I'm starting to wonder if this is just a strange Test Suite problem. For
example, I do this:
magnum@...l:test [master]$ ./jtrts.pl -noprelim nt-opencl
-------------------------------------------------------------------------------
- JtR-TestSuite (jtrts). Version 1.12.11, July 20, 2012. By, Jim
Fougeron & others
- Testing: John the Ripper password cracker, ver: 1.7.9-jumbo-7RC
[linux-x86-64-gpu]
--------------------------------------------------------------------------------
John Jumbo build detected.
form=nt-opencl guesses: 0 unk unk : Expected
count(s) (1478) [!!!FAILED!!!]
.pot CHK:nt-opencl guesses: 0 unk unk [PASSED]
Some tests had Errors. Performed 1 tests.1 errors
Time used was 5 seconds
...so then I try this:
magnum@...l:test [master]$ ./jtrts.pl -noprelim nt-opencl -stoponerror
-------------------------------------------------------------------------------

form=nt-opencl guesses: 0 unk unk : Expected
count(s) (1478) [!!!FAILED!!!]
Exiting on error. The pot file ./tst.pot contains the found data
The command used to run this test was:
../run/john -ses=./tst -nolog -pot=./tst.pot NT_tst.in --wordlist=pw.dic
'-form=nt-opencl' 2>&1 >/dev/null
But here is what beats me. Right after the above -stoponerror, I do this:
magnum@...l:test [master]$ wc -l tst.pot
1478 tst.pot
So why does it say zero guesses? OK so I rm tst.pot and run the test as
printed:
magnum@...l:test [master]$ rm tst.pot && ../run/john -ses=./tst -nolog
-pot=./tst.pot NT_tst.in --wordlist=pw.dic '-form=nt-opencl' 2>&1 >/dev/null
OpenCL platform 0: NVIDIA CUDA, 1 device(s).

Use the "--show" option to display all of the cracked passwords reliably
WTF? First, why did I get output despite sending it to /dev/null?
Reversing the order of the redirects fixes this:
magnum@...l:test [master]$ rm tst.pot && ../run/john -ses=./tst -nolog
-pot=./tst.pot NT_tst.in --wordlist=pw.dic '-form=nt-opencl' >/dev/null
2>&1
magnum@...l:test [master]$ wc -l tst.pot
1478 tst.pot
But is that the problem? No, I did the same within jtrts.pl and it does
not change a thing. I'm out of clues. Can you spot something in the above?
Whatever is the problem, it looks like nt-opencl works just fine, and
hopefully the other three do too.
