9 .TH cupsd.conf 5 "CUPS" "24 April 2018" "Apple Inc."
11 cupsd.conf \- server configuration file for cups
15 file configures the CUPS scheduler,
17 It is normally located in the
20 \fBNote:\fR File, directory, and user configuration directives that used to be allowed in the \fBcupsd.conf\fR file are now stored in the
21 .BR cups-files.conf (5)
22 file instead in order to prevent certain types of privilege escalation attacks.
24 Each line in the file can be a configuration directive, a blank line, or a comment.
25 Configuration directives typically consist of a name and zero or more values separated by whitespace.
26 The configuration directive name and values are case-insensitive.
27 Comment lines start with the # character.
28 .SS TOP-LEVEL DIRECTIVES
29 The following top-level directives are understood by
33 \fBAccessLogLevel config\fR
35 \fBAccessLogLevel actions\fR
37 \fBAccessLogLevel all\fR
38 Specifies the logging level for the AccessLog file.

152 \fBFilterLimit \fIlimit\fR
153 Specifies the maximum cost of filters that are run concurrently, which can be used to minimize disk, memory, and CPU resource problems.
154 A limit of 0 disables filter limiting.
155 An average print to a non-PostScript printer needs a filter limit of about 200.
156 A PostScript printer needs about half that (100).
157 Setting the limit below these thresholds will effectively limit the scheduler to printing a single job at any time.
158 The default limit is "0".
161 \fBFilterNice \fInice-value\fR
162 Specifies the scheduling priority (
164 value) of filters that are run to print a job.
165 The nice value ranges from 0, the highest priority, to 19, the lowest priority.

179 Specifies whether to do reverse lookups on connecting clients.
180 The "Double" setting causes
182 to verify that the hostname resolved from the address matches one of the addresses returned for that hostname.
183 Double lookups also prevent clients with unregistered addresses from connecting to your server.
184 The default is "Off" to avoid the potential server performance problems with hostname lookups.
185 Only set this option to "On" or "Double" if absolutely required.
188 \fBIdleExitTimeout \fIseconds\fR
189 Specifies the length of time to wait before shutting down due to inactivity.

207 \fBJobRetryLimit \fIcount\fR
208 Specifies the number of retries that are done for jobs.
209 This is typically used for fax queues but can also be used with normal print queues whose error policy is "retry-job" or "retry-current-job".
216 Specifies whether to support HTTP keep-alive connections.
217 The default is "Yes".
220 \fBKeepAliveTimeout \fIseconds\fR

250 The Listen directive is similar to the Port directive but allows you to restrict access to specific interfaces or networks.
253 \fBListenBackLog \fInumber\fR
254 Specifies the number of pending connections that will be allowed.
255 This normally only affects very busy servers that have reached the MaxClients limit, but can also be triggered by large numbers of simultaneous connections.
256 When the limit is reached, the operating system will refuse additional connections until the scheduler can accept the pending ones.
257 The default is the OS-defined default limit, typically either "5" for older operating systems or "128" for newer operating systems.
260 \fB<Location \fI/path\fB> \fR... \fB</Location>\fR
261 Specifies access control for the named location.
262 Paths are documented below in the section "LOCATION PATHS".

445 \fBSSLOptions None\fR
446 Sets encryption options (only in /etc/cups/client.conf).
447 By default, CUPS only supports encryption using TLS v1.0 or higher using known secure cipher suites.
448 Security is reduced when \fIAllow\fR options are used.
449 Security is enhanced when \fIDeny\fR options are used.
450 The \fIAllowDH\fR option enables cipher suites using plain Diffie-Hellman key negotiation (not supported on systems using GNU TLS).

837 Sequences beginning with percent (%) characters are replaced with the corresponding information, while all other characters are copied literally.
838 The following percent sequences are recognized:
841 "%%" inserts a single percent character.
842 "%{name}" inserts the value of the specified IPP attribute.
843 "%C" inserts the number of copies for the current page.
844 "%P" inserts the current page number.
845 "%T" inserts the current date and time in common log format.
846 "%j" inserts the job ID.
847 "%p" inserts the printer name.
848 "%u" inserts the username.
851 The default is the empty string, which disables page logging.
852 The string "%p %u %j %T %P %C %{job-billing} %{job-originating-host-name} %{job-name} %{media} %{sides}" creates a page log with the standard items.
853 Use "%{job-impressions-completed}" to insert the number of pages (sides) that were printed, or "%{job-media-sheets-completed}" to insert the number of sheets that were printed.
856 \fBRIPCache \fIsize\fR
857 Specifies the maximum amount of memory to use when converting documents into bitmaps for a printer.
858 The default is "128m".
