-u Direct ntpdate to use an unprivileged port for outgoing packets.
This is most useful when behind a firewall that blocks incoming
traffic to privileged ports, and you want to synchronise with
hosts beyond the firewall. Note that the -d option always uses
unprivileged ports.
So ntpdate does not try and use 123 -- which is in use by ntpd.
Does:
sudo netstat -a -n -p | grep ntpd
show something like:
udp 0 0 192.168.0.xx:123 0.0.0.0:* 1693/ntpd
udp 0 0 127.0.0.1:123 0.0.0.0:* 1693/ntpd
udp 0 0 0.0.0.0:123 0.0.0.0:* 1693/ntpd
udp6 0 0 fe80::222:68ff:fe36:123 :::* 1693/ntpd
udp6 0 0 ::1:123 :::* 1693/ntpd
udp6 0 0 :::123 :::* 1693/ntpd
unix 2 [ ] DGRAM 6635 1693/ntpd
