14.8. Samba Distribution Programs

14.8.1. findsmb

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
 
IP ADDR       NETBIOS NAME  WORKGROUP/OS/VERSION
------------------------------------------------------------------
10.1.59.25    VERVE         [MYGROUP] [Unix] [Samba 3.0.0-15]
10.1.59.26    STATION22     [MYGROUP] [Unix] [Samba 3.0.2-7.FC1]

10.1.57.141   JAWS         +[KWIKIMART] [Unix] [Samba 2.2.7a-security-rollup-fix]
10.1.56.159   FRED         +[MYGROUP] [Unix] [Samba 3.0.0-14.3E]

10.1.56.205   NANCYN       +[MYGROUP] [Unix] [Samba 2.2.7a-security-rollup-fix]

14.8.2. make_smbcodepage

make_smbcodepage <c|d> <codepage_number> <inputfile> <outputfile>

The make_smbcodepage program compiles a binary codepage file from a text-format definition. The reverse is also allowed by decompiling a binary codepage file to a text-format definition. This obsolete program is part of the internationalization features of previous versions of Samba which are included by default with the current version of Samba.

14.8.3. make_unicodemap

make_unicodemap <codepage_number> <inputfile> <outputfile>

The make_unicodemap program compiles binary Unicode files from text files so Samba can display non-ASCII charactersets. This obsolete program was part of the internationalization features of previous versions of Samba which are now included with the current release of Samba.

14.8.4. net

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
IPC$         IPC      IPC Service (Samba Server)
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
root password:
 
User name             Comment
-----------------------------
andriusb              Documentation
joe                   Marketing
lisa                  Sales

14.8.5. nmblookup

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>

14.8.6. pdbedit

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
new password:
retype new password:
Unix username:        kristin
NT username:
Account Flags:        [U          ]

14.8.7. rpcclient

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.

14.8.8. smbcacls

smbcacls <//server/share> <filename> <options>

The smbcacls program modifies Windows ACLs on files and directories shared by the Samba server.

14.8.9. smbclient

smbclient <//server/share> <password> <options>

The smbclient program is a versatile UNIX client which provides functionality similar to ftp.

14.8.10. smbcontrol

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.

14.8.11. smbgroupedit

smbgroupedit <options>

The smbgroupedit program maps between Linux groups and Windows groups. It also allows a Linux group to be a domain group.

14.8.12. smbmount

smbmount <//server/share> <mount_point> <-o options>

The smbmount program uses the low-level smbmnt program to mount an smbfs file system (Samba share). The mount -t smbfs <//server/share> <mount_point> <-o options> command also works.

For example:

smbmount //wakko/html /mnt/html -o username=kristin
Password: <password>
[[email protected] /]# ls -l /mnt/html
total 0
-rwxr-xr-x    1 root     root            0 Jan 29 08:09 index.html

14.8.13. smbpasswd

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.

14.8.14. smbspool

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.

14.8.15. smbstatus

smbstatus <options>

The smbstatus program displays the status of current connections to a Samba server.

14.8.16. smbtar

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.

14.8.17. testparm

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

        read only = No
        guest only = Yes

14.8.18. testprns

testprns <printername> <printcapname>

The testprns program checks if printername is valid and exists in the printcap. If the printcapname is not specified, the default specified in the Samba or printcap configuration files is used.

14.8.19. wbinfo

wbinfo <options>

The wbinfo program displays information from the winbindd daemon. The winbindd daemon must be running for wbinfo to work.
