It confused me since I mostly was testing john on dual gpu systems and there it complains about lack of fork and my mind assumed -se is some magical flag that "disables" fork/node dependance :) I am already using different sessions for each john I start (even on single machine) but always use full --session so didn't notice it's basically same thing as -se. BTW your mask generation trick worked and from 5 des I got back to 2. Cracked 3 used simply two capital letters. For 2 des hashes my current setup currently needs around a year to try full ?a so those "mixed masks" really helped :) Anyway it is (as expected) clear that passwords people invent are not random and some patterns can be applied to speed up the process. It might be worth to use some neural networks to figure out those patterns but still a lot of work before this :) Regards.
