    Ok...

    what application are you trying to exploit? (if you made it, post the src unless it's too big.

    can you debug the target application? if so, debug it, and see why the shellcode is failing. From your description, the shellcode is either crashing, or failing to execute the shell (and then crashing).

    can you ktrace/strace the target application? This is a "light" way of debugging.
