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]
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
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(4).
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
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
Prints the program version number.
-s <configuration file>
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.
-n <primary NetBIOS name>
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
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

adddriver <arch> <config> [<version>]
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.
addprinter <printername> <sharename> <drivername> <port>
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.
deldriverex <driver> [architecture] [version]
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
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.

information. This command corresponds to the GetPrinterData() MS Platform SDK
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
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

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(1M) 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.
This man page is correct for version 3.0 of the Samba suite.
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

Samba Web Administration Tool is a service providing access to browser-based Samba
administration interface and on-line documentation. The service runs on software
loopback network interface on port 901/tcp, i.e. opening "http://localhost:901/" in
browser will access the SWAT service on local machine.
Please note: SWAT uses HTTP Basic Authentication scheme where user name and passwords are
sent over the network in clear text. In the SWAT case the user name is root. Transferring
such sensitive data is advisable only on the software loopback network interface or over
