I want to configure NTP on this box, i.e. the Cobalt Qube as its losing time. Badly.
Dhis is now done, I have a very simple ntp.conf file and am using DNS hostnames. This is not advisable under Linux because you must have a valid DNS service available when the daemon seeks to resolve the addresses. It might be possible to resolve the dns names vis the /etc/hosts file. The Howto article below is quite good.
The test should be ntpq -p to see if the deamon is working Ok, I don’t think the Cobalt ntpd script does this; it browses the process table.
- check ntp isn’t running
- Add the server lines to /etc/ntp.conf, you really need two. Use time servers from organisations that permit or don’t care that one’s taking a feed.
- Enable port 123/udp on the firewall
- Start the daemon
- Test the service using ntpq, can you see all the configured servers
- If the drift is significant from the time server, then take the service down and then use ntpdate -u to set the clock
The Linux chkconfig utility is set up for the rc script and I shall therefore invoke it using chkconfig -add.
I have found the following links
I returned to this in 2011, and found http://www.pool.ntp.org/en/use.html. It’s all got a lot easier.
