15 .TH cupsd.conf 5 "CUPS" "30 June 2015" "Apple Inc."
17 cupsd.conf \- server configuration file for cups
21 file configures the CUPS scheduler,
23 It is normally located in the
26 \fBNote:\fR File, directory, and user configuration directives that used to be allowed in the \fBcupsd.conf\fR file are now stored in the
27 .BR cups-files.conf (5)
28 file instead in order to prevent certain types of privilege escalation attacks.
30 Each line in the file can be a configuration directive, a blank line, or a comment.
31 Configuration directives typically consist of a name and zero or more values separated by whitespace.
32 The configuration directive name and values are case-insensitive.
33 Comment lines start with the # character.
34 .SS TOP-LEVEL DIRECTIVES

46 The "actions" level logs when print jobs are submitted, held, released, modified, or canceled, and any of the conditions for "config".
47 The "all" level logs all requests.
48 The default access log level is "actions".
51 \fBAutoPurgeJobs Yes\fR
53 \fBAutoPurgeJobs No\fR
55 Specifies whether to purge job history data automatically when it is no longer required for quotas.
57 .\"#BrowseLocalProtocols

61 \fBBrowseLocalProtocols dnssd\fR
63 \fBBrowseLocalProtocols none\fR
64 Specifies which protocols to use for local printer sharing.
65 The default is "dnssd" on systems that support Bonjour and "none" otherwise.
72 Specifies whether the CUPS web interface is advertised.
80 Specifies whether shared printers are advertised.
84 \fBClassification \fIbanner\fR
86 Specifies the security classification of the server.
87 Any valid banner name can be used, including "classified", "confidential", "secret", "topsecret", and "unclassified", or the banner can be omitted to disable secure printing functions.
88 The default is no classification banner.
91 \fBClassifyOverride Yes\fR
93 \fBClassifyOverride No\fR
95 Specifies whether users may override the classification (cover page) of individual print jobs using the "job-sheets" option.
99 \fBDefaultAuthType Basic\fR
101 \fBDefaultAuthType Negotiate\fR
103 Specifies the default type of authentication to use.

141 .\"#DirtyCleanInterval
143 \fBDirtyCleanInterval \fIseconds\fR
144 Specifies the delay for updating of configuration and state files.
145 A value of 0 causes the update to happen as soon as possible, typically within a few milliseconds.
146 The default value is "30".
149 \fBErrorPolicy abort-job\fR
150 Specifies that a failed print job should be aborted (discarded) unless otherwise specified for the printer.
152 \fBErrorPolicy retry-job\fR
153 Specifies that a failed print job should be retried at a later time unless otherwise specified for the printer.

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

184 \fBHostNameLookups On\fR
186 \fBHostNameLookups Off\fR
188 \fBHostNameLookups Double\fR
189 Specifies whether to do reverse lookups on connecting clients.
190 The "Double" setting causes
192 to verify that the hostname resolved from the address matches one of the addresses returned for that hostname.
193 Double lookups also prevent clients with unregistered addresses from connecting to your server.
194 The default is "Off" to avoid the potential server performance problems with hostname lookups.
195 Only set this option to "On" or "Double" if absolutely required.
198 \fBJobKillDelay \fIseconds\fR
199 Specifies the number of seconds to wait before killing the filters and backend associated with a canceled or held job.
203 \fBJobRetryInterval \fIseconds\fR

209 \fBJobRetryLimit \fIcount\fR
210 Specifies the number of retries that are done for jobs.
211 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".
218 Specifies whether to support HTTP keep-alive connections.
219 The default is "Yes".
222 \fBKeepAliveTimeout \fIseconds\fR
223 Specifies how long an idle client connection remains open.

235 Specifies the HTTP methods that are being limited inside a Location section. HTTP method names are listed below in the section "HTTP METHODS".
238 \fBLimitRequestBody \fIsize\fR
239 Specifies the maximum size of print files, IPP requests, and HTML form data.
240 The default is "0" which disables the limit check.
243 \fBListen \fIipv4-address\fB:\fIport\fR
245 \fBListen [\fIipv6-address\fB]:\fIport\fR
247 \fBListen *:\fIport\fR
249 \fBListen \fI/path/to/domain/socket\fR
250 Listens to the specified address and port or domain socket path for connections.
251 Multiple Listen directives can be provided to listen on multiple addresses.
252 The Listen directive is similar to the Port directive but allows you to restrict access to specific interfaces or networks.
255 \fBListenBackLog \fInumber\fR
256 Specifies the number of pending connections that will be allowed.
257 This normally only affects very busy servers that have reached the MaxClients limit, but can also be triggered by large numbers of simultaneous connections.
258 When the limit is reached, the operating system will refuse additional connections until the scheduler can accept the pending ones.
259 The default is the OS-defined default limit, typically either "5" for older operating systems or "128" for newer operating systems.

367 "%j" inserts the job ID.
368 "%p" inserts the printer name.

428 Using the special name "*" can expose your system to known browser-based DNS rebinding attacks, even when accessing sites through a firewall.
429 If the auto-discovery of alternate names does not work, we recommend listing each alternate name with a ServerAlias directive instead of using "*".
432 \fBServerName \fIhostname\fR
433 Specifies the fully-qualified hostname of the server.
434 The default is the value reported by the
439 \fBServerTokens None\fR
