All working perfect for me including aps with spaces but... i don't think reaver works for me as in the previous version was trying different pin nos. but now i am getting this:

Probably I'v done something wrong so Q: do I have to compile reaver myself or cleven is doing it if found in /home/user/.reaver

also as far as I read john can do a brute force attack (speaking about WPA handshake) to reveal an up to 8 digit alfa/numeric key so can john be setup to reveal a 8 digit capital letters A to Z (the reason I am asking is that I tried do make a word file with crunch and the size I got was 1,750GB). If this is possible can be added to Cleven. I may be wrong so please correct me.

and last, I know probably is still on your to do list but I am going to remind you anyway about the hidden aps. Thank You.
