openntpd config question - security in /etc/ntpd.conf

graysky · 2009-08-07 22:41:01

I read the NTP wiki page and installed openntpd. It wasn't clear to me from the page if the default /etc/ntpd.conf was secure or if securing it requires additional lines. Right now I'm using the default /etc/ntpd.conf which only contains a 'servers' line. Are there any recommended lines to add security to this daemon or is this one-line config file sufficient security-wise?

Thanks!

Hello graysky!

For what kind of security do you think ?

If I understand correctly: A) the security section on that page is for ntp and not openntp and B) It's only a security issue if you're using it to act as a server and not just as a client (the default config is for it to just be a client, so it shouldn't be a hazard)

It can be really off-topic, but ntp security model:

A) Right, I made a slight modification to the wiki page
B) Okay, thanks for the clarification
