NTP Server

Here are the steps.
1- Download the ntp-4.0*.tar.gz from www.ntp.org
2- Uncompress it and untar it to /usr/local/src
3- do a ./configure;make;make install;
This will install the ntp deamon on your server.
4- Go back to www.ntp.org and search for a public time server near you, that allows you to pull time from.
5- Edit the /etc/ntp.conf and add at least 2 servers into it.
6- Start the ntpd deamon.

The included manual is clear enough so you could do all by yourself.
Have fun.

install xntpd.rpm, then configure your machine as time server: (minimum configuration in /etc/ntp.conf:
server 127.127.1.0
fudge 127.127.1.0 stratrum 0

time is not being synchronised from another time server, read the manual to learn how to do so, it's easy)
start the daemon ( /etc/rc.d/init.d/xntpd start )
check with ntptrace
