Time Sync - AIX

Hi All- We are running AIX 4.2.1 on a stand-alone F40 machine. I would like to have the clock automatically updated using the atomic clock in Boulder, Colorado or another reliable time server. Is the operating system equipped to handle this on it's own, and if so how does one set it up? Or, is there a program available to accomplish this? Thanks in advance, Dave Mason...

    First, edit /etc/ntp.conf last lines should appear like so;

    # Default NTP configuration file.
    #
    # Broadcast client, no authentication.
    #
    #broadcastclient
    server server.ofyourchoice.com
    driftfile /etc/ntp.drift
    tracefile /etc/ntp.trace

    Next Uncomment line in rc.tcpip so that service always starts ;

    # Start up Network Time Protocol (NTP) daemon
    # start /usr/sbin/xntpd "$src_running" uncomment this linwe

    =IF is down set time and start service manually;

    # lssrc -s xntpd
    Subsystem Group PID Status
    xntpd tcpip inoperative

    Service is not running, so start it, or refresh it if you made changes
    to /etc/ntp.conf

    # startsrc -s xntpd
    0513-059 The xntpd Subsystem has been started. Subsystem PID is 14420.

    Before you start the xntpd service, run ntpdate by hand. The daemon
    won't perform any adjustments if the system time is too far out of
    sync with the time source ... IIRC, 5 minutes off is the magic value.

    Well, a quick 'man xntpd' says my memory ain't worth sh&t. The magic
    value is 1000 seconds :-)

    Thanks for your help. My clock is now very accurate. But, another question:
    How often does the daemon sync with the time server?

    You may want to run the xntpd daemon. man xntpd will get you started.
