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.

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.

Without any options, the NET Time command displays the time on the remote server. The remote server must be specified with the -S option.

Displays the time on the remote server in a format ready for /bin/date. The remote server must be specified with the -S option.

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.

Displays the timezone in hours from GMT on the remote server. The remote server must be specified with the -S option.

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.

[UPN] (ADS only) set the principalname attribute during the join. The default format is host/netbiosname@REALM.

[OU] (ADS only) Precreate the computer account in a specific OU. The OU string reads from top to bottom without RDNs, and is delimited by a '/'. Please note that '\' is used for escape by both the shell and ldap, so it may need to be doubled or quadrupled to pass through, and it is not used as a delimiter.

[PASS] (ADS only) Set a specific password on the computer account being created by the join.

[osName=string osVer=String] (ADS only) Set the operatingSystem and operatingSystemVersion attribute during the join. Both parameters must be specified for either to take effect.

Join a domain. Use the OLDJOIN option to join the domain using the old style of domain joining - you need to create a trust account in server manager first.

Force change of domain trust password.

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.

Remove interdomain trust account for DOMAIN. If it is used against localhost it has the same effect as smbpasswd -x 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.

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.

This command is no longer available in Samba 4.21.0 and newer. See sync machine password to keytab for replacement.

To replace e.g. call of

net ads keytab add wurst/brot@REALM

Add to smb.conf:

sync machine password to keytab = /path/to/keytab1:spns=wurst/brot@REALM:machine_password

and run:

net ads keytab create

Original description of this command:

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 behaviour of older clients 'net ads keytab ad_update_ads' is available.

This command is no longer available in Samba 4.21.0 and newer. See sync machine password to keytab for replacement.

To replace e.g. call of

net ads keytab delete wurst/brot@REALM

Delete from sync machine password to keytab principal "wurst/brot@REALM" and run:

net ads keytab create

This command is no longer available in Samba 4.21.0 and newer. See sync machine password to keytab for replacement.

To replace e.g. call of

net ads keytab add_update_ads wurst/brot@REALM

Add to smb.conf:

sync machine password to keytab = /path/to/keytab2:sync_spns:machine_password

and run:

net ads setspn add wurst/brot@REALM
net ads keytab create

Original description of this command:

Adds a new keytab entry (see section for net ads keytab add). In addition to adding entries to the keytab file corresponding 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.

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.

Print out workgroup name for specified kerberos realm.

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

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:

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.

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.

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.

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.

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:

Print the configuration data stored in the registry in a smb.conf-like format to standard output.

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.

List the names of the shares defined in registry.

Delete the complete configuration data from registry.

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.

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.

Delete a share definition from registry.

Store a parameter in registry. The section may be global or a sharename. The section is created if it does not exist yet.

Show a parameter stored in registry.

Delete a parameter stored in registry.

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.

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.

Delete the list of includes from the provided section (global or share).

Manipulate Samba's registry.

The registry commands are:

Enumerate subkeys and values of key.

Enumerate values of key and its subkeys.

Create a new key if not yet existing.

Delete the given key and its values from the registry, if it has no subkeys.

Delete the given key and all of its subkeys and values from the registry.

Output type and actual value of the value name of the given key.

Output the actual value of the value name of the given key.

Set the value name of an existing key. type may be one of sz, multi_sz or dword. In case of multi_sz value may be given multiple times.

Increment the DWORD value name of key by inc while holding a g_lock. inc defaults to 1.

Delete the value name of the given key.

Get the security descriptor of the given key.

Get the security descriptor of the given key as a Security Descriptor Definition Language (SDDL) string.

Set the security descriptor of the given key from a Security Descriptor Definition Language (SDDL) string sd.

Import a registration entries (.reg) file.

The following options are available:

--precheck check-file

This is a mechanism to check the existence or non-existence of certain keys or values specified in a precheck file before applying the import file. The import file will only be applied if the precheck succeeds.

The check-file follows the normal registry file syntax with the following semantics:

• <value name>=<value> checks whether the value exists and has the given value.
• <value name>=- checks whether the value does not exist.
• [key] checks whether the key exists.
• [-key] checks whether the key does not exist.

Export a key to a registration entries (.reg) file.

Convert a registration entries (.reg) file in.

Check and repair the registry database. If no option is given a read only check of the database is done. Among others an interactive or automatic repair mode may be chosen with one of the following options

-r|--repair

Interactive repair mode, ask a lot of questions.

-a|--auto

Noninteractive repair mode, use default answers.

-v|--verbose

Produce more output.

-T|--test

Dry run, show what changes would be made but don't touch anything.

-l|--lock

Lock the database while doing the check.

--reg-version={1,2,3}

Specify the format of the registry database. If not given it defaults to the value of the binary or, if an registry.tdb is explicitly stated at the commandline, to the value found in the INFO/version record.

[--db] <DB>

Check the specified database.

-o|--output <ODB>

Create a new registry database <ODB> instead of modifying the input. If <ODB> is already existing --wipe may be used to overwrite it.

--wipe

Replace the registry database instead of modifying the input or overwrite an existing output database.

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:

Prints a eventlog *.evt file to standard output.

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.

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.

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:

Joins a computer into a domain. This command supports the following additional parameters:

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.

Unjoins a computer from a domain. This command supports the following additional parameters:

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.

Renames a computer that is joined to a domain. This command supports the following additional parameters:

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.

Manage global locks.

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.

Print a list of all currently existing locknames.

Dump the locking table of a certain global lock.

Print information from tdb records.

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.

Access shared filesystem through the VFS.

Convert file streams to AppleDouble files.

• share A Samba share.
• path A relative path of something in the Samba share. "." can be used for the root directory of the share.

Options:

--recursive

Traverse a directory hierarchy.

--verbose

Verbose output.

--continue

Continue traversing a directory hierarchy if a single conversion fails.

--follow-symlinks

Follow symlinks encountered while traversing a directory.

Display the security descriptor of a file or directory.

• share A Samba share.
• path A relative path of something in the Samba share. "." can be used for the root directory of the share.

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:

Provisions a machine account in AD. This command needs network connectivity to the domain controller to succeed. This command supports the following additional parameters:

Example: net offlinejoin provision -U administrator%secret domain=MYDOM machine_name=MYHOST savefile=provisioning.txt

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

Starting with version 4.20 Samba has support for the SMB Witness service in a cluster.

The following witness commands are implemented:

List witness registrations from rpcd_witness_registration.tdb

Note: Only supported with clustering=yes!

Machine readable output can be generated with the following option:

--json

The selection of registrations can be limited by the following options:

--witness-registration=REGISTRATION_UUID

This does a direct lookup for REGISTRATION_UUID instead of doing a database traversal.

The following options all take a POSIX Extended Regular Expression, which can further filter the selection of registrations. These options are applied as logical AND, but each REGEX allows specifying multiple strings using the pipe symbol.

--witness-net-name=REGEX

This specifies the 'server name' the client registered for monitoring.

--witness-share-name=REGEX

This specifies the 'share name' the client registered for monitoring. Note that the share name is optional in the registration, otherwise an empty string is matched.

--witness-ip-address=REGEX

This specifies the ip address the client registered for monitoring.

--witness-client-computer-name=REGEX

This specifies the client computer name the client specified in the registration. Note it is just a string chosen by the client itself.

Generate client move notifications for witness registrations to a new ip or node

Note: Only supported with clustering=yes!

Machine readable output can be generated with the following option:

--json

The selection of registrations can be limited by the following options:

--witness-registration=REGISTRATION_UUID

This does a direct lookup for REGISTRATION_UUID instead of doing a database traversal.

The following options all take a POSIX Extended Regular Expression, which can further filter the selection of registrations. These options are applied as logical AND, but each REGEX allows specifying multiple strings using the pipe symbol.

--witness-ip-address=REGEX

This specifies the ip address the client registered for monitoring.

--witness-client-computer-name=REGEX

This specifies the client computer name the client specified in the registration. Note it is just a string chosen by the client itself.

If the update should be applied to all registrations it needs to be explicitly specified:

--witness-apply-to-all

This selects all registrations. Note: This is mutual exclusive to the above options.

The content of the CLIENT_MOVE notification contains ip addresses specified by (exactly one) of the following options:

--witness-new-node=NODEID

By specifying a NODEID all ip addresses currently available on the given node are included in the response. By specifying '-1' as NODEID all ip addresses of the cluster are included in the response.

--witness-new-ip=IPADDRESS

By specifying an IPADDRESS only the specified ip address is included in the response.

The selected registrations are removed on the server and any pending AsyncNotify request will get a NOT_FOUND error.

Typically this triggers a clean re-registration on the client.

Force an AsyncNotify response based on json input (mostly for testing)

This selects all registrations. Note: This is mutual exclusive to the above options.

Note this is designed for testing and debugging!

In short it is not designed to be used by administrators, but developers and automated tests.

By default an empty response with WERR_OK is generated, but basically any valid response can be specified by a specifying a JSON string:

--witness-forced-response=JSON

This allows the generation of very complex witness_notifyResponse structures.

As this is for developers, please read the code in order to understand all possible values of the JSON string format...

See 'net help witness force-response' for further details.
