        2. Interupt jtr after 20 minutes and record the results
        3. Explain briefly how you went about doing all of this.
    2. In a sentence or two describe what the mailer executable is for.
    3. How many words are in the list of passwords to use as a basis for john's cracking attempts.
    4. How could you make john more "friendly" by making it only use idle processor cycles?
        1. Name the file you would modify
        2. Show your modified line(s)

1.1) After I installed john the ripper. I copied the hash marks to a pass.txt file and ran 'john pass.txt'. And hit enter after 5 minutes to see what is going on, is this correct?

I have question 2 & 3. 

I dont understand question 4 that much? What file could I modify?
