IP address of the server
level is an integer from 0 to 10. The default value if this
parameter is not specified is 1.
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 extremely cryptic.
Note that specifying this parameter here will override the log
level parameter in the smb.conf file.
Prints the program version number.
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 compile time.
Base directory name for log/debug files. The extension “.progname”
will be appended (e.g. log.smbclient, log.smbd, etc…). The log
file is never removed by the client.
Set the smb.conf(5) option “
command line. This overrides compiled-in defaults and options read
from the configuration file.
