Subject: Re: bcrypt cracking on ZTEX 1.15y FPGA boards (bcrypt-ztex)
Здравствуйте!
Помогите, пожалуйста решить проблему.
Плата ztex. 1.15y.
Я установил linux mint, собрал JtR, но теперь у меня с платой не проходит
тест.
Hello!
Help please solve the problem.
The board is ztex. 1.15y.
I installed linux mint, compiled JtR, but now I do not pass the test with

Вентилятор крутится, чипы холодные. Сборка джона (magnum ripper 1.8.0.13)
прошла успешно. Opencl не устанавливал.
Запуск под sudo выводит те же результаты. Что можно сделать? Подскажите,
пожалуйста!
