DESCRIPTION

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

OPTIONS

39       -D|--daemon
40           If specified, this parameter causes the server to operate as a
41           daemon. That is, it detaches itself and runs in the background,
42           fielding requests on the appropriate ports. Operating the server as
43           a daemon is the recommended way of running samba for servers that
44           provide more than casual use file and print services. This switch
45           is assumed if samba is executed on the command line of a shell.
46
47       -F|--foreground
48           If specified, this parameter causes the samba process to not
49           daemonize, i.e. double-fork and disassociate with the terminal.
50
51       -i|--interactive
52           If this parameter is specified it causes the server to run
53           "interactively", not as a daemon, even if the server is executed on
54           the command line of a shell. Setting this parameter negates the
55           implicit daemon mode when run from the command line.  samba also
56           logs to standard output, as if the -S parameter had been given.
57
58       -M|--model
59           This parameter can be used to specify the "process model" samba
60           should use. This determines how concurrent clients are handled.
61           Available process models include:
62
63single
64
65                      All Samba services run in a single process. This is not
66                      recommended for production configurations.
67
68standard
69
70                      A process is created for each Samba service, and for
71                      those services that support it (currently only LDAP and
72                      NETLOGON) a new processes is started for each new client
73                      connection.
74
75                      Historically, this was the 'standard' way Samba behaved
76                      up until v4.10. Note that this model can be resource
77                      intensive if you have a large number of client
78                      connections.
79
80prefork
81
82                      The default. A process is started for each Samba
83                      service, and a fixed number of worker processes are
84                      started for those services that support it (currently
85                      LDAP, NETLOGON, and KDC). The client connections are
86                      then shared amongst the worker processes. Requests for
87                      services not supporting prefork are handled by a single
88                      process for that service.
89
90                      The number of prefork worker processes started is
91                      controlled by the smb.conf(5) parameter prefork
92                      children, which defaults to 4.
93
94
95       --maximum-runtime=seconds
96           Set maximum runtime of the server process till autotermination in
97           seconds.
98
99       -b|--show-build
100           Print information about how Samba was built.
101
102       -d|--debuglevel=DEBUGLEVEL, --debug-stdout
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.  This will redirect debug
119           output to STDOUT. By default server daemons are logging to a log
120           file.
121
122       --configfile=CONFIGFILE
123           The file specified contains the configuration details required by
124           the server. The information in this file includes server-specific
125           information such as what printcap file to use, as well as
126           descriptions of all the services that the server is to provide. See
127           smb.conf for more information. The default configuration file name
128           is determined at compile time.
129
130       --option=<name>=<value>
131           Set the smb.conf(5) option "<name>" to value "<value>" from the
132           command line. This overrides compiled-in defaults and options read
133           from the configuration file. If a name or a value includes a space,
134           wrap whole --option=name=value into quotes.
135
136       -l|--log-basename=logdirectory
137           Base directory name for log/debug files. The extension ".progname"
138           will be appended (e.g. log.smbclient, log.smbd, etc...). The log
139           file is never removed by the client.
140
141       --leak-report
142           Enable talloc leak reporting on exit.
143
144       --leak-report-full
145           Enable full talloc leak reporting on exit.
146
147       -V|--version
148           Prints the program version number.
149
150       -?|--help
151           Print a summary of command line options.
152
153       --usage
154           Display brief usage message.
155

FILES

157       /etc/rc
158           or whatever initialization script your system uses.
159
160           If running the server as a daemon at startup, this file will need
161           to contain an appropriate startup sequence for the server.
162
163       /etc/services
164           If running the server via the meta-daemon inetd, this file must
165           contain a mapping of service name (e.g., netbios-ssn) to service
166           port (e.g., 139) and protocol type (e.g., tcp).
167
168       /usr/local/samba/lib/smb.conf
169           This is the default location of the smb.conf(5) server
170           configuration file. Other common places that systems install this
171           file are /usr/samba/lib/smb.conf and /etc/samba/smb.conf.
172
173           This file describes all the services the server is to make
174           available to clients. See smb.conf(5) for more information.
175

DIAGNOSTICS

177       Most diagnostics issued by the server are logged in a specified log
178       file. The log file name is specified at compile time, but may be
179       overridden on the command line.
180
181       The number and nature of diagnostics available depends on the debug
182       level used by the server. If you have problems, set the debug level to
183       3 and peruse the log files.
184
185       Most messages are reasonably self-explanatory. Unfortunately, at the
186       time this man page was created, there are too many diagnostics
187       available in the source code to warrant describing each and every
188       diagnostic. At this stage your best bet is still to grep the source
189       code and inspect the conditions that gave rise to the diagnostics you
190       are seeing.
