17 --realm=REALM
19 Set the realm name
20 --simple-bind-dn=DN
22 DN to use for a simple bind
23 --password=PASSWORD
25 Password
26 -U USERNAME|--username=USERNAME

37 Use Kerberos
38 --ipaddress=IPADDRESS
40 IP address of the server
41 -d|--debuglevel=level
43 level is an integer from 0 to 10. The default value if this
44 parameter is not specified is 1.
45 The higher this value, the more detail will be logged to the log
47 files about the activities of the server. At level 0, only critical
48 errors and serious warnings will be logged. Level 1 is a reasonable
49 level for day-to-day running - it generates a small amount of
50 information about operations carried out.
51 Levels above 1 will generate considerable amounts of log data, and
53 should only be used when investigating a problem. Levels above 3
54 are designed for use only by developers and generate HUGE amounts
55 of log data, most of which is extremely cryptic.
56 Note that specifying this parameter here will override the log
58 level parameter in the smb.conf file.
59 -V|--version
61 Prints the program version number.
62 -s|--configfile=<configuration file>
64 The file specified contains the configuration details required by
65 the server. The information in this file includes server-specific
66 information such as what printcap file to use, as well as
67 descriptions of all the services that the server is to provide. See
68 smb.conf for more information. The default configuration file name
69 is determined at compile time.
70 -l|--log-basename=logdirectory
72 Base directory name for log/debug files. The extension ".progname"
73 will be appended (e.g. log.smbclient, log.smbd, etc...). The log
74 file is never removed by the client.
75 --option=<name>=<value>
77 Set the smb.conf(5) option "<name>" to value "<value>" from the
78 command line. This overrides compiled-in defaults and options read
79 from the configuration file.

754 visualize [options] subcommand
756 Produce graphical representations of Samba network state. To work out
757 what is happening in a replication graph, it is sometimes helpful to
758 use visualisations.
759 There are two subcommands, two graphical modes, and (roughly) two modes
761 of operation with respect to the location of authority.
762 MODES OF OPERATION
764 samba-tool visualize ntdsconn
765 Looks at NTDS connections.
766 samba-tool visualize reps
768 Looks at repsTo and repsFrom objects.
769 samba-tool visualize uptodateness
771 Looks at replication lag as shown by the uptodateness vectors.
772 GRAPHICAL MODES
774 --distance
775 Distances between DCs are shown in a matrix in the terminal.
776 --dot
778 Generate Graphviz dot output (for ntdsconn and reps modes). When
779 viewed using dot or xdot, this shows the network as a graph with
780 DCs as vertices and connections edges. Certain types of degenerate
781 edges are shown in different colours or line-styles.
782 --xdot
784 Generate Graphviz dot output as with [--dot] and attempt to view it
785 immediately using /usr/bin/xdot.
786 -r
788 Normally, samba-tool talks to one database; with the [-r] option
789 attempts are made to contact all the DCs known to the first
790 database. This is necessary for samba-tool visualize uptodateness
791 and for samba-tool visualize reps because the repsFrom/To objects
792 are not replicated, and it can reveal replication issues in other
793 modes.
794 help
