I'm running ntpd on our RedHat Linux firewall.  It seems to be working
OK according to the logs.  Plus I can ntpq it 'remotely' from another
machine in the LAN.

[machine-b]# ntpq -p machine-a
     remote           refid      st t when poll reach   delay   offset
jitter
==============================================================================
+otc1.psu.edu    .WWV.            1 u   57   64   77  111.122  -23.150
 3.132
-ntp-1.cns.vt.ed timelord.cns.vt  2 u    1   64  177   97.639    6.030

+clock1.redhat.c .CDMA.           1 u   61   64   77   83.241   -3.625

*clock2.redhat.c .CDMA.           1 u    -   64  177  102.931   -3.521
 7.287

However, when I run ntpq on the firewall it times-out!

[machine-a]# ntpq -p
127.0.0.1: timed out, nothing received
***Request timed out

ntp.conf looks like this (minus some of the other servers for brevity)
------ BEGIN ntp.conf -----
restrict default ignore
restrict 192.168.0.1 mask 255.255.255.255 nomodify notrap
restrict 127.0.0.1
restrict 192.168.0.0 mask 255.255.255.0 notrust nomodify notrap

# clock.redhat.com
restrict 66.187.233.4 mask 255.255.255.255 nomodify notrap noquery
server 66.187.233.4

fudge	127.127.1.0 stratum 10
driftfile /etc/ntp/drift
broadcastdelay	0.008
authenticate no
------ END ntp.conf -----

That is annoying.  Anyone know why I can't use ntpq on the firewall?

[machine-a]$ rpm -q ntp
ntp-4.1.1-1
[machine-a]$ rpm -q redhat-release
redhat-release-7.2-1

BTW I even tried the following 2-line ntp.conf and got the same
results:
server 66.187.233.4
driftfile /etc/ntp/drift

TIA
