Hi,
I'm trying to configure NTP on several Red Hat Linux boxes without any
success. I'm including some information about the configurations I'm
working on.
How to configure a Red Hat Linux box as an NTP server?.........
Does anyone has any idea of what might be wrong?....
Thanks.
The IP address of my NTP server is 20.0.0.1. The configuration I have on the
server ntp.conf file is:
server 127.127.1.0
fudge 127.127.1.0 stratum 0
authenticate no
The configuration I have on the clients ntp.conf file is:
server 20.0.0.1
authenticate no
On the other hand the ntpd daemon on the server seem to be working ok. When
I do a ntptrace on the server this is what I get:
----------------------------------------------------------------------------
----------------------------------------------------------------------------
--------------------
[root@localhost root]# ntptrace
localhost.localdomain: stratum 1, offset 0.000074, synch distance 0.01485,
refid 'LCL'
[root@localhost root]#
----------------------------------------------------------------------------
----------------------------------------------------------------------------
--------------------
When I run a ntpdate from any client this is what I get:
----------------------------------------------------------------------------
----------------------------------------------------------------------------
--------------------
[root@localhost log]# ntpdate -b -v -d -u 20.0.0.1

Finally if I start up the ntpd daemon on any client and run the commands
"ech rv | ntp" and ntpq -p this is what I get:
----------------------------------------------------------------------------
----------------------------------------------------------------------------

[root@localhost log]# echo rv | ntpq
