Re: ntp daemon.

you don't have to open port on your router because if you reach internet (without firewall on your system) every ntp packet to get to the right place. 

now should run
stop ntpd
ntpdate <something server>
and check
ntpq -p
and
start ntpd again.

Now, it has to work.

I have installed ntp server on my debian box.
I am trying to sync with a public external time server.
I have found a couple on the internet - but none seem to want to sync
with me or my ntp daemon does not want to do it.

I have entered the following in my /etc/ntp.conf file:

server 0.us.pool.ntp.org
server 1.us.pool.ntp.org
server 2.us.pool.ntp.org
server 3.us.pool.ntp.org

I ran ntpdate and I get this error message -
18 Jan 12:43:23 ntpdate[26430]: no servers can be used, exiting


ntpdate should not / cannot be used while ntpd is running.  Make sure
that ntpd is running and then run:

ntpq -p

That'll show you what ntp servers you are communicating with.

You do not need to open any inbound ports on your firewall in order for
ntpd to run.  Also, the default debian ntp.conf file works if you are
just trying to keep your own time accurate, and not trying to act as an
ntp server for other machines.
