Ubuntu Manpage: cups-files.conf - file and directory configuration file for cups

Provided by: cups-daemon_2.1.3-4ubuntu0.11_amd64

NAME

       cups-files.conf - file and directory configuration file for cups

DESCRIPTION

The cups-files.conf file configures the files and directories used by the CUPS scheduler, cupsd(8). It
is normally located in the /etc/cups directory.

Each line in the file can be a configuration directive, a blank line, or a comment. Configuration
directives typically consist of a name and zero or more values separated by whitespace. The
configuration directive name and values are case-insensitive. Comment lines start with the # character.

DIRECTIVES
The following directives are understood by cupsd(8):

AccessLog

AccessLog filename

AccessLog stderr

AccessLog syslog
Defines the access log filename. Specifying a blank filename disables access log generation. The
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. The value
"syslog" causes log entries to be sent to the system log daemon. The server name may be included in
filenames using the string "%s", for example:

AccessLog /var/log/cups/%s-access_log

The default is "/var/log/cups/access_log".

ConfigFilePerm mode
Specifies the permissions for all configuration files that the scheduler writes. The default is
"0644" on OS X and "0640" on all other operating systems.

Note: The permissions for the printers.conf file are currently masked to only allow access from the
scheduler user (typically root). This is done because printer device URIs sometimes contain sensitive
authentication information that should not be generally known on the system. There is no way to disable
this security feature.

DataDir path
Specifies the directory where data files can be found. The default is usually "/usr/share/cups".

DocumentRoot directory
Specifies the root directory for the CUPS web interface content. The default is usually
"/usr/share/doc/cups".

ErrorLog

ErrorLog filename

ErrorLog stderr

ErrorLog syslog
Defines the error log filename. Specifying a blank filename disables error log generation. The
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. The value
"syslog" causes log entries to be sent to the system log daemon. The server name may be included in
filenames using the string "%s", for example:

ErrorLog /var/log/cups/%s-error_log

The default is "/var/log/cups/error_log".

FatalErrors none

FatalErrors all -kind [ ... -kind ]

FatalErrors kind [ ... kind ]
Specifies which errors are fatal, causing the scheduler to exit. The default is "config". The kind
strings are:

none No errors are fatal.

all All of the errors below are fatal.

browse
Browsing initialization errors are fatal, for example failed connections to the DNS-SD daemon.

config
Configuration file syntax errors are fatal.

listen
Listen or Port errors are fatal, except for IPv6 failures on the loopback or "any" addresses.

log Log file creation or write errors are fatal.

permissions
Bad startup file permissions are fatal, for example shared TLS certificate and key files with
world-read permissions.

FileDevice Yes

FileDevice No
Specifies whether the file pseudo-device can be used for new printer queues. The URI
"file:///dev/null" is always allowed.

Group group-name-or-number
Specifies the group name or ID that will be used when executing external programs. The default
group is operating system specific but is usually "lp" or "nobody".

LogFilePerm mode
Specifies the permissions of all log files that the scheduler writes. The default is "0644".

PageLog [ filename ]

PageLog stderr

PageLog syslog
Defines the page log filename. The 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. The value "syslog" causes log entries to be sent to the system log daemon.
Specifying a blank filename disables page log generation. The server name may be included in
filenames using the string "%s", for example:

PageLog /var/log/cups/%s-page_log

The default is "/var/log/cups/page_log".

PassEnv variable [ ... variable ]
Passes the specified environment variable(s) to child processes. Note: the standard CUPS filter and
backend environment variables cannot be overridden using this directive.

RemoteRoot username
Specifies the username that is associated with unauthenticated accesses by clients claiming to be
the root user. The default is "remroot".

RequestRoot directory
Specifies the directory that contains print jobs and other HTTP request data. The default is
"/var/spool/cups".

Sandboxing relaxed

Sandboxing strict
Specifies the level of security sandboxing that is applied to print filters, backends, and other
child processes of the scheduler. The default is "strict". This directive is currently only
used/supported on OS X.

ServerBin directory
Specifies the directory containing the backends, CGI programs, filters, helper programs, notifiers,
and port monitors. The default is "/usr/lib/cups" or "/usr/libexec/cups" depending on the platform.

ServerKeychain path
Specifies the location of TLS certificates and private keys. The default is
"/Library/Keychains/System.keychain" on OS X and "/etc/cups/ssl" on all other operating systems. 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.

ServerRoot directory
Specifies the directory containing the server configuration files. The default is "/etc/cups".

SetEnv variable value
Set the specified environment variable to be passed to child processes. Note: the standard CUPS
filter and backend environment variables cannot be overridden using this directive.

SyncOnClose Yes

SyncOnClose No
Specifies whether the scheduler calls fsync(2) after writing configuration or state files. The
default is "Yes".

SystemGroup group-name [ ... group-name ]
Specifies the group(s) to use for @SYSTEM group authentication. The default contains "admin",
"lpadmin", "root", "sys", and/or "system".

TempDir directory
Specifies the directory where temporary files are stored. The default is "/var/spool/cups/tmp".

User username
Specifies the user name or ID that is used when running external programs. The default is "lp".
