NAME
samba-tool - Main Samba administration tool.
SYNOPSIS
samba-tool [-h] [-W myworkgroup] [-U user] [-d debuglevel] [--v]
DESCRIPTION
This tool is part of the samba(7) suite.
OPTIONS
-h|--help
Show this help message and exit
--realm=REALM
Set the realm name
--simple-bind-dn=DN
DN to use for a simple bind
--password=PASSWORD
Password
-U USERNAME|--username=USERNAME
Username
-W WORKGROUP|--workgroup=WORKGROUP
Workgroup
-N|--no-pass
Don't ask for a password
-k KERBEROS|--kerberos=KERBEROS
Use Kerberos
--ipaddress=IPADDRESS
IP address of the server
-d|--debuglevel=level
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.
-V|--version
Prints the program version number.
-s|--configfile=<configuration file>
The file specified contains the configuration details required by
the server. The information in this file includes server-specific
information such as what printcap file to use, as well as
descriptions of all the services that the server is to provide. See
smb.conf for more information. The default configuration file name
is determined at compile time.
-l|--log-basename=logdirectory
Base directory name for log/debug files. The extension ".progname"
will be appended (e.g. log.smbclient, log.smbd, etc...). The log
file is never removed by the client.
--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.

visualize [options] subcommand
Produce graphical representations of Samba network state. To work out
what is happening in a replication graph, it is sometimes helpful to
use visualisations.
There are two subcommands, two graphical modes, and (roughly) two modes
of operation with respect to the location of authority.
MODES OF OPERATION
samba-tool visualize ntdsconn
Looks at NTDS connections.
samba-tool visualize reps
Looks at repsTo and repsFrom objects.
samba-tool visualize uptodateness
Looks at replication lag as shown by the uptodateness vectors.
GRAPHICAL MODES
--distance
Distances between DCs are shown in a matrix in the terminal.
--dot
Generate Graphviz dot output (for ntdsconn and reps modes). When
viewed using dot or xdot, this shows the network as a graph with
DCs as vertices and connections edges. Certain types of degenerate
edges are shown in different colours or line-styles.
--xdot
Generate Graphviz dot output as with [--dot] and attempt to view it
immediately using /usr/bin/xdot.
-r
Normally, samba-tool talks to one database; with the [-r] option
attempts are made to contact all the DCs known to the first
database. This is necessary for samba-tool visualize uptodateness
and for samba-tool visualize reps because the repsFrom/To objects
are not replicated, and it can reveal replication issues in other
modes.
help
Gives usage information.
