22.11. Samba Distribution Programs
The
findsmb
program is a Perl script which reports information about SMB-aware systems on a specific subnet. If no subnet is specified the local subnet is used. Items displayed include IP address, NetBIOS name, workgroup or domain name, operating system, and version.
The following example shows the output of executing
findsmb
as any valid user on a system:
The
net
utility is similar to the net
utility used for Windows and MS-DOS. The first argument is used to specify the protocol to use when executing a command. The <protocol>
option can be ads
, rap
, or rpc
for specifying the type of server connection. Active Directory uses ads
, Win9x/NT3 uses rap
, and Windows NT4/2000/2003 uses rpc
. If the protocol is omitted, net
automatically tries to determine it.
The following example displays a list the available shares for a host named
wakko
:
The following example displays a list of Samba users for a host named

The
nmblookup
program resolves NetBIOS names into IP addresses. The program broadcasts its query on the local subnet until the target machine replies.
Here is an example:
nmblookup trek
~]# nmblookup trek
querying trek on 10.1.59.255
10.1.56.45 trek<00>
The
pdbedit
program manages accounts located in the SAM database. All backends are supported including smbpasswd
, LDAP, NIS+, and the tdb
database library.
The following are examples of adding, deleting, and listing users:
The
rpcclient
program issues administrative commands using Microsoft RPCs, which provide access to the Windows administration graphical user interfaces (GUIs) for systems management. This is most often used by advanced users that understand the full complexity of Microsoft RPCs.
The
smbcacls
program modifies Windows ACLs on files and directories shared by the Samba server.
The
smbclient
program is a versatile UNIX client which provides functionality similar to ftp
.
smbcontrol <options> <destination> <messagetype> <parameters>
The
smbcontrol
program sends control messages to running smbd
or nmbd
daemons. Executing smbcontrol -i
runs commands interactively until a blank line or a 'q' is entered.
The
smbpasswd
program manages encrypted passwords. This program can be run by a superuser to change any user's password as well as by an ordinary user to change their own Samba password.
The
smbspool
program is a CUPS-compatible printing interface to Samba. Although designed for use with CUPS printers, smbspool
can work with non-CUPS printers as well.
The
smbstatus
program displays the status of current connections to a Samba server.
The
smbtar
program performs backup and restores of Windows-based share files and directories to a local tape archive. Though similar to the tar
command, the two are not compatible.
The
testparm
program checks the syntax of the smb.conf
file. If your smb.conf
file is in the default location (/etc/samba/smb.conf
) you do not need to specify the location. Specifying the hostname and IP address to the testparm
program verifies that the hosts.allow
and host.deny
files are configured correctly. The testparm
program also displays a summary of your smb.conf
file and the server's role (stand-alone, domain, etc.) after testing. This is convenient when debugging as it excludes comments and concisely presents information for experienced administrators to read.
For example:
The
wbinfo
program displays information from the winbindd
daemon. The winbindd
daemon must be running for wbinfo
to work.
