NAME

       client.conf - client configuration file for cups (deprecated)

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 OS X 10.7, this file is only used by command-line and X11 applications
       plus the IPP backend.  The ServerName directive is not supported on OS X at all.

   DIRECTIVES
       The following directives are understood  by  the  client.  Consult  the  online  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 default is "Yes".

       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  authentication,  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 connecting to  the  server.
            Note: This directive it not supported on OS X 10.7 or later.

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

       SSLOptions [AllowDH] [AllowRC4] [AllowSSL3] [DenyTLS1.0]

       SSLOptions None
            Sets encryption options (only  in  /etc/cups/client.conf).   By  default,  CUPS  only
            supports  encryption  using TLS v1.0 or higher using known secure cipher suites.  The
            AllowDH option enables cipher suites using plain Diffie-Hellman key negotiation.  The
            AllowRC4  option  enables  the 128-bit RC4 cipher suites, which are required for some
            older clients that do not implement newer ones.  The  AllowSSL3  option  enables  SSL
            v3.0,  which  is  required  for some older clients that do not support TLS v1.0.  The
            DenyTLS1.0 option disables TLS v1.0 support - this sets the minimum protocol  version
            to TLS v1.1.

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

       ValidateCerts Yes

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

NOTES

       The client.conf file is deprecated and will no longer be supported in a future version  of
       CUPS.
