local0.debug /var/log/mtaped.log
or
user.debug /var/log/mtaped.log
if your system does not support the facility local0 (e.g. Ultrix)
Send the signal SIGHUP to the syslogd daemon to force it to reread its configuration file, therefore sending debug messages and others of higher priority from local0 daemon (in.mtaped) to the log-file.
# ps -ax 1#1 grep syslogd 1#1 grep -v grep
(this will tell you the PID number for the syslogd proccess)
# kill -HUP syslogdPID
You can read the messages coming in the log-file by:
# tail -f /var/log/mtaped.log
