9 .TH cupsd.conf 5 "CUPS" "3 November 2017" "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

51 .\"#BrowseDNSSDSubTypes
53 .BI BrowseDNSSDSubTypes _subtype[,...]
54 Specifies a list of Bonjour sub-types to advertise for each shared printer.
55 For example, "BrowseDNSSDSubTypes _cups,_print" will tell network clients that both CUPS sharing and IPP Everywhere are supported.
56 The default is "_cups" which is necessary for printer sharing to work between systems using CUPS.

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.

174 \fBHostNameLookups On\fR
176 \fBHostNameLookups Off\fR
178 \fBHostNameLookups Double\fR
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.

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
221 Specifies how long an idle client connection remains open.

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".
