Levels above 3 are designed for use only by developers and generate HUGE amounts of log data, most of which is extremely cryptic\&. .sp Note that specifying this parameter here will override the \m[blue]\fBlog level\fR\m[] parameter in the /etc/samba/smb\&.conf file\&. .RE .PP \-\-debug\-stdout .RS 4 This will redirect debug output to STDOUT\&.
