8 nmbd \- NetBIOS name server to provide NetBIOS over IP naming services to clients
11 \fBsmbd\fR [ \fB-D\fR ] [ \fB-a\fR ] [ \fB-o\fR ] [ \fB-P\fR ] [ \fB-h\fR ] [ \fB-V\fR ] [ \fB-d <debug level>\fR ] [ \fB-H <lmhosts file>\fR ] [ \fB-l <log file>\fR ] [ \fB-n <primary netbios name>\fR ] [ \fB-p <port number>\fR ] [ \fB-s <configuration file>\fR ]
14 This program is part of the Samba suite.
16 \fBnmbd\fR is a server that understands
17 and can reply to NetBIOS over IP name service requests, like
18 those produced by SMB/CIFS clients such as Windows 95/98/ME,
19 Windows NT, Windows 2000, and LanManager clients. It also
20 participates in the browsing protocols which make up the
21 Windows "Network Neighborhood" view.
23 SMB/CIFS clients, when they start up, may wish to
24 locate an SMB/CIFS server. That is, they wish to know what
25 IP number a specified host is using.
27 Amongst other services, \fBnmbd\fR will
28 listen for such requests, and if its own NetBIOS name is
29 specified it will respond with the IP number of the host it
30 is running on. Its "own NetBIOS name" is by
31 default the primary DNS name of the host it is running on,
32 but this can be overridden with the \fB-n\fR
33 option (see OPTIONS below). Thus \fBnmbd\fR will
34 reply to broadcast queries for its own name(s). Additional
35 names for \fBnmbd\fR to respond on can be set
36 via parameters in the \fI smb.conf(5)\fRconfiguration file.
38 \fBnmbd\fR can also be used as a WINS
39 (Windows Internet Name Server) server. What this basically means
40 is that it will act as a WINS database server, creating a
41 database from name registration requests that it receives and
42 replying to queries from clients for these names.
44 In addition, \fBnmbd\fR can act as a WINS
45 proxy, relaying broadcast queries from clients that do
46 not understand how to talk the WINS protocol to a WIN
51 If specified, this parameter causes
52 \fBnmbd\fR to operate as a daemon. That is,
53 it detaches itself and runs in the background, fielding
54 requests on the appropriate port. By default, \fBnmbd\fR
55 will operate as a daemon if launched from a command shell.
56 nmbd can also be operated from the \fBinetd\fR
57 meta-daemon, although this is not recommended.
60 If this parameter is specified, each new
61 connection will append log messages to the log file.
65 If this parameter is specified, the
66 log files will be overwritten when opened. By default,
67 \fBsmbd\fR will append entries to the log
71 Prints the help information (usage)
75 NetBIOS lmhosts file. The lmhosts
76 file is a list of NetBIOS names to IP addresses that
77 is loaded by the nmbd server and used via the name
78 resolution mechanism name resolve orderto resolve any NetBIOS name queries needed by the server. Note
79 that the contents of this file are \fBNOT\fR
80 used by \fBnmbd\fR to answer any name queries.
81 Adding a line to this file affects name NetBIOS resolution
82 from this host \fBONLY\fR.
84 The default path to this file is compiled into
85 Samba as part of the build process. Common defaults
86 are \fI/usr/local/samba/lib/lmhosts\fR,
87 \fI/usr/samba/lib/lmhosts\fR or
88 \fI/etc/lmhosts\fR. See the \fIlmhosts(5)\fRman page for details on the
89 contents of this file.
92 Prints the version number for
95 \fB-d <debug level>\fR
96 debuglevel is an integer
97 from 0 to 10. The default value if this parameter is
98 not specified is zero.
100 The higher this value, the more detail will
101 be logged to the log files about the activities of the
102 server. At level 0, only critical errors and serious
103 warnings will be logged. Level 1 is a reasonable level for
104 day to day running - it generates a small amount of
105 information about operations carried out.
107 Levels above 1 will generate considerable amounts
108 of log data, and should only be used when investigating
109 a problem. Levels above 3 are designed for use only by developers
110 and generate HUGE amounts of log data, most of which is extremely
113 Note that specifying this parameter here will override
114 the log levelparameter in the \fI smb.conf\fRfile.
117 The -l parameter specifies a path
118 and base filename into which operational data from
119 the running \fBnmbd\fR server will
120 be logged. The actual log file name is generated by
121 appending the extension ".nmb" to the specified base
122 name. For example, if the name specified was "log"
123 then the file log.nmb would contain the debugging data.
125 The default log file path is compiled into Samba as
126 part of the build process. Common defaults are \fI /usr/local/samba/var/log.nmb\fR, \fI /usr/samba/var/log.nmb\fR or
127 \fI/var/log/log.nmb\fR.
129 \fB-n <primary NetBIOS name>\fR
130 This option allows you to override
131 the NetBIOS name that Samba uses for itself. This is identical
132 to setting the NetBIOS nameparameter in the
133 \fIsmb.conf\fRfile. However, a command
134 line setting will take precedence over settings in
137 \fB-p <UDP port number>\fR
138 UDP port number is a positive integer value.
139 This option changes the default UDP port number (normally 137)
140 that \fBnmbd\fR responds to name queries on. Don't
141 use this option unless you are an expert, in which case you
144 \fB-s <configuration file>\fR
145 The default configuration file name
146 is set at build time, typically as \fI /usr/local/samba/lib/smb.conf\fR, but
147 this may be changed when Samba is autoconfigured.
149 The file specified contains the configuration details
150 required by the server. See
151 \fIsmb.conf(5)\fRfor more information.
154 \fB\fI/etc/inetd.conf\fB\fR
155 If the server is to be run by the
156 \fBinetd\fR meta-daemon, this file
157 must contain suitable startup information for the
158 meta-daemon. See the section INSTALLATION below.
161 or whatever initialization script your
164 If running the server as a daemon at startup,
165 this file will need to contain an appropriate startup
166 sequence for the server. See the section INSTALLATION
169 \fB\fI/etc/services\fB\fR
170 If running the server via the
171 meta-daemon \fBinetd\fR, this file
172 must contain a mapping of service name (e.g., netbios-ssn)
173 to service port (e.g., 139) and protocol type (e.g., tcp).
174 See the section INSTALLATION below.
176 \fB\fI/usr/local/samba/lib/smb.conf\fB\fR
177 This is the default location of the
178 \fIsmb.conf\fRserver configuration file. Other common places that systems
179 install this file are \fI/usr/samba/lib/smb.conf\fR
180 and \fI/etc/smb.conf\fR.
182 When run as a WINS server (see the
183 wins supportparameter in the \fI smb.conf(5)\fRman page), \fBnmbd\fR
184 will store the WINS database in the file \fIwins.dat\fR
185 in the \fIvar/locks\fR directory configured under
186 wherever Samba was configured to install itself.
188 If \fBnmbd\fR is acting as a \fB browse master\fR (see the local masterparameter in the \fI smb.conf(5)\fRman page), \fBnmbd\fR
189 will store the browsing database in the file \fIbrowse.dat
190 \fRin the \fIvar/locks\fR directory
191 configured under wherever Samba was configured to install itself.
194 To shut down an \fBnmbd\fR process it is recommended
195 that SIGKILL (-9) \fBNOT\fR be used, except as a last
196 resort, as this may leave the name database in an inconsistent state.
197 The correct way to terminate \fBnmbd\fR is to send it
198 a SIGTERM (-15) signal and wait for it to die on its own.
200 \fBnmbd\fR will accept SIGHUP, which will cause
201 it to dump out it's namelists into the file \fInamelist.debug
202 \fRin the \fI/usr/local/samba/var/locks\fR
203 directory (or the \fIvar/locks\fR directory configured
204 under wherever Samba was configured to install itself). This will also
205 cause \fBnmbd\fR to dump out it's server database in
206 the \fIlog.nmb\fR file. In addition, the debug log level
207 of nmbd may be raised by sending it a SIGUSR1 (\fBkill -USR1
208 <nmbd-pid>\fR) and lowered by sending it a
209 SIGUSR2 (\fBkill -USR2 <nmbd-pid>\fR). This is to
210 allow transient problems to be diagnosed, whilst still running at a
211 normally low log level.
214 This man page is correct for version 2.2 of
218 \fBinetd(8)\fR, \fBsmbd(8)\fR,
221 \fR, and the Internet RFC's
222 \fIrfc1001.txt\fR, \fIrfc1002.txt\fR.

228 The original Samba software and related utilities
229 were created by Andrew Tridgell. Samba is now developed
230 by the Samba Team as an Open Source project similar
231 to the way the Linux kernel is developed.
233 The original Samba man pages were written by Karl Auer.
234 The man page sources were converted to YODL format (another
235 excellent piece of Open Source software, available at
236 ftp://ftp.icce.rug.nl/pub/unix/ <URL:ftp://ftp.icce.rug.nl/pub/unix/>) and updated for the Samba 2.0
237 release by Jeremy Allison. The conversion to DocBook for
238 Samba 2.2 was done by Gerald Carter
