15 This program is part of the samba(7) suite.
16 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 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 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 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.

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 -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 -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 · single
58 All Samba services run in a single process. This is not
60 recommended for production configurations.
61 · standard
63 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 Historically, this was the 'standard' way Samba behaved
70 up until v4.10. Note that this model can be resource
71 intensive if you have a large number of client
72 connections.
73 · prefork
75 The default. A process is started for each Samba
77 service, and a fixed number of worker processes are
78 started for those services that support it (currently
79 LDAP, NETLOGON, and KDC). The client connections are
80 then shared amongst the worker processes. Requests for
81 services not supporting prefork are handled by a single
82 process for that service.
83 The number of prefork worker processes started is
85 controlled by the smb.conf(5) parameter prefork
86 children, which defaults to 4.
87 --maximum-runtime=seconds
90 Set maximum runtime of the server process till autotermination in
91 seconds.
92 -b|--show-build
94 Print information about how Samba was built.
95 --usage
97 Display brief usage message.
98 --debug-stderr
100 Send debug output to STDERR.
101 --leak-report
103 Enable talloc leak reporting on exit.
104 --leak-report-full
106 Enable full talloc leak reporting on exit.
107 -d|--debuglevel=level
109 level is an integer from 0 to 10. The default value if this
110 parameter is not specified is 0.
111 The higher this value, the more detail will be logged to the log
113 files about the activities of the server. At level 0, only critical
114 errors and serious warnings will be logged. Level 1 is a reasonable
115 level for day-to-day running - it generates a small amount of
116 information about operations carried out.
117 Levels above 1 will generate considerable amounts of log data, and
119 should only be used when investigating a problem. Levels above 3
120 are designed for use only by developers and generate HUGE amounts
121 of log data, most of which is extremely cryptic.
122 Note that specifying this parameter here will override the log
124 level parameter in the smb.conf file.
125 -V|--version
127 Prints the program version number.
128 -s|--configfile=<configuration file>
130 The file specified contains the configuration details required by
131 the server. The information in this file includes server-specific
132 information such as what printcap file to use, as well as
133 descriptions of all the services that the server is to provide. See
134 smb.conf for more information. The default configuration file name
135 is determined at compile time.
136 -l|--log-basename=logdirectory
138 Base directory name for log/debug files. The extension ".progname"
139 will be appended (e.g. log.smbclient, log.smbd, etc...). The log
140 file is never removed by the client.
141 --option=<name>=<value>
143 Set the smb.conf(5) option "<name>" to value "<value>" from the
144 command line. This overrides compiled-in defaults and options read
145 from the configuration file.
146 -?|--help
148 Print a summary of command line options.
149 --usage
151 Display brief usage message.
152
154 /etc/rc
155 or whatever initialization script your system uses.
156 If running the server as a daemon at startup, this file will need
158 to contain an appropriate startup sequence for the server.
159 /etc/services
161 If running the server via the meta-daemon inetd, this file must
162 contain a mapping of service name (e.g., netbios-ssn) to service
163 port (e.g., 139) and protocol type (e.g., tcp).
164 /usr/local/samba/lib/smb.conf
166 This is the default location of the smb.conf(5) server
167 configuration file. Other common places that systems install this
168 file are /usr/samba/lib/smb.conf and /etc/samba/smb.conf.
169 This file describes all the services the server is to make
171 available to clients. See smb.conf(5) for more information.
172
174 Most diagnostics issued by the server are logged in a specified log
175 file. The log file name is specified at compile time, but may be
176 overridden on the command line.
177 The number and nature of diagnostics available depends on the debug
179 level used by the server. If you have problems, set the debug level to
180 3 and peruse the log files.
181 Most messages are reasonably self-explanatory. Unfortunately, at the
183 time this man page was created, there are too many diagnostics
184 available in the source code to warrant describing each and every
185 diagnostic. At this stage your best bet is still to grep the source
186 code and inspect the conditions that gave rise to the diagnostics you
187 are seeing.

199 The original Samba software and related utilities were created by
200 Andrew Tridgell. Samba is now developed by the Samba Team as an Open
201 Source project similar to the way the Linux kernel is developed.
