備份配置檔案

# cp /etc/ntop.conf /etc/ntop.conf.old
			

/etc/sysconfig/iptables

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3000 -j ACCEPT
service iptables restart
			

啟動ntop

# /usr/bin/ntop -d -L -u ntop -P /var/ntop --use-syslog=daemon
or
# /usr/bin/ntop -d -L -u ntop -P /var/ntop --skip-version-check --use-syslog=daemon
			

/etc/init.d/ntop 腳本有bug無法啟動，需要如下修改

# vim /etc/init.d/ntop
start () {
    echo -n $"Starting $prog: "
    #daemon $prog -d -L @/etc/ntop.conf
    daemon $prog  @/etc/ntop.conf
