- -M
Searches for a master browser by looking
up the NetBIOS name name with a
type of 0x1d. If
name is "-" then it does a lookup on the special name
__MSBROWSE__. Please note that in order to
use the name "-", you need to make sure "-" isn't parsed as an
argument, e.g. use :
nmblookup -M -- -.
- -R
Set the recursion desired bit in the packet
to do a recursive lookup. This is used when sending a name
query to a machine running a WINS server and the user wishes
to query the names in the WINS server. If this bit is unset
the normal (broadcast responding) NetBIOS processing code
on a machine is used instead. See RFC1001, RFC1002 for details.
- -S
Once the name query has returned an IP
address then do a node status query as well. A node status
query returns the NetBIOS names registered by a host.
- -r
Try and bind to UDP port 137 to send and receive UDP
datagrams. The reason for this option is a bug in Windows 95
where it ignores the source port of the requesting packet
and only replies to UDP port 137. Unfortunately, on most UNIX
systems root privilege is needed to bind to this port, and
in addition, if the nmbd(8) daemon is running on this machine it also binds to this port.
- -A
Interpret name as
an IP Address and do a node status query on this address.
- -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.
- -i <scope>
This specifies a NetBIOS scope that
nmblookup will use to communicate with when
generating NetBIOS names. For details on the use of NetBIOS
scopes, see rfc1001.txt and rfc1002.txt. NetBIOS scopes are
very rarely used, only set this parameter
if you are the system administrator in charge of all the
NetBIOS systems you communicate with.
- -W|--workgroup=domain
Set the SMB domain of the username. This
overrides the default domain which is the domain defined in
smb.conf. If the domain specified is the same as the servers
NetBIOS name, it causes the client to log on using the servers local
SAM (as opposed to the Domain SAM).
- -O socket options
TCP socket options to set on the client
socket. See the socket options parameter in
the smb.conf manual page for the list of valid
options.
- -h|--help
Print a summary of command line options.
- -B <broadcast address>
Send the query to the given broadcast address. Without
this option the default behavior of nmblookup is to send the
query to the broadcast address of the network interfaces as
either auto-detected or defined in the interfaces
parameter of the smb.conf(5) file.
- -U <unicast address>
Do a unicast query to the specified address or
host unicast address. This option
(along with the -R option) is needed to
query a WINS server.
- -V
Prints the program version number.
- -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.
- -d|--debuglevel=level
level 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.
- -l|--logfile=logdirectory
Base directory name for log/debug files. The extension
".progname" will be appended (e.g. log.smbclient,
log.smbd, etc...). The log file is never removed by the client.
- -T
This causes any IP addresses found in the
lookup to be looked up via a reverse DNS lookup into a
DNS name, and printed out before each
IP address .... NetBIOS name
pair that is the normal output.
- -f
Show which flags apply to the name that has been looked up. Possible
answers are zero or more of: Response, Authoritative,
Truncated, Recursion_Desired, Recursion_Available, Broadcast.
- name
This is the NetBIOS name being queried. Depending
upon the previous options this may be a NetBIOS name or IP address.
If a NetBIOS name then the different name types may be specified
by appending '#<type>' to the name. This name may also be
'*', which will return all registered names within a broadcast
area.
