Thanks! It put me on track for arpalert. I installed it and am puzzling 
out how to work with it...I thought there's a script in 
/usr/share/doc/exampled/scripts/contrib for adding discovered MACs into 
the allow list, but it doesn't seem to be working as advertised (already 
changed path variables in the script for what's set up in Ubuntu).

Once I can figure out how to get the allow list working and then figure 
out how to get it to mail me (I added the mail program using mailutils) 
then I should be set to go...I think...
