.SH "DESCRIPTION"
.PP
This tool is part of the
\fBsamba\fR(7)
suite\&.
.PP
smbtree
is a smb browser program in text mode\&. It is similar to the "Network Neighborhood" found on Windows computers\&. It prints a tree with all the known domains, the servers in those domains and the shares on the servers\&.
.SH "OPTIONS"
.PP
\-D|\-\-domains
.RS 4
Only print a list of all the domains known on broadcast or by the master browser
.RE
.PP
\-S|\-\-servers
.RS 4
Only print a list of all the domains and servers responding on broadcast or known by the master browser\&.
.RE
.PP
\-?|\-\-help
.RS 4
Print a summary of command line options\&.
.RE
.PP
\-\-usage
.RS 4
Display brief usage message\&.
.RE
.PP
\-d|\-\-debuglevel=DEBUGLEVEL
.RS 4
\fIlevel\fR
is an integer from 0 to 10\&. The default value if this parameter is not specified is 1 for client applications\&.
.sp
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\&.
.sp
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\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBlog level\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&.
.RE
.PP
\-\-debug\-stdout
.RS 4
This will redirect debug output to STDOUT\&. By default all clients are logging to STDERR\&.
.RE
.PP
\-\-configfile=<configuration file>
.RS 4
The file specified contains the configuration details required by the client\&. The information in this file can be general for client and server or only provide client specific like options such as
\m[blue]\fBclient smb encrypt\fR\m[]\&. See
/etc/samba/smb\&.conf
for more information\&. The default configuration file name is determined at compile time\&.
.RE
.PP
\-\-option=<name>=<value>
.RS 4
Set the
\fBsmb.conf\fR(5)
option "<name>" to value "<value>" from the command line\&. This overrides compiled\-in defaults and options read from the configuration file\&. If a name or a value includes a space, wrap whole \-\-option=name=value into quotes\&.
.RE
.PP
\-l|\-\-log\-basename=logdirectory
.RS 4
Base directory name for log/debug files\&. The extension
\fB"\&.progname"\fR
will be appended (e\&.g\&. log\&.smbclient, log\&.smbd, etc\&.\&.\&.)\&. The log file is never removed by the client\&.
.RE
.PP
\-\-leak\-report
.RS 4
Enable talloc leak reporting on exit\&.
.RE
.PP
\-\-leak\-report\-full
.RS 4
Enable full talloc leak reporting on exit\&.
.RE
.PP
\-V|\-\-version
.RS 4
Prints the program version number\&.
.RE
.PP
\-U|\-\-user=[DOMAIN\e]USERNAME[%PASSWORD]
.RS 4
Sets the SMB username or username and password\&.
.sp
If %PASSWORD is not specified, the user will be prompted\&. The client will first check the
\fBUSER\fR
environment variable (which is also permitted to also contain the password separated by a %), then the
\fBLOGNAME\fR
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\&.
.sp
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
\fI\-A\fR
for more details\&.
.sp
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\&.
.sp
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\&.
.RE
.PP
\-N|\-\-no\-pass
.RS 4
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\&.
.sp
Unless a password is specified on the command line or this parameter is specified, the client will request a password\&.
.sp
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\&.
.RE
.PP
\-\-password
.RS 4
Specify the password on the commandline\&.
.sp
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\&.
.sp
If \-\-password is not specified, the tool will check the
\fBPASSWD\fR
environment variable, followed by
\fBPASSWD_FD\fR
which is expected to contain an open file descriptor (FD) number\&.
.sp
Finally it will check
\fBPASSWD_FILE\fR
(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!
.sp
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\&.
.RE
.PP
\-\-pw\-nt\-hash
.RS 4
The supplied password is the NT hash\&.
.RE
.PP
\-A|\-\-authentication\-file=filename
.RS 4
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:
.sp
.if n \{\
.RS 4
.\}
.nf
				username = <value>
				password = <value>
				domain   = <value>
			
.fi
.if n \{\
.RE
.\}
.sp
Make certain that the permissions on the file restrict access from unwanted users!
.RE
.PP
\-P|\-\-machine\-pass
.RS 4
Use stored machine account password\&.
.RE
.PP
\-\-simple\-bind\-dn=DN
.RS 4
DN to use for a simple bind\&.
.RE
.PP
\-\-use\-kerberos=desired|required|off
.RS 4
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\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBclient use kerberos\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&.
.RE
.PP
\-\-use\-krb5\-ccache=CCACHE
.RS 4
Specifies the credential cache location for Kerberos authentication\&.
.sp
This will set \-\-use\-kerberos=required too\&.
.RE
.PP
\-\-use\-winbind\-ccache
.RS 4
Try to use the credential cache by winbind\&.
.RE
.PP
\-\-client\-protection=sign|encrypt|off
.RS 4
Sets the connection protection the client tool should use\&.
.sp
Note that specifying this parameter here will override the
\m[blue]\fBclient protection\fR\m[]
parameter in the
/etc/samba/smb\&.conf
file\&.
.sp
In case you need more fine grained control you can use:
\-\-option=clientsmbencrypt=OPTION,
\-\-option=clientipcsigning=OPTION,
\-\-option=clientsigning=OPTION\&.
