Service DNS and NTP from FC6

[Bledsoe, Howard W. CIV (CNRNW)]

 John:

	It had not occurred to me to open UDP on those ports also -- but
that did the trick.  You sir, are a gentleman, a scholar, and
undoubtedly a fine judge of good whiskey.

            Tnx, Howard

Just one other thing.  Make sure that you told the firewall to open UDP
(not TCP) port 123 for ntp.  Again, I don't run DNS, but I seem to
recall that it wants both TCP and UDP opened for port 53.
