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

Samba-tool consists of many sub-commands, each of which have their own set of options. The options listed in this section are common across several sub-commands.

-h|--help
    Show a 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 /opt/local/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.

    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 /opt/local/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 should use DNS names instead of IP addresses when connecting to a service. By default Samba client tools will try to use the default Kerberos credential cache (ccache). In case the ccache does not exist or -U|--user option was specified, clients will ask to enter a password and will obtain a Kerberos ticket (kinit) for you. If you want to use an alternative Kerberos credentical cache, use the --use-krb5-ccache option.

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

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

    This will enforce --use-kerberos=required.

-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!

-H URL, --URL=URL
    LDB URL for database or target server.

    The URL can either be a plain file path, or use one of the schemes listed here. If a plain path is used, it is treated as if 'tdb://' was used.

    tdb://PATH
        PATH is the location of a TDB database.

    mdb://PATH
        PATH is the location of an LMDB database.

    ldb://PATH
        PATH is the location of an LDB database, in either LMDB or TDB format. The formats will be tried one after another until one succeeds or all fail. It is safe to use this if you don't know the format of the file.

    ldap://HOSTNAME, ldaps://HOSTNAME
        The LDB backend is the named ldap server. ldaps:// wraps the connection in TLS.

    ldapi://SOCKET
        The backend server is a local ldap server using a unix domain socket.

--color=always|never|auto
    use colour if available (default: auto)

--ipaddress=IPADDRESS
    IP address of the server

-s FILE, --configfile=FILE
    Use this smb.conf configuration file.

--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.

-V, --version
    Display the version number and exit.

-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 /opt/local/etc/samba/smb.conf file.

--debug-stdout
    This will redirect debug output to STDOUT. By default all clients are logging to STDERR.

This can populate, describe or delete msDS-KeyCredentialLink attributes.

  computer keytrust add computername public-key-or-certificate[options]

Add a key-credential-link, which is a linked attribute that holds a public key in a binary field.

The second argument is a filename that should refer to a 2048 bit RSA key (or a certificate containing that key) in PEM or DER format. By default the encoding format will be detected automatically, but you can attempt to override this with --encoding option. Other types of public key are not supported, though the --force option can be used to add a non-2048 bit key.

--link-target=DN
    link to this DN (default: the computer's DN)

--encoding=ENCODING

  computer keytrust delete computername [options]

Delete a key-credential-link.

The link to be deleted can be selected in a number of ways. --all will delete all key credential links for the computer (often there will only be one). The --link-target option selects a key credential link based on the DN targeted by the link. The --fingerprint option selects a link to delete based on the key fingerprint. This is the SHA256 of the DER-encoded key material, expressed as hex-pairs separated by colons. See computer keytrust view to get a list of links and their fingerprints.

If more than one of --link-target, --fingerprint, and --all are used, links matched by any of them will be deleted.

  user keytrust

Manage Key Credential Links for a user.

This can populate, describe or delete msDS-KeyCredentialLink attributes.

  user keytrust add username public-key-or-certificate[options]

Add a key-credential-link, which is a linked attribute that holds a public key in a binary field.

The second argument is a filename that should refer to a 2048 bit RSA key (or a certificate containing that key) in PEM or DER format. By default the encoding format will be detected automatically, but you can attempt to override this with --encoding option. Other types of public key are not supported, though the --force option can be used to add a non-2048 bit key.

--link-target=DN
    link to this DN (default: the user's DN)

--encoding=ENCODING
    Key format, either pem, der, or auto. The default is auto, which is likely to detect the correct format in all circumstances.

--force
    proceed with operations that seems ill-fated

  user keytrust delete username [options]

Delete a key-credential-link.

The link to be deleted can be selected in a number of ways. --all will delete all key credential links for the user (often there will only be one). The --link-target option selects a key credential link based on the DN targeted by the link. The --fingerprint option selects a link to delete based on the key fingerprint. This is the SHA256 of the DER-encoded key material, expressed as hex-pairs separated by colons. See user keytrust view to get a list of links and their fingerprints.

If more than one of --link-target, --fingerprint, and --all are used, links matched by any of them will be deleted.

The --dry-run option will prevent links from being deleted, and instead indicate what would happen if it was omitted.

--link-target=DN
    Delete this key credential link (a DN)

--fingerprint=HH:HH:..
    Delete the key credential link with this key fingerprint

--all
    Delete all key credential links

-n, --dry-run
    Do nothing but print what would happen

  user keytrust view username [options]

View a user's key credential links. This can be used to find a link's fingerprint and target DN for . The --verbose includes more, probably useless, information.

-h, --help
    show this help message and exit

-v, --verbose

  vampire [options] domain

Join and synchronise a remote AD domain to the local server. Please note that samba-tool vampire is deprecated, please use samba-tool domain join instead.

  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.
