- 20. What is scanning?
-
- Scanning is dialing a large number of telephone numbers in the hope of
- finding interesting carriers (computers) or tones.
- Scanning can be done by hand, although dialing several thousand telephone
- numbers by hand is extremely boring and takes a long time.
- Much better is to use a scanning program, sometimes called a war dialer or
- a demon dialer. Currently, the best war dialer available to PC-DOS users is
- ToneLoc from Minor Threat and Mucho Maas. ToneLoc can be ftp'd from
- ftp.paranoia.com /pub/toneloc/.
- A war dialer will dial a range of numbers and log what it finds at each
- number. You can then only dial up the numbers that the war dialer marked as
- carriers or tones.

- 21. Is scanning illegal?
-
- Excerpt from: 2600, Spring 1990, Page 27:
- -BQ-
- In some places, scanning has been made illegal. It would be hard, though,
- for someone to file a complaint against you for scanning since the whole
- purpose is to call every number once and only once. It's not likely to be
- thought of as harassment by anyone who gets a single phone call from a
- scanning computer. Some central offices have been known to react strangely
- when people start scanning. Sometimes you're unable to get a dialtone for
- hours after you start scanning. But there is no uniform policy. The best
- thing to do is to first find out if you've got some crazy law saying you
- can't do it. If, as is likely, there is no such law, the only way to find
- out what happens is to give it a try.
- -EQ-
- It should be noted that a law making scanning illegal was recently passed
- in Colorado Springs, CO. It is now illegal to place a call in Colorado
- Springs without the intent to communicate.
