Just in case you run a legitimate open NTP server, this iptable stanza helps immensely: ## rate limit ntp $IPTABLES -N NTP $IPTABLES -N BLACKHOLE $IPTABLES -A BLACKHOLE -m recent --set --name ntpv4blackhole --rsource $IPTABLES -A BLACKHOLE -j DROP $IPTABLES -A NTP -m recent --update --seconds 5 --

I don't have the quantity you need, but this reminded me that I'm in need of a reliable supplier of CWDM 40KM XFP 10GbE optics. Specifically 1310nm, but I'll need other wavelengths soon. These things seem to be manufactured by elves. I can't find a reliable supplier anywhere. Can anyone help?
