rpcclient — tool for executing client side MS-RPC functions
rpcclient [-A authfile] [-c <command string>] [-d debuglevel] [-h] [-l logdir] [-N] [-s <smb config file>] [-U username[%password]] [-W workgroup] [-N] [-I destinationIP] {server}
This tool is part of the samba(7) suite.
rpcclient is a utility initially developed
to test MS-RPC functionality in Samba itself. It has undergone
several stages of development and stability. Many system administrators
have now written scripts around it to manage Windows NT clients from
their UNIX workstation.
NetBIOS name of Server to which to connect. The server can be any SMB/CIFS server. The name is resolved using the name resolve order line from smb.conf(5).
execute semicolon separated commands (listed below))
IP address is the address of the server to connect to.
It should be specified in standard "a.b.c.d" notation.
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 name resolve order
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.
There is no default for this parameter. If not supplied, it will be determined automatically by the client as described above.
level is an integer
from 0 to 10. The default value if this parameter is
not specified is 0.
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.
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.
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 Directory environment.
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.
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 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. 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.
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 communicate with.
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).
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
options.

Execute an AddPrinterDriver() RPC to install the printer driver
information on the server. Note that the driver files should
already exist in the directory returned by
getdriverdir. Possible values for
arch are the same as those for
the getdriverdir command.
The config parameter is defined as
follows:
Long Printer Name:\ Driver File Name:\ Data File Name:\ Config File Name:\ Help File Name:\ Language Monitor Name:\ Default Data Type:\ Comma Separated list of Files
Any empty fields should be enter as the string "NULL".
Samba does not need to support the concept of Print Monitors since these only apply to local printers whose driver can make use of a bi-directional link for communication. This field should be "NULL". On a remote NT print server, the Print Monitor for a driver must already be installed prior to adding the driver or else the RPC will fail.
The version parameter lets you
specify the printer driver version number. If omitted, the
default driver version for the specified architecture will
be used. This option can be used to upload Windows 2000
(version 3) printer drivers.
Add a printer on the remote server. This printer
will be automatically shared. Be aware that the printer driver
must already be installed on the server (see adddriver)
and the portmust be a valid port name (see
enumports.
Delete the specified printer driver for all architectures. This does not delete the actual driver files from the server, only the entry from the server's list of drivers.
Delete the specified printer driver including driver files. You can limit this action to a specific architecture and a specific version. If no architecure is given, all driver files of that driver will be deleted.
Enumerate all printer setting data stored on the server. On Windows NT clients, these values are stored in the registry, while Samba servers store them in the printers TDB. This command corresponds to the MS Platform SDK GetPrinterData() function (* This command is currently unimplemented).
Enumerate printer data for a key
List the jobs and status of a given printer. This command corresponds to the MS Platform SDK EnumJobs() function
Enumerate printer keys
Executes an EnumPorts() call using the specified info level. Currently only info levels 1 and 2 are supported.
Execute an EnumPrinterDrivers() call. This lists the various installed printer drivers for all architectures. Refer to the MS Platform SDK documentation for more details of the various flags and calling options. Currently supported info levels are 1, 2, and 3.
Execute an EnumPrinters() call. This lists the various installed and share printers. Refer to the MS Platform SDK documentation for more details of the various flags and calling options. Currently supported info levels are 1, 2 and 5.
Retrieve the data for a given printer setting. See
the enumdata command for more information.
This command corresponds to the GetPrinterData() MS Platform
SDK function.
Get printer driver data with keyname
Retrieve the printer driver information (such as driver file, config file, dependent files, etc...) for the given printer. This command corresponds to the GetPrinterDriver() MS Platform SDK function. Currently info level 1, 2, and 3 are supported.
Execute a GetPrinterDriverDirectory()
RPC to retrieve the SMB share name and subdirectory for
storing printer driver files for a given architecture. Possible
values for arch are "Windows 4.0"
(for Windows 95/98), "Windows NT x86", "Windows NT PowerPC", "Windows
Alpha_AXP", and "Windows NT R4000".
Retrieve the current printer information. This command corresponds to the GetPrinter() MS Platform SDK function.
Get print processor directory
Execute an OpenPrinterEx() and ClosePrinter() RPC against a given printer.
Execute a SetPrinter() command to update the printer driver associated with an installed printer. The printer driver must already be correctly installed on the print server.
See also the enumprinters and
enumdrivers commands for obtaining a list of
of installed printers and drivers.

Rffpcnex test
rpcclient is designed as a developer testing tool
and may not be robust in certain areas (such as command line parsing).
It has been known to generate a core dump upon failures when invalid
parameters where passed to the interpreter.
From Luke Leighton's original rpcclient man page:
WARNING! The MSRPC over SMB code has been developed from examining Network traces. No documentation is available from the original creators (Microsoft) on how MSRPC over SMB works, or how the individual MSRPC services work. Microsoft's implementation of these services has been demonstrated (and reported) to be... a bit flaky in places.
The development of Samba's implementation is also a bit rough, and as more of the services are understood, it can even result in versions of smbd(8) and rpcclient(1) that are incompatible for some commands or services. Additionally, the developers are sending reports to Microsoft, and problems found or reported to Microsoft are fixed in Service Packs, which may result in incompatibilities.
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 original rpcclient man page was written by Matthew Geddes, Luke Kenneth Casson Leighton, and rewritten by Gerald Carter. The conversion to DocBook for Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
