Hello- I am James Riordan and I am ostensibly a graduate student in mathematics at the University of Minnesota. I somehow find myself in the position of trying to improve our networks security. We do not have the option of setting up a firewall so I am trying to set up one "safe" machine from which the others can be monitored. regards, -- james riordan@geom.umn.edu http://www.math.umn.edu/~riordan
