Hallo,
analyzing my network traffic i saw lot's of high volume connections from
my ntpd to game servers..
googling arround (https://www.google.com/search?q=ntp+xbox+gameserver) i
read about DDoS attacks using ntp.
How to avoid my ntpd being used for that?
installed ntp-4.2.6p5-9.3.1.x86_64
Thanks for help


You need to apply the relevant security updates.

See http://blog.cloudflare.com/technical-details-behind-a-400gbps-ntp-amplification-ddos-attack and the linked articles.
