Nevermind.  rpc.statd was running on port 1008 becuase I initially
thought I would most likely wind up using this box as a NFS server.  I
didn't, but forgot to shut down nfs services.

Digging around, I found it, and shut it down.  Whew.

Now chkrootkit doesn't report anything out of the ordinary.  

Prelude's log and my security.log don't show anything out of the
ordinary.

I think I'm okay.  As well as a little better informed than I was at the
start of the day, which means today has been a success.  The rest is
smooth sailing!  Maybe I'll overacheive and try to learn some more
things today...
