DESCRIPTION

15       This program is part of the samba(7) suite.
16
17       samba is the server daemon that provides Active Directory, filesharing
18       and printing services to clients. The server provides filespace and
19       directory services to clients using the SMB (or CIFS) protocol and
20       other related protocols such as DCE/RPC, LDAP and Kerberos.
21
22       Clients supported include MSCLIENT 3.0 for DOS, Windows for Workgroups,
23       Windows 95/98/ME, Windows NT, Windows 2000/XP/2003, OS/2, DAVE for
24       Macintosh, and cifsfs for Linux.
25
26       An extensive description of the services that the server can provide is
27       given in the man page for the configuration file controlling the
28       attributes of those services (see smb.conf(5). This man page will not
29       describe the services, but will concentrate on the administrative
30       aspects of running the server.
31
32       Please note that there are significant security implications to running
33       this server, and the smb.conf(5) manual page should be regarded as
34       mandatory reading before proceeding with installation.

OPTIONS

37       -D|--daemon
38           If specified, this parameter causes the server to operate as a
39           daemon. That is, it detaches itself and runs in the background,
40           fielding requests on the appropriate ports. Operating the server as
41           a daemon is the recommended way of running samba for servers that
42           provide more than casual use file and print services. This switch
43           is assumed if samba is executed on the command line of a shell.
44
45       -i|--interactive
46           If this parameter is specified it causes the server to run
47           "interactively", not as a daemon, even if the server is executed on
48           the command line of a shell. Setting this parameter negates the
49           implicit daemon mode when run from the command line.  samba also
50           logs to standard output, as if the -S parameter had been given.
51
52       -M|--model
53           This parameter can be used to specify the "process model" samba
54           should use. This determines how concurrent clients are handled.
55           Available process models include:
56
57                  ·   single
58
59                      All Samba services run in a single process. This is not
60                      recommended for production configurations.
61
62                  ·   standard
63
64                      A process is created for each Samba service, and for
65                      those services that support it (currently only LDAP and
66                      NETLOGON) a new processes is started for each new client
67                      connection.
68
69                  ·   prefork
70
71                      A process is started for each Samba service, and a fixed
72                      number of worker processes are started for those
73                      services that support it (currently only LDAP). The
74                      client connections are then shared amongst the worker
75                      processes. Requests for services not supporting prefork
76                      are handled by a single process for that service.
77
78                      The number of prefork worker processes started is
79                      controlled by the smb.conf(5) parameter prefork
80                      children, which defaults to 1.
81
82
83       --maximum-runtime=seconds
84           Set maximum runtime of the server process till autotermination in
85           seconds.
86
87       -b|--show-build
88           Print information about how Samba was built.
89
90       --usage
91           Display brief usage message.
92
93       --debug-stderr
94           Send debug output to STDERR.
95
96       --leak-report
97           Enable talloc leak reporting on exit.
98
99       --leak-report-full
100           Enable full talloc leak reporting on exit.
101
102       -d|--debuglevel=level
103           level is an integer from 0 to 10. The default value if this
104           parameter is not specified is 0.
105
106           The higher this value, the more detail will be logged to the log
107           files about the activities of the server. At level 0, only critical
108           errors and serious warnings will be logged. Level 1 is a reasonable
109           level for day-to-day running - it generates a small amount of
110           information about operations carried out.
111
112           Levels above 1 will generate considerable amounts of log data, and
113           should only be used when investigating a problem. Levels above 3
114           are designed for use only by developers and generate HUGE amounts
115           of log data, most of which is extremely cryptic.
116
117           Note that specifying this parameter here will override the log
118           level parameter in the smb.conf file.
119
120       -V|--version
121           Prints the program version number.
122
123       -s|--configfile=<configuration file>
124           The file specified contains the configuration details required by
125           the server. The information in this file includes server-specific
126           information such as what printcap file to use, as well as
127           descriptions of all the services that the server is to provide. See
128           smb.conf for more information. The default configuration file name
129           is determined at compile time.
130
131       -l|--log-basename=logdirectory
132           Base directory name for log/debug files. The extension ".progname"
133           will be appended (e.g. log.smbclient, log.smbd, etc...). The log
134           file is never removed by the client.
135
136       --option=<name>=<value>
137           Set the smb.conf(5) option "<name>" to value "<value>" from the
138           command line. This overrides compiled-in defaults and options read
139           from the configuration file.
140
141       -?|--help
142           Print a summary of command line options.
143
144       --usage
145           Display brief usage message.
146

FILES

148       /etc/rc
149           or whatever initialization script your system uses.
150
151           If running the server as a daemon at startup, this file will need
152           to contain an appropriate startup sequence for the server.
153
154       /etc/services
155           If running the server via the meta-daemon inetd, this file must
156           contain a mapping of service name (e.g., netbios-ssn) to service
157           port (e.g., 139) and protocol type (e.g., tcp).
158
159       /usr/local/samba/lib/smb.conf
160           This is the default location of the smb.conf(5) server
161           configuration file. Other common places that systems install this
162           file are /usr/samba/lib/smb.conf and /etc/samba/smb.conf.
163
164           This file describes all the services the server is to make
165           available to clients. See smb.conf(5) for more information.
166

DIAGNOSTICS

168       Most diagnostics issued by the server are logged in a specified log
169       file. The log file name is specified at compile time, but may be
170       overridden on the command line.
171
172       The number and nature of diagnostics available depends on the debug
173       level used by the server. If you have problems, set the debug level to
174       3 and peruse the log files.
175
176       Most messages are reasonably self-explanatory. Unfortunately, at the
177       time this man page was created, there are too many diagnostics
178       available in the source code to warrant describing each and every
179       diagnostic. At this stage your best bet is still to grep the source
180       code and inspect the conditions that gave rise to the diagnostics you
181       are seeing.

193       The original Samba software and related utilities were created by

195       Source project similar to the way the Linux kernel is developed.
