Good info, but does ntpq use different ports than ntpdate? After all, ntpdate works, but ntpq does not.
It's easy to check. Open two terminal windows on your client. In the first, run # tcpdump -nn host 213.239.194.210 (213.239.194.210 is the address of a public ntp server, but you can substitute it with one of your own) In the second run # ntpdate -q 213.239.194.210 On my laptop, it results in: 23:20:10.906836 IP 182.188.1.103.32890 > 213.239.194.210.123: NTPv4, Client, length 48 23:20:10.938987 IP 213.239.194.210.123 > 182.188.1.103.32890: NTPv4, Server, length 48 23:20:10.939104 IP 182.188.1.103.32890 > 213.239.194.210.123: NTPv4, Client, length 48 23:20:10.971364 IP 213.239.194.210.123 > 182.188.1.103.32890: NTPv4, Server, length 48 23:20:10.971444 IP 182.188.1.103.32890 > 213.239.194.210.123: NTPv4, Client, length 48 23:20:11.002340 IP 213.239.194.210.123 > 182.188.1.103.32890: NTPv4, Server, length 48 23:20:11.002434 IP 182.188.1.103.32890 > 213.239.194.210.123: NTPv4, Client, length 48 23:20:11.037272 IP 213.239.194.210.123 > 182.188.1.103.32890: NTPv4, Server, length 48 So, my laptop uses a high port value, the server uses 123.
