Hello homersux. I see ur point !!! Managed to run debugging of daemon. But , stuck at break point ? I follow CrackZ latest information , how to find the right place to break and to break ( in crackz example
lea ecx,[ebp+var_280]
push ecx <---------- Vendor code structure
.
.

In magma objdump
804adc1: 8b 45 cc mov 0xffffffcc(%ebp),%eax
804adc4: 8d 0c 85 00 00 00 00 lea 0x0(,%eax,4),%ecx
804adcb: 8b 55 d0 mov 0xffffffd0(%ebp),%edx
804adce: 29 ca sub %ecx,%edx
804add0: 89 55 d0 mov %edx,0xffffffd0(%ebp)
804add3: 8d 45 fc lea 0xfffffffc(%ebp),%eax
804add6: 89 45 cc mov %eax,0xffffffcc(%ebp)
804add9: 8b 7d f4 mov 0xfffffff4(%ebp),%edi
804addc: 89 f8 mov %edi,%eax

Its different ?
Can u help in locating and see the data and job ?
Thx in advance .
