[CLUE-Tech] ntpdate broken in RedHat 7.2?

[Carl Gibbons]

Yes.  Nothing happened between RedHat 7.1 and 7.2 to break ntp.  It was my
fault; I had the firewall settings on "High."  When configuring ipchains
using the "lokkit" utility, I had to make sure "ntp:tcp" and "ntp:udp"
were allowed.  It ended up adding the following to my
/etc/sysconfig/ipchains:

-A input -s 0/0 -d 0/0 123 -p tcp -y -j ACCEPT
-A input -s 0/0 -d 0/0 123 -p udp   -j ACCEPT

I think there was a discussion about this on the clue-tech list a few
weeks ago, but I can't remember the thread subject.
