Manage network resources. net is part of the Samba suite.
Syntax
net {ads|rap|rpc} options...
Options
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 above. If this argument is omitted, net will try to determine
it automatically. Not all commands are available on all protocols.
-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 netbios name
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-spe-
cific information such as what printcap file 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|--debug=debuglevel
debuglevel 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 crit-
ical 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 smb.conf file.
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 re-
mote 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 re-
mote server using /bin/date.
TIME ZONE
Displays the timezone in hours from GMT on the remote computer.
[RPC|ADS] JOIN [TYPE] [-U username[%password]] [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 pass-
word will be prompted for, and a new account can be created.
[TYPE] can be PDC, BDC or MEMBER to specify the type of server joining
the domain.
[RPC] OLDJOIN [options]
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.

The Samba software suite is a collection of programs that implements the Server Message Block (commonly abbreviated as SMB) protocol for UNIX systems. This protocol is sometimes also referred to as the Common Internet File System (CIFS). Samba also implements the NetBIOS protocol in nmbd.
