## Name

net — Tool for administration of Samba and remote CIFS servers.

## Synopsis

`net` {<ads|rap|rpc>} [-h] [-w workgroup] [-W myworkgroup] [-U user] [-I ip-address] [-p port] [-n myname] [-s conffile] [-S server] [-l] [-P] [-d debuglevel] [-V]

## 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.

## OPTIONS

-h|--help

  Print a summary of command line options.

-w target-workgroup

  Sets target workgroup or domain. You have to specify either this option or the IP address or the name of a server.

-W workgroup

  Sets client workgroup or domain

-U user

  User name to use

-I ip-address

  IP address of target server to use. You have to specify either this option or a target workgroup or a target server.

-p port

  Port on the target server to connect to (usually 139 or 445). Defaults to trying 445 first, then 139.

-n <primary NetBIOS name>

  This option allows you to override the NetBIOS name that Samba uses for itself. This is identical to setting the parameter in the `smb.conf` file. However, a command line setting will take precedence over settings in `smb.conf`.

-s <configuration file>

  The file specified contains the configuration details required by the server. The information in this file includes server-specific information such as what printers database to use, as well as descriptions of all the services that the server is to provide. See `smb.conf` for more information. The default configuration file name is determined at compile time.

-S server

  Name of target server. You should specify either this option or a target workgroup or a target IP address.

-l

  When listing data, give more information on each item.

-P

  Make queries to the external server using the machine account of the local server.

-d|--debuglevel=level

  `level` is an integer from 0 to 10. The default value if this parameter is not specified is zero.

  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 parameter in the `smb.conf` file.

## 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.

#### TIME SYSTEM

Displays the time on the remote server in a format ready for /bin/date

#### TIME SET

Tries to set the date and time of the local server to that on the remote server using /bin/date.

Displays the timezone in hours from GMT on the remote computer.

### [RPC|ADS] JOIN [TYPE] [-U username[%password]] [options]

[TYPE] may be PDC, BDC or MEMBER to specify the type of server joining the domain.
