Well, I now plan to go to 2.7 with Redhat 7.2. We'll see what happens
there. Have you tried it yet?

And that's what I am doing, but 2.7 sounds like a major change...

Yeah, I got a scolding from someone else about this. I may take you up on
that offer! :-)

I found that out on day one, and had it all fixed on day 2. Xinetd is
really picky!!!
