The time will be set correctly. This is the way they recommend utilizing security with Samba. But indeed, if your ISP blocks incoming NTP, they should provide an NTP server on their network. –Gilles Mar 10 '14 at 19:09 I had already added these rules With the previous package and that configuration the IPv6 access wasn't restricted at all.

I now realize that the clock should be set to the correct time using ntpdate (which I never had a problem getting to work) and then using ntpd to keep it I have done that with examples of both secure and insecure config files.

Letting ntp run against your own local clock gives you a false sense of having a "backup" source. navigate here The fact is that security starts by making things ultra secure first, then reducing security to allow certain things in.

i have a master's degree in technical writing, and i still don't understand it. Is this referring to adding the words "stratum 2" for each server you have listed (assuming they are stratum 2 servers)? Why would two species of predator with the same prey cooperate? They are 100% on the same subnet and the IP addresses are right as I can ssh no problem.

You need at least one flag to convert the rule from its naked state of ALLOW into a more seemly state of DENY. That's a good thing. Please visit this page to clear all LQ-related cookies. Try Debian's, my (working) ntp.conf is here. –terdon♦ Mar 9 '14 at 17:17 Yes, it's ntp.conf.
