Bypass - ptrace (reverse eng)

notes.txt

1: create and compile this code 

long ptrace(int request, int pid, void *addr, void *data) {
    return 0;
}

#gcc -shared ptrace.c -o ptrace.so

2: set this env variable in both shell and gdb  :
export LD_PRELOAD=./ptrace.so

gdb: set environment LD_PRELOAD=./ptrace.so

GOOD LUCK
