On UNIX, Linux, and Mac OS X, you will find the configuration in the file <em>/etc/syslog.conf</em>, or in <em>/etc/rsyslog.conf</em> or in the directory <em>/etc/rsyslog.d</em>. These files define the routing configuration. Messages can be flagged with the codes <code>LOG_LOCAL0</code> through <code>LOG_LOCAL7</code>. For information on Syslog facilities, severity levels, and how to set up <em>syslog.conf</em> or <em>rsyslog.conf</em>, see the <em>syslog.conf</em> or <em>rsyslog.conf</em> manual page on your command line.
