Ss Sun04pm 0:12.45 /usr/sbin/ntpd -p /var/run/ntpd.pid I'd suggest killing both of those ntpd processes and starting it up again. Actually, before you restarting, try manually synchronising with one of your servers, eg: # ntpdate subitaneous.cpsc.ucalgary.ca That will at least tell you that you can talk NTP with this server. I assume all the servers in your ntp.conf are public ones that your host is allowed to use? The firewall rules look OK, although you might want to add 'log' to your default block rule while diagnosing a problem like this, so you'll be told if ipf is blocking any of the packets you're interested in.
