.SH "DESCRIPTION"
.PP
This tool is part of the
\fBsamba\fR(7)
suite\&.
.PP
\FCsmbclient\F[]
is a client that can \'talk\' to an SMB/CIFS server\&. It offers an interface similar to that of the ftp program (see
\fBftp\fR(1))\&. Operations include things like getting files from the server to the local machine, putting files from the local machine to the server, retrieving directory information from the server and so on\&.
.SH "OPTIONS"
.PP
servicename
.RS 4
servicename is the name of the service you want to use on the server\&. A service name takes the form
\FC//server/service\F[]
where
\fIserver \fR
is the NetBIOS name of the SMB/CIFS server offering the desired service and
\fIservice\fR
is the name of the service offered\&. Thus to connect to the service "printer" on the SMB/CIFS server "smbserver", you would use the servicename
\FC//smbserver/printer \F[]
.sp
Note that the server name required is NOT necessarily the IP (DNS) host name of the server ! The name required is a NetBIOS server name, which may or may not be the same as the IP hostname of the machine running the server\&.
.sp
The server name is looked up according to either the
\fI\-R\fR
parameter to
\FCsmbclient\F[]
or using the name resolve order parameter in the
\fBsmb.conf\fR(5)
file, allowing an administrator to change the order and methods by which server names are looked up\&.
.RE
.PP
password
.RS 4
The password required to access the specified service on the specified server\&. If this parameter is supplied, the
\fI\-N\fR
option (suppress password prompt) is assumed\&.
.sp
There is no default password\&. If no password is supplied on the command line (either by using this parameter or adding a password to the
\fI\-U\fR
option (see below)) and the
\fI\-N\fR
option is not specified, the client will prompt for a password, even if the desired service does not require one\&. (If no password is required, simply press ENTER to provide a null password\&.)
.sp
Note: Some servers (including OS/2 and Windows for Workgroups) insist on an uppercase password\&. Lowercase or mixed case passwords may be rejected by these servers\&.
.sp
Be cautious about including passwords in scripts\&.
.RE
.PP
\-R <name resolve order>
.RS 4
This option is used by the programs in the Samba suite to determine what naming services and in what order to resolve host names to IP addresses\&. The option takes a space\-separated string of different name resolution options\&.
.sp
The options are :"lmhosts", "host", "wins" and "bcast"\&. They cause names to be resolved as follows:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBlmhosts\fR: Lookup an IP address in the Samba lmhosts file\&. If the line in lmhosts has no name type attached to the NetBIOS name (see the
\fBlmhosts\fR(5)
for details) then any name type matches for lookup\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBhost\fR: Do a standard host name to IP address resolution, using the system
\FC/etc/hosts \F[], NIS, or DNS lookups\&. This method of name resolution is operating system dependent, for instance on IRIX or Solaris this may be controlled by the
\FC/etc/nsswitch\&.conf\F[]
file)\&. Note that this method is only used if the NetBIOS name type being queried is the 0x20 (server) name type, otherwise it is ignored\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBwins\fR: Query a name with the IP address listed in the
\fIwins server\fR
parameter\&. If no WINS server has been specified this method will be ignored\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fBbcast\fR: Do a broadcast on each of the known local interfaces listed in the
\fIinterfaces\fR
parameter\&. This is the least reliable of the name resolution methods as it depends on the target host being on a locally connected subnet\&.
.sp
.RE
If this parameter is not set then the name resolve order defined in the
\fBsmb.conf\fR(5)
file parameter (name resolve order) will be used\&.
.sp
The default order is lmhosts, host, wins, bcast and without this parameter or any entry in the
\fIname resolve order \fR
parameter of the
\fBsmb.conf\fR(5)
file the name resolution methods will be attempted in this order\&.
.RE
.PP
\-M NetBIOS name
.RS 4
This options allows you to send messages, using the "WinPopup" protocol, to another computer\&. Once a connection is established you then type your message, pressing ^D (control\-D) to end\&.
.sp
If the receiving computer is running WinPopup the user will receive the message and probably a beep\&. If they are not running WinPopup the message will be lost, and no error message will occur\&.
.sp
The message is also automatically truncated if the message is over 1600 bytes, as this is the limit of the protocol\&.
.sp
One useful trick is to pipe the message through
\FCsmbclient\F[]\&. For example: smbclient \-M FRED < mymessage\&.txt will send the message in the file
\FCmymessage\&.txt\F[]
to the machine FRED\&.
.sp
You may also find the
\fI\-U\fR
and
\fI\-I\fR
options useful, as they allow you to control the FROM and TO parts of the message\&.
.sp
See the
\fImessage command\fR
parameter in the
\fBsmb.conf\fR(5)
for a description of how to handle incoming WinPopup messages in Samba\&.
.sp
\fINote\fR: Copy WinPopup into the startup group on your WfWg PCs if you want them to always be able to receive messages\&.
.RE
.PP
\-p port
.RS 4
This number is the TCP port number that will be used when making connections to the server\&. The standard (well\-known) TCP port number for an SMB/CIFS server is 139, which is the default\&.
.RE
.PP
\-g
.RS 4
This parameter provides combined with
\fI\-L\fR
easy parseable output that allows processing with utilities such as grep and cut\&.
.RE
.PP
\-P
.RS 4
Make queries to the external server using the machine account of the local server\&.
.RE
.PP
\-h|\-\-help
.RS 4
Print a summary of command line options\&.
.RE
.PP
\-I IP\-address
.RS 4
\fIIP address\fR
is the address of the server to connect to\&. It should be specified in standard "a\&.b\&.c\&.d" notation\&.
.sp
Normally the client would attempt to locate a named SMB/CIFS server by looking it up via the NetBIOS name resolution mechanism described above in the
\fIname resolve order\fR
parameter above\&. Using this parameter will force the client to assume that the server is on the machine with the specified IP address and the NetBIOS name component of the resource being connected to will be ignored\&.
.sp
There is no default for this parameter\&. If not supplied, it will be determined automatically by the client as described above\&.
.RE
.PP
\-E
.RS 4
This parameter causes the client to write messages to the standard error stream (stderr) rather than to the standard output stream\&.
.sp
By default, the client writes messages to standard output \- typically the user\'s tty\&.
.RE
.PP
\-L
.RS 4
This option allows you to look at what services are available on a server\&. You use it as
\FCsmbclient \-L host\F[]
and a list should appear\&. The
\fI\-I \fR
option may be useful if your NetBIOS names don\'t match your TCP/IP DNS host names or if you are trying to reach a host on another network\&.
.RE
.PP
\-t terminal code
.RS 4
This option tells
\FCsmbclient\F[]
how to interpret filenames coming from the remote server\&. Usually Asian language multibyte UNIX implementations use different character sets than SMB/CIFS servers (\fIEUC\fR
instead of
\fI SJIS\fR
for example)\&. Setting this parameter will let
\FCsmbclient\F[]
convert between the UNIX filenames and the SMB filenames correctly\&. This option has not been seriously tested and may have some problems\&.
.sp
The terminal codes include CWsjis, CWeuc, CWjis7, CWjis8, CWjunet, CWhex, CWcap\&. This is not a complete list, check the Samba source code for the complete list\&.
.RE
.PP
\-b buffersize
.RS 4
This option changes the transmit/send buffer size when getting or putting a file from/to the server\&. The default is 65520 bytes\&. Setting this value smaller (to 1200 bytes) has been observed to speed up file transfers to and from a Win9x server\&.
.RE
.PP
\-e
.RS 4
This command line parameter requires the remote server support the UNIX extensions\&. Request that the connection be encrypted\&. This is new for Samba 3\&.2 and will only work with Samba 3\&.2 or above servers\&. Negotiates SMB encryption using GSSAPI\&. Uses the given credentials for the encryption negotiaion (either kerberos or NTLMv1/v2 if given domain/username/password triple\&. Fails the connection if encryption cannot be negotiated\&.
.RE
.PP
\-d|\-\-debuglevel=level
.RS 4
\fIlevel\fR
is an integer from 0 to 10\&. The default value if this parameter is not specified is 1\&.
.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]\fB\%smb.conf.5.html#\fR\m[]
parameter in the
\FCsmb\&.conf\F[]
file\&.
.RE
.PP
\-V|\-\-version
.RS 4
Prints the program version number\&.
.RE
.PP
\-s|\-\-configfile <configuration file>
.RS 4
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
\FCsmb\&.conf\F[]
for more information\&. The default configuration file name is determined at compile time\&.
.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
\-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 ingnored and no password will be used\&.
.RE
.PP
\-k|\-\-kerberos
.RS 4
Try to authenticate with kerberos\&. Only useful in an Active Directory environment\&.
.RE
.PP
\-C|\-\-use\-ccache
.RS 4
Try to use the credentials cached by winbind\&.
