CHANGES IN CUPS V1.6.2
- Documentation fixes
+ - Security: All file, directory, user, and group settings are now stored
+ in a separate cups-files.conf configuration file that cannot be set
+ through the CUPS web interface or APIs (STR #4223)
- The SNMP backend now tries to work around broken printers that use a
newline to separate key/value pairs.
- The IPP backend did not send a cancel request to printers when a job

cups-files.conf
+
+
The /etc/cups/cups-files.conf file contains configuration directives that control the files, directories. users. and groups that are used by the CUPS scheduler, cupsd(8). Each directive is listed on a line by itself followed by its value. Comments are introduced using the number sign ("#") character at the beginning of a line.
The AccessLog directive sets the name of the
+access log file. If the filename is not absolute then it is
+assumed to be relative to the ServerRoot directory. The
+access log file is stored in "common log format" and can be used
+by any web access reporting tool to generate a report on CUPS
+server activity.
+
+
The server name can be included in the filename by using
+%s in the name.
+
+
The special name "syslog" can be used to send the access
+information to the system log instead of a plain file.
+
+
The default access log file is
+@CUPS_LOGDIR@/access_log.
The ConfigFilePerm directive specifies the permissions to use when the scheduler writes configuration and cache files, typically in response to IPP or HTTP requests. The default is @CUPS_CONFIG_FILE_PERM@.
+
+
Note:
+
+
The permissions for the printers.conf file are always 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.
The DocumentRoot directive specifies the location
+of web content for the HTTP server in CUPS. If an absolute path
+is not specified then it is assumed to be relative to the ServerRoot directory. The
+default directory is @CUPS_DOCROOT@.
+
+
Documents are first looked up in a sub-directory for the
+primary language requested by the client (e.g.
+@CUPS_DOCROOT@/fr/...) and then directly under
+the DocumentRoot directory (e.g.
+@CUPS_DOCROOT@/...), so it is possible to
+localize the web content by providing subdirectories for each
+language needed.
The ErrorLog directive sets the name of the error
+log file. If the filename is not absolute then it is assumed to
+be relative to the ServerRoot directory. The
+default error log file is @CUPS_LOGDIR@/error_log.
+
+
The server name can be included in the filename by using
+%s in the name.
+
+
The special name "syslog" can be used to send the error
+information to the system log instead of a plain file.
The FatalErrors directive determines whether certain kinds of
+errors are fatal. The following kinds of errors are currently recognized:
+
+
+
+
none - No errors are fatal
+
+
all - All of the errors below are fatal
+
+
browse - Browsing initialization errors are fatal,
+ for example failed binding to the CUPS browse port or failed connections
+ to LDAP servers
+
+
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 SSL certificate and key files with world-
+ read permissions
+
+
+
+
Multiple errors can be listed, and the form "-kind" can be used with
+all to remove specific kinds of errors. The default setting is
+@CUPS_FATAL_ERRORS@.
The FileDevice directive determines whether the
+scheduler allows new printers to be added using device URIs of
+the form file:/filename. File devices are most often
+used to test new printer drivers and do not support raw file
+printing.
+
+
The default setting is No.
+
+
Note:
+
+
File devices are managed by the scheduler. Since the
+scheduler normally runs as the root user, file devices
+can be used to overwrite system files and potentially
+gain unauthorized access to the system. If you must
+create printers using file devices, we recommend that
+you set the FileDevice directive to
+Yes for only as long as you need to add the
+printers to the system, and then reset the directive to
+No.
The PageLog directive sets the name of the page
+log file. If the filename is not absolute then it is assumed to
+be relative to the ServerRoot directory. The
+default page log file is @CUPS_LOGDIR@/page_log.
+
+
The server name can be included in the filename by using
+%s in the name.
+
+
The special name "syslog" can be used to send the page
+information to the system log instead of a plain file.
The Printcap directive controls whether or not a
+printcap file is automatically generated and updated with a list
+of available printers. If specified with no value, then no
+printcap file will be generated. The default is to generate a
+file named @CUPS_DEFAULT_PRINTCAP@.
+
+
When a filename is specified (e.g. @CUPS_DEFAULT_PRINTCAP@),
+the printcap file is written whenever a printer is added or
+removed. The printcap file can then be used by applications that
+are hardcoded to look at the printcap file for the available
+printers.
+PrintcapFormat BSD
+PrintcapFormat Solaris
+PrintcapFormat plist
+
+
+
Description
+
+
The PrintcapFormat directive controls the output format of the
+printcap file. The default is to generate the plist format on OS X, the
+Solaris format on Solaris, and the BSD format on other operating systems.
The RemoteRoot directive sets the username for
+unauthenticated root requests from remote hosts. The default
+username is remroot. Setting RemoteRoot
+to root effectively disables this security
+mechanism.
The RequestRoot directive sets the directory for
+incoming IPP requests and HTML forms. If an absolute path is not
+provided then it is assumed to be relative to the ServerRoot directory. The
+default request directory is @CUPS_REQUESTS@.
The ServerBin directive sets the directory for
+server-run executables. If an absolute path is not provided then
+it is assumed to be relative to the ServerRoot directory. The
+default executable directory is /usr/lib/cups,
+/usr/lib32/cups, or /usr/libexec/cups
+depending on the operating system.
The ServerCertificate directive specifies the
+location of the SSL certificate file used by the server when
+negotiating encrypted connections. The certificate must not be
+encrypted (password protected) since the scheduler normally runs
+in the background and will be unable to ask for a password.
+
+
The default certificate file is
+/etc/cups/ssl/server.crt.
The ServerRoot directive specifies the absolute
+path to the server configuration and state files. It is also used
+to resolve relative paths in the cupsd.conf file. The
+default server directory is /etc/cups.
The SystemGroup directive specifies the system
+administration group for System authentication.
+Multiple groups can be listed, separated with spaces. The default
+group list is @CUPS_SYSTEM_GROUPS@.
The TempDir directive specifies an absolute path
+for the directory to use for temporary files. The default
+directory is @CUPS_REQUESTS@/tmp.
+
+
Temporary directories must be world-writable and should have
+the "sticky" permission bit enabled so that other users cannot
+delete filter temporary files. The following commands will create
+an appropriate temporary directory called
+/foo/bar/tmp:
The User directive specifies the UNIX user that
+filter and CGI programs run as. The default user is
+@CUPS_USER@.
+
+
Note:
+
+
You may not use user root, as that would expose
+the system to unacceptable security risks. The scheduler will
+automatically choose user nobody if you specify a
+user whose ID is 0.

- AuthClass Anonymous
- AuthClass User
- AuthClass System
- AuthClass Group
-</Location>
-
-
-
Description
-
-
The AuthClass directive defines what level of
-authentication is required:
-
-
-
-
Anonymous - No authentication should be
- performed (default)
-
-
User - A valid username and password is
- required
-
-
System - A valid username and password
- is required, and the username must belong to the "sys"
- group; this can be changed using the SystemGroup
- directive
-
-
Group - A valid username and password is
- required, and the username must belong to the group named
- by the AuthGroupName
- directive
-
-
-
-
The AuthClass directive must appear inside a Location or Limit section.
-
-
This directive is deprecated and will be removed from a
-future release of CUPS. Consider using the more flexible Require directive instead.
The Printcap directive controls whether or not a
-printcap file is automatically generated and updated with a list
-of available printers. If specified with no value, then no
-printcap file will be generated. The default is to generate a
-file named @CUPS_DEFAUL_PRINTCAP@.
-
-
When a filename is specified (e.g. @CUPS_DEFAULT_PRINTCAP@),
-the printcap file is written whenever a printer is added or
-removed. The printcap file can then be used by applications that
-are hardcoded to look at the printcap file for the available
-printers.
-PrintcapFormat BSD
-PrintcapFormat Solaris
-PrintcapFormat plist
-
-
-
Description
-
-
The PrintcapFormat directive controls the output format of the
-printcap file. The default is to generate the plist format on OS X, the
-Solaris format on Solaris, and the BSD format on other operating systems.
The RemoteRoot directive sets the username for
-unauthenticated root requests from remote hosts. The default
-username is remroot. Setting RemoteRoot
-to root effectively disables this security
-mechanism.
The RequestRoot directive sets the directory for
-incoming IPP requests and HTML forms. If an absolute path is not
-provided then it is assumed to be relative to the ServerRoot directory. The
-default request directory is @CUPS_REQUESTS@.
The ServerBin directive sets the directory for
-server-run executables. If an absolute path is not provided then
-it is assumed to be relative to the ServerRoot directory. The
-default executable directory is /usr/lib/cups,
-/usr/lib32/cups, or /usr/libexec/cups
-depending on the operating system.
The ServerCertificate directive specifies the
-location of the SSL certificate file used by the server when
-negotiating encrypted connections. The certificate must not be
-encrypted (password protected) since the scheduler normally runs
-in the background and will be unable to ask for a password.
-
-
The default certificate file is
-/etc/cups/ssl/server.crt.
The ServerRoot directive specifies the absolute
-path to the server configuration and state files. It is also used
-to resolve relative paths in the cupsd.conf file. The
-default server directory is /etc/cups.
The SystemGroup directive specifies the system
-administration group for System authentication.
-Multiple groups can be listed, separated with spaces. The default
-group list is @CUPS_SYSTEM_GROUPS@.
The TempDir directive specifies an absolute path
-for the directory to use for temporary files. The default
-directory is @CUPS_REQUESTS@/tmp.
-
-
Temporary directories must be world-writable and should have
-the "sticky" permission bit enabled so that other users cannot
-delete filter temporary files. The following commands will create
-an appropriate temporary directory called
-/foo/bar/tmp:
The UseNetworkDefault directive controls whether
-the client will use a network/remote printer as a default
-printer. If enabled, the default printer of a server is used as
-the default printer on a client. When multiple servers are
-advertising a default printer, the client's default printer is
-set to the first discovered printer, or to the implicit class for
-the same printer available from multiple servers.
The User directive specifies the UNIX user that
-filter and CGI programs run as. The default user is
-@CUPS_USER@.
-
-
Note:
-
-
You may not use user root, as that would expose
-the system to unacceptable security risks. The scheduler will
-automatically choose user nobody if you specify a
-user whose ID is 0.
