net — Tool for administration of Samba and remote CIFS servers.
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]
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.
Print a summary of command line options.
Sets target workgroup or domain. You have to specify either this option or the IP address or the name of a server.
Sets client workgroup or domain
User name to use
IP address of target server to use. You have to specify either this option or a target workgroup or a target server.
Port on the target server to connect to (usually 139 or 445). Defaults to trying 445 first, then 139.
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.
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 for more information. The default configuration file name is determined at compile time.
Name of target server. You should specify either this option or a target workgroup or a target IP address.
When listing data, give more information on each item.
Make queries to the external server using the machine account of the local server.
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 parameter in the smb.conf file.
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.
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.
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.
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.
Enumerates all exported resources (network shares) on target server.
Validate whether the specified user can log in to the remote server. If the password is not specified on the commandline, it will be prompted.
Currently NOT implemented.
Execute the specified command on the remote server. Only works with OS/2 servers.
Currently NOT implemented.
Samba uses a general caching interface called 'gencache'. It can be controlled using 'NET CACHE'.
All the timeout parameters support the suffixes:
s - Seconds |
m - Minutes |
h - Hours |
d - Days |
w - Weeks |
Print the SID of the specified domain, or if the parameter is omitted, the SID of the domain the local server is in.
Manage the mappings between Windows group SIDs and UNIX groups. Parameters take the for "parameter=value". Common options include:
unixgroup - Name of the UNIX group
ntgroup - Name of the Windows NT group (must be resolvable to a SID
rid - Unsigned 32-bit integer
sid - Full SID in the form of "S-1-..."
type - Type of the group; either 'domain', 'local', or 'builtin'
comment - Freeform text description of the group
Add a new group mapping entry
net groupmap add {rid=int|sid=string} unixgroup=string [type={domain|local}] [ntgroup=string] [comment=string]
Delete a group mapping entry. If more then one group name matches, the first entry found is deleted.
net groupmap delete {ntgroup=string|sid=SID}
Prints out the highest RID currently in use on the local server (by the active 'passdb backend').
Print information about the domain of the remote server, such as domain name, domain sid and number of users and groups.
Remove interdomain trust account for DOMAIN from the remote server.
Currently NOT implemented.
Shut down the remote server.
Reboot after shutdown.
Force shutting down all applications.
Timeout before system will be shut down. An interactive user of the system can use this time to cancel the shutdown.
Display the specified message on the screen to announce the shutdown.
Export users, aliases and groups from remote server to local server. Can only be run an a BDC.
Print out status of machine account of the local machine in ADS. Prints out quite some debug info. Aimed at developers, regular users should use NET ADS TESTJOIN.
Perform a raw LDAP search on a ADS server and dump the results. The expression is a standard LDAP search expression, and the attributes are a list of LDAP fields to show in the results.
Example: net ads search '(objectCategory=group)' sAMAccountName
