net

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 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 NetBIOS name parameter in the smb.conf(5) file. However, a command line setting will take precedence over settings in smb.conf(5).

-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 printcap file to use, as well as descriptions of all the services that the server is to provide. See smb.conf(5) 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 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(5) file.

COMMANDS

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.

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.
