- net - Tool for administration of Samba and remote CIFS servers.
- net
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.
- -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 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|--debuglevel=level
- level
is an integer from 0 to 10. The default value if this parameter is not specified is zero. smb.conf
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 thefile.

This man page is complete for version 3.0 of the Samba suite.
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.
The net manpage was written by Jelmer Vernooij.
