Description Ivo Clarysse 2001-05-08 14:18:32 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.2-2 i686; en-US; 0.8.1)
Gecko/20010422

Description of problem:
xntp3/ntp4 clients are not able to query the time from a RH71 system
running 'ntpd'.

How reproducible:
Always

Steps to Reproduce:
On the server:

1. 'rpm -Uvh ntp-4.0.99k-15.i386.rpm' 
2. Add appropriate 'server' lines in '/etc/ntp.conf', dependant on local
network config
3. '/etc/rc.d/init.d/ntp start'
4. Wait for ntpd to synchronize time from its' servers

From another client (tested: RH6.2 xntpd3, RH7.1 ntp4):

5. 'ntpdate <server></server>'  (with <server></server> the IP address of
the server
on which steps 1-4 were performed)
	

Actual Results:  ntpdate responds with: 'no server suitable for
synchronization found'

Expected Results:  Normally, the correct time should appear.

Additional info:

I tried this on 4 different machines, on my office network and my home
network, all with the same result.  If I download, compile and install
ntp-4.0.99k23.tar.gz on the server, it works OK (using identical config files).

Even though 'ntpdate <server></server>' fails, 'ntpq <server></server>' and
'ntpcd <server></server>' from the same client do work.

try the server with multicastclient disabled ... took me hours to find out :((

Comment 2 Ivo Clarysse 2001-05-11 17:13:57 UTC

OK, that works for me too.  I can live without multicastclient.
