If I want to use NTP to sync to a time server does my
machine have to
open port 123 UDP. I don't want to be a NTP server, I just
want to be
the client that polls a server. I know I can use iptables
to do
something like
$IPTABLES -A INPUT -j ACCEPT -p tcp -s 66.187.224.4 --dport
123
But I would like to completely close the port if possible.
Can this be done?
Thanks,
Nick
