1.3 guenther 214: <li><tt>W^X</tt> is now strictly enforced by default;

218: <a href="http://man.openbsd.org/mount.8">mount(8)</a> option.
1.36 deraadt 219: Because there are still too many ports which violate W^X, the
220: installer mounts the <tt>/usr/local</tt> filesystem with
221: <tt>wxallowed</tt>. This allows the base system to be more
1.37 tb 222: secure as long as <tt>/usr/local</tt> is a separate filesystem.

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

912: To extract:
1.1 deraadt 913:
914: <blockquote><pre>
915: # <b>mkdir -p /usr/src</b>
916: # <b>cd /usr/src</b>

1.6 schwarze 920: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
1.1 deraadt 921: This file contains all the kernel sources you need to rebuild kernels.

950: if you know nothing about ports
951: at this point. This text is not a manual of how to use ports.
952: Rather, it is a set of notes meant to kickstart the user on the
953: OpenBSD ports system.
954: <p>
1.6 schwarze 955: The <i>ports/</i> directory represents a CVS checkout of our ports.
956: As with our complete source tree, our ports tree is available via
1.1 deraadt 957: <a href="anoncvs.html">AnonCVS</a>.
958: So, in order to keep up to date with the <i>-stable</i> branch, you must make
959: the <i>ports/</i> tree available on a read-write medium and update the tree
960: with a command like:
961:
962: <blockquote><pre>
963: # <b>cd /usr/ports</b>
964: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_0</b>

966:
967: [Of course, you must replace the server name here with a nearby anoncvs
968: server.]
969: <p>
970: Note that most ports are available as packages on our mirrors. Updated
971: ports for the 6.0 release will be made available if problems arise.
972: <p>
973: If you're interested in seeing a port added, would like to help out, or just
974: would like to know more, the mailing list
975: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
