NAME
       client.conf - client configuration file for cups (deprecated on macos)

DESCRIPTION
       The client.conf file configures the CUPS client and is normally located
       in the /etc/cups and/or ~/.cups directories.  Each line in the file can
       be a configuration directive, a blank line, or a comment. Comment lines
       start with the # character.

       Note:  Starting with macOS 10.7, this file is only used by command-line
       and X11 applications plus the IPP backend.  The ServerName directive is
       not supported on macOS at all.  Starting with macOS 10.12, all applica‐
       tions   can   access   these   settings   in    the    /Library/Prefer‐
       ences/org.cups.PrintingPrefs.plist file instead.  See the NOTES section
       below for more information.

   DIRECTIVES
       The  following directives are understood by the client. Consult the on‐
       line help for detailed descriptions:

       AllowAnyRoot Yes

       AllowAnyRoot No
            Specifies whether to allow TLS with  certificates  that  have  not
            been  signed  by  a trusted Certificate Authority.  The default is
            "Yes".

       AllowExpiredCerts Yes

       AllowExpiredCerts No
            Specifies whether to allow TLS with expired certificates.  The de‐
            fault is "No".

       DigestOptions DenyMD5

       DigestOptions None
            Specifies HTTP Digest authentication  options.   DenyMD5  disables
            support for the original MD5 hash algorithm.

       Encryption IfRequested

       Encryption Never

       Encryption Required
            Specifies the level of encryption that should be used.

       GSSServiceName name
            Specifies  the  Kerberos service name that is used for authentica‐
            tion, typically "host", "http", or "ipp".  CUPS  adds  the  remote
            hostname  ("name@server.example.com") for you. The default name is
            "http".

       ServerName hostname-or-ip-address[:port]

       ServerName /domain/socket
            Specifies the address and optionally the port to use when connect‐
            ing to the server.  Note: This directive is not supported on macOS
            10.7 or later.

       ServerName hostname-or-ip-address[:port]/version=1.1
            Specifies the address and optionally the port to use when connect‐
            ing to a server running CUPS 1.3.12 and earlier.

       SSLOptions [AllowDH] [AllowRC4] [AllowSSL3] [DenyCBC] [DenyTLS1.0]
       [MaxTLS1.0] [MaxTLS1.1] [MaxTLS1.2] [MaxTLS1.3] [MinTLS1.0] [MinTLS1.1]
       [MinTLS1.2] [MinTLS1.3] [NoSystem]

       SSLOptions None
            Sets encryption options (only in /etc/cups/client.conf).   By  de‐
            fault,  CUPS only supports encryption using TLS v1.0 or higher us‐
            ing known secure cipher suites.  Security is  reduced  when  Allow
            options  are  used.   Security  is  enhanced when Deny options are
            used.  The  AllowDH  option  enables  cipher  suites  using  plain
            Diffie-Hellman key negotiation (not supported on systems using GNU
            TLS).   The AllowRC4 option enables the 128-bit RC4 cipher suites,
            which are required for some older clients.  The  AllowSSL3  option
            enables SSL v3.0, which is required for some older clients that do
            not  support TLS v1.0.  The DenyCBC option disables all CBC cipher
            suites.  The DenyTLS1.0 option disables TLS v1.0  support  -  this
            sets the minimum protocol version to TLS v1.1.  The MinTLS options
            set  the  minimum  TLS version to support.  The MaxTLS options set
            the maximum TLS version to support.  The NoSystem option  disables
            applying  system  cryptographic policy.  Not all operating systems
            support TLS 1.3 at this time.

       TrustOnFirstUse Yes

       TrustOnFirstUse No
            Specifies whether to trust new TLS certificates by  default.   The
            default is "Yes".

       User name
            Specifies the default user name to use for requests.

       UserAgentTokens None

       UserAgentTokens ProductOnly

       UserAgentTokens Major

       UserAgentTokens Minor

       UserAgentTokens Minimal

       UserAgentTokens OS

       UserAgentTokens Full
            Specifies what information is included in the User-Agent header of
            HTTP  requests.   "None" disables the User-Agent header.  "Produc‐
            tOnly" reports "CUPS".  "Major" reports "CUPS/major IPP/2".   "Mi‐
            nor"   reports   "CUPS/major.minor  IPP/2.1".   "Minimal"  reports
            "CUPS/major.minor.patch IPP/2.1".   "OS"  reports  "CUPS/major.mi‐
            nor.path  (osname  osversion)  IPP/2.1".  "Full" reports "CUPS/ma‐
            jor.minor.path (osname osversion; architecture) IPP/2.1".  The de‐
            fault is "Minimal".

       ValidateCerts Yes

       ValidateCerts No
            Specifies whether to only allow TLS with certificates whose common
            name matches the hostname.  The default is "No".


ATTRIBUTES
       See attributes(7) for descriptions of the following attributes:

       box; cbp-1 | cbp-1 l | l .  ATTRIBUTE TYPE ATTRIBUTE VALUE = Availabil‐
       ity   print/cups = Stability Volatile

NOTES
       The client.conf file is deprecated on macOS and will no longer be  sup‐
       ported in a future version of CUPS.  Configuration settings can instead
       be viewed or changed using the defaults(1) command:
       defaults write /Library/Preferences/org.cups.PrintingPrefs.plist Encryption Required
       defaults write /Library/Preferences/org.cups.PrintingPrefs.plist TrustOnFirstUse -bool NO

       defaults read /Library/Preferences/org.cups.PrintingPrefs.plist Encryption
       On  Linux  and  other systems using GNU TLS, the /etc/cups/ssl/site.crl
       file, if present, provides a list of revoked X.509 certificates and  is
       used when validating certificates.
