NTP and Firewall help needed.

I'm trying to set up NTP to keep the clock adjusted on my PC workstation
running under RedHat 9. (There's no local network involved.)

I used the RH Time/Date tool to configure 'ntpd', but that apparently
doesn't set up the appropriate entry in iptables, and gnome-lokkit doesn't
seem to have the capability to do this.

I've tried 'firestarter' to set up iptables, and that works. However I'm
constantly hammered with portscans or other drivel from the 'net, all of
which firestarter allows to be recorded in /var/log/messages to the extent
of 2-3 MB per day. Although 'logrotate' keeps the size of the messages
within reasonable bounds, this pretty much makes /var/log/messages useless.

I've been reluctant to manually fiddle with iptables for fear of seriously
compromising my PC's security.

Expert advice will be appreciated.

Regards,
Charles Sullivan
