This program is part of the samba
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
Please note that there are significant security implications to running this
server, and the smb.conf

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 single
(everything in a single process), standard (similar behaviour to that
of Samba 3), thread (single process, different threads.

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

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

extension ".progname" will be appended (e.g. log.smbclient,
log.smbd, etc...). The log file is never removed by the client.

If running the server as a daemon at startup, this file will need to contain an
appropriate startup sequence for the server.
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).
This is the default location of the

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
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
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.

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.
