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.
There are no patches. You need to manually harden ntp.conf. It is impossible to implement via patch.
See http://blog.cloudflare.com/technical-details-behind-a-400gbps-ntp-amplificat... and the linked articles.
