	Problem is, BIND 8.2.2 has a root compromise that means anyone in 
the world can own your machine in nanoseconds.  There's even a Linux 
"worm" going around that will automatically compromise any vulnerable 
machine it encounters.  See 
<> and 
<>.  Note that the latter is 
dated January 29, 2001.

	Obviously, you're one of the sites that would be compromised by 
the Linux Lion Worm (and probably already has been), since you didn't 
apply the update to your machines when the problem was first 
published in January.

	I still suggest getting at least 8.2.3-REL and installing it on 
your machines, if not trying the latest release candidate for 9.1.1 
(currently at 9.1.1rc7).  Ideally, you'd also download the source 
code and compile it for yourself, because you can't be sure that the 
binary RPMs you download have not themselves been trojaned.
