197: <ul>
1.3 guenther 198: <li><tt>W^X</tt> is now strictly enforced by default;
199: a program can only violate it if the executable is marked with
1.38 tb 200: <tt>PT_OPENBSD_WXNEEDED</tt> and is located on a filesystem
1.6 schwarze 201: mounted with the <tt>wxallowed</tt>
202: <a href="http://man.openbsd.org/mount.8">mount(8)</a> option.
1.36 deraadt 203: Because there are still too many ports which violate W^X, the
204: installer mounts the <tt>/usr/local</tt> filesystem with
205: <tt>wxallowed</tt>. This allows the base system to be more
1.37 tb 206: secure as long as <tt>/usr/local</tt> is a separate filesystem.
1.36 deraadt 207: If you use no W^X violating programs, consider manually

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

867: This file contains everything you need except for the kernel sources,
868: which are in a separate archive.
869: To extract:
1.1 deraadt 870:
871: <blockquote><pre>
872: # <b>mkdir -p /usr/src</b>
873: # <b>cd /usr/src</b>
874: # <b>tar xvfz /tmp/src.tar.gz</b>
875: </pre></blockquote>
876:
1.6 schwarze 877: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
1.1 deraadt 878: This file contains all the kernel sources you need to rebuild kernels.
879: To extract:
880:
881: <blockquote><pre>
882: # <b>mkdir -p /usr/src/sys</b>
883: # <b>cd /usr/src</b>
884: # <b>tar xvfz /tmp/sys.tar.gz</b>
885: </pre></blockquote>

887: Both of these trees are a regular CVS checkout. Using these trees it
888: is possible to get a head-start on using the anoncvs servers as
889: described <a href="anoncvs.html">here</a>.
890: Using these files
891: results in a much faster initial CVS update than you could expect from
892: a fresh checkout of the full OpenBSD source tree.

906: Go read the <a href="faq/ports/index.html">ports</a> page
907: if you know nothing about ports
908: at this point. This text is not a manual of how to use ports.
909: Rather, it is a set of notes meant to kickstart the user on the
910: OpenBSD ports system.
911: <p>
1.6 schwarze 912: The <i>ports/</i> directory represents a CVS checkout of our ports.
913: As with our complete source tree, our ports tree is available via
1.1 deraadt 914: <a href="anoncvs.html">AnonCVS</a>.
915: So, in order to keep up to date with the <i>-stable</i> branch, you must make
916: the <i>ports/</i> tree available on a read-write medium and update the tree
917: with a command like:
918:
919: <blockquote><pre>
920: # <b>cd /usr/ports</b>
921: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_0</b>
922: </pre></blockquote>
923:
924: [Of course, you must replace the server name here with a nearby anoncvs
925: server.]
926: <p>
927: Note that most ports are available as packages on our mirrors. Updated
928: ports for the 6.0 release will be made available if problems arise.
929: <p>
930: If you're interested in seeing a port added, would like to help out, or just
931: would like to know more, the mailing list
932: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
