+sniffit for Debian
+----------------------
+
+What follows are one of the previous maintainers, Patrick J. Edwards
+<edwards@cambridgenet.sk.ca>, thoughts on this package, and its security
+implications.
+
+Notes on Security
+-----------------
+ This program is highly dangerous, with this program hackers no
+longer need qcrack or crack for your system. Instead, they can just wait
+till a user logs in and *BAM* they have a new password. So the point is,
+this program should be promptly removed in any of the following situations:
+
+ 1. You are in doubt of the security of your system. Granted that
+ some one who has already creatively aquired (meaning hacked) root
+ can install this program his/her self there is no point in
+ pre-installing this program for them.
+
+ 2. You have a tendency to act unethically and snoop on you users for
+ no apparent reason. "Good" system admins won't do this.
+
+ 3. You don't actively search for security holes in your system. If
+ your not doing this and you box is on the Internet 24/7 perhaps you
+ should.
+
+Notes on Usage
+--------------
+ 1. Don't use this program unless you have to, and once you're done
+with it uninstall it.
+ 2. Don't scan all ports and all addresses in the hoping of catching
+a hacker cause you won't, you'll just have vast quantities of logs to search
+through and very little disk space. Instead wait till you recognize that you
+have a program user/hacker and then find out what the person is doing (how
+the hacker is trying to penetrate the system) then start using sniffit to
+collect your evidence against the offender. [I know this is flying in the
+face of traditional anti-system-terrorism policies but it leads into my next
+point]
+ 3. If you persist in using sniffit as a security net for your system
+DON'T. Plain and simple. Instead of trying to catch the hacker who has
+already hacked into your system spend your efforts security proofing your
+system (up to date versions on cron, sendmail, libraries, etc -- almost
+anything that runs as root or sudo).
+
+ The overall point is:
+ "Practice preventive medicine not reactive."
