209: <ul>
1.3 guenther 210: <li><tt>W^X</tt> is now strictly enforced by default;
211: a program can only violate it if the executable is marked with

1.6 schwarze 213: mounted with the <tt>wxallowed</tt>
214: <a href="http://man.openbsd.org/mount.8">mount(8)</a> option.
1.36 deraadt 215: Because there are still too many ports which violate W^X, the
216: installer mounts the <tt>/usr/local</tt> filesystem with
217: <tt>wxallowed</tt>. This allows the base system to be more
1.37 tb 218: secure as long as <tt>/usr/local</tt> is a separate filesystem.
1.36 deraadt 219: If you use no W^X violating programs, consider manually

242: change the size of the hash array now.

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

910: <blockquote><pre>
911: # <b>mkdir -p /usr/src</b>
912: # <b>cd /usr/src</b>

947: at this point. This text is not a manual of how to use ports.
948: Rather, it is a set of notes meant to kickstart the user on the
949: OpenBSD ports system.
950: <p>
1.6 schwarze 951: The <i>ports/</i> directory represents a CVS checkout of our ports.
952: As with our complete source tree, our ports tree is available via
1.1 deraadt 953: <a href="anoncvs.html">AnonCVS</a>.
954: So, in order to keep up to date with the <i>-stable</i> branch, you must make
955: the <i>ports/</i> tree available on a read-write medium and update the tree
956: with a command like:
957:
958: <blockquote><pre>
959: # <b>cd /usr/ports</b>
960: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_0</b>

962:
963: [Of course, you must replace the server name here with a nearby anoncvs
964: server.]
965: <p>
966: Note that most ports are available as packages on our mirrors. Updated
967: ports for the 6.0 release will be made available if problems arise.
968: <p>
969: If you're interested in seeing a port added, would like to help out, or just
970: would like to know more, the mailing list
971: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
