Я использую AWS и нахожусь на сервере EC2 ...

[dalvarado@mymachine ~]$ uname -a
Linux mydomain.org 3.14.33-26.47.amzn1.x86_64 #1 SMP Wed Feb 11 22:39:25 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Мои часы отключены на минуту ро, так что, несмотря на то, что у меня уже установлен и работает NTPD

[dalvarado@mymachine ~]$ sudo service ntpd status
ntpd (pid  22963) is running...

Казалось бы, пакеты ntp заблокированы или есть какая-то другая проблема, потому что я получаю эту ошибку ...

[dalvarado@mymachine ~]$ sudo ntpdate pool.ntp.org
 2 Apr 16:43:50 ntpdate[23748]: no server suitable for synchronization found

Кто-нибудь знает с AWS, есть ли другой сервер, с которым я должен связаться для получения информации о NTP, или есть ли другие дополнительные конфигурации, которые мне нужны?

Спасибо, Дэйв
