedAuthentication when the target user is
root
<li>ssh(1), ssh-keygen(1): fix NULL dereference in private certificate
key parsing (oss-fuzz #20074).
<li>ssh(1), sshd(8): more consistency between sets of %TOKENS are
accepted in various configuration options.
<li>ssh(1), ssh-keygen(1): improve error messages for some common
PKCS#11 C_Login failure cases
<li>ssh(1), sshd(8): make error messages for problems during SSH banner
exchange consistent with other SSH transport-layer error messages
and ensure they include the relevant IP addresses
<li>various: fix a number of spelling errors in comments and debug/error
messages
<li>ssh-keygen(1), ssh-add(1): when downloading FIDO2 resident keys
from a token, don't prompt for a PIN until the token has told us
that it needs one. Avoids double-prompting on devices that
implement on-device authentication.
<li>sshd(8), ssh-keygen(1): no-touch-required FIDO certificate option
should be an extension, not a critical option.
<li>ssh(1), ssh-keygen(1), ssh-add(1): offer a better error message
when trying to use a FIDO key function and SecurityKeyProvider is
empty.
<li>ssh-add(1), ssh-agent(8): ensure that a key lifetime fits within
the values allowed by the wire format (u32). Prevents integer
wraparound of the timeout values
</ul>
</ul>
<li>Mandoc 1.14.6
<ul>
<li>Introduced a new <a
href="https://man.openbsd.org/mdoc">mdoc(7)</a> macro .Tg ("tag") to
explicitly mark a place as defining a term, and improved automatic
tagging in various ways.
<li>Print the manpath when the <a
href="https://man.openbsd.org/man.1#w">man(1) -w</a> option
is given without an argument, for compatibility with the man-1.6
and man-db implementations.
<li>Deleted support for the <a
href="https://man.openbsd.org/OpenBSD-6.6/man.conf.5#_whatdb"
>_whatdb</a> configuration directive from
<a href="https://man.openbsd.org/man.conf.5">man.conf(5)</a>
five years after it was declared obsolete; use <a
href="https://man.openbsd.org/man.conf.5#manpath">manpath</a> instead.
<li>Added a Content-Security-Policy HTTP header to <a
href="https://man.openbsd.org/man.cgi.8">man.cgi(8)</a>
that allows only CSS.
<li>Provide a STYLE message when <a
href="https://man.openbsd.org/mandoc.1">mandoc(1)</a> knows the
filename and the extension disagrees with the section number
given in the .Dt or .TH macro.
<li>When the <a href="https://man.openbsd.org/mdoc.7">mdoc(7)</a> .Dd
macro lacks an argument, use the empty string, and always
concatenate all arguments, no matter their number.
The same change was applied to groff.
</ul>

<p>
Quick installer information for people familiar with OpenBSD, and the use of
the "<a href="https://man.openbsd.org/disklabel.8">disklabel</a> -E" command.
If you are at all confused when installing OpenBSD, read the relevant
INSTALL.* file as listed above!
<h3>OpenBSD/alpha:</h3>
<p>
If your machine can boot from CD, you can write <i>install67.iso</i> or
<i>cd67.iso</i> to a CD and boot from it.
Refer to INSTALL.alpha for more details.
<h3>OpenBSD/amd64:</h3>
<p>
If your machine can boot from CD, you can write <i>install67.iso</i> or
<i>cd67.iso</i> to a CD and boot from it.
You may need to adjust your BIOS options first.
<p>
If your machine can boot from USB, you can write <i>install67.fs</i> or
<i>miniroot67.fs</i> to a USB stick and boot from it.
<p>
If you can't boot from a CD, floppy disk, or USB,
you can install across the network using PXE as described in the included
INSTALL.amd64 document.
<p>
If you are planning to dual boot OpenBSD with another OS, you will need to
read INSTALL.amd64.
<h3>OpenBSD/arm64:</h3>
<p>
Write <i>miniroot67.fs</i> to a disk and boot from it after connecting
to the serial console. Refer to INSTALL.arm64 for more details.
<h3>OpenBSD/armv7:</h3>
<p>
Write a system specific miniroot to an SD card and boot from it after connecting
to the serial console. Refer to INSTALL.armv7 for more details.
<h3>OpenBSD/hppa:</h3>
<p>
Boot over the network by following the instructions in INSTALL.hppa or the
<a href="hppa.html#install">hppa platform page</a>.
<h3>OpenBSD/i386:</h3>
<p>
If your machine can boot from CD, you can write <i>install67.iso</i> or
<i>cd67.iso</i> to a CD and boot from it.
You may need to adjust your BIOS options first.
<p>
If your machine can boot from USB, you can write <i>install67.fs</i> or
<i>miniroot67.fs</i> to a USB stick and boot from it.
<p>
If you can't boot from a CD, floppy disk, or USB,
you can install across the network using PXE as described in
the included INSTALL.i386 document.
<p>
If you are planning on dual booting OpenBSD with another OS, you will need to
read INSTALL.i386.
<h3>OpenBSD/landisk:</h3>
<p>
Write <i>miniroot67.fs</i> to the start of the CF
or disk, and boot normally.
<h3>OpenBSD/loongson:</h3>
<p>
Write <i>miniroot67.fs</i> to a USB stick and boot bsd.rd from it
or boot bsd.rd via tftp.
Refer to the instructions in INSTALL.loongson for more details.
<h3>OpenBSD/luna88k:</h3>
<p>
Copy 'boot' and 'bsd.rd' to a Mach or UniOS partition, and boot the bootloader
from the PROM, and then bsd.rd from the bootloader.
Refer to the instructions in INSTALL.luna88k for more details.
<h3>OpenBSD/macppc:</h3>
<p>
Burn the image from a mirror site to a CDROM, and power on your machine
while holding down the <i>C</i> key until the display turns on and
shows <i>OpenBSD/macppc boot</i>.
<p>
Alternatively, at the Open Firmware prompt, enter <i>boot cd:,ofwboot
/6.7/macppc/bsd.rd</i>
<h3>OpenBSD/octeon:</h3>
<p>
After connecting a serial port, boot bsd.rd over the network via DHCP/tftp.
Refer to the instructions in INSTALL.octeon for more details.
<h3>OpenBSD/sgi:</h3>
<p>
To install, burn cd67.iso on a CD-R, put it in the CD drive of your
machine and select <i>Install System Software</i> from the System Maintenance
menu. Indigo/Indy/Indigo2 (R4000) systems will not boot automatically from
CD-ROM, and need a proper invocation from the PROM prompt.
Refer to the instructions in INSTALL.sgi for more details.
<p>
If your machine doesn't have a CD drive, you can setup a DHCP/tftp network
server, and boot using "bootp()/bsd.rd.IP##" using the kernel matching your
system type. Refer to the instructions in INSTALL.sgi for more details.
<h3>OpenBSD/sparc64:</h3>
<p>
Burn the image from a mirror site to a CDROM, boot from it, and type
<i>boot cdrom</i>.
<p>
If this doesn't work, or if you don't have a CDROM drive, you can write
<i>floppy67.fs</i> or <i>floppyB67.fs</i>
(depending on your machine) to a floppy and boot it with <i>boot
floppy</i>. Refer to INSTALL.sparc64 for details.
<p>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
<p>
You can also write <i>miniroot67.fs</i> to the swap partition on
the disk and boot with <i>boot disk:b</i>.
<p>
If nothing works, you can boot over the network as described in INSTALL.sparc64.

<h3>How to upgrade</h3>
<p>
If you already have an OpenBSD 6.6 system, and do not want to reinstall,
upgrade instructions and advice can be found in the
<a href="faq/upgrade67.html">Upgrade Guide</a>.
</section>
<hr>
<section id=sourcecode>
<h3>Notes about the source code</h3>
<p>
<code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
This file contains everything you need except for the kernel sources,
which are in a separate archive.
To extract:
<blockquote><pre>
# <kbd>mkdir -p /usr/src</kbd>
# <kbd>cd /usr/src</kbd>
# <kbd>tar xvfz /tmp/src.tar.gz</kbd>
</pre></blockquote>
<p>
<code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
This file contains all the kernel sources you need to rebuild kernels.
To extract:
<blockquote><pre>
# <kbd>mkdir -p /usr/src/sys</kbd>
# <kbd>cd /usr/src</kbd>
# <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
</pre></blockquote>
<p>
Both of these trees are a regular CVS checkout. Using these trees it
is possible to get a head-start on using the anoncvs servers as
described <a href="anoncvs.html">here</a>.
Using these files
results in a much faster initial CVS update than you could expect from
a fresh checkout of the full OpenBSD source tree.
</section>
<hr>
<section id=ports>
<h3>Ports Tree</h3>
<p>
A ports tree archive is also provided. To extract:
<blockquote><pre>
# <kbd>cd /usr</kbd>
# <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
</pre></blockquote>
<p>
Go read the <a href="faq/ports/index.html">ports</a> page
if you know nothing about ports
at this point. This text is not a manual of how to use ports.
Rather, it is a set of notes meant to kickstart the user on the
OpenBSD ports system.
<p>
The <i>ports/</i> directory represents a CVS checkout of our ports.
As with our complete source tree, our ports tree is available via
<a href="anoncvs.html">AnonCVS</a>.
So, in order to keep up to date with the -stable branch, you must make
the <i>ports/</i> tree available on a read-write medium and update the tree
with a command like:
<blockquote><pre>
# <kbd>cd /usr/ports</kbd>
# <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_7</kbd>
</pre></blockquote>
<p>
[Of course, you must replace the server name here with a nearby anoncvs
server.]
<p>
Note that most ports are available as packages on our mirrors. Updated
ports for the 6.7 release will be made available if problems arise.
<p>
If you're interested in seeing a port added, would like to help out, or just
would like to know more, the mailing list
<a href="mail.html">ports@openbsd.org</a> is a good place to know.
