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. Does anyone has any idea of what might be wrong? or How to
configure a Red Hat Linux box as an NTP server?.........
Thanks,
Mario Siller.
The IP address of my NTP server is 20.0.0.1. 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
23 May 12:03:05 ntpdate[15169]: ntpdate 4.1.0 Wed Sep 5 06:54:31 EDT 2001

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
