NAME

       testparm - check an smb.conf configuration file for internal correctness

SYNOPSIS

       testparm [-s|--suppress-prompt] [-v|--verbose] [-?|--help] [--usage]
        [-d|--debuglevel=DEBUGLEVEL] [--debug-stdout] {config filename} [hostname hostIP]

DESCRIPTION

       This tool is part of the samba(7) suite.

       testparm is a very simple test program to check an smbd(8) configuration file for internal
       correctness. If this program reports no problems, you can use the configuration file with
       confidence that smbd will successfully load the configuration file.

       Note that this is NOT a guarantee that the services specified in the configuration file
       will be available or will operate as expected.

       If the optional host name and host IP address are specified on the command line, this test
       program will run through the service entries reporting whether the specified host has
       access to each service.

       If testparm finds an error in the smb.conf file it returns an exit code of 1 to the
       calling program, else it returns an exit code of 0. This allows shell scripts to test the
       output from testparm.

OPTIONS

       -s|--suppress-prompt
           Without this option, testparm will prompt for a carriage return after printing the
           service names and before dumping the service definitions.

       -v|--verbose
           If this option is specified, testparm will also output all options that were not used
           in smb.conf(5) and are thus set to their defaults.

       --parameter-name parametername
           Dumps the named parameter. If no section-name is set the view is limited by default to
           the global section. It is also possible to dump a parametrical option. Therefore the
           option has to be separated by a colon from the parametername.

       --section-name sectionname
           Dumps the named section.

       --show-all-parameters
           Show the parameters, type, possible values.

       -l|--skip-logic-checks
           Skip the global checks.

       -?|--help
           Print a summary of command line options.

       --usage
           Display brief usage message.

       -d|--debuglevel=DEBUGLEVEL
           level is an integer from 0 to 10. The default value if this parameter is not specified
           is 1 for client applications.

           The higher this value, the more detail will be logged to the log files about the
           activities of the server. At level 0, only critical errors and serious warnings will
           be logged. Level 1 is a reasonable level for day-to-day running - it generates a small
           amount of information about operations carried out.

           Levels above 1 will generate considerable amounts of log data, and should only be used
           when investigating a problem. Levels above 3 are designed for use only by developers
           and generate HUGE amounts of log data, most of which is extremely cryptic.

           Note that specifying this parameter here will override the log level parameter in the
           /etc/samba/smb.conf file.

       --debug-stdout
           This will redirect debug output to STDOUT. By default all clients are logging to
           STDERR.

       --configfile=<configuration file>
           The file specified contains the configuration details required by the client. The
           information in this file can be general for client and server or only provide client
           specific like options such as client smb encrypt. See /etc/samba/smb.conf for more
           information. The default configuration file name is determined at compile time.

       --option=<name>=<value>
           Set the smb.conf(5) option "<name>" to value "<value>" from the command line. This
           overrides compiled-in defaults and options read from the configuration file. If a name
           or a value includes a space, wrap whole --option=name=value into quotes.

       -V|--version
           Prints the program version number.

       configfilename
           This is the name of the configuration file to check. If this parameter is not present
           then the default smb.conf(5) file will be checked.

       hostname
           If this parameter and the following are specified, then testparm will examine the
           hosts allow and hosts deny parameters in the smb.conf(5) file to determine if the
           hostname with this IP address would be allowed access to the smbd server. If this
           parameter is supplied, the hostIP parameter must also be supplied.

       hostIP
           This is the IP address of the host specified in the previous parameter. This address
           must be supplied if the hostname parameter is supplied.

FILES

       smb.conf(5)
           This is usually the name of the configuration file used by smbd(8).

DIAGNOSTICS

       The program will issue a message saying whether the configuration file loaded OK or not.
       This message may be preceded by errors and warnings if the file did not load. If the file
       was loaded OK, the program then dumps all known service details to stdout.

       For certain use cases, SMB protocol requires use of cryptographic algorithms which are
       known to be weak and already broken. DES and ARCFOUR (RC4) ciphers and the SHA1 and MD5
       hash algorithms are considered weak but they are required for backward compatibility. The
       testparm utility shows whether the Samba tools will fall back to these weak crypto
       algorithms if it is not possible to use strong cryptography by default. In FIPS mode weak
       crypto cannot be enabled.
