Server to provide AD and SMB/CIFS services to clients
samba [-D] [-i] [-M
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.
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.
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.
This parameter can be used to specify the "process model" samba
should use. This determines how concurrent clients are handled.
Available process models include:
All Samba services run in a single process. This is not
recommended for production configurations.
A process is created for each Samba service, and for
those services that support it (currently only LDAP and
NETLOGON) a new processes is started for each new client
A process is started for each Samba service, and a fixed
number of worker processes are started for those
services that support it (currently only LDAP). The
client connections are then shared amongst the worker
processes. Requests for services not supporting prefork
are handled by a single process for that service.
The number of prefork worker processes started is
controlled by the smb.conf(5) parameter prefork
children, which defaults to 1.

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.
Prints the program version number.
/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.
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.
This man page is part of version 4.9.11-Debian of the Samba suite.

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.
