hi,

find one ntp server on the internet and setup the ntp with sam. Sam will do all the work for U.

check it with:
ntpq -p

ok.
on serverb go into sam -> time -> NTP Network Time Source and remove any entry and stop the NTP service.
From actions (in the top) add a server servera and then start the NTP service again.

BR,
Jannik

Hi,

I did the similar thing before, I don't need to use ntp to set my server to be exactly as atomic clock, I just need to sync the clock on 2 servers for application reasons. what I did was:

1, use "date" command to set the time of the 2 servers to be as sync as possible (within 30 seconds offset, otherwise, there maybe problems with ntpdate)

2, run "ntpdate -b serverA" from server B to initially sync the 2 servers. (note that xntpd was not started yet then)

3, on serverA (ntp server) /etc/ntp.conf file set "server 127.127.1.1" and start xntpd, it means it will use its own clock as time source.

4, on serverB (ntp client) /etc/ntp.conf file
set "server serverA_IP" and "driftfile /var/adm/ntp.drift" then start xntpd.

that's it.

thanks,
Gary
