    Nah, you'll warm up to it.  In fact, some of what I've learned has
been in saying "What the heck is that?!!?!" from things I saw in
LogWatch. It's a handy tool.

    This (I'm fudging) has to do with not having _unique_ certificates
set up properly on your server.  There are howtos for this on the net. 
I'm having to get mine set up, too....I don't like people using POP/IMAP
on my site without their passwords being scrambled.  They *might* not be
necessary if cleartext passwords are no problem for you. (The howto will
tell the tale; see google.)

    Not a problem; modern Linux appears to want to start IP version 4
AND 6 versions of things. I'm thinking they have a plan to move us that
way, soon.  This one isn't a problem.

    This is a hard drive usage list.

    /dev/hda<partition number> is a partition on the primary master,
hdb, the secondary.

    /dev/hdc<partition number> is a partition on the secondary master,
and hdd, the secondary.  Some motherboards have more, but this is
standard.

    /dev/shm is kinda new to me, but it vaguely relates to 'shared
memory' and I *think* deals with swap space, or a RAM-based temporary
storage (think: /tmp directory).  I'm no expert on this.

    Some of these are already discussed in this list; most you'll just
have to learn-as-you-go.  Don't worry- we're here to help, as long as
you at least _try_ to research it on your own.

    Good luck!
