發現機器時間跟標準時間差了 40 秒左右，結果有些服務因為會看雙方時間，就不讓我跑… XDDD 找問題找了半天，發現開機後 ntpdate 會回報找不到伺服器，看起來是網路根本就還沒通就跑起來了： Jan 25 13:10:30 home ntpdate[757]: name server cannot be used: Temporary failure in name resolution (-3) Jan 25 13:10:30 home ntpdate[1171]: name server cannot be used: Temporary failure in name resolution (-3) Jan 25 13:10:30 home ntpdate[1347]: name server cannot be used: Temporary failure in name…

How to use ntpdate behind a proxy?
Is it possible to use ntpdate behind a HTTP proxy with authentication? In case it is not possible, are there any good alternatives?
Answer [by KCotreau]: How to use ntpdate behind a proxy?
If it is purely an HTTP proxy, it is using port 80, so the basic answer is no to that specifically. NTP uses UDP port 123. If it is a more generic proxy server, serving all…

ntpdate and ntpd failing to sync clock on Linux
I have a strange problem with one of my servers. ntpd and ntpdate fail to work, but debugging shows no errors at all. At first I thought maybe a local or network firewall was blocking UDP port 123, but that is not the case- this server can talk UDP port 123 (the ntp protocol) to the Internet and get answers.
Let me demonstrate the issue.

What are the pros and cons between these two ways to synchronize your server?
It seems to me that your server would probably not drift more than 1 second every day, so ntpdate on a crontab would be ok. But I heard you could use redundant NTP servers here
http://www.pool.ntp.org/en/use.html
in order to maintain synchronized time in case of failure.
