Thanks, Richard. I've not met domestic routers which require specific
configuration for NTP packets, but perhaps I've just been lucky. Would
what you describe explain why ntpdate -q <remote> works, but nptdate
<remote> responds with "no server suitable for synchronization found"?
[By works, I mean he gets a response like:
server 220.127.116.11, stratum 2, offset 12.016615, delay 0.05682
4 Apr 08:49:58 ntpdate: step time server 18.104.22.168 offset
