It also -participates in the browsing protocols which make up the Windows -"Network Neighborhood" view. -<p>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. -<p>Amongst other services, <strong>nmbd</strong> 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 "own NetBIOS name" is by -default the primary DNS name of the host it is running on, but this -can be overridden with the <strong>-n</strong> option (see <a href="nmbd.8.html#OPTIONS">OPTIONS</a> below). Thus -<strong>nmbd</strong> will reply to broadcast queries for its own name(s). Additional -names for <strong>nmbd</strong> to respond on can be set via parameters in the -<a href="smb.conf.5.html"><strong>smb.conf(5)</strong></a> configuration file. -<p><strong>nmbd</strong> 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. -<p>In addition, <strong>nmbd</strong> 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. -<p><a name="OPTIONS"></a> -<h2>OPTIONS</h2> - -<p><dl> -<p><a name="minusD"></a> -<p></p><dt><strong><strong>-D</strong></strong><dd> If specified, this parameter causes <strong>nmbd</strong> to operate -as a daemon.

This will also cause <strong>nmbd</strong> to dump out it's server database in -the log.nmb file. In addition, the debug log level of nmbd may be raised -by sending it a SIGUSR1 (<code>kill -USR1 <nmbd-pid></code>) and lowered by sending it a -SIGUSR2 (<code>kill -USR2 <nmbd-pid></code>).

See the -section <a href="smbd.8.html#INSTALLATION">INSTALLATION</a> below. -<p><strong>/etc/services</strong> -<p>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 section -<a href="smbd.8.html#INSTALLATION">INSTALLATION</a> below. -<p><strong>/usr/local/samba/lib/smb.conf</strong> -<p>This is the default location of the <em>smb.conf</em> server configuration -file.

See <a href="smb.conf.5.html"><strong>smb.conf (5)</strong></a> for more information. -<p><a name="LIMITATIONS"></a> -<h2>LIMITATIONS</h2> - -<p>On some systems <strong>smbd</strong> cannot change uid back to root after a -setuid() call. Such systems are called "trapdoor" uid systems. If you -have such a system, you will be unable to connect from a client (such -as a PC) as two different users at once. Attempts to connect the -second user will result in "access denied" or similar. -<p><a name="ENVIRONMENTVARIABLES"></a> -<h2>ENVIRONMENT VARIABLES</h2> - -<p><strong>PRINTER</strong> -<p>If no printer name is specified to printable services, most systems -will use the value of this variable (or "lp" if this variable is not -defined) as the name of the printer to use. This is not specific to -the server, however. -<p><a name="INSTALLATION"></a> -<h2>INSTALLATION</h2> - -<p>The location of the server and its support files is a matter for -individual system administrators. The following are thus suggestions -only. -<p>It is recommended that the server software be installed under the -/usr/local/samba hierarchy, in a directory readable by all, writeable -only by root. The server program itself should be executable by all, -as users may wish to run the server themselves (in which case it will -of course run with their privileges). The server should NOT be -setuid. On some systems it may be worthwhile to make smbd setgid to an -empty group. This is because some systems may have a security hole -where daemon processes that become a user can be attached to with a -debugger. Making the smbd file setgid to an empty group may prevent -this hole from being exploited. This security hole and the suggested -fix has only been confirmed on old versions (pre-kernel 2.0) of Linux -at the time this was written. It is possible that this hole only -exists in Linux, as testing on other systems has thus far shown them -to be immune. -<p>The server log files should be put in a directory readable and -writeable only by root, as the log files may contain sensitive -information. -<p>The configuration file should be placed in a directory readable and -writeable only by root, as the configuration file controls security for -the services offered by the server. The configuration file can be made -readable by all if desired, but this is not necessary for correct -operation of the server and is not recommended. A sample configuration -file "smb.conf.sample" is supplied with the source to the server - -this may be renamed to "smb.conf" and modified to suit your needs. -<p>The remaining notes will assume the following: -<p><dl> -<p><li > <strong>smbd</strong> (the server program) installed in /usr/local/samba/bin -<p><li > <strong>smb.conf</strong> (the configuration file) installed in /usr/local/samba/lib -<p><li > log files stored in /var/adm/smblogs -<p></dl> -<p>The server may be run either as a daemon by users or at startup, or it -may be run from a meta-daemon such as inetd upon request. If run as a -daemon, the server will always be ready, so starting sessions will be -faster. If run from a meta-daemon some memory will be saved and -utilities such as the tcpd TCP-wrapper may be used for extra security. -For serious use as file server it is recommended that <strong>smbd</strong> be run -as a daemon. -<p>When you've decided, continue with either -<a href="smbd.8.html#RUNNINGTHESERVERASADAEMON">RUNNING THE SERVER AS A DAEMON</a> or -<a href="smbd.8.html#RUNNINGTHESERVERONREQUEST">RUNNING THE SERVER ON REQUEST</a>. -<p><a name="RUNNINGTHESERVERASADAEMON"></a> -<h2>RUNNING THE SERVER AS A DAEMON</h2> - -<p>To run the server as a daemon from the command line, simply put the -<a href="smbd.8.html#minusD"><strong>-D</strong></a> option on the command line. There is no need to place an -ampersand at the end of the command line - the <a href="smbd.8.html#minusD"><strong>-D</strong></a> option causes -the server to detach itself from the tty anyway. -<p>Any user can run the server as a daemon (execute permissions -permitting, of course). This is useful for testing purposes, and may -even be useful as a temporary substitute for something like ftp. When -run this way, however, the server will only have the privileges of the -user who ran it. -<p>To ensure that the server is run as a daemon whenever the machine is -started, and to ensure that it runs as root so that it can serve -multiple clients, you will need to modify the system startup -files. Wherever appropriate (for example, in /etc/rc), insert the -following line, substituting port number, log file location, -configuration file location and debug level as desired: -<p><code>/usr/local/samba/bin/smbd -D -l /var/adm/smblogs/log -s /usr/local/samba/lib/smb.conf</code> -<p>(The above should appear in your initialization script as a single line. -Depending on your terminal characteristics, it may not appear that way in -this man page. If the above appears as more than one line, please treat any -newlines or indentation as a single space or TAB character.) -<p>If the options used at compile time are appropriate for your system, -all parameters except <a href="smbd.8.html#minusD"><strong>-D</strong></a> may be -omitted. See the section <a href="smbd.8.html#OPTIONS">OPTIONS</a> above. -<p><a name="RUNNINGTHESERVERONREQUEST"></a> -<h2>RUNNING THE SERVER ON REQUEST</h2> - -<p>If your system uses a meta-daemon such as <strong>inetd</strong>, you can arrange to -have the smbd server started whenever a process attempts to connect to -it. This requires several changes to the startup files on the host -machine. If you are experimenting as an ordinary user rather than as -root, you will need the assistance of your system administrator to -modify the system files. -<p>You will probably want to set up the NetBIOS name server <a href="nmbd.8.html"><strong>nmbd</strong></a> at -the same time as <strong>smbd</strong>. To do this refer to the man page for -<a href="nmbd.8.html"><strong>nmbd (8)</strong></a>. -<p>First, ensure that a port is configured in the file <code>/etc/services</code>. The -well-known port 139 should be used if possible, though any port may be -used. -<p>Ensure that a line similar to the following is in <code>/etc/services</code>: -<p><code>netbios-ssn 139/tcp</code> -<p>Note for NIS/YP users - you may need to rebuild the NIS service maps -rather than alter your local <code>/etc/services file</code>. -<p>Next, put a suitable line in the file <code>/etc/inetd.conf</code> (in the unlikely -event that you are using a meta-daemon other than inetd, you are on -your own). Note that the first item in this line matches the service -name in <code>/etc/services</code>. Substitute appropriate values for your system -in this line (see <strong>inetd (8)</strong>): -<p><code>netbios-ssn stream tcp nowait root /usr/local/samba/bin/smbd -d1 -l/var/adm/smblogs/log -s/usr/local/samba/lib/smb.conf</code> -<p>(The above should appear in <code>/etc/inetd.conf</code> as a single -line. Depending on your terminal characteristics, it may not appear -that way in this man page. If the above appears as more than one -line, please treat any newlines or indentation as a single space or -TAB character.) -<p>Note that there is no need to specify a port number here, even if you -are using a non-standard port number. -<p>Lastly, edit the configuration file to provide suitable services. To -start with, the following two services should be all you need: -<p><pre> - - -[homes] - writeable = yes - -[printers] - writeable = no - printable = yes - path = /tmp - public = yes - - -</pre> - -<p>This will allow you to connect to your home directory and print to any -printer supported by the host (user privileges permitting). -<p><a name="TESTINGTHEINSTALLATION"></a> -<h2>TESTING THE INSTALLATION</h2> - -<p>If running the server as a daemon, execute it before proceeding. If -using a meta-daemon, either restart the system or kill and restart the -meta-daemon. Some versions of inetd will reread their configuration -tables if they receive a HUP signal. -<p>If your machine's name is "fred" and your name is "mary", you should -now be able to connect to the service <code>\\fred\mary</code>. -<p>To properly test and experiment with the server, we recommend using -the smbclient program (see -<a href="smbclient.1.html"><strong>smbclient (1)</strong></a>) and also going through -the steps outlined in the file <em>DIAGNOSIS.txt</em> in the <em>docs/</em> -directory of your Samba installation. -<p><a name="VERSION"></a> -<h2>VERSION</h2> - -<p>This man page is correct for version 2.0 of the Samba suite. -<p><a name="DIAGNOSTICS"></a> -<h2>DIAGNOSTICS</h2> - -<p>Most diagnostics issued by the server are logged in a specified log -file.

Level 1 is a reasonable level for +day to day running - it generates a small amount of +information about operations carried out. -.nf - +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 <URL:smb.conf.5.html#loglevel> parameter in the \fIsmb.conf(5)\fR <URL:smb.conf.5.html> file. +.TP +\fB-l <log file>\fR +If specified, \fBlog file\fR +specifies a log filename into which informational and debug +messages from the running server will be logged.

The default value if this parameter is not +specified is 139. -[homes] - writeable = yes +This number is the port number that will be +used when making connections to the server from client +software. The standard (well-known) port number for the +SMB over TCP is 139, hence the default. If you wish to +run the server as an ordinary user rather than +as root, most systems will require you to use a port +number greater than 1024 - ask your system administrator +for help if you are in this situation. -[printers] - writeable = no - printable = yes - path = /tmp - public = yes +In order for the server to be useful by most +clients, should you configure it on a port other +than 139, you will require port redirection services +on port 139, details of which are outlined in rfc1002.txt +section 4.3.5. +This parameter is not normally specified except +in the above situation. +.TP +\fB-s <configuration file>\fR +The file specified contains the +configuration details required by the server.

See \fIsmb.conf(5)\fR <URL:smb.conf.5.html> for more information. +.SH "LIMITATIONS" +.PP +On some systems \fBsmbd\fR cannot change uid back +to root after a setuid() call. Such systems are called +|[[quot ]]|trapdoor|[[quot ]]| uid systems. If you have such a system, +you will be unable to connect from a client (such as a PC) as +two different users at once. Attempts to connect the +second user will result in |[[quot ]]|access denied|[[quot ]]| or +similar. +.SH "ENVIRONMENTVARIABLES" +.TP +\fBPRINTER\fR +If no printer name is specified to +printable services, most systems will use the value of +this variable (or |[[quot ]]|lp|[[quot ]]| if this variable is +not defined) as the name of the printer to use. This +is not specific to the server, however. +.SH "INSTALLATION" +.PP +The location of the server and its support files +is a matter for individual system administrators. The following +are thus suggestions only. +.PP +It is recommended that the server software be installed +under the \fI/usr/local/samba/\fR hierarchy, +in a directory readable by all, writeable only by root. The server +program itself should be executable by all, as users may wish to +run the server themselves (in which case it will of course run +with their privileges). The server should NOT be setuid. On some +systems it may be worthwhile to make smbd setgid to an empty group. +This is because some systems may have a security hole where daemon +processes that become a user can be attached to with a debugger. +Making the smbd file setgid to an empty group may prevent +this hole from being exploited. This security hole and the suggested +fix has only been confirmed on old versions (pre-kernel 2.0) of Linux +at the time this was written. It is possible that this hole only +exists in Linux, as testing on other systems has thus far shown them +to be immune. +.PP +The server log files should be put in a directory readable and +writeable only by root, as the log files may contain sensitive +information. +.PP +The configuration file should be placed in a directory +readable and writeable only by root, as the configuration file +controls security for the services offered by the server. The +configuration file can be made readable by all if desired, but +this is not necessary for correct operation of the server and is +not recommended. A sample configuration file \fIsmb.conf.sample +\fRis supplied with the source to the server - this may +be renamed to \fIsmb.conf\fR and modified to suit +your needs. +.PP +The remaining notes will assume the following: +.TP 0.2i +\(bu +\fBsmbd\fR (the server program) +installed in \fI/usr/local/samba/bin\fR +.TP 0.2i +\(bu +\fIsmb.conf\fR (the configuration +file) installed in \fI/usr/local/samba/lib\fR +.TP 0.2i +\(bu +log files stored in \fI/var/adm/smblogs +\fR.PP +The server may be run either as a daemon by users +or at startup, or it may be run from a meta-daemon such as +\fBinetd\fR upon request. If run as a daemon, +the server will always be ready, so starting sessions will be +faster. If run from a meta-daemon some memory will be saved and +utilities such as the tcpd TCP-wrapper may be used for extra +security. For serious use as file server it is recommended +that \fBsmbd\fR be run as a daemon. +.PP +.PP +When you've decided, continue with either +.PP +.TP 0.2i +\(bu +RUNNING THE SERVER AS A DAEMON or +.TP 0.2i +\(bu +RUNNING THE SERVER ON REQUEST. +.SH "RUNNING THE SERVER AS A DAEMON" +.PP +To run the server as a daemon from the command +line, simply put the \fB-D\fR option on the +command line. There is no need to place an ampersand at +the end of the command line - the \fB-D\fR +option causes the server to detach itself from the tty +anyway. +.PP +Any user can run the server as a daemon (execute +permissions permitting, of course). This is useful for +testing purposes, and may even be useful as a temporary +substitute for something like ftp. When run this way, however, +the server will only have the privileges of the user who ran +it. +.PP +To ensure that the server is run as a daemon whenever +the machine is started, and to ensure that it runs as root +so that it can serve multiple clients, you will need to modify +the system startup files. Wherever appropriate (for example, in +\fI/etc/rc\fR), insert the following line, +substituting port number, log file location, configuration file +location and debug level as desired: +.PP +\fB/usr/local/samba/bin/smbd -D -l /var/adm/smblogs/log +-s /usr/local/samba/lib/smb.conf\fR +.PP +(The above should appear in your initialization script +as a single line. Depending on your terminal characteristics, +it may not appear that way in this man page. If the above appears +as more than one line, please treat any newlines or indentation +as a single space or TAB character.) +.PP +If the options used at compile time are appropriate for +your system, all parameters except \fB-D\fR may +be omitted. See the section OPTIONS above. +.SH "RUNNING THE SERVER ON REQUEST" +.PP +If your system uses a meta-daemon such as \fBinetd +\fR, you can arrange to have the smbd server started +whenever a process attempts to connect to it. This requires several +changes to the startup files on the host machine. If you are +experimenting as an ordinary user rather than as root, you will +need the assistance of your system administrator to modify the +system files. +.PP +You will probably want to set up the NetBIOS name server +\fBnmbd\fR <URL:nmbd.8.html> at +the same time as \fBsmbd\fR. To do this refer to the +man page for \fBnmbd(8)\fR + <URL:nmbd.8.html>. +.PP +First, ensure that a port is configured in the file +\fI/etc/services\fR. The well-known port 139 +should be used if possible, though any port may be used. +.PP +Ensure that a line similar to the following is in +\fI/etc/services\fR: +.PP +\fBnetbios-ssn 139/tcp\fR +.PP +Note for NIS/YP users - you may need to rebuild the +NIS service maps rather than alter your local \fI/etc/services +\fRfile. +.PP +Next, put a suitable line in the file \fI/etc/inetd.conf +\fR(in the unlikely event that you are using a meta-daemon +other than inetd, you are on your own). Note that the first item +in this line matches the service name in \fI/etc/services +\fR\&. Substitute appropriate values for your system +in this line (see \fBinetd(8)\fR): +.PP +\fBnetbios-ssn stream tcp nowait root /usr/local/samba/bin/smbd +-d1 -l/var/adm/smblogs/log -s/usr/local/samba/lib/smb.conf\fR +.PP +(The above should appear in \fI/etc/inetd.conf\fR +as a single line.
