testparm – check an smb.conf configuration file for internal


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.


Without this option, testparm will prompt for a carriage return
after printing the service names and before dumping the service

Prints the program version number.

Set the smb.conf(5) option “” to value “” from the
command line. This overrides compiled-in defaults and options read
from the configuration file.

Print a summary of command line options.

Display brief usage message.

level is an integer from 0 to 10. The default value if this
parameter is not specified is 1.

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 smb.conf file.

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

–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 the parameters, type, possible values.

Skip the global checks.

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

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.

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

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

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.

This man page is correct for version 3 of the Samba suite.


smb.conf(5), smbd(8)


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.

The original Samba man pages were written by Karl Auer. The man page
sources were converted to YODL format (another excellent piece of Open
Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and
updated for the Samba 2.0 release by Jeremy Allison. The conversion to
DocBook for Samba 2.2 was done by Gerald Carter. The conversion to
DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
