* -i “eth0,eth1” : Specifies the network interface or interfaces to be used by ntop for network monitoring. Here you are monitoring eth0 and eth1.
* -d : Run ntop as a daemon.
* -L : Send all log messages to the system log (/var/log/messages) instead of screen.
* -u ntop : Start ntop as ntop user
* -P /usr/local/var/ntop : Specify where ntop stores database files. You may need to backup database as part of your disaster recovery program.
* –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.
* –use-syslog=daemon : Use syslog daemon.
