SAMBA-TOOL(8) System Administration tools SAMBA-TOOL(8)

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.
