DESCRIPTION

This program is part of the Samba(7) suite.

smbd is the server daemon that provides filesharing and printing services to Windows clients. The server provides filespace and printer services to clients using the SMB (or CIFS) protocol. This is compatible with the LanManager protocol, and can service LanManager clients. These include MSCLIENT 3.0 for DOS, Windows for Workgroups, Windows 95/98/ME, Windows NT, Windows 2000, - OS/2, DAVE for Macintosh, and smbfs for Linux.

An extensive description of the services that the + OS/2, DAVE for Macintosh, and smbfs 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 (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.

A session is created whenever a client requests one. Each client gets a copy of the server for each session. This copy then services all connections made by the client during that session. When all connections from its client are closed, - the copy of the server for that client terminates.

The configuration file, and any files that it includes, + the copy of the server for that client terminates.

The configuration file, and any files that it includes, are automatically reloaded every minute, if they change. You can force a reload by sending a SIGHUP to the server. Reloading the configuration file will not affect connections to any service that is already established. Either the user will have to - disconnect from the service, or smbd killed and restarted.

debuglevel is an integer +compile time.

-d|--debug=debuglevel

debuglevel is an integer from 0 to 10. The default value if this parameter is -not specified is zero.

The higher this value, the more detail will be +not specified is zero.

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 +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 extremely cryptic.

Note that specifying this parameter here will -override the log -level parameter in the smb.conf(5) file.

-l|--logfile=logbasename

File name for log/debug files. The extension -".client" will be appended. The log file is -never removed by the client.

-h|--help

Prints information about how - Samba was built.

-l <log directory>

If specified, - log directory - specifies a log directory into which the "log.smbd" log +data, most of which is extremely cryptic.

-l <log directory>

If specified, + log directory + specifies a log directory into which the "log.smbd" log file will be created for informational and debug messages from the running server. The log file generated is never removed by the server although - its size may be controlled by the max log size - option in the smb.conf(5) file.

This number is the port number that will be + specified is 139.

This number is the port number that will be used when making connections to the server from client software. The standard (well-known) port number for the SMB over TCP is 139, hence the default.

In order for the server to be useful by most clients, should you configure it on a port other than 139, you will require port redirection services on port 139, details of which are outlined in rfc1002.txt - section 4.3.5.
