19.11. Samba Distribution Programs
findsmb <subnet_broadcast_address>
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:
findsmb

net <protocol> <function> <misc_options> <target_options>
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:
net -l share -S wakko
Password:
Enumerating shared resources (exports) on remote server:
Share name Type Description

data Disk Wakko data share
tmp Disk Wakko tmp share

ADMIN$ IPC IPC Service (Samba Server)
The following example displays a list of Samba users for a host named wakko:
net -l user -S wakko

nmblookup <options> <netbios_name>
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
querying trek on 10.1.59.255
10.1.56.45 trek<00>
pdbedit <options>
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:
pdbedit -a kristin

rpcclient <server> <options>
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.
smbcacls <//server/share> <filename> <options>
The smbcacls program modifies Windows ACLs on files and directories shared by the Samba server.
smbclient <//server/share> <password> <options>
The smbclient program is a versatile UNIX client which provides functionality similar to ftp.
smbcontrol -i <options>
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.
smbpasswd <options> <username> <password>
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.
smbspool <job> <user> <title> <copies> <options> <filename>
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.
smbstatus <options>
The smbstatus program displays the status of current connections to a Samba server.
smbtar <options>
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.
testparm <options> <filename> <hostname IP_address>
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:
testparm
Load smb config files from /etc/samba/smb.conf
Processing section "[homes]"
Processing section "[printers]"
Processing section "[tmp]"
Processing section "[html]"
Loaded services file OK.
Server role: ROLE_STANDALONE
