I want ntpdate, and don't really care about ntpd. I need an ntp server running on one node, and the other nodes connect to the first node with ntpdate like this:
#!/bin/bash SERVER=ntpserver1 RATE=5 while [ 1 ]; do ntpdate -b $SERVER ntpdate -b $SERVER ntpdate -b $SERVER sleep $RATE done So I think what I would like to do is install an NTP server on one node, verify that it works ;^) and have the others keep in synch with the script. There are no firewalls between the nodes. There is a firewall to the outside world but that is not in my control. --- On Thu, 9/16/10, Rob <[email protected]> wrote: > From: Rob <[email protected]> > Subject: Re: [ntp:questions] Why does ntp keep changing my conf file? > To: [email protected] > Date: Thursday, September 16, 2010, 1:04 PM > Daniel Havey <[email protected]> > wrote: > > Did you mean between my testbed and > ntp.aero.org/dns.aero.org (the servers in my ntp.conf > file)?
