<!--[if !supportLists]-->§  <!--[endif]-->-P /usr/local/var/ntop : Specify where ntop stores database files. You may need to backup database as part of your disaster recovery program.

<!--[if !supportLists]-->§  <!--[endif]-->--skip-version-check : By default, ntop accesses a remote file to periodically check if the most current version is running. This option disables that check.

<!--[if !supportLists]-->§  <!--[endif]-->--use-syslog=daemon : Use syslog daemon.
