name="DESCRIPTION">Description</a></h2> 13The <b>cups-files.conf</b> file configures the files and directories used by the CUPS scheduler, 14<b>cupsd</b>(8). 15It is normally located in the <i>/etc/cups</i> directory. 16<p>Each line in the file can be a configuration directive, a blank line, or a comment. 17Configuration directives typically consist of a name and zero or more values separated by whitespace. 18The configuration directive name and values are case-insensitive. 19Comment lines start with the # character. 20<h3><a name="DIRECTIVES">Directives</a></h3> 21The following directives are understood by 22<b>cupsd</b>(8): 23<dl class="man"> 24<dt><a name="AccessLog"></a><b>AccessLog</b> 25<dd style="margin-left: 5.0em"><dt><b>AccessLog </b><i>filename</i> 26<dd style="margin-left: 5.0em"><dt><b>AccessLog stderr</b> 27<dd style="margin-left: 5.0em"><dt><b>AccessLog syslog</b> 28<dd style="margin-left: 5.0em">Defines the access log filename. 29Specifying a blank filename disables access log generation. 30The value "stderr" causes log entries to be sent to the standard error file when the scheduler is running in the foreground, or to the system log daemon when run in the background. 31The value "syslog" causes log entries to be sent to the system log daemon. 32The server name may be included in filenames using the string "%s", for example: 33<pre class="man"> 34 35 AccessLog /var/log/cups/%s-access_log 36 37</pre> 38The default is "/var/log/cups/access_log". 39<dt><a name="CacheDir"></a><b>CacheDir </b><i>directory</i> 40<dd style="margin-left: 5.0em">Specifies the directory to use for long-lived temporary (cache) files. 41The default is "/var/spool/cups/cache" or "/var/cache/cups" depending on the platform. 42<dt><a

macOS and "0640" on all other operating systems. 45</dl> 46<p><b>Note:</b> The permissions for the <i>printers.conf</i> file are currently masked to only allow access from the scheduler user (typically root). 47This is done because printer device URIs sometimes contain sensitive authentication information that should not be generally known on the system. 48There is no way to disable this security feature. 49<dl class="man"> 50<dt><a name="CreateSelfSignedCerts"></a><b>CreateSelfSignedCerts yes</b> 51<dd style="margin-left: 5.0em"><dt><b>CreateSelfSignedCerts no</b> 52<dd

to be sent to the standard error file when the scheduler is running in the foreground, or to the system log daemon when run in the background. 67The value "syslog" causes log entries to be sent to the system log daemon. 68The server name may be included in filenames using the string "%s", for example: 69<pre class="man"> 70 71 ErrorLog /var/log/cups/%s-error_log 72 73</pre> 74The default is
