The solution just says "Set your system time correctly. Use of Network Time Protocol to synchronize is recommended.
Is anybody familiar with how to do this? The solution wasn't very specific enough for my level of knowledge in Linux. I have 9.0 by the way. Thanks.
Kyle
Solved! Go to Solution.

Solutionthe Network time protocol (NTP) allows you to automatically adjust the time of your system vs. an (external) reference source. One provide in the US is the National Institute of Standards. Have a look at
http://www.boulder.nist.gov/timefreq/service/its.htm
Their SW is for Windows, you need the IP addresses of the servers only ;-)
You should be able to configure NTP from the RH management GUI (sorry, I use SuSE, so no specifics here).
The important thing is to add the servers of your choice to the ntp.conf file.

Re: System Time Clock Problem
I'm attaching one from an HP server, because its a good example, just change to a valid time source.
chkconfig 345 ntpd
service ntpd start
The first command(fuzzy, may have a syntax issue) will configure it, the service command will for sure run it.

Re: System Time Clock Problem
If the time shift accumulates depends on your connectivity. I use a Cable modem/router and the time on my systems stays pretty stable ;-)
Actually I do synch one server against an external source and then use this to synch my other systems against.

Re: System Time Clock Problem
The NTP port (123) is considered to be safe. If your firewall has just one port open, then the rest of the services can't be seen or reached from outside the firewall (assuming you have a good firewall and a good administrator). But good security demands that all ports be closed by default and then an explicit decision to run a service (open a port) made based on corporate guidelines. Most security problems come from inside the firewall.
