NET(8)
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]
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 pro-
tocol to use when executing a certain command. ADS is used for ActiveDirec-
tory, 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 op-
tion 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 pre-
cedence 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 informa-
tion 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 in-
formation. The default configuration file name is determined at com-
pile time.
-S server
Name of target server. You should specify either this option or a tar-
get 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 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 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 warn-
ing. YOU HAVE BEEN WARNED.
TIME
The NET TIME command allows you to view the time on a remote server or syn-
chronise 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.
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 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.
[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.

AUTHOR
The original Samba software and related utilities were created by Andrew
Tridgell. Samba is now developed by the Samba Team as an Open Source pro-
ject similar to the way the Linux kernel is developed.
The net manpage was written by Jelmer Vernooij.
