Unless DARPA has changed its policy (which I doubt) its network is for
use by DARPA work only.  If you have gateways into Internet then it is
your job to see that non authorized persons do not have access.  DARPA
has pulled the plug on sites in the past (I can think of one) that
violate its policies.

Now being realistic only a fraction of network traffic could be
considered valid.  There are many researchers who use utilities like
mail and FTP and this greatly aids the research community as a whole.
There is also a good deal of traffic in human interest mailing lists
and there are some sites that serve as file servers for micro related
files.  For now DARPA looks the other way on these uses of its network.

If you are worried about your undergraduates then you should restrict
read assess to FTP, telnet, rlogin, etc.  I believe this is done at
our site.  I am sure Unix wizards could come up with more imaginitive
ways.  At our site we have all students sign a sheet that gives our
definition of malicious hacking and describes penalties that are
levied (such as loss of account) if our rules are not followed.  If
the student does not sign the sheet he does not get an account.

You have to be careful if you decide to restrict some things and not
others.  I do remember getting an account on a site for the first time
and finding that I didn't have access to telnet.  I used FTP to get a
telnet from a "public access" site and used it until root gave me the
right privs.
