Print a summary of command line options.
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.
Display brief usage message.
Prints the program version number.
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.
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.
Set the smb.conf(5) option "" to value "" from the
command line. This overrides compiled-in defaults and options read
from the configuration file.
This option allows you to override the NetBIOS name that Samba uses
for itself. This is identical to setting the netbios name parameter
in the smb.conf file. However, a command line setting will take
precedence over settings in smb.conf.
This specifies a NetBIOS scope that nmblookup will use to
communicate with when generating NetBIOS names. For details on the
use of NetBIOS scopes, see rfc1001.txt and rfc1002.txt. NetBIOS
scopes are very rarely used, only set this parameter if you are the
system administrator in charge of all the NetBIOS systems you
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
-O|--socket-options socket options
TCP socket options to set on the client socket. See the socket
options parameter in the smb.conf manual page for the list of valid
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
ingnored and no password will be used.
Try to authenticate with kerberos. Only useful in an Active
Try to use the credentials cached by winbind.
This option allows you to specify a file from which to read the
username and password used in the connection. The format of the

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, then the
LOGNAME variable and if either exists, the string is uppercased. If
these environmental variables are not found, the username GUEST is
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. Also, on many
systems the command line of a running process may be seen via the
ps command. To be safe always allow rpcclient to prompt for a
password and type it in directly.
Set the client signing state.
Use stored machine account password.
This command line parameter requires the remote server support the
UNIX extensions or that the SMB3 protocol has been selected.
Requests that the connection be encrypted. Negotiates SMB
encryption using either SMB3 or POSIX extensions via GSSAPI. Uses
the given credentials for the encryption negotiation (either
kerberos or NTLMv1/v2 if given domain/username/password triple.
Fails the connection if encryption cannot be negotiated.
The supplied password is the NT hash.
The original Samba software and related utilities were created by
Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
The samba-regedit man page was written by Karolin Seeger.
