Check that you have the ntpd package installed on your RedHat Linux system. Look for it with a command such as: <root,32># rpm -qa | grep ntp This should return the full name of the ntp (network time protocol) package, if it's installed. If you have the package installed, then start ntpd by typing: <root,33># /etc/init.d/ntpd start My RedHat 7.3 system returns this list. ntp-4.1.1-1 chkfontpath-1.9.5-2

You may need to configure the file /etc/ntp.conf to point
to a time server near you.  You may need to add a line
to this file which reads
    server  time.nist.gov           # NIST clock
where time.nist.gov would be replaced by the name of a time
server.  If you are lucky, you may be able to use time.nist.gov.
Whatever, the time server you name MUST be running an ntpd process.

To make ntpd start when you boot the Linux computer,
you may need to configure it in the /etc/rc.d/ directories.
You may find this command useful to make this happen:
   <root,34># chkconfig --level 345 ntpd on
This will start ntpd whenever the system transitions
into run levels 3, 4, or 5.

If you do not have an ntpd package installed,
either look on the RedHat 6.2 installation CD in the RedHat/RPMs
directory or go to www.rpmfind.org and download one from there.

Dear Sir:

I have encount a problem about the setting of correct date of IOC.

Host: Intel PentiumII 400 PC, Redhat6.2

It seems the IOC can't get the time from Linux Host. what's steps should done to make it correct? Need I set some environment variables?

The time on IOC now is:
->date
Dec 21, 2028 22:18:57.006969513

while the host time is :
$ date
Mon Jul 22 18:57:21 CST 2002

I don't know where did IOC get the date value.

Any suggestion is welcomed.
