Well, first off, I don't change exitserver; I change the serverloop. There's a big difference. Secondly, users can't do an exitserver to change the serverloop if they don't know the exitserver password. Thirdly, since it's also my code that's driving the printers on the host side, I can guarantee that it's my modify-serverloop job that gets to the printer first and not anyone elses. Fourthly, a successful exitserver command sends back a message that looks like: %%[ exitserver: permanent state may be changed ]%% which gives us a convenient red flag for catching any misbehaving users who have managed to figure out the exitserver password. robert -- Robert Viduya robert@shangri-la.gatech.edu Office of Computing Services Georgia Institute of Technology (404) 894-6296 Atlanta, Georgia 30332-0275
