17 cups\-files.conf \- file and directory configuration file for cups
19 The \fBcups\-files.conf\fR file configures the files and directories used by the CUPS scheduler,
21 It is normally located in the \fI/etc/cups\fR directory.
23 Each line in the file can be a configuration directive, a blank line, or a comment.
24 Configuration directives typically consist of a name and zero or more values separated by whitespace.
25 The configuration directive name and values are case-insensitive.
26 Comment lines start with the # character.
28 The following directives are understood by
34 \fBAccessLog \fIfilename\fR
36 \fBAccessLog syslog\fR
37 Defines the access log filename.
38 Specifying a blank filename disables access log generation.
39 The value "syslog" causes log entries to be sent to the system log daemon.
40 The server name may be included in filenames using the string "%s", for example:
43 AccessLog /var/log/cups/%s-access_log
46 The default is "/var/log/cups/access_log".
49 \fBConfigFilePerm \fImode\fR
50 Specifies the permissions for all configuration files that the scheduler writes.
51 The default is "0644" on OS X and "0640" on all other operating systems.
53 \fBNote:\fR The permissions for the \fIprinters.conf\fR file are currently masked to only allow access from the scheduler user (typically root).
54 This is done because printer device URIs sometimes contain sensitive authentication information that should not be generally known on the system.
55 There is no way to disable this security feature.
59 Specifies the directory where data files can be found.
60 The default is usually "/usr/share/cups".
63 \fBDocumentRoot \fIdirectory\fR
64 Specifies the root directory for the CUPS web interface content.
65 The default is usually "/usr/share/doc/cups".
70 \fBErrorLog \fIfilename\fR
73 Defines the error log filename.
74 Specifying a blank filename disables error log generation.
75 The value "syslog" causes log entries to be sent to the system log daemon.
76 The server name may be included in filenames using the string "%s", for example:
79 ErrorLog /var/log/cups/%s-error_log
82 The default is "/var/log/cups/error_log".
85 \fBFatalErrors none\fR
87 \fBFatalErrors all \fI\-kind \fR[ ... \fI\-kind \fR]
89 \fBFatalErrors \fIkind \fR[ ... \fIkind \fR]
90 Specifies which errors are fatal, causing the scheduler to exit.
91 The default is "config".
92 The \fIkind\fR strings are:
99 All of the errors below are fatal.
102 Browsing initialization errors are fatal, for example failed connections to the DNS-SD daemon.
105 Configuration file syntax errors are fatal.
108 Listen or Port errors are fatal, except for IPv6 failures on the loopback or "any" addresses.
111 Log file creation or write errors are fatal.
114 Bad startup file permissions are fatal, for example shared TLS certificate and key files with world-read permissions.
121 Specifies whether the file pseudo-device can be used for new printer queues.
122 The URI "file:///dev/null" is always allowed.
125 \fBGroup \fIgroup-name-or-number\fR
126 Specifies the group name or ID that will be used when executing external programs.
127 The default group is operating system specific but is usually "lp" or "nobody".
130 \fBLogFilePerm \fImode\fR
131 Specifies the permissions of all log files that the scheduler writes.
132 The default is "0644".
135 \fBPageLog \fR[ \fIfilename\fR ]
138 Defines the page log filename.
139 The value "syslog" causes log entries to be sent to the system log daemon.
140 Specifying a blank filename disables page log generation.
141 The server name may be included in filenames using the string "%s", for example:
144 PageLog /var/log/cups/%s-page_log
147 The default is "/var/log/cups/page_log".
150 \fBRemoteRoot \fIusername\fR
151 Specifies the username that is associated with unauthenticated accesses by clients claiming to be the root user.
152 The default is "remroot".
155 \fBRequestRoot \fIdirectory\fR
156 Specifies the directory that contains print jobs and other HTTP request data.
157 The default is "/var/spool/cups".
160 \fBSandboxing relaxed\fR
162 \fBSandboxing strict\fR
163 Specifies the level of security sandboxing that is applied to print filters, backends, and other child processes of the scheduler.
164 The default is "strict".
165 This directive is currently only used/supported on OS X.
168 \fBServerBin \fIdirectory\fR
169 Specifies the directory containing the backends, CGI programs, filters, helper programs, notifiers, and port monitors.
170 The default is "/usr/lib/cups" or "/usr/libexec/cups" depending on the platform.
173 \fBServerKeychain \fIpath\fR
174 Specifies the location of TLS certificates and private keys.
175 The default is "/Library/Keychains/System.keychain" on OS X and "/etc/cups/ssl" on all other operating systems.
176 OS X uses its keychain database to store certificates and keys while other platforms use separate files in the specified directory, *.crt for PEM-encoded certificates and *.key for PEM-encoded private keys.
179 \fBServerRoot \fIdirectory\fR
180 Specifies the directory containing the server configuration files.
181 The default is "/etc/cups".
184 \fBSyncOnClose Yes\fR
187 Specifies whether the scheduler calls
189 after writing configuration or state files.
193 \fBSystemGroup \fIgroup-name \fR[ ... \fIgroup-name\fR ]
194 Specifies the group(s) to use for \fI@SYSTEM\fR group authentication.
195 The default contains "admin", "lpadmin", "root", "sys", and/or "system".

203 \fBUser \fIusername\fR
204 Specifies the user name or ID that is used when running external programs.
