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.

[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.

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:

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:

[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).

--wipe

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:

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:

DOM JOIN domain=DOMAIN ou=OU account=ACCOUNT password=PASSWORD reboot¶

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.

DOM UNJOIN account=ACCOUNT password=PASSWORD 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.

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:

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.

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.

vfs¶

Access shared filesystem through the VFS.

vfs stream2abouble [--recursive] [--verbose] [--continue] [--follow-symlinks] share path¶

Convert file streams to AppleDouble files.

Options:

--recursive

--verbose

--continue

--follow-symlinks

vfs getntacl share path¶

Display the security descriptor of a file or directory.

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:

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:

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:

Example: net offlinejoin requestodj -U administrator%secret loadfile=provisioning.txt

HELP [COMMAND]¶

Gives usage information for the specified command.
