8 I realize there is a sense of satisfaction from using the TARPIT target that
9 is appealing, however you must consider:
10
11 1. These ssh bruteforce attacks are almost certainly coming from a zombie
12 botnet, and thus there is no human to realize their connection has
13 been 'stuck'. The zombie will happily freeze for 30 seconds then try again.
14
15 2. Due to the nature of the persistant connection using TARPIT, you are
16 opening up your machine to a DOS attack, if the Bad Guy can deduce you are
17 using it.
18
19 2 cents....
