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

−r|−−realm=REALM

Set the realm for the domain.

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

−−simple−bind−dn=DN

DN to use for a simple bind.

−−password

Specify the password on the commandline.

Be cautious about including passwords in scripts or passing user−supplied values onto the command line. For security it is better to let the Samba client tool ask for the password if needed, or obtain the password once with kinit.

If −−password is not specified, the tool will check the PASSWD environment variable, followed by PASSWD_FD which is expected to contain an open file descriptor (FD) number.

Finally it will check PASSWD_FILE (containing a file path to be opened). The file should only contain the password. Make certain that the permissions on the file restrict access from unwanted users!

While Samba will attempt to scrub the password from the process title (as seen in ps), this is after startup and so is subject to a race.

−U|−−user=[DOMAIN\]USERNAME[%PASSWORD]

Sets the SMB username or username and password.

If %PASSWORD is not specified, the user will be prompted. The client will first check the USER environment variable (which is also permitted to also contain the password separated by a %), then the LOGNAME variable (which is not permitted to contain a password) and if either exists, the value is used. If these environmental variables are not found, the username found in a Kerberos Credentials cache may be used.

A third option is to use a credentials file which contains the plaintext of the username and password. This option is mainly provided for scripts where the admin does not wish to pass the credentials on the command line or via environment variables. If this method is used, make certain that the permissions on the file restrict access from unwanted users. See the −A for more details.

While Samba will attempt to scrub the password from the process title (as seen in ps), this is after startup and so is subject to a race.

−W|−−workgroup=WORKGROUP

Set the SMB domain of the username. This overrides the default domain which is the domain defined in smb.conf. If the domain specified is the same as the servers NetBIOS name, it causes the client to log on using the servers local SAM (as opposed to the Domain SAM).

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

−N|−−no−pass

If specified, this parameter suppresses the normal password prompt from the client to the user. This is useful when accessing a service that does not require a password.

Unless a password is specified on the command line or this parameter is specified, the client will request a password.

If a password is specified on the command line and this option is also defined the password on the command line will be silently ignored and no password will be used.

−−use−kerberos=desired|required|off

This parameter determines whether Samba client tools will try to authenticate using Kerberos. For Kerberos authentication you need to use dns names instead of IP addresses when connecting to a service.

Note that specifying this parameter here will override the client use kerberos parameter in the /etc/samba/smb.conf file.

−−use−krb5−ccache=CCACHE

Specifies the credential cache location for Kerberos authentication.

This will set −−use−kerberos=required too.

−A|−−authentication−file=filename

This option allows you to specify a file from which to read the username and password used in the connection. The format of the file is:



					username = <value>


					password = <value>


					domain = <value>

Make certain that the permissions on the file restrict access from unwanted users!

−−ipaddress=IPADDRESS

IP address of the server

−−color=always|never|auto

Indicate whether samba−tool should use ANSI colour codes in its output. If 'auto' (the default), samba−tool will use colour when its output is directed toward a terminal, unless the NO_COLOR environment variable is set and non−empty.

The values 'yes' and 'force' are accepted as synonyms for 'always'; 'no' and 'none' for 'never'; and 'tty' and 'if−tty' for 'auto'.

Note that asking for colour doesn't mean samba−tool will necessarily be very colourful. Many commands are very monochrome, particularly when successful.

−d|−−debuglevel=level

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.

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.

VERSION

This man page is complete for version 4.22.10 of the Samba suite.
