I observed this type of probing when I lived on campus a year ago during
grad school at the University of Texas at Austin.  This link
<http://www3.utsystem.edu/itmc/IT100699.htm> has meeting minutes detailing
Bill Bard (Top UT Network guy) saying periodic scanning s a good thing
(tm).

On the policy side, check out UT ResNet acceptable useage
policies: http://resnet.utexas.edu/policy/policy.html.
