NAME

       samba - Server to provide AD and SMB/CIFS services to clients

SYNOPSIS

       samba [-D] [-i] [-M <model>] [--maximum-runtime=<seconds>] [-b] [--help] [--usage] [-d <debug level>]
        [--debug-stderr] [-s <configuration file>] [--option=<smb_conf_param>=<value>] [-l <log directory>]
        [--leak-report] [--leak-report-full] [-V]

DESCRIPTION

       This program is part of the samba(7) suite.

       samba is the server daemon that provides Active Directory, filesharing and printing services to clients.
       The server provides filespace and directory services to clients using the SMB (or CIFS) protocol and
       other related protocols such as DCE/RPC, LDAP and Kerberos.

       Clients supported include MSCLIENT 3.0 for DOS, Windows for Workgroups, Windows 95/98/ME, Windows NT,
       Windows 2000/XP/2003, OS/2, DAVE for Macintosh, and cifsfs for Linux.

       An extensive description of the services that the server can provide is given in the man page for the
       configuration file controlling the attributes of those services (see smb.conf(5). This man page will not
       describe the services, but will concentrate on the administrative aspects of running the server.

       Please note that there are significant security implications to running this server, and the smb.conf(5)
       manual page should be regarded as mandatory reading before proceeding with installation.

OPTIONS

       -D|--daemon
           If specified, this parameter causes the server to operate as a daemon. That is, it detaches itself
           and runs in the background, fielding requests on the appropriate ports. Operating the server as a
           daemon is the recommended way of running samba for servers that provide more than casual use file and
           print services. This switch is assumed if samba is executed on the command line of a shell.

       -i|--interactive
           If this parameter is specified it causes the server to run "interactively", not as a daemon, even if
           the server is executed on the command line of a shell. Setting this parameter negates the implicit
           daemon mode when run from the command line.  samba also logs to standard output, as if the -S
           parameter had been given.

       -M model
           This parameter can be used to specify the "process model" samba should use. This determines how
           concurrent clients are handled. Available process models include single (everything in a single
           process), standard (similar behaviour to that of Samba 3), thread (single process, different threads.

       --maximum-runtime=seconds
           Set maximum runtime of the server process till autotermination in seconds.

       -b|--show-build
           Print information about how Samba was built.

       --usage
           Display brief usage message.

       --debug-stderr
           Send debug output to STDERR.

       --leak-report
           Enable talloc leak reporting on exit.

       --leak-report-full
           Enable full talloc leak reporting on exit.

       -d|--debuglevel=level
           level is an integer from 0 to 10. The default value if this parameter is not specified is 0.

           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.

       -V|--version
           Prints the program version number.

       -s|--configfile=<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.

       -l|--log-basename=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.

       --option=<name>=<value>
           Set the smb.conf(5) option "<name>" to value "<value>" from the command line. This overrides
           compiled-in defaults and options read from the configuration file.

       -?|--help
           Print a summary of command line options.

       --usage
           Display brief usage message.

FILES

       /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.

       /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).

       /usr/local/samba/lib/smb.conf
           This is the default location of the smb.conf(5) server configuration file. Other common places that
           systems install this file are /usr/samba/lib/smb.conf and /etc/samba/smb.conf.

           This file describes all the services the server is to make available to clients. See smb.conf(5) for
           more information.

DIAGNOSTICS

       Most diagnostics issued by the server are logged in a specified log file. The log file name is specified
       at compile time, but may be overridden on the command line.

       The number and nature of diagnostics available depends on the debug level used by the server. If you have
       problems, set the debug level to 3 and peruse the log files.

       Most messages are reasonably self-explanatory. Unfortunately, at the time this man page was created,
       there are too many diagnostics available in the source code to warrant describing each and every
       diagnostic. At this stage your best bet is still to grep the source code and inspect the conditions that
       gave rise to the diagnostics you are seeing.

VERSION

       This man page is correct for version 4 of the Samba suite.
