testparm 1 Samba User Commands &doc.version; testparm check an smb.conf configuration file for internal correctness testparm -s|--suppress-prompt --help -v|--verbose config filename hostname hostIP 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. -s|--suppress-prompt Without this option, testparm will prompt for a carriage return after printing the service names and before dumping the service definitions. &stdarg.version; &stdarg.option; &popt.autohelp; &stdarg.client.debug; -v|--verbose If this option is specified, testparm will also output all options that were not used in smb.conf5 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. configfilename This is the name of the configuration file to check. If this parameter is not present then the default smb.conf5 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.conf5 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. smb.conf5 This is usually the name of the configuration file used by smbd8 . 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. This man page is part of version &doc.version; of the Samba suite. smb.conf5 , smbd8 The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.
