Subject: [john-core] Getting John's stdout unbuffered for Johnny
In Johnny, there is an option to see console log of john. At the moment, we
have bugs because we don't get the stdout in real time and it's not in the
right order. For example, for the Loaded X hashes message, there is this
line in john.c with \n.
printf("Loaded %s (%s%s%s [%s])\n",
john_loaded_counts(),
database.format->params.label,
database.format->params.format_name[0] ? ", " : "",
database.format->params.format_name,
database.format->params.algorithm_name);
If I add fflush(stdout); after this line, Johnny will get it and print X
hashes loaded at the right time. I guess this happens with other important
strings in JtR. Could we get an unbuffered option in JtR ? Thanks.
For more details, here is the example I'm talking about:
19:59:06 : /home/math/jumbo/run/john
--session=/home/math/_john/johnny/default /home/math/3.raw-md5.pw
Warning: detected hash type "dynamic_0", but the string is also recognized
as "Raw-MD5"
Use the "--format=Raw-MD5" option to force loading these as that type
instead
Warning: poor OpenMP scalability for this hash type, consider --fork=2
Will run 2 OpenMP threads
