ntp server: mulitiple interfaces

[Joel Hammer]

I think  I have solved the problem but as usual I am not sure what it was.

There were three anomalies:

1. The output of peer with ntpq had no "tattletails" by the names of the servers.
eg:
     remote           refid      st t when poll reach   delay   offset jitter
==============================================================================
hammer2.jhammer tock.usno.navy.  2 u   38   64  377    0.871  -68.400 9.995

This is supposed to mean that the server is not being used.

2. When I ran "ntpdate", I got no available servers.
Running "ntpdate hammer2" gave me a time and an offset, but it wouldn't
synchronize.

3. When I ran ntpdate localclient, I got connection refused.

Well, to make a long story short, I removed the firewall on the local
client, opened up an explicit hole in the firewall on the server, changed
the client's timezone from West Coast to East Coast, and started up ntpd
on the localclient (yes, I had turned it off).

Now, nptq gives :
     remote           refid      st t when poll reach   delay   offset jitter
==============================================================================
*hammer2.jhammer tock.usno.navy.  2 u   24   64  377    0.865  -57.682 5.495

So, things seem to be working.
