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
           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
           seperated 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.

           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.

           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
           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 connnecting to a service.

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

       --use-krb5-ccache=CCACHE
           Specifies the credential cache location for Kerberos authentication.

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

       --ipaddress=IPADDRESS
           IP address of the server

       -d|--debuglevel=DEBUGLEVEL
           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
           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.
