Bit of a long shot. I remember using a service, which I read about on\none of the Demon groups, to test how visible and vulnerable my PC was to\nthe rest of the Internet. I'm sure it was on the Gradwell site.\n\nDoes that ring any bells? I cannot find anything now, but that is\nprobably me using the wrong terms. The service checked ports etc.,\nwhether my PC responded with lots of green and red boxes, from memory.\n\nAnyone know what I am talking about, whether it exists and where? This\nmay go back to the days of Richard Ashton.\n\nThanks!
