NTP Configuration.

[Kaydo]

Howdy Everyone,

I'm new to RHREL 5.4 and am trying to setup an NTP server on my network.
I've done lots of googling and man page reading, but I'm still a bit
confused on a few things.  

1.  Do I need to have a step-tickers file?  If so, why? 
 
2.  When I configure my client RHEL machines to access my NTP server, is it
better to run ntpd or use ntpdate in a cron job?  I've seen articles with
people using both methods so I'm not sure which is better.

3.  My ntp.conf file has a line that says "restrict default kod nomodify
notrap no peer noquery".  Do I still need to have separate restrict lines
for each of my server entries or will that one line cover all of them?  Eg.
restrict ntp.server.org   mask 255.255.255.255 nomodify notrap noquery 

Thanks guys.
