I'm wearing several hats at the moment. I am working in Systems administration and WWW project at the University of Melbourne; I have recently installed a firewall system for a hospital in Melbourne, where I was SysAdmin. It was my first, so I am keeping a close eye on it and trying to be careful about detecting intrusion, especially on the bastion. I am also manager of an Internet provider company in Melbourne, so that's another place I have to be careful with. We decided only to provide SLIP access, and not Unix shell access, purely to reduce our security headaches. Danny
