    As a user of the aforementioned product, its important to note that
    only the management side (read: your internal network) can access
    the HTTP server of the switch (by default, though I don't even think
    you can change this.)
    
    I'm not downplaying the stupidity of cgiproc, I'm just saying lets not
    all run and turn our contivity switches off.
