Good night, My machine was damaged and I got the opportunity to buy new parts, including a new processor and a new GPU (r9 290x). I see some strange behavior, can you help me? 1) To install R9 290X I followed this tutorial ( http://hashcat.net/wiki/doku.php?id=linux_server_howto) and it worked. I never used hashcat, I only used jTr, but I guess the instructions to build should be the same, right? OK, my system in theory is working, please, see below: $ lspci |grep VGA 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii XT [Radeon R9 290X] $ aticonfig --adapter=all --odgt Adapter 0 - Supported device 67B0 Sensor 0: Temperature - 42.00 C Temperature is good, however this device as 67B0 is correct? What is really weird is this: $ od6config --list Adapter 0: AMD Radeon R9 200 Series R9 200? It's not my system, mine is R9 290X. I'm using driver fglrx-14.10.1006 as advised on the tutorial. The newer driver is better? Some performance related? Or update is not necessary? $ od6config --adapter=0 -get=clocks Adapter 0: AMD Radeon R9 200 Series Core (Mhz) Memory (Mhz) Current Clocks : 300 150 Min Clocks : 300 150 Peak Clocks : 1000 1250 GPU Load : 0% If I use od6config --adapter=0 --autofix the sound of the GPU cooler is a real PAIN! LOL! Is it normal? And the result is like that: $ od6config --adapter=0 --get=clocks Adapter 0: AMD Radeon R9 200 Series Core (Mhz) Memory (Mhz) Current Clocks : 1000 1250 Min Clocks : 1000 1250 Peak Clocks : 1000 1250 GPU Load : 0% I guess it's incorrect based on R9 200. Any advise guys? 2) My old computer was very slow, now with a new with 8 cores I had the chances to test some cool features such as fork. I tried it with a hash file with 10 entries that are md5crypt and sha512crypt (almost 3 md5sum and the rest sha512crypt). I tried it with a dict, like this: john --wordlist /test.txt --rules test-md5crypt-sha512crypt.hs --format=md5crypt Loaded 118 password hashes with 110 different salts (md5crypt, crypt(3) $1$ [MD5 128/128 SSE2 12x]) Press 'q' or Ctrl-C to abort, almost any other key for status 123456 (?) 123456 (?) shadow (?) biteme (?) charles (?) 5g 0:00:00:00 0.63% (ETA: 58:26:42) 2.211g/s 92.8p/s 43012c/s 8646C/s julian..morgan valerie (?) asdfasdf (?) asdf1234 (?) fashion (?) class (?) bullets (?) welcome1 (?) ashley2 (?) 13g 0:00:08:02 DONE (2014-06-24 18:44) 0.02696g/s 325.3p/s 32316c/s 34272C/s Alling..Sssing Use the "--show" option to display all of the cracked passwords reliably Session completed There are many things: A) Why is it loading 118 password hashes while I only have 10? Also, it worked on my previous box. Weird, not? B) When I type "enter" the progress bar is not displayed anymore. Is there a way to reactive it? C) Can I use it with --fork even with a wordlist? D) What are all this passwod entries followed by (?) ? Thanks
