1.3 guenther 202: <li><tt>W^X</tt> is now strictly enforced by default;

1.6 schwarze 205: mounted with the <tt>wxallowed</tt>
206: <a href="http://man.openbsd.org/mount.8">mount(8)</a> option.
1.36 deraadt 207: Because there are still too many ports which violate W^X, the
208: installer mounts the <tt>/usr/local</tt> filesystem with
209: <tt>wxallowed</tt>. This allows the base system to be more
1.37 tb 210: secure as long as <tt>/usr/local</tt> is a separate filesystem.
1.36 deraadt 211: If you use no W^X violating programs, consider manually

241: and UDP ports with
242: <a href="http://man.openbsd.org/sysctl.8">sysctl(8)</a>
243: <tt>net.inet.tcp.rootonly</tt> and

872: which are in a separate archive.
873: To extract:
1.1 deraadt 874:
875: <blockquote><pre>
876: # <b>mkdir -p /usr/src</b>
877: # <b>cd /usr/src</b>
878: # <b>tar xvfz /tmp/src.tar.gz</b>

880:
1.6 schwarze 881: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
1.1 deraadt 882: This file contains all the kernel sources you need to rebuild kernels.

891: Both of these trees are a regular CVS checkout. Using these trees it
892: is possible to get a head-start on using the anoncvs servers as
893: described <a href="anoncvs.html">here</a>.

895: results in a much faster initial CVS update than you could expect from
896: a fresh checkout of the full OpenBSD source tree.

912: at this point. This text is not a manual of how to use ports.
913: Rather, it is a set of notes meant to kickstart the user on the
914: OpenBSD ports system.
915: <p>
1.6 schwarze 916: The <i>ports/</i> directory represents a CVS checkout of our ports.
917: As with our complete source tree, our ports tree is available via
1.1 deraadt 918: <a href="anoncvs.html">AnonCVS</a>.
919: So, in order to keep up to date with the <i>-stable</i> branch, you must make
920: the <i>ports/</i> tree available on a read-write medium and update the tree
921: with a command like:
922:
923: <blockquote><pre>
924: # <b>cd /usr/ports</b>
925: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_0</b>
926: </pre></blockquote>
927:
928: [Of course, you must replace the server name here with a nearby anoncvs
929: server.]
930: <p>
931: Note that most ports are available as packages on our mirrors. Updated
932: ports for the 6.0 release will be made available if problems arise.
933: <p>
934: If you're interested in seeing a port added, would like to help out, or just
935: would like to know more, the mailing list
936: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
