ntpd not adjusting the time

Question

In my Ubuntu 14.10 ntp doesn't seem to work. If I call:

ntpd -g -q

This is the output in syslog:

Dec 12 20:33:26 nebelhaufen ntpd[28659]: ntpd [email protected] Wed Oct  9 18:56:59 UTC 2013 (1)

How can I set the time on Ubuntu via ntpd?

EDIT: ntpdate -q ntp.ubuntu.com works fine, but I read, that ntpdate is deprecated?

Answer 1

The problem is you are trying to run a network daemon, and this line is the main problem:

unable to bind to wildcard address 0.0.0.0 - another process may be running - EXITING

First suspect is if you are root or not; low ports are not for non-root users. The second is it seems also ntpdate is running as damon after install: "ntpd unable to bind to wildcard address 0.0.0.0 - another process may be running"

If your system is already running ntpd, ps ax|grep ntp shows that? If so, stop it with

sudo service ntp stop

before running

ntpd -g -q

Answer 2

Run netstat -pnl | grep 123 to identify the process that is listening on port 123, kill it, then restart ntp.
