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 avail-
       able 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 printcap file to use, as well  as  descrip-
          tions  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 parame-
          ter 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 infor-
          mation 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  com-
       mand 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.


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

   [RPC|ADS]  JOIN [TYPE] [-U username[%password]] [createupn=UPN] [createcom-
       puter=OU] [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 may be created.

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

       [UPN] (ADS only) set the principalname attribute during the  join.  The
       default format is host/netbiosname@REALM.

       [OU] (ADS only) Precreate the computer account in a specific OU. The OU
       string reads from top to bottom without RDNs, and  is  delimited  by  a
       '/'. Please note that '' is used for escape by both the shell and ldap,
       so it may need to be doubled or quadrupled to pass through, and  it  is
       not used as a delimiter.

   [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.

   USERSHARE
       Starting  with  version 3.0.23, a Samba server now supports the ability
       for non-root users to add user define shares to be exported  using  the
       "net usershare" commands.

       To  set  this  up, first set up your smb.conf by adding to the [global]
       section : usershare path = /usr/local/samba/lib/usershares Next  create
       the directory /usr/local/samba/lib/usershares, change the owner to root
       and set the group owner to the UNIX group who should have  the  ability
       to  create  usershares, for example a group called "serverops". Set the
       permissions on /usr/local/samba/lib/usershares  to  01770.  (Owner  and
       group  all  access,  no  access  for others, plus the sticky bit, which
       means that a file in that directory can be renamed or deleted  only  by
       the owner of the file). Finally, tell smbd how many usershares you will
       allow by adding to the [global] section of smb.conf a line  such  as  :
       usershare  max  shares  = 100. To allow 100 usershare definitions. Now,
       members of the UNIX group "serverops" can create user defined shares on
       demand using the commands below.

       The usershare commands are:

          net  usershare add sharename path [comment] [acl] [guest_ok=[y|n]] -
          to add or change a user defined share.

          net usershare delete sharename - to delete a user defined share.

          net usershare info [-l|--long] [wildcard sharename] - to print  info
          about a user defined share.

          net  usershare  list [-l|--long] [wildcard sharename] - to list user
          defined shares.



   USERSHARE ADD sharename path [comment] [acl] [guest_ok=[y|n]]
       Add or replace a new user defined share, with name "sharename".

       "path" specifies the absolute pathname on the system  to  be  exported.
       Restrictions  may  be put on this, see the global smb.conf parameters :
       "usershare owner only", "usershare prefix allow list",  and  "usershare
       prefix deny list".

       The optional "comment" parameter is the comment that will appear on the
       share when browsed to by a client.

       The optional "acl" field specifies which  users  have  read  and  write
       access to the entire share. Note that guest connections are not allowed
       unless the smb.conf parameter "usershare allow guests"  has  been  set.
       The  definition  of  a  user  defined share acl is : "user:permission",
       where user is a valid username on the system and permission can be "F",
       "R", or "D". "F" stands for "full permissions", ie. read and write per-
       missions. "D" stands for "deny" for a user, ie. prevent this user  from
       accessing  this  share. "R" stands for "read only", ie. only allow read
       access to this share (no creation of new files or directories or  writ-
       ing to files).

       The  default  if  no  "acl"  is  given is "Everyone:R", which means any
       authenticated user has read-only access.

       The optional "guest_ok" has the same effect as  the  parameter  of  the
       same  name  in  smb.conf,  in  that it allows guest access to this user
       defined share. This parameter is only allowed if the  global  parameter
       "usershare allow guests" has been set to true in the smb.conf.


       There  is no separate command to modify an existing user defined share,
       just use the "net usershare add [sharename]"  command  using  the  same
       sharename as the one you wish to modify and specify the new options you
       wish. The Samba smbd daemon notices user defined share modifications at
       connect  time  so  will see the change immediately, there is no need to
       restart smbd on adding, deleting or changing a user defined share.


   USERSHARE DELETE sharename
       Deletes the user defined share by name. The Samba smbd  daemon  immedi-
       ately  notices  this  change, although it will not disconnect any users
       currently connected to the deleted share.


   USERSHARE INFO [-l|--long] [wildcard sharename]
       Get info on user defined shares owned by the current user matching  the
       given pattern, or all users.

       net usershare info on its own dumps out info on the user defined shares
       that were created by the current user, or restricts them to share names
       that  match the given wildcard pattern ('*' matches one or more charac-
       ters, '?' matches only one character). If the '-l' or  '--long'  option
       is  also  given,  it  prints out info on user defined shares created by
       other users.

       The  information  given  about  a   share   looks   like   :   [foobar]
       path=/home/jeremy  comment=testme  usershare_acl=Everyone:F  guest_ok=n
       And is a list of the current settings of the user  defined  share  that
       can be modified by the "net usershare add" command.


   USERSHARE LIST [-l|--long] wildcard sharename
       List all the user defined shares owned by the current user matching the
       given pattern, or all users.

       net usershare list on its own list out the names of  the  user  defined
       shares  that were created by the current user, or restricts the list to
       share names that match the given wildcard pattern ('*' matches  one  or
       more  characters,  '?'  matches  only  one  character).  If the '-l' or
       '--long' option is also given, it includes the names  of  user  defined
       shares created by other users.

   HELP [COMMAND]
       Gives usage information for the specified command.
