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.
-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:
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
,
which defaults to 4.
--maximum-runtime=seconds
Set maximum runtime of the server process till
autotermination in seconds.
-b|--show-build
Print information about how Samba was built.
&cmdline.common.samba.server;
&popt.autohelp;
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.
