Hey LugNuts, A while back, I asked for input on NTP. I had to go away from that task, but it has now returned. At this point, I'm stuck and lost. So.... Is anyone synching their network using ntp? I have my ws synched, (our stratum 2?) I have a cron job entered that keeps it in sync. My problem is I can't get the other Lin boxes (stratum 3?) to sync from this one. I've tried using ntpdate -q to the ip and name of this box, to no avail. I recieve the following: ntpdate -q 192.168.10.55 server 192.168.10.55, stratum 0, offset 0.000000, delay 0.00000 23 Jan 12:58:48 ntpdate[3690]: no server suitable for synchronization found the ntp.conf file for our stratum 2 (name jupiter, IP 192.168.10.55) server 128.9.176.30 # US CA timekeeper.isi.edu server 192.5.41.40 # US DC tick.usno.navy.mil server 127.127.1.0 # local clock fudge 127.127.1.0 stratum 10 driftfile /etc/ntp/drift multicastclient # listen on default 224.0.1.1 broadcastdelay 0.008 authenticate no ntpdate -q 128.9.176.30 returns: server 128.9.176.30, stratum 1, offset 0.026086, delay 0.08362 23 Jan 13:00:30 ntpdate[16432]: adjust time server 128.9.176.30 offset 0.026086 sec which I believe is pretty good? offset of 0, is pretty close right? ntp.conf file for one of the proposed stratum 3's (name appserv, IP 192.168.10.33 server 192.168.10.55 # jupiter, our stratum 2 server 127.127.1.0 # local clock fudge 127.127.1.0 stratum 10 driftfile /etc/ntp/drift multicastclient # listen on default 224.0.1.1 broadcastdelay 0.008 authenticate no any idea why I'm getting the above error? any idea why it thinks jupiter is a stratum 0? if I use ntpdate -q 128.9.176.30 on appserv it returns: server 128.9.176.30, stratum 1, offset -211.413466, delay 0.08354 23 Jan 13:07:36 ntpdate[4314]: step time server 128.9.176.30 offset -211.413466 sec an offset of -211 is almost 4 minutes right? that's the difference between these two boxes... I've also tried using SNTS found here : http://www.redshift.com/~yramin/atp/snts/ I thought that one would be easy.... I have sntsd running on jupiter. I have snts running on appserv.... these don't appear to be working at all, as the boxes are still 4 minutes appart, and the SNTS stuff has been running for over 30 minutes. jupiter is RH 7.0 with ntp-4.0.99k-15 appserv is RH 7.1 with ntp-4.0.99k-15 I don't know what else I could tell you.... I know this is long, thanks for your time, E
