cudaHashcat-plus64 on Debian fails when using a known password

[clamore2]

I wanted to try how well cudaHashcat plus did against aircrack, so I captured the WPA2-CCMP handshake of my own network and tried to crack it both with aircrack and cudaHashcat using the example.dict that comes with hashcat and adding my network password inside it.

Long story short, aircrack cracked it, but hashcat failed: it "Exhausted" the dictionary without recognizing the password.

My steps were:
airodump-ed a 4-way handshake between my phone and the router, wpaclean-ed it, used "aircrack <capfile> -J <hccapfile>" to generate the hccap file and launched

$ aircrack-ng -w /tmp/dic /tmp/hashcat.hccap

and

$ ./cudaHashcat-plus64.bin -m 2500 /tmp/hashcat.hccap /tmp/dic2

while the first succeded, the second resulted in:

Code:

Any ideas about why this happened?

Thanks!
