DESCRIPTION
This tool is part of the samba(7) suite.
The Samba net utility is meant to work just like the net utility available for windows and
DOS. The first argument should be used to specify the protocol to use when executing a
certain command. ADS is used for ActiveDirectory, RAP is using for old (Win9x/NT3) clients
and RPC can be used for NT4 and Windows 2000. If this argument is omitted, net will try to
determine it automatically. Not all commands are available on all protocols.

-d|--debuglevel=DEBUGLEVEL
level is an integer from 0 to 10. The default value if this parameter is not specified
is 1 for client applications.
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
/etc/samba/smb.conf file.
--debug-stdout
This will redirect debug output to STDOUT. By default all clients are logging to
STDERR.
--configfile=<configuration file>
The file specified contains the configuration details required by the client. The
information in this file can be general for client and server or only provide client
specific like options such as client smb encrypt. See /etc/samba/smb.conf for more
information. The default configuration file name is determined at compile time.
--option=<name>=<value>
Set the smb.conf(5) option "<name>" to value "<value>" from the command line. This
overrides compiled-in defaults and options read from the configuration file. If a name
or a value includes a space, wrap whole --option=name=value into quotes.
-l|--log-basename=logdirectory
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.
--leak-report
Enable talloc leak reporting on exit.
--leak-report-full
Enable full talloc leak reporting on exit.
-V|--version
Prints the program version number.
-R|--name-resolve=NAME-RESOLVE-ORDER
This option is used to determine what naming services and in what order to resolve
host names to IP addresses. The option takes a space-separated string of different
name resolution options. The best ist to wrap the whole
--name-resolve=NAME-RESOLVE-ORDER into quotes.
The options are: "lmhosts", "host", "wins" and "bcast". They cause names to be
resolved as follows:
• lmhosts: Lookup an IP address in the Samba lmhosts file. If the line in
lmhosts has no name type attached to the NetBIOS name (see the lmhosts(5)
for details) then any name type matches for lookup.
• host: Do a standard host name to IP address resolution, using the system
/etc/hosts, NIS, or DNS lookups. This method of name resolution is
operating system dependent, for instance on IRIX or Solaris this may be
controlled by the /etc/nsswitch.conf file). Note that this method is only
used if the NetBIOS name type being queried is the 0x20 (server) name type,
otherwise it is ignored.
• wins: Query a name with the IP address listed in the wins server parameter.
If no WINS server has been specified this method will be ignored.
• bcast: Do a broadcast on each of the known local interfaces listed in the
interfaces parameter. This is the least reliable of the name resolution
methods as it depends on the target host being on a locally connected
subnet.
If this parameter is not set then the name resolve order defined in the
/etc/samba/smb.conf file parameter (name resolve order) will be used.
The default order is lmhosts, host, wins, bcast. Without this parameter or any entry
in the name resolve order parameter of the /etc/samba/smb.conf file, the name
resolution methods will be attempted in this order.
-O|--socket-options=SOCKETOPTIONS
TCP socket options to set on the client socket. See the socket options parameter in
the /etc/samba/smb.conf manual page for the list of valid options.
-m|--max-protocol=MAXPROTOCOL
The value of the parameter (a string) is the highest protocol level that will be
supported by the client.
Note that specifying this parameter here will override the client max protocol
parameter in the /etc/samba/smb.conf file.
-n|--netbiosname=NETBIOSNAME
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 /etc/samba/smb.conf file.
However, a command line setting will take precedence over settings in
/etc/samba/smb.conf.
--netbios-scope=SCOPE
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.
-W|--workgroup=WORKGROUP
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).
Note that specifying this parameter here will override the workgroup parameter in the
/etc/samba/smb.conf file.
-r|--realm=REALM
Set the realm for the domain.
Note that specifying this parameter here will override the realm parameter in the
/etc/samba/smb.conf file.
-U|--user=[DOMAIN\]USERNAME[%PASSWORD]
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 (which is also permitted to also contain the password
separated by a %), then the LOGNAME variable (which is not permitted to contain a
password) and if either exists, the value is used. If these environmental variables
are not found, the username found in a Kerberos Credentials cache may be 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 or passing user-supplied values onto
the command line. For security it is better to let the Samba client tool ask for the
password if needed, or obtain the password once with kinit.
While Samba will attempt to scrub the password from the process title (as seen in ps),
this is after startup and so is subject to a race.
-N|--no-pass
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 ignored and no password will be used.
--password
Specify the password on the commandline.
Be cautious about including passwords in scripts or passing user-supplied values onto
the command line. For security it is better to let the Samba client tool ask for the
password if needed, or obtain the password once with kinit.
If --password is not specified, the tool will check the PASSWD environment variable,
followed by PASSWD_FD which is expected to contain an open file descriptor (FD)
number.
Finally it will check PASSWD_FILE (containing a file path to be opened). The file
should only contain the password. Make certain that the permissions on the file
restrict access from unwanted users!
While Samba will attempt to scrub the password from the process title (as seen in ps),
this is after startup and so is subject to a race.
--pw-nt-hash
The supplied password is the NT hash.
-A|--authentication-file=filename
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!
-P|--machine-pass
Use stored machine account password.
--simple-bind-dn=DN
DN to use for a simple bind.
--use-kerberos=desired|required|off
This parameter determines whether Samba client tools will try to authenticate using
Kerberos. For Kerberos authentication you need to use dns names instead of IP
addresses when connecting to a service.
Note that specifying this parameter here will override the client use kerberos
parameter in the /etc/samba/smb.conf file.
--use-krb5-ccache=CCACHE
Specifies the credential cache location for Kerberos authentication.
This will set --use-kerberos=required too.
--use-winbind-ccache
Try to use the credential cache by winbind.
--client-protection=sign|encrypt|off
Sets the connection protection the client tool should use.
Note that specifying this parameter here will override the client protection parameter
in the /etc/samba/smb.conf file.
In case you need more fine grained control you can use:
--option=clientsmbencrypt=OPTION, --option=clientipcsigning=OPTION,
--option=clientsigning=OPTION.
COMMANDS
CHANGESECRETPW
This command allows the Samba machine account password to be set from an external
application to a machine account password that has already been stored in Active
Directory. DO NOT USE this command unless you know exactly what you are doing. The use of
this command requires that the force flag (-f) be used also. There will be NO command
prompt. Whatever information is piped into stdin, either by typing at the command line or
otherwise, will be stored as the literal machine password. Do NOT use this without care
and attention as it will overwrite a legitimate machine password without warning. YOU HAVE
BEEN WARNED.
TIME
The NET TIME command allows you to view the time on a remote server or synchronise the
time on the local server with the time on the remote server.
TIME
Without any options, the NET TIME command displays the time on the remote server. The
remote server must be specified with the -S option.
TIME SYSTEM
Displays the time on the remote server in a format ready for /bin/date. The remote server
must be specified with the -S option.
TIME SET
Tries to set the date and time of the local server to that on the remote server using
/bin/date. The remote server must be specified with the -S option.
TIME ZONE
Displays the timezone in hours from GMT on the remote server. The remote server must be
specified with the -S option.
[RPC|ADS] JOIN [TYPE] [--no-dns-updates] [-U username[%password]] [dnshostname=FQDN]
[createupn=UPN] [createcomputer=OU] [machinepass=PASS] [osName=string osVer=string]
[options]
Join a domain. If the account already exists on the server, and [TYPE] is MEMBER, the
machine will attempt to join automatically. (Assuming that the machine has been created in
server manager) Otherwise, a password will be prompted for, and a new account may be
created.
[TYPE] may be PDC, BDC or MEMBER to specify the type of server joining the domain.
[FQDN] (ADS only) set the dnsHostName attribute during the join. The default format is
netbiosname.dnsdomain.

RPC TRUSTDOM
RPC TRUSTDOM ADD DOMAIN
Add a interdomain trust account for DOMAIN. This is in fact a Samba account named DOMAIN$
with the account flag 'I' (interdomain trust account). This is required for incoming
trusts to work. It makes Samba be a trusted domain of the foreign (trusting) domain. Users
of the Samba domain will be made available in the foreign domain. If the command is used
against localhost it has the same effect as smbpasswd -a -i DOMAIN. Please note that both
commands expect a appropriate UNIX account.
RPC TRUSTDOM DEL DOMAIN
Remove interdomain trust account for DOMAIN. If it is used against localhost it has the
same effect as smbpasswd -x DOMAIN$.
RPC TRUSTDOM ESTABLISH DOMAIN
Establish a trust relationship to a trusted domain. Interdomain account must already be
created on the remote PDC. This is required for outgoing trusts to work. It makes Samba be
a trusting domain of a foreign (trusted) domain. Users of the foreign domain will be made
available in our domain. You'll need winbind and a working idmap config to make them
appear in your system.
RPC TRUSTDOM REVOKE DOMAIN
Abandon relationship to trusted domain
RPC TRUSTDOM LIST
List all interdomain trust relationships.
RPC TRUST
RPC TRUST CREATE
Create a trust object by calling lsaCreateTrustedDomainEx2. The can be done on a single

Creates a new keytab file if one doesn't exist with default entries. Default entries are
kerberos principals created from the machinename of the client, the UPN (if it exists) and
any Windows SPN(s) associated with the computer AD account for the client. If a keytab
file already exists then only missing kerberos principals from the default entries are
added. No changes are made to the computer AD account.
ADS KEYTAB ADD (principal | machine | serviceclass | windows SPN
Adds a new keytab entry, the entry can be either;
kerberos principal
A kerberos principal (identified by the presence of '@') is just added to the keytab
file.
machinename
A machinename (identified by the trailing '$') is used to create a a kerberos
principal 'machinename@realm' which is added to the keytab file.
serviceclass
A serviceclass (such as 'cifs', 'html' etc.) is used to create a pair of kerberos
principals 'serviceclass/fully_qualified_dns_name@realm' &
'serviceclass/netbios_name@realm' which are added to the keytab file.
Windows SPN
A Windows SPN is of the format 'serviceclass/host:port', it is used to create a
kerberos principal 'serviceclass/host@realm' which will be written to the keytab file.
Unlike old versions no computer AD objects are modified by this command. To preserve the
bevhaviour of older clients 'net ads keytab ad_update_ads' is available.
ADS KEYTAB ADD_UPDATE_ADS (principal | machine | serviceclass | windows SPN
Adds a new keytab entry (see section for net ads keytab add). In addition to adding
entries to the keytab file corrosponding Windows SPNs are created from the entry passed to
this command. These SPN(s) added to the AD computer account object associated with the
client machine running this command for the following entry types;
serviceclass
A serviceclass (such as 'cifs', 'html' etc.) is used to create a pair of Windows
SPN(s) 'param/full_qualified_dns' & 'param/netbios_name' which are added to the AD
computer account object for this client.
Windows SPN
A Windows SPN is of the format 'serviceclass/host:port', it is added as passed to the
AD computer account object for this client.
ADS setspn SETSPN LIST [machine]
Lists the Windows SPNs stored in the 'machine' Windows AD Computer object. If 'machine' is
not specified then computer account for this client is used instead.
ADS setspn SETSPN ADD SPN [machine]

is not specified then computer account for this client is used instead.
ADS setspn SETSPN DELETE SPN [machine]
DELETE the specified Window SPN from the 'machine' Windows AD Computer object. If
'machine' is not specified then computer account for this client is used instead.
ADS WORKGROUP
Print out workgroup name for specified kerberos realm.
ADS ENCTYPES
List, modify or delete the value of the "msDS-SupportedEncryptionTypes" attribute of an
account in AD.
This attribute allows one to control which Kerberos encryption types are used for the
generation of initial and service tickets. The value consists of an integer bitmask with
the following values:
0x00000001 DES-CBC-CRC
0x00000002 DES-CBC-MD5
0x00000004 RC4-HMAC
0x00000008 AES128-CTS-HMAC-SHA1-96
0x00000010 AES256-CTS-HMAC-SHA1-96

"delete" it in automatic mode.
USERSHARE
Starting with version 3.0.23, a Samba server now supports the ability for non-root users
to add user defined shares to be exported using the "net usershare" commands.
To set this up, first set up your /etc/samba/smb.conf by adding to the [global] section:
usershare path = /usr/local/samba/lib/usershares Next create the directory
/usr/local/samba/lib/usershares, change the owner to root and set the group owner to the
UNIX group who should have the ability to create usershares, for example a group called
"serverops". Set the permissions on /usr/local/samba/lib/usershares to 01770. (Owner and
group all access, no access for others, plus the sticky bit, which means that a file in
that directory can be renamed or deleted only by the owner of the file). Finally, tell
smbd how many usershares you will allow by adding to the [global] section of
/etc/samba/smb.conf a line such as : usershare max shares = 100. To allow 100 usershare
definitions. Now, members of the UNIX group "serverops" can create user defined shares on
demand using the commands below.
The usershare commands are:
net usershare add sharename path [comment [acl] [guest_ok=[y|n]]] - to add or change a
user defined share.
net usershare delete sharename - to delete a user defined share.
net usershare info [--long] [wildcard sharename] - to print info about a user defined
share.
net usershare list [--long] [wildcard sharename] - to list user defined shares.
USERSHARE ADD sharename path [comment] [acl] [guest_ok=[y|n]]
Add or replace a new user defined share, with name "sharename".
"path" specifies the absolute pathname on the system to be exported. Restrictions may be
put on this, see the global /etc/samba/smb.conf parameters: "usershare owner only",
"usershare prefix allow list", and "usershare prefix deny list".
The optional "comment" parameter is the comment that will appear on the share when browsed
to by a client.
The optional "acl" field specifies which users have read and write access to the entire
share. Note that guest connections are not allowed unless the /etc/samba/smb.conf
parameter "usershare allow guests" has been set. The definition of a user defined share
acl is: "user:permission", where user is a valid username on the system and permission can
be "F", "R", or "D". "F" stands for "full permissions", ie. read and write permissions.
"D" stands for "deny" for a user, ie. prevent this user from accessing this share. "R"
stands for "read only", ie. only allow read access to this share (no creation of new files
or directories or writing to files).
The default if no "acl" is given is "Everyone:R", which means any authenticated user has
read-only access.
The optional "guest_ok" has the same effect as the parameter of the same name in
/etc/samba/smb.conf, in that it allows guest access to this user defined share. This
parameter is only allowed if the global parameter "usershare allow guests" has been set to
true in the /etc/samba/smb.conf.
There is no separate command to modify an existing user defined share, just use the "net
usershare add [sharename]" command using the same sharename as the one you wish to modify
and specify the new options you wish. The Samba smbd daemon notices user defined share
modifications at connect time so will see the change immediately, there is no need to
restart smbd on adding, deleting or changing a user defined share.
USERSHARE DELETE sharename
Deletes the user defined share by name. The Samba smbd daemon immediately notices this
change, although it will not disconnect any users currently connected to the deleted
share.
USERSHARE INFO [--long] [wildcard sharename]
Get info on user defined shares owned by the current user matching the given pattern, or
all users.
net usershare info on its own dumps out info on the user defined shares that were created
by the current user, or restricts them to share names that match the given wildcard
pattern ('*' matches one or more characters, '?' matches only one character). If the
'--long' option is also given, it prints out info on user defined shares created by other
users.
The information given about a share looks like: [foobar] path=/home/jeremy comment=testme
usershare_acl=Everyone:F guest_ok=n And is a list of the current settings of the user
defined share that can be modified by the "net usershare add" command.
USERSHARE LIST [--long] wildcard sharename
List all the user defined shares owned by the current user matching the given pattern, or
all users.
net usershare list on its own list out the names of the user defined shares that were
created by the current user, or restricts the list to share names that match the given
wildcard pattern ('*' matches one or more characters, '?' matches only one character). If
the '--long' option is also given, it includes the names of user defined shares created by
other users.
[RPC] CONF
Starting with version 3.2.0, a Samba server can be configured by data stored in registry.
This configuration data can be edited with the new "net conf" commands. There is also the
possibility to configure a remote Samba server by enabling the RPC conf mode and
specifying the address of the remote server.
The deployment of this configuration data can be activated in two levels from the
/etc/samba/smb.conf file: Share definitions from registry are activated by setting
registry shares to “yes” in the [global] section and global configuration options are
activated by setting include = registry in the [global] section for a mixed configuration
or by setting config backend = registry in the [global] section for a registry-only
configuration. See the smb.conf(5) manpage for details.
The conf commands are:
net [rpc] conf list - Dump the complete configuration in smb.conf like format.
net [rpc] conf import - Import configuration from file in smb.conf format.
net [rpc] conf listshares - List the registry shares.
net [rpc] conf drop - Delete the complete configuration from registry.
net [rpc] conf showshare - Show the definition of a registry share.
net [rpc] conf addshare - Create a new registry share.
net [rpc] conf delshare - Delete a registry share.
net [rpc] conf setparm - Store a parameter.
net [rpc] conf getparm - Retrieve the value of a parameter.
net [rpc] conf delparm - Delete a parameter.
net [rpc] conf getincludes - Show the includes of a share definition.
net [rpc] conf setincludes - Set includes for a share.
net [rpc] conf delincludes - Delete includes from a share definition.
[RPC] CONF LIST
Print the configuration data stored in the registry in a smb.conf-like format to standard
output.
[RPC] CONF IMPORT [--test|-T] filename [section]
This command imports configuration from a file in smb.conf format. If a section
encountered in the input file is present in registry, its contents is replaced. Sections
of registry configuration that have no counterpart in the input file are not affected. If
you want to delete these, you will have to use the "net conf drop" or "net conf delshare"
commands. Optionally, a section may be specified to restrict the effect of the import
command to that specific section. A test mode is enabled by specifying the parameter "-T"
on the commandline. In test mode, no changes are made to the registry, and the resulting
configuration is printed to standard output instead.
[RPC] CONF LISTSHARES
List the names of the shares defined in registry.
[RPC] CONF DROP
Delete the complete configuration data from registry.
[RPC] CONF SHOWSHARE sharename
Show the definition of the share or section specified. It is valid to specify "global" as
sharename to retrieve the global configuration options from registry.
[RPC] CONF ADDSHARE sharename path [writeable={y|N} [guest_ok={y|N} [comment]]]
Create a new share definition in registry. The sharename and path have to be given. The
share name may not be "global". Optionally, values for the very common options
"writeable", "guest ok" and a "comment" may be specified. The same result may be obtained
by a sequence of "net conf setparm" commands.
[RPC] CONF DELSHARE sharename
Delete a share definition from registry.
[RPC] CONF SETPARM section parameter value
Store a parameter in registry. The section may be global or a sharename. The section is
created if it does not exist yet.
[RPC] CONF GETPARM section parameter
Show a parameter stored in registry.
[RPC] CONF DELPARM section parameter
Delete a parameter stored in registry.
[RPC] CONF GETINCLUDES section
Get the list of includes for the provided section (global or share).
Note that due to the nature of the registry database and the nature of include directives,
the includes need special treatment: Parameters are stored in registry by the parameter
name as valuename, so there is only ever one instance of a parameter per share. Also, a
specific order like in a text file is not guaranteed. For all real parameters, this is
perfectly ok, but the include directive is rather a meta parameter, for which, in the
smb.conf text file, the place where it is specified between the other parameters is very
important. This can not be achieved by the simple registry smbconf data model, so there is
one ordered list of includes per share, and this list is evaluated after all the
parameters of the share.
Further note that currently, only files can be included from registry configuration. In
the future, there will be the ability to include configuration data from other registry
keys.
[RPC] CONF SETINCLUDES section [filename]+
Set the list of includes for the provided section (global or share) to the given list of
one or more filenames. The filenames may contain the usual smb.conf macros like %I.
[RPC] CONF DELINCLUDES section
Delete the list of includes from the provided section (global or share).

EVENTLOG
Starting with version 3.4.0 net can read, dump, import and export native win32 eventlog
files (usually *.evt). evt files are used by the native Windows eventviewer tools.
The import and export of evt files can only succeed when eventlog list is used in
/etc/samba/smb.conf file. See the smb.conf(5) manpage for details.
The eventlog commands are:
net eventlog dump - Dump a eventlog *.evt file on the screen.
net eventlog import - Import a eventlog *.evt into the samba internal tdb based
representation of eventlogs.
net eventlog export - Export the samba internal tdb based representation of eventlogs
into an eventlog *.evt file.
EVENTLOG DUMP filename
Prints a eventlog *.evt file to standard output.
EVENTLOG IMPORT filename eventlog
Imports a eventlog *.evt file defined by filename into the samba internal tdb
representation of eventlog defined by eventlog. eventlog needs to part of the eventlog
list defined in /etc/samba/smb.conf. See the smb.conf(5) manpage for details.
EVENTLOG EXPORT filename eventlog
Exports the samba internal tdb representation of eventlog defined by eventlog to a
eventlog *.evt file defined by filename. eventlog needs to part of the eventlog list
defined in /etc/samba/smb.conf. See the smb.conf(5) manpage for details.
DOM
Starting with version 3.2.0 Samba has support for remote join and unjoin APIs, both client
and server-side. Windows supports remote join capabilities since Windows 2000.
In order for Samba to be joined or unjoined remotely an account must be used that is
either member of the Domain Admins group, a member of the local Administrators group or a
user that is granted the SeMachineAccountPrivilege privilege.
The client side support for remote join is implemented in the net dom commands which are:
net dom join - Join a remote computer into a domain.
net dom unjoin - Unjoin a remote computer from a domain.
net dom renamecomputer - Renames a remote computer joined to a domain.
DOM JOIN domain=DOMAIN ou=OU account=ACCOUNT password=PASSWORD reboot
Joins a computer into a domain. This command supports the following additional parameters:
• DOMAIN can be a NetBIOS domain name (also known as short domain name) or a DNS
domain name for Active Directory Domains. As in Windows, it is also possible to
control which Domain Controller to use. This can be achieved by appending the
DC name using the \ separator character. Example: MYDOM\MYDC. The DOMAIN
parameter cannot be NULL.
• OU can be set to a RFC 1779 LDAP DN, like
ou=mymachines,cn=Users,dc=example,dc=com in order to create the machine account
in a non-default LDAP container. This optional parameter is only supported when
joining Active Directory Domains.
• ACCOUNT defines a domain account that will be used to join the machine to the
domain. This domain account needs to have sufficient privileges to join
machines.
• PASSWORD defines the password for the domain account defined with ACCOUNT.
• REBOOT is an optional parameter that can be set to reboot the remote machine
after successful join to the domain.
Note that you also need to use standard net parameters to connect and authenticate to the
remote machine that you want to join. These additional parameters include: -S computer and
-U user.
Example: net dom join -S xp -U XP\\administrator%secret domain=MYDOM
account=MYDOM\\administrator password=topsecret reboot.
This example would connect to a computer named XP as the local administrator using
password secret, and join the computer into a domain called MYDOM using the MYDOM domain
administrator account and password topsecret. After successful join, the computer would
reboot.
DOM UNJOIN account=ACCOUNT password=PASSWORD reboot
Unjoins a computer from a domain. This command supports the following additional
parameters:
• ACCOUNT defines a domain account that will be used to unjoin the machine from
the domain. This domain account needs to have sufficient privileges to unjoin
machines.
• PASSWORD defines the password for the domain account defined with ACCOUNT.
• REBOOT is an optional parameter that can be set to reboot the remote machine
after successful unjoin from the domain.
Note that you also need to use standard net parameters to connect and authenticate to the
remote machine that you want to unjoin. These additional parameters include: -S computer
and -U user.
Example: net dom unjoin -S xp -U XP\\administrator%secret account=MYDOM\\administrator
password=topsecret reboot.
This example would connect to a computer named XP as the local administrator using
password secret, and unjoin the computer from the domain using the MYDOM domain
administrator account and password topsecret. After successful unjoin, the computer would
reboot.
DOM RENAMECOMPUTER newname=NEWNAME account=ACCOUNT password=PASSWORD reboot
Renames a computer that is joined to a domain. This command supports the following
additional parameters:
• NEWNAME defines the new name of the machine in the domain.
• ACCOUNT defines a domain account that will be used to rename the machine in the
domain. This domain account needs to have sufficient privileges to rename
machines.
• PASSWORD defines the password for the domain account defined with ACCOUNT.
• REBOOT is an optional parameter that can be set to reboot the remote machine
after successful rename in the domain.
Note that you also need to use standard net parameters to connect and authenticate to the
remote machine that you want to rename in the domain. These additional parameters include:
-S computer and -U user.
Example: net dom renamecomputer -S xp -U XP\\administrator%secret newname=XPNEW
account=MYDOM\\administrator password=topsecret reboot.
This example would connect to a computer named XP as the local administrator using
password secret, and rename the joined computer to XPNEW using the MYDOM domain
administrator account and password topsecret. After successful rename, the computer would
reboot.
G_LOCK
Manage global locks.
G_LOCK DO lockname timeout command
Execute a shell command under a global lock. This might be useful to define the order in
which several shell commands will be executed. The locking information is stored in a file
called g_lock.tdb. In setups with CTDB running, the locking information will be available
on all cluster nodes.
• LOCKNAME defines the name of the global lock.
• TIMEOUT defines the timeout.
• COMMAND defines the shell command to execute.
G_LOCK LOCKS
Print a list of all currently existing locknames.
G_LOCK DUMP lockname
Dump the locking table of a certain global lock.
TDB
Print information from tdb records.
TDB LOCKING key [DUMP]
List sharename, filename and number of share modes for a record from locking.tdb. With the
optional DUMP options, dump the complete record.
• KEY Key of the tdb record as hex string.

OFFLINEJOIN
Starting with version 4.15 Samba has support for offline join APIs. Windows supports
offline join capabilities since Windows 7 and Windows 2008 R2.
The following offline commands are implemented:
net offlinejoin provision - Provisions a machine account in AD.
net offlinejoin requestodj - Requests a domain offline join.
OFFLINEJOIN PROVISION domain=DOMAIN machine_name=MACHINE_NAME
machine_account_ou=MACHINE_ACCOUNT_OU dcname=DCNAME defpwd reuse savefile=FILENAME
printblob
Provisions a machine account in AD. This command needs network connectivity to the domain
controller to succeed. This command supports the following additional parameters:
• DOMAIN can be a NetBIOS domain name (also known as short domain name) or a DNS
domain name for Active Directory Domains. The DOMAIN parameter cannot be NULL.
• MACHINE_NAME defines the machine account name that will be provisioned in AD.
The MACHINE_NAME parameter cannot be NULL.
• MACHINE_ACCOUNT_OU can be set to a RFC 1779 LDAP DN, like
ou=mymachines,cn=Users,dc=example,dc=com in order to create the machine account
in a non-default LDAP container. This optional parameter is only supported when
joining Active Directory Domains.
• DCNAME defines a specific domain controller for creating the machine account in
AD.
• DEFPWD is an optional parameter that can be set to enforce using the default
machine account password. The use of this parameter is not recommended as the
default machine account password can be easily guessed.
• REUSE is an optional parameter that can be set to enforce reusing an existing
machine account in AD.
• SAVEFILE is an optional parameter to store the generated provisioning data on
disk.
• PRINTBLOB is an optional parameter to print the generated provisioning data on
stdout.
Example: net offlinejoin provision -U administrator%secret domain=MYDOM
machine_name=MYHOST savefile=provisioning.txt
OFFLINEJOIN REQUESTODJ loadfile=FILENAME
Requests an offline domain join by providing file-based provisioning data. This command
supports the following additional parameters:
• LOADFILE is a required parameter to load the provisioning from a file.
Example: net offlinejoin requestodj -U administrator%secret loadfile=provisioning.txt
