Bruteforce not finding simple 4 letter hash?

[led5150]

Hey,

Yes that command did find the hash!  What is that -D flag?

Also when you say my original command is 'very dangerous' do you mean to my system?  Because I am currently running a very similar command for 24 hours now, just without the -O flag.

Please advise!  Is the above command safe to run?  (I noticed it was a very fast crack rate)

Thanks!

Matt
