| 37 | \fBnmblookup\fR is used to query NetBIOS names and map them to IP addresses in a network using NetBIOS over TCP/IP queries\&. The options allow the name queries to be directed at a particular IP broadcast area or to a particular machine\&. All queries are done over UDP\&.

| 43 | Searches for a master browser by looking up the NetBIOS name \fIname\fR with a type of \fB0x1d\fR\&. If \fI name\fR is "\-" then it does a lookup on the special name\fB__MSBROWSE__\fR\&. Please note that in order to use the name "\-", you need to make sure "\-" isn't parsed as an argument, e\&.g\&. use :\fBnmblookup \-M \-\- \-\fR\&.

| 47 | 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\&.

| 51 | 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\&.

| 55 | 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 \fBnmbd\fR(8) daemon is running on this machine it also binds to this port\&.

| 62 | \-n <primary NetBIOS name>
|
|---|
| 63 | This option allows you to override the NetBIOS name that Samba uses for itself\&. This is identical to setting the parameter in the \fIsmb\&.conf\fR file\&. However, a command line setting will take precedence over settings in \fIsmb\&.conf\fR\&.

| 66 | \-i <scope>
|
|---|
| 67 | This specifies a NetBIOS scope that \fBnmblookup\fR 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 \fBvery\fR rarely used, only set this parameter if you are the system administrator in charge of all the NetBIOS systems you communicate with\&.

| 70 | \-W|\-\-workgroup=domain
|
|---|
| 71 | 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)\&.

| 82 | \-B <broadcast address>
|
|---|
| 83 | 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 \fIinterfaces\fR parameter of the \fBsmb\&.conf\fR(5) file\&.

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 \fIsmb\&.conf\fR for more information\&. The default configuration file name is determined at compile time\&.

|
|---|
| 100 |
|
|---|
| 101 | 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\&.
|
|---|
| 102 |
|
|---|
| 103 | 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\&.
