    Anyone know if cPanel uses NTP on a VPS instal with Centos 6? I heard about an NTP vulnerability that enables DDoS attacks and want to make sure I can patch anything needed.

    ntp is provided as a system RPM from CentOS.

    If other servers do not need to sync time from your server, simply close tcp and udp port 123 for inbound traffic in your firewall. This is what I do on my own server.

    OPEN NTP Project has more information.

    Hello :)

    Yes, as mentioned in the previous post, NTP is installed by default if you are using CentOS. It's not required, but you can follow the instructions from the previous post to prevent inbound traffic to that port.

    Thank you.
