NMBD !!!NMBD NAME SYNOPSIS DESCRIPTION OPTIONS FILES SIGNALS VERSION SEE ALSO AUTHOR ---- !!NAME nmbd - NetBIOS name server to provide NetBIOS over IP naming services to clients !!SYNOPSIS __nmbd__ [[ __-D__ ] [[ __-a__ ] [[ __-i__ ] [[ __-o__ ] [[ __-P__ ] [[ __-h__ ] [[ __-V__ ] [[ __-d __ ] [[ __-H __ ] [[ __-l __ ] [[ __-n __ ] [[ __-p __ ] [[ __-s __ ] !!DESCRIPTION This program is part of the Samba suite. __nmbd__ is a server that understands and can reply to NetBIOS over IP name service requests, like those produced by SMB/CIFS clients such as Windows 95/98/ME, Windows NT, Windows 2000, and !LanManager clients. It also participates in the browsing protocols which make up the Windows __ SMB/CIFS clients, when they start up, may wish to locate an SMB/CIFS server. That is, they wish to know what IP number a specified host is using. Amongst other services, __nmbd__ will listen for such requests, and if its own NetBIOS name is specified it will respond with the IP number of the host it is running on. Its __-n__ option (see OPTIONS below). Thus __nmbd__ will reply to broadcast queries for its own name(s). Additional names for __nmbd__ to respond on can be set via parameters in the ''smb.conf(5)''configuration file. __nmbd__ can also be used as a WINS (Windows Internet Name Server) server. What this basically means is that it will act as a WINS database server, creating a database from name registration requests that it receives and replying to queries from clients for these names. In addition, __nmbd__ can act as a WINS proxy, relaying broadcast queries from clients that do not understand how to talk the WINS protocol to a WIN server. !!OPTIONS __-D__ If specified, this parameter causes __nmbd__ to operate as a daemon. That is, it detaches itself and runs in the background, fielding requests on the appropriate port. By default, __nmbd__ will operate as a daemon if launched from a command shell. nmbd can also be operated from the __inetd__ meta-daemon, although this is not recommended. __-a__ If this parameter is specified, each new connection will append log messages to the log file. This is the default. __-i__ If this parameter is specified it causes the server to run __-o__ If this parameter is specified, the log files will be overwritten when opened. By default, __smbd__ will append entries to the log files. __-h__ Prints the help information (usage) for __nmbd__. __-H __ NetBIOS lmhosts file. The lmhosts file is a list of NetBIOS names to IP addresses that is loaded by the nmbd server and used via the name resolution mechanism name resolve order to resolve any NetBIOS name queries needed by the server. Note that the contents of this file are __NOT__ used by __nmbd__ to answer any name queries. Adding a line to this file affects name NetBIOS resolution from this host __ONLY__. The default path to this file is compiled into Samba as part of the build process. Common defaults are ''/usr/local/samba/lib/lmhosts'', ''/usr/samba/lib/lmhosts'' or ''/etc/lmhosts''. See the ''lmhosts(5)''man page for details on the contents of this file. __-V__ Prints the version number for __nmbd__. __-d __ 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 log level parameter in the ''smb.conf''file. __-l __ The -l parameter specifies a directory into which the nmbd__ server. The default log directory is compiled into Samba as part of the build process. Common defaults are ''/usr/local/samba/var/log.nmb'', ''/usr/samba/var/log.nmb'' or ''/var/log/log.nmb''. __-n __ This option allows you to override the NetBIOS name that Samba uses for itself. This is identical to setting the NetBIOS nameparameter in the ''smb.conf''file. However, a command line setting will take precedence over settings in ''smb.conf''. __-p __ UDP port number is a positive integer value. This option changes the default UDP port number (normally 137) that __nmbd__ responds to name queries on. Don't use this option unless you are an expert, in which case you won't need help! __-s __ The default configuration file name is set at build time, typically as ''/usr/local/samba/lib/smb.conf'', but this may be changed when Samba is autoconfigured. The file specified contains the configuration details required by the server. See ''smb.conf(5)''for more information. !!FILES ''/etc/inetd.conf'' If the server is to be run by the __inetd__ meta-daemon, this file must contain suitable startup information for the meta-daemon. See the UNIX_INSTALL.htmldocument for details. ''/etc/rc'' or whatever initialization script your system uses). If running the server as a daemon at startup, this file will need to contain an appropriate startup sequence for the server. See the UNIX_INSTALL.htmldocument for details. ''/etc/services'' If running the server via the meta-daemon __inetd__, this file must contain a mapping of service name (e.g., netbios-ssn) to service port (e.g., 139) and protocol type (e.g., tcp). See the UNIX_INSTALL.html document for details. ''/usr/local/samba/lib/smb.conf'' This is the default location of the ''smb.conf'' server configuration file. Other common places that systems install this file are ''/usr/samba/lib/smb.conf'' and ''/etc/smb.conf''. When run as a WINS server (see the wins support parameter in the ''smb.conf(5)'' man page), __nmbd__ will store the WINS database in the file ''wins.dat'' in the ''var/locks'' directory configured under wherever Samba was configured to install itself. If __nmbd__ is acting as a __browse master__ (see the local master parameter in the ''smb.conf(5)'' man page, __nmbd__ will store the browsing database in the file ''browse.dat'' in the ''var/locks'' directory configured under wherever Samba was configured to install itself. !!SIGNALS To shut down an __nmbd__ process it is recommended that SIGKILL (-9) __NOT__ be used, except as a last resort, as this may leave the name database in an inconsistent state. The correct way to terminate __nmbd__ is to send it a SIGTERM (-15) signal and wait for it to die on its own. __nmbd__ will accept SIGHUP, which will cause it to dump out its namelists into the file ''namelist.debug'' in the ''/usr/local/samba/var/locks'' directory (or the ''var/locks'' directory configured under wherever Samba was configured to install itself). This will also cause __nmbd__ to dump out its server database in the ''log.nmb'' file. The debug log level of nmbd may be raised or lowered using __smbcontrol(1)__ (SIGUSR[[1|2] signals are no longer used in Samba 2.2). This is to allow transient problems to be diagnosed, whilst still running at a normally low log level. !!VERSION This man page is correct for version 2.2 of the Samba suite. !!SEE ALSO __inetd(8)__, __smbd(8)__, ''smb.conf(5)'' , __smbclient(1)__ , and the Internet RFC's ''rfc1001.txt'', ''rfc1002.txt''. In addition the CIFS (formerly SMB) specification is available as a link from the Web page http://samba.org/cifs/ '' !!AUTHOR 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 original Samba man pages were written by Karl Auer. The man page sources were converted to YODL format (another excellent piece of Open Source software, available at ftp://ftp.icce.rug.nl/pub/unix/ ----
