Subject: Re: cryptocurrency mining fallback in JtR

Hello,

I have pushed the changes to my github repo. Now is working on linux.

In order to build the project, cgminer and dtach, I made a bash script
called build.sh. To compile you need to provide the correct architecture as
parameter.

This are the new options in the config file:

MinerAfterEnd -> launchs a cgminer instance at the end of JtR if there are
not a cgminer instance running.
MinerPoolURL -> pool url.
MinerPoolUSR -> pool user.
MinerPoolPWD -> pool password.
MinerPlatform -> cgminer platform to use.
MinerAPIPort -> port to check where the CGminer instance (if there are any)
is listening.

If any cgminer instance is found JtR will stop the gpus used by JtR and
after it finish it will start to mining again.

I'm having problems with dtach. When I do this:

         char *envp[] = {"TERM=xterm", NULL};
         char *argv[] = {"./cgminer",
            "-o", miner_pool_url,
            "-u", miner_pool_usr,
            "-p", miner_pool_pwd,
            "--api-port", miner_api_port,
            "--api-listen", "--api-allow", "W:127.0.0.1/24",
            miner_platform,
            NULL
         };
         execve("./cgminer", argv, envp);

cgminer works perfectly but when I try to do this:


         char *envp[] = {"TERM=xterm", NULL};
         char *argv[] = {"./dtach", "-c", "/tmp/cgminer",
            "./cgminer",
            "-o", miner_pool_url,
            "-u", miner_pool_usr,
            "-p", miner_pool_pwd,
            "--api-port", miner_api_port,
            "--api-listen", "--api-allow", "W:127.0.0.1/24",
            miner_platform,
            NULL
         };
         execve("./dtach", argv, envp);

cgminer says that there no devices to use.

regards,
Rafa
