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|--daemonIf 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.
-F|--foreground
If specified, this parameter causes the samba
process to not daemonize, i.e. double-fork and disassociate with the
terminal.
-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:
--maximum-runtime=seconds
•single
All Samba services run in a single process. This is not recommended for
production configurations.
•standard
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 connection.
Historically, this was the 'standard' way Samba behaved up until v4.10. Note
that this model can be resource intensive if you have a large number of client
connections.
•prefork
The default. A process is started for each Samba service, and a fixed number of
worker processes are started for those services that support it (currently
LDAP, NETLOGON, and KDC). 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
4.
Set maximum runtime of the server process till
autotermination in seconds.
-b|--show-build
Print information about how Samba was
built.
-d|--debuglevel=DEBUGLEVEL, --debug-stdout
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 /etc/samba/smb.conf file. This will redirect debug output to
STDOUT. By default server daemons are logging to a log file.
--configfile=CONFIGFILE
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
/etc/samba/smb.conf for more information. The default configuration file name
is determined at compile time.
--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. If a name or a value includes a space, wrap whole
--option=name=value into quotes.
-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.
--leak-report
Enable talloc leak reporting on exit.
--leak-report-full
Enable full talloc leak reporting on
exit.
-V|--version
Prints the program version number.
-?|--help
Print a summary of command line options.
--usage
Display brief usage message.
FILES
/etc/rcor 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
