net

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.

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 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.
