If you are running the ntpd ... this is the list we use in redhat's /etc/ntp.conf. I've not checked up on these in at least a year. Some are commented out, don't recall why. The "stratum 1 systems" listed below should not be used, they are unavailable unless you are a "stratum 2" server that has been added to their access lists. - tom e. # from http://www.eecis.udel.edu/~mills/ntp/clock2.htm # stratum 2 systems: # Western USA (MAE-West attached) server nic.scruz.net # UCSD Academic Computing Services/Network Operations, San Diego, CA server ntp.ucsd.edu # UNLV College of Engineering, Las Vegas, NV server tick.cs.unlv.edu server tock.cs.unlv.edu # U. of Nevada, Las Vegas server cuckoo.nevada.edu # Washington Univ. server clock.tricity.wsu.edu # Norman, OK server constellation.ecn.uoknor.edu # Penn State Univ. #server server clock.psu.edu # Purdue University Engineering Computer Network, West Lafayette, IN #server gilbreth.ecn.purdue.edu # Purdue University Engineering Computer Network, West Lafayette, IN #server harbor.ecn.purdue.edu # Cox School of Business, Southern Methodist University, Dallas, TX #server ntp.cox.smu.edu # Center for Seismic Studies, Arlington, VA Geographic Coordinates: 38:53:50N, 77:04:34W #server ntp.cmr.gov # First National Bank of Hughes Springs, TX #server ntp.fnbhs.com # Baylor College of Medicine, Houston, Tx #server ntp.tmc.edu # stratum 1 systems: #server ntp2.usno.navy.mil prefer #server tock.usno.navy.mil # server clock.llnl.gov prefer # server navobs2.usnogps.navy.mil # server clock.osf.org ------------------------------------------------------------ On Sun, 13 Oct 2002, Scott wrote: > Here is a script that I use on my system to query ntp servers and update > the system clock. > > > #!/bin/sh > echo "Current date and time: `date`" > timehosts=ntp2.usno.navy.mil > if /usr/sbin/ntpdate -ub $timehosts > /dev/null; then > /sbin/hwclock --systohc > echo "Updated date and time: `date`" > fi > > > Since I run this via cron, I have it print the time before and after the > update. > > scott > > > On Sun, 13 Oct 2002, Kevin Brown wrote: > > > Bah.
